In addition to the safety and hazard symbols the following is also used in this Operator Manual: Information ‐ This symbol accompanies notes that call attention to supplementary information that you should know and use to ensure optimal operation of the Ampt system. General Warnings: All electrical installations must be done in accordance with the local and National Electrical Code ANSI/NFPA 70. The Ampt product contains no user‐serviceable parts. For all repair and maintenance always return the unit to an authorized Ampt Service Center. Before installing or using the Ampt SPT, read all of the instructions, cautions, and warnings on the SPT, the PV array, in this Installation Page 7 of 49 Guide. Before connecting the SPT to the electrical utility grid, contact the local utility company. This connection must be made only by qualified personnel. PV arrays produce electrical energy when exposed to light and thus can create an electrical shock hazard. Wiring of the PV‐arrays should only be performed by qualified personnel. Page 8 of 49 MARKINGS SERVICING Warnings: 1. 2. 3. 4. 5. 6. When the photovoltaic (PV) array is exposed to light, it produces a DC voltage, and the Ampt equipment is energized. Servicing instructions are for use by qualified personnel only. To reduce the risk of electric shock, do not perform any servicing other than that specified in these Operating Instructions. The installation of Ampt equipment requires following the National Electrical Code (ANSI/NFPA 70) wiring methods. CAUTION: To reduce the risk of fire, connect the outputs of the Ampt Equipment only to conductors with a minimum ampacity of 9.4 amperes when de‐rated for temperature and conduit fill. Over‐current protection devices and conductors shall be sized in accordance with the National Electrical Code (ANSI/NFPA 70). Ampt requires over current protection for the DC output circuit in the installation. Ampt recommends that a disconnect switch be included in the installation for the DC input and DC output circuit as required by the local authorities. Page 9 of 49 7. MESSAGE FROM AMPT The first products that Ampt is introducing are a result of looking at requirements to realize maximum energy at the lowest cost – from a system level perspective. This initial premise is that the maximum energy cannot be harvested fully without the right granularity. We believe that this requires power conversion to be done at the module level. Our customers require minimal lost harvest from local soiling, shading, or panel imbalance– so with regards to local power conversion, there is no more suitable economic alternative. We believe that the power conversion has to be extremely efficient over a very wide range – so our products are over 99% efficient over greater than 3:1 input range. To put that into context, the Ampt SPT consumes only, up to 2W of the energy generated by a 200W module – relatively speaking that is the same loss as expected from energy traveling through 3 feet of conventional wire cabling. We believe that high speed MPP is very critical to maximize harvest – we have over 99.9% accurate MPP in 100 milliseconds. Therefore, we can capture the power gain from the edge of a cloud and the refracted irradiation on a module. We believe that maximizing the number of modules per string is important. The Ampt product is dynamically controlled, and we can communicate wirelessly to our field adaptable firmware. We believe that reliability is a huge drive of economics – so we have an environmentally validated (not superficially modeled) 1000 year MTBF. We believe that high accuracy and stable instrumentation combined with robust communication is crucial for large‐scale arrays and beneficial for all smaller arrays. It lowers installation costs, and radically reduces O&M while maximizing the economics of harvesting. We have a better than 1% field calibrate‐able measurement system that includes multiple channels of critical electrical and temperature parameters, as well as identity information – per module. We believe that communication alone isn’t sufficient. These applications need scalability and robustness that does not depend on problematic connections. We designed a highly robust wireless system. We believe that if the system is designed with the right granularity, with the right components, with the right interfaces and the right architecture that it becomes unlimited in its ability to operate at any scale. We have designed this system to allow scaling from one module to above a million modules. Thank you for Continued Support – we look forward to working with you! We are Ampt. Page 10 of 49 WHY SPT – WHY GET AMPT? What is maximum power? Is it defined by the energy output of the weakest module in a string, or the combined output of every single module on every string? Is it defined by analyzing energy harvest each day at one site, or every second on every panel at one million sites? Is it defined by the monitoring of information within an array, or the communication of knowledge that leads to improved performance within every module? By answering what no one else has even yet asked, Ampt is not just increasing energy, but helping you to realize energy you never knew possible. Congratulations on putting the absolute best communications and