The Intelligent Wireless Sensor Suite Luna iMonitoring’s Intelligent Wireless Sensor Suite includes sensors, computers, software, and communication devices to collect and transmit data in a variety of industries and applications. The iMonitoring “smart” sensors use local processing to minimize power consumption and communication bandwidth. Intelligent software collects, processes, and stores the data in an information database. The iMonitoring system uses RF, cellular, Internet, and satellite links to transmit data between sensors, data collection sites, and central computers. For more information on the Intelligent Wireless Sensor Suite and its components, please visit the Luna iMonitoring web site at www.lunaimonitoring.com WEMS Components The current configuration of the WEMS includes one or more of each of the following components: • Concentration and Communications Unit (iCCU), • Compact Flash Radio (iCFR), • Electronic Flow Monitor (iEFM) • Tank Level Monitor (iTLM-1), • Wellhead Pressure Monitor (iWPM-T), • Secure Digital (SD) Card containing the WEMS Software.
WEMS Installer’s Guide 3 Introduction Figure 2. Luna iMonitoring’s Wireless Oil Field. The following sections discuss features of each component. For detailed specifications see Appendix A, “Specifications”. Concentration and Communications Unit (iCCU) The Luna iMonitoring iCCU is an autonomous, wireless-LAN-to-wireless-WAN bridge, and data storage and collection unit. Data flows via a secure, bidirectional, local radio link. The iCCU can perform on-board data storage and processing, and can serve as a LAN repeater. It contains external WAN and LAN antenna ports. A single, solar-assisted battery powers the unit which optimizes power based on the current energy storage. The iCCU supports up to 128 wireless sensors, and is installer configurable and upgradeable. Compact Flash Radio (iCFR) The Luna iMonitoring iCFR is a self-contained Type I Compact Flash Radio for wireless sensing applications. The iCFR uses a
WEMS Installer’s Guide 4 Introduction standard interface found on PocketPC®s. The unit communicates with iCCUs, and iMonitoring’s sensors over a wireless interface. The iCFR does not require a battery since the host unit provides power. Other features include programmable output power to an upper limit as defined in Appendix A, low cost, and the ability to configure and upgrade the unit by the installer. Electronic Flow Monitor (iEFM) The Luna iMonitoring iEFM is an autonomous, wireless electronic flow monitor which monitors natural gas flow and provides total volumetric flow rate. Typically, the sensor acquires five flow readings per day in monitor mode. Each reading consists of an instantaneous measurement, an average over the previous hour, and an average over the previous 24 hours. An iCCU may interrogate an iEFM at any time within a range of 2500 feet, and a portable device, such as a PocketPC®, can poll the unit within a range of 500 feet. The iEFM performs on-board data storage and processing, and transmits over a secure, bidirectional radio link. The unit optimizes power based on the current energy storage, and requires only a single, solar-assisted battery. The iEFM is easy to install, and is installler configurable and upgradeable. The unit incorporates an IP65 ruggedized enclosure and meets UL-913 certification requirements for an intrinsically safe device in Class I, Division 1, Groups C and D hazardous areas. Tank Level Monitor (iTLM-1) The Luna iMonitoring iTLM-1 is a self-contained, wireless tank level monitor using Ultrasonic Sensing Technology to provide temperature-compensated fluid level measurements in tanks and silos. Typically, the sensor acquires five pressure readings per day in monitor mode. An iCCU can communicate with a iTLM-1 within a range of 2500 feet, and a portable device, such as a PocketPC®, can poll the unit within a range of 500 feet. The iTLM-1 performs on-board data storage and processing, and transmits over a secure, bidirectional radio link. The unit optimizes power based on the current energy storage, and requires only a single, solar-assisted battery. The iTLM-1 is easy to install, and is installer configurable and upgradeable. The unit incorporates an IP65 ruggedized enclosure and meets UL-913 certification requirements for an intrinsically safe device in Class I, Division 1, Groups C and D hazardous areas.