power conversion equipment available on your PV system! Page 11 of 49 SMART PANEL TECHNOLOGY OVERVIEW Ampt has developed Smart Panel TechnologyTM ‐ SPT ‐ as the optimal solution for energy harvesting from any PV system. The first implementation of Ampt SPT is in a standalone device that is placed in direct connection with the PV module to deliver MPPT (Maximum Power Point Tracking) which is the harvested energy. Conventional PV systems have solar modules series connected, and are thereby limited by the weakest module in the string. These strings are wired to a bulk DC‐AC inverter which uses algorithms to attempt a maximum harvest given the potential from each string. Page 12 of 49 The Ampt SPT puts the MPPT logic where it belongs, on each solar module, and allows each module to produce its maximum power. Then each SPT device combines to provide the bulk inverter with its highest efficiency input power. The result: the highest energy from each module, operating with the highest efficiency of the bulk inverter. IN SIMPLE TERMS, THE SPT: Receives the power from the module at its Maximum Power Point Tracking (MPPT) regardless of normal or problematic operating conditions Delivers module MPPT power into any impedance determined by the remainder of the string and the inverter Solves the problem of having panels (current sources) in series being limited by the weakest panel in the string‐ improves string sighting options Ensures every panel produces whatever it can regardless of the remainder of the system Allows the inverter to operate at its highest efficiency point Provides wireless communication on each module, reporting more than just panel voltage, current and temperature. Additional information is resident such as module serial number and manufacturing information Wireless communication also provides diagnostic information for maintenance, and through radio commands the output can be turned on/off Page 13 of 49 HERE’S HOW IT WORKS: Each solar module will have a dedicated Ampt SPT device connected to the module outputs. The Ampt SPT devices then are connected in series to each other and will make up a “string” of modules. Each string is then combined in parallel to connect with the bulk inverter (in today’s conventional array). When solar rays are absorbed by the PV module, energy is produced. The SPT maximizes the harvestable energy from each PV module, and converts it to a useful output that is then delivered to the string (regardless of the environmental or operational conditions affecting that particular panel). The strings are then combined as an array and delivered to the bulk inverter at its pre‐determined impedance requirement. It is important to note that the conventional bulk inverter dynamically is searching for MPPT (maximum power point tracking), and may change its impedance requirements every 4+ seconds. The Ampt SPT however is adjusting its MPPT 8 times per second to again maximize the harvestable energy produced on each PV module. In conventional PV installations (without the Ampt SPT), with series connected modules, one weak link in a string causes significant energy harvest degradation, and will lower the produced power produced. If there is sufficient obstruction to the amount of solar insolation absorbed by a single module (or over several modules), it is possible that the entire string collapses (electrically), and nets zero power output. The Ampt SPT solves this problem by maximizing the power harvest at each module regardless of the conditions, and converts that to a viable output thereby eliminating the weakest link phenomenon. With Ampt SPT, even a low power producing module is valuable, and contributes to the net power generated. Of course, if the module is damaged or obstructed to the point where its internal circuit cannot produce power, Ampt SPT cannot correct this condition. With the wireless communication link though, the owner operator can identify this condition, and make the necessary corrections. In the meantime though, the balance of the string is still operational and generating as much power as required by the bulk inverter. Each SPT is accessible by a host computer through a wireless AND “gateway” interface. This gateway allows the owner/operator to speak specifically to each SPT, and provides a bi‐directional wireless communication link which is the vehicle for command / control and data acquisition. The AND GUI (graphical user interface) is then utilized to observe the performance and control the SPT operations. Examples of this GUI are shown below: Page 14 of 49 The GUI has a lot of data presented and will likely change for increased usability, but at present demonstrates the kind of interaction and reporting available. As you can see, each module (and corresponding SPT) is mapped out per their installed location. Note: each SPT is bar coded, and during the field commissioning process, a bar code scanner can be utilized to logically map out the organization of modules. It is also possible that the bar code reader can interface to the SPT through a separate gateway, and thereby control its on/off state for field personnel safety. That’s it. With a simple installation, the Ampt SPT products operate immediately and automatically enhance the power generated by the PV installation. Ongoing monitoring and command control features are available to the owner operation, but regular interaction is not required to get maximum power. Page 15 of 49 THEORY OF OPERATION The Ampt SPT is designed to mitigate irregularities between the modules in an array and the bulk inverter. Specifically, the SPT can fix its output to match the optimal inverter input voltage and broaden the performance range of conventional PV modules & inverter combinations. By providing localized DC‐DC conversion along with wireless communication, the SPT enables instantaneous control and feedback to the system and thereby maximizes energy harvesting. SPT FUNDAMENTALS: • The SPT module puts MPP where it belongs, on every panel, and produces the maximum power that is available regardless of panel condition, and regardless of the remainder of the system. If there is partial shade, dirt or panel imbalance, every panel still puts out its maximum power. • The SPT module receives the power from the panel at MPP. It delivers the power to any impedance determined by the remainder of the string and the inverter. This solves the problem of having panels (current sources) in series being limited by the weakest panel in the string. • The conventional bulk power inverter may impress any voltage it wants and because the SPT is deployed as a localized DC‐DC converter, the panel field will simply output MPP from every panel. This allows the inverter to operate at its highest efficiency point. • Going forward, SPT based installations can enable better bulk inverter designs that deliver higher efficiency, greater reliability, smaller and lighter as they would no longer be required to include an MPP stage. • One of the most significant elements of the SPT is the inherent wireless communications capabilities, which enables instantaneous communication and control. The radio and ubiquitous wireless mesh network formed by SPT modules will not only report panel voltage, current and temperature, but also provide operational benefits by toggling the panel outputs on and off. • Other information could also reside there such as serial number and manufacturing information. • The wireless radio will also provide diagnostic information for maintenance and trend analysis thus allowing intelligent decisions on what requires service and when.

(MBTF of 90M hrs means a failure rate of 0.01% PER 25 YEARS (warranty period) assuming 10 hours of operation per day at 40C ambient). THIRD PARTY VALIDATION 1. 2. 3. Sandia SWTDI (NMSU) BEW ??? ??? Test reports will be made available upon request Page 18 of 49 SAFETY AND CONVENIENCE FEATURES Currently, one problem facing installers and maintenance providers of PV Systems is safety. Since conventionally, all panels are connected in series and installation and maintenance work is done during periods of irradiance, the voltage across the panels might reach dangerous levels exposing field personnel to a real danger of electrocution. Ampt provides a “convenience” mode which supports an “on / off” mode of operation. This mode of operation essentially enables or disables the SPT output and can facilitate system installer/operators during installation, diagnostics, and maintenance tasks. It is important to recognize that this is a electrical circuit logic change and is not to be confused with a hard switch. This convenience feature is designed to enhance the protection of module handlers, including the installer, maintenance provider and potentially emergency personnel (ie. Fire Department)."

I NTRODUCTION : There are two views available for managing your Solar Array; summary and string view. The Summary view provides an overview of the state of the solar array. It includes current DC energy output in Watts, Volts, and Amps, power by string, SPT status, and estimated AC Power. The String view provides detailed information on the performance of each SPT. It provides performance information at the string level; DC energy output in Watts, Volts, and Amps. Both views automatically refresh about every 15 seconds. D ETAILS S UMMARY V IEW The Summary page (figure 1) presents information at the array level. The button across the top “Lock/Unlock Whole Station” allows you to disable commands to the system. This is useful as a safety precaution when servicing the station. To the right is the time the information your viewing was last updated. This is based on your local computer’s time. The strings are organized around the physical and logical layout as closely as possible and list the status of the module, on or off, and status of the Maximize Power Point feature, MPP, on or off. Clicking on the string and module area will take you to the String View. Below the string and module area is a bar chart showing the power output for each string in the array. The power output details for the array are shown on the right edge; including estimated kW hours. At the bottom is a graph of Energy, power and temperature. The scale for the temperature is listed on the right edge of the graph. You can position your mouse over the lines to see the time and value of the measurement. The time scale of the graph can be changed using the controls to the right of the graph. You can change the time interval as well as go back and forward time periods.