WEMS Installer’s Guide 5 Introduction Wellhead Pressure Monitor (iWPM-T) The Luna iMonitoring iWPM-T is an autonomous, wireless pressure monitor for sensing pressure at the wellhead in oil and gas applications. Typically, the sensor acquires five pressure and temperature readings per day in monitor mode. An iCCU may interrogate an iWPM-T at any time within a range of 2500 feet, and a portable device, such as a PocketPC®, can poll the unit within a range of 500 feet. The iWPM-T performs on-board data storage and processing, and transmits over a secure, bidirectional radio link. The unit optimizes power based on the current energy storage, and requires only a single, solar-assisted battery. The iWPM-T is easy to install, and is installer configurable and upgradeable. The unit incorporates an IP65 ruggedized enclosure and meets UL-913 certification requirements for an intrinsically safe device in Class I, Division 1, Groups C and D hazardous areas. Secure Digital (SD) Card The SD Card supplied with the system contains the WEMS Software for a PocketPC® running version 3.0 of the PocketPC® operating system. The SD Card plugs into the standard SD slot found on all PocketPC®s. The WEMS Software requires a one-time installation per PocketPC®, and includes programs for defining, accessing, and interrogating multiple iMonitoring devices. Chapter 3, “WEMS Software”, includes a detailed discussion on the installation and use of the WEMS Software. User-supplied Components For on-demand sensor measurements and data acquisition in the field, the user must supply a PocketPC®, such as the one shown at the left, to interrogate the iCCU, iWPM-T, and iTLM-1. The PocketPC® must have a CF Card slot to accommodate the iCFR, and an SD slot for the WEMS Software SD Card
6 Chapter 2 Installation The components in Luna iMonitoring’s Intelligent Wireless Sensor Suite are easy to install using simple tools. The installation guidelines in this manual outline the steps for selecting the proper site for the device, and for handling, mounting and activating the device. Site Selection for WEMS Components The iTLM-1 and iWPM-T sensor modules mount directly onto oil and gas tanks, pipelines, and wellheads in the field. The iCCU mounts on a variety of structures in and around the oil field. Issues affecting the site selected for installation include obstructions in the line-of-sight between the sensor module and the iCCU; distance from the sensor module to an iCCU; height of the iCCU; proximity of the component to other electronic equipment or large metal objects that may affect the transmission of radio signals; orientation of the solar panels on the component; hazardous environmental conditions; and the surface mounting angle of the tank for the iTLM-1 installation. Guidelines Concerning RF Signal Transmission Luna iMonitoring’s sensor modules use RF signals to communicate with iCCUs and PocketPC®s. Following the guidelines below maximizes the range over which the WEMS components will be able to transmit signals. • Place the sensor module in the direct line-of-sight with the iCCU, whenever possible. A direct line-of-sight between the sensor module and the iCCU provides optimal signal transmission and reception. With a direct line-of-sight, the WEMS components communicate up to 2500 feet. However, without a direct line-of-sight, this distance decreases. • Place the iCCU as high as possible to improve signal transmission and reception. • Avoid placing sensor modules and iCCUs near electrical equipment or large metal objects. Electrical devices, such as large electric
WEMS Installer’s Guide 7 WEMS Software motors, power lines, antennas, and electric fences cause electro-magnetic interference that adversely affect signal quality. Large metal objects, which are electrically conductive, reflect and scatter radio signals when placed between two RF-linked modules. The Luna iMonitoring sensor modules, iCFR and iCCU meet FCC requirements for CFR 47 Part 15, which dictate that operation of the device is subject to the following two conditions: 1) The device will not cause harmful interference, and 2) The device must accept any interference received, including interference that may cause undesired operation. Because the device meets FCC requirements for CFR 47 Part 15, the customer requires no operating license to transmit radio signals using the device. To comply with current FCC RF Exposure limits, the antenna used for the Luna iMonitoring iCCU, iEFM, iTLM-1, and iWPM-T transmitter must be installed to provide a separation distance of at least 20 cm from all persons. The Luna iMonitoring iCFR, iEFM, iTLM-1, and iWPM-T must not be co-located or operating in conjunction with any other antenna or transmitter. The Luna iMonitoring iTLM-1 sensor module utilizes ultrasonic technology and is subject to the following additional authorization: Verification as a non-consumer ISM device as specified by Part 18. The Luna iMonitoring iCCU is subject to the following additional authorization: Verification as a transmitter as specified by Part 25. Any changes or modifications not expressly approved by the manufacturer will void the user’s authority to operate the equipment. Every radio-linked device in the Luna iMonitoring Intelligent Wireless Sensor Suite carries a label. Figure 3 below shows a typical label for a sensor device which includes the Model Number of the device, the FCC ID Number, the UL certification, the FCC certification(s), and the Serial Number.
WEMS Installer’s Guide 8 WEMS Software Figure 3. Typical Label Found on all Luna iMonitoring Radio-linked Devices. Guidelines Concerning Solar Panels All of Luna iMonitoring’s sensor modules and iCCUs employ a single, solar-assisted battery for power. Properly orienting the solar panels on the WEMS component achieves a maximum battery life of more than two years. Place the component in a non-shaded area with the solar panels facing toward the sun. Also, ensure that the site chosen will not become shaded due to tree growth or installation of other structures. Guidelines Concerning Hazardous Environments Luna iMonitoring sensor modules mount directly onto structures such as a tanks, pipelines, or wellheads located in hazardous areas. These sensor modules (iEFM, iTLM-1, and iWPM-T) are, by design, intrinsically safe and meet the standard for UL-913 certification for Class I, Division 1, Groups C and D hazardous areas. By definition, an intrinsically safe apparatus is one in which all the circuits are intrinsically safe; and an intrinsically safe circuit is one in which any spark or thermal effect is incapable of causing ignition of a mixture of flammable or combustible material in air under prescribed test conditions, according to the National Electrical Code. The iCCU mounts onto structures outside the hazardous zones in the oil field; for example, an area greater than 3 meters from an oil tank. Guidelines Concerning iTLM-1 Mounting The iTLM-1 uses Ultrasonic Sensing Technology to provide tank fluid level measurements. The sensor projects an ultrasonic beam at the surface of the liquid in a tank. The beam reflects off the liquid’s surface back to the sensor. The iTLM-1 acquires the raw measurement and then compensates for the effects of temperature on the raw data. To properly measure the fluid level in the tank,
WEMS Installer’s Guide 9 WEMS Software the sensor must be mounted such that the path of the ultrasonic beam is perpendicular to the fluid surface. A mounting angle greater than 5 degrees may cause erroneous data. Figure 4 below provides a rendering of a properly installed iTLM-1 sensor module. Figure 4. Proper Mounting Angle for the iTLM-1 Sensor. Pre-installation iTLM-1 Depth Calibration Before installing the iTLM-1 sensor device on a tank, perform the iTLM-1 depth calibration procedure. See the section on the iTLM-1 Depth Calibration in Chapter 3, “WEMS Software”, for details. Installation Instructions When installing any of the iMonitoring wireless devices care must be taken to guarantee that the wireless devices are installed and provisioned in its intended configuration and the installation guarantees compliance to regulatory and safety requirements.

Once Sync to PC is enabled, select the Set Parameters button and wait for the progress screen to complete. 5) Verify that the setting was accepted by checking the Current Device Settings window. iCFR Installation Instructions The following instructions are to be performed for the iCFR at installation. 1) Install the WEMS Software on the PocketPC® to be used with the iCFR as described in Chapter3, “WEMS Software”. 2) Remove the iCFR packing carton. 3) Insert the iCFR into the Compact Flash Card slot of the PocketPC®. 4) The iCFR is now ready for use as described in Chapter3, “WEMS Software”.
WEMS Installer’s Guide 12 WEMS Software Chapter 3 WEMS Software The WEMS Software is a multi-purpose, menu-driven program for configuring and accessing all modules in Luna iMonitoring’s Intelligent Wireless Sensor Suite. Once properly configured using the WEMS Software, the devices run autonomously based on the scheduling parameters set in the software. The WEMS Software also provides in-the-field access to any device. The following sections include procedures for initializing all WEMS modules, and instructions for interrogating these devices in the field. Installing the WEMS Software (a) (b) Figure 5. (a) SD Card; (b) iCFR The WEMS Software runs on a PocketPC® using the SD Card provided by Luna iMonitoring. The PocketPC® communicates with the sensors and iCCUs using the iCFR also provided by Luna iMonitoring. The user supplies the PocketPC®, which must contain a CF slot and SD slot, and must run PocketPC® Version 3.0 or higher. Follow the steps below to install and initialize the WEMS Software. 1) Insert the iCFR into the CF slot on the PocketPC®.
WEMS Installer’s Guide 13 WEMS Software 2) Insert the SD Card containing the WEMS software into the SD slot on the PocketPC®. 3) Access the files on the SD Card. The SD Card will contain two programs as shown in Figure 6 below. Figure 6. WEMS Software Programs on the SD Card. 4) Execute either one of the programs. 5) The first time the program runs, it will ask for the location of the iCFR as in Figure 7 below.
WEMS Installer’s Guide 14 WEMS Software Figure 7. iCFR Serial Port Selection Menu. Typically, the CF slot is located on COM2 or higher. Select COM2 from the Serial Port pull-down list and click OK. If the iCFR is on COM2, the program’s main menu will open. If the iCFR in not on COM2, the program will return to the Start menu and wait for another port selection. Try other available ports until the program finds the iCFR port and opens the main menu.
WEMS Installer’s Guide 15 WEMS Software PocketConfig The program PocketConfig includes menus for configuring and interrogating devices. Before the PocketPC® can communicate with sensor and communication devices, it must have certain information about the device. Therefore, the software will not list any sensors at initial start-up of the program as in Figure 8. Figure 8. PocketConfig Main Menu with No Defined Devices.
WEMS Installer’s Guide 16 WEMS Software Adding New Devices Every Luna iMonitoring device has a unique serial number found on the Luna iMonitoring Serial Number label attached to the device. The software identifies each device by its unique serial number. The sensor list contains the serial numbers of the last ten devices accessed by the software. To add a device to the sensor list, enter the unique serial number of the device in the space provided and hit the “<” button. If the sensor list already contains ten serial numbers as in Figure 9 below, then the least recently accessed device drops from the sensor list. To interrogate a sensor already in the list, simply select the proper serial number from the list and hit the “>” button to copy the serial number into the Serial Number field. To access a sensor not in the list, type its serial number in the space provided. The software automatically adds the serial number to the list when the Configure button is selected. To clear the selected sensor from the sensor list, hit the Clear button. Figure 9. PocketConfig Main Menu.
WEMS Installer’s Guide 17 WEMS Software Sensor Charge Modes Sensor devices have four charge modes based on the current charge capacity of the device’s battery. The four modes are • Always On mode, when the battery is at 100%; • Fast mode, when the battery is above 76.7% but below 100%; • Slow mode, when the battery is at or below 76.7% but above 0%; • Always Off mode, when the battery is fully discharged. The device stays on continually in Always On mode which usually occurs on sunny days when the solar panels can power the device and keep the battery fully charged. In Fast mode the device “wakes up” every 10 seconds to see if it is being interrogated. In Slow mode the device only wakes up every 2 minutes. If the battery becomes fully discharged, then the device shuts off completely. Setting the Default ReSync Time The ReSync Time selected in the setup menu determines how long the software waits for a response from a device. To access this menu, select the Setup tab on the main menu, and hit the Options button shown in Figure 10 below. Figure 10. Accessing the Setup Menu. Figure 11 shows the setup menu and the ReSync Time options. If Wait for devices in fast mode is selected, the software waits for 11 seconds to access a
WEMS Installer’s Guide 18 WEMS Software device. Devices usually “wake up” every 10 seconds in Fast mode; therefore, searching for 11 seconds should find the device. If Wait for devices in slow mode is selected, the software waits for 121 seconds. The device may be in Slow mode and will only “wake up” every 2 minutes. If Custom wait time is selected, enter a wait time in milliseconds in the space provided. Once the proper mode is chosen, hit the OK button to set the ReSync Time option. Figure 11. ReSync Wait Time Selection Menu. Finding Sleeping Devices If a known device does not respond when interrogated, the device may be “sleeping”, and the Resync Time may be set to only wait for devices in fast mode. By default, the software searches for the device for the time interval specified in the setup menu. To wake a sleeping device, enter its serial number in the appropriate space under Find Sleeping Sensors in the main menu, and hit the Wake button. If the software still does not find the sleeping device, increase the search time to 121 seconds. If the software fails to find the device after 121 seconds, check the device for possible battery failure. Using Find Sleeping Sensors overrides the time interval selected in the setup menu. Note: Find Sleeping Sensors wakes the device and places it temporarily in Always On mode which significantly increases power consumption.
WEMS Installer’s Guide 19 WEMS Software About PocketConfig Luna iMonitoring includes information on each of its software programs that is accessed by selecting the Help tab at the bottom of the screen and hitting the About button as shown in Figure 12 below. Figure 12. Accessing the About PocketConfig Menu.
WEMS Installer’s Guide 20 WEMS Software The window shown in Figure 13 provides copyright and version information on the program and library software. Figure 13. Detailed Information on PocketConfig.
WEMS Installer’s Guide 21 WEMS Software Configuration Menus Luna iMonitoring preconfigures the settings for all its devices. To view the current settings or to reconfigure the device, select the device in the main menu and hit the Configure button to bring up one of the menus shown in Figure 14. Menu (a) shows the sensor configuration menu for an iWPM-T, but other sensor configuration menus contain the same information and options. The sensor menu includes the serial number for the iCCU to which the sensor uplinks. If the CCU field contains all zeros, as in Figure 14, then the sensor broadcasts to all listening iCCUs. Menu (b) shows an iCCU configuration menu which does not include the CCU field. (a) (b) Figure 14. Configuration Menus for an (a) iCCU, and an (b) iWPM-T. To change a parameter value, first highlight the value with a single tap, then enable the value for editing with another tap. Now select the keyboard entry screen by tapping the keyboard icon at the bottom right of the screen. Use the keyboard to enter the new value. When finished entering the data, exit the keyboard by tapping the icon again. DO NOT USE THE “ENTER” KEY, as this will cause the application to exit. Once all the new parameter values are entered, hit the Set Parameters button to accept the changes. Parameters shown in
WEMS Installer’s Guide 22 WEMS Software brackets, [ ], in the Current Device Settings window may not be changed. The new values will appear in the Current Device Settings window. To change Amp Mode, select an option, Low/Medium/High, from the pull-down list. To change XmitPower, use the up/down arrows to the right of the field. The Amp Setting and XmitPower controls are available only to reduce the power below the authorized limits stated Appendix A of this document when desired, the control will not allow power greater than the authorized limits. To uplink a sensor to a specific iCCU, enter the serial number of the iCCU in the CCU field, or enter all zeros to broadcast to all iCCUs in listening range. The Sync to PC option synchronizes the Real Time Clock on the device to the clock on the PocketPC®. Use this option to synchronize all devices in the field to the same clock. Normally, Day Begin and Day End are set to 12:00 AM. To change these parameters, use the up/down arrows to the right of the field. These parameters only increment in 1-hour intervals. The Current Device Settings window provides other valuable information that is accessible using the scroll bar. Figure 15 below shows the Current Device Settings window for an iTLM-1 when scrolled down to reveal additional parameters. This other information includes: • the device serial number; • a 4-byte encryption key, called the cypher, which must be the same for all devices in a network; • the home channel that the device waits on when there is no activity, (when active the device scans all channels, 0-52); • the modulus through the scanning sequence, called the DSS skip, that can create additional sequences and must be the same for all devices in a network, (usually set to 1); • the version number of the device’s firmware.
WEMS Installer’s Guide 23 WEMS Software Figure 15. Current Device Settings Continuation Window for an iTLM-1. Each device uses a different set of menus for configuring additional parameters. To access these menus, select one of the tabs along the bottom of the screen. Some menus are similar for all devices, and some menus are device-specific. All devices have menus for configuration, uplink scheduling, updating firmware, setting advanced parameters, and testing the device’s radio. The iCCU has a status menu and an uplink menu, and sensor devices have calibration menus and a data menu.
WEMS Installer’s Guide 24 WEMS Software Uplink Scheduling Menu The WEMS devices run autonomously according to the uplink schedule set in the uplink scheduling menu. Sensors uplink to an iCCU, and an iCCU uplinks to a computer via satellite. To access this menu, select the Sched tab as shown in Figure 16 below. The software allows for four time schedules. For each time schedule, the software allows three pull-down options - Enabled, Disabled, or Hourly. In the Enabled mode, the device uplinks once daily at the time specified. In the Hourly mode, the device uplinks every hour at the minute/second specified. Normally, Hourly mode is only used for testing purposes. To change the time, click on the desired field, (hour, minute, second, AM/PM), and use the up/down arrows to change the field. Once the desired schedules and times are entered, hit Set Uplink Times to accept the changes. Sensor devices must uplink to an iCCU at specific time intervals when the iCCU accepts data uplinks. The iCCU is active for one minute every ten minutes “on the tens” of every hour. In other words, the iCCU is active from 00 min. 00 sec. after the hour to 01 min. 00 sec. after the hour; from 10 min. 00 sec. after the hour to 11 min. 00 sec. after the hour; from 20 min. 00 sec. after the hour to 21 min. 00 sec. after the hour; etc. Therefore, synchronizing the real-time clocks on all devices and properly scheduling the uplink times on sensor devices are very important. When setting the uplink time on a sensor device, keep in mind that, over time, the real-time clock may drift out of synchronization by a few seconds. Therefore, do not select an uplink time that is too close to the beginning or end of the uplink time window. Choose a value for the seconds field that falls between 15 and 45 seconds as in the example in Figure 16. Also, if the iCCU is linked to several sensor devices, space the uplink times for each device about five seconds apart to keep two devices from uplinking at the same time.

To get the current status, select the Status tab and hit the Get Status button. The Charge field indicates the current charge of the battery. Fast Mode Level is the battery charge level below which the device switches from Fast Mode to Slow Mode, and the Always Off Level is the level where the device shuts itself off. Under Uplink Status, Last Uplink indicates the time of the most recent uplink to the satellite, and Next Uplink indicates the scheduled time for the next uplink. A Status code of 0x00 indicates that the last uplink was successful. Figure 20. iCCU Status Menu.
WEMS Installer’s Guide 32 WEMS Software iEFM-Specific Menus The iEFM tabs include menus for calibrating the sensor and the gas element on the iEFM device. Figure 21 below shows the menu for calibrating the sensor, and Figure 22 on the following page shows the gas element calibration menu. This section also discusses the iEFM sensor data window. iEFM Sensor Calibration The iEFM operation requires a number of parameters for valid measurements that are entered using the sensor calibration menu shown in Figure 21 below, which is accessed by selecting the Sensor Cal tab. The values for Temp cal intercept and Temp cal slope are entered at the factory and are matched to the external sensor that is supplied with the iEFM. The other parameters are dependant on the process equipment to which the iEFM is attached. Figure 21. iEFM Sensor Calibration Menu.
WEMS Installer’s Guide 33 WEMS Software iEFM Gas Calibration The process gas consists of multiple gas concentrations. The iEFM operation requires that each gas element percentage of concentration be entered for valid measurements.

Enter the correct Slope and Intercept, and hit the Set Calibration button. Figure 25. iTLM-1 Distance Calibration Menu.
WEMS Installer’s Guide 37 WEMS Software iTLM-1 Depth Calibration The iTLM-1 depth calibration must be performed during the process of installing the iTLM-1 sensor device on the tank. At the time of the device installation, the iTLM-1 needs to know the exact depth of the fluid in the tank to perform the depth calibration for the tank level sensor. To set the depth calibration parameter, select the Depth Cal tab at the bottom of the screen to access the depth calibration menu shown in Figure 26 below. Enter the current depth of the fluid in the tank in inches in the Measured Depth field, install the iTLM-1 sensor, and hit the Set Depth Cal button. Once the depth calibration is complete, the value “-2” appears in the Measured Depth field to block any inadvertent changes to the calibration parameters. Luna iMonitoring personnel use the “-1” value, which removes the depth calibration and reports distance. This is useful when performing the distance calibration. Figure 26. iTLM-1 Depth Calibration Menu.
WEMS Installer’s Guide 38 WEMS Software iWPM-T-Specific Menus The iWPM-T tabs include menus for calibrating the pressure and temperature sensors on the iWPM-T device.

55 Appendix C Using the Charge Cable Figure 38. WEMS Charge Cable. Luna iMonitoring provides a device Charge Cable, shown in Figure 38 above, with most Beta Test versions of the Wireless Enabled Monitoring System. The Charge Cable is for use in a lab setting and is not tested or approved for use in hazardous environments. The Charge Cable has an SMA connector at one end and a USB connector at the other end. The SMA connector plugs into the SMA antenna connector on the WEMS device being tested. The antenna on each WEMS device simply screws off of the SMA connector. The USB connector plugs into the USB port of any computer. The SMA connector serves as an antenna connection as well as a power connection. Therefore, the device receives power from the USB port on the computer when the computer is on. Even though the antenna is disconnected, the device can still receive and transmit radio signals in a lab setting. The Charge Cable serves two purposes: 1) It quickly charges the battery to full capacity. 2) It maintains a full charge on the battery in a lab setting where the solar panels can not charge the battery.
