Tous les modules doivent être connectés à un optimiseur de puissance. CAUTION! If you intend to mount the optimizers directly to the module or module frame, first consult the module manufacturer for guidance regarding the mounting location and the impact, if any, on module warranty. Drilling holes in the module frame should be done according to the module manufacturer instructions. ATTENTION! Pour installation à même le module ou la monture du module, consultez d'abord le fabricant du module sur la position et son impact sur la garantie du module. Le perçage de trous dans le cadre du module devra se faire suivant les instructions du fabricant. StorEdge Solution with Backup MAN-01-00262-1.5 22 Safety CAUTION! Installing a SolarEdge system without ensuring compatibility of the module connectors with the optimizer connectors may be unsafe and could cause functionality problems such as ground faults, resulting in inverter shut down. To ensure mechanical compatibility of the power optimizers' connectors with the PV modules' connectors to which they are connected: Use identical connectors from the same manufacturer and of the same type on both the power optimizers and on the modules; or Verify that the connectors are compatible in the following way: The module connector manufacturer should explicitly verify compatibility with the SolarEdge optimizer connector; and A third-party test report by one of the listed external labs (TUV, VDE, Bureau Veritas UL, CSA, InterTek) should be obtained,verifying the compatibility of the connectors. For more information, refer to https://www.solaredge.com/sites/default/files/optimizer-inputconnector-compatibility.pdf StorEdge Solution with Backup MAN-01-00262-1.5 Chapter 2: Installing the Power Optimizers 23 ATTENTION! Les connecteurs du module doivent être mécaniquement compatibles avec les optimiseurs de puissance. Sinon, le système SolarEdge installé peut être dangereux ou causer des problèmes fonctionnels, tels que les défauts de terre, qui peuvent provoquer un arrêt de l'onduleur. Afin d'assurer la compatibilité mécanique entre les optimiseurs de puissance SolarEdge et les modules auxquels ils sont connectés: Utiliser des connecteurs identiques du même fabricant et du même type aussi bien pour les optimiseurs de puissance que pour les modules. Vérifiez que les connecteurs sont compatibles de la manière suivante: Le fabricant du connecteur doit explicitement vérifier la compatibilité avec le connecteur SolarEdge. Un rapport de test de tierce partie doit être effectué par l'un des laboratoires externes indiqués ci-dessous:(TUV, VDE, Bureau Veritas UL, CSA,Intertek), qui vérifiera la compatibilité des connecteurs. Pour plus d'informations, consultez https://www.solaredge.com/sites/default/files/optimizer-inputconnector-compatibility.pdf IMPORTANT SAFETY FEATURE Modules with SolarEdge power optimizers are safe. They carry only a low safety voltage before the inverter is turned ON. As long as the power optimizers are not connected to the inverter or the inverter is turned OFF, each power optimizer will output a safe voltage of 1V. Package Contents Power optimizers Stainless steel grounding lock washers Installation Guidelines The minimum and maximum string length guidelines are stated in the power optimizer datasheets. Refer to the Designer for string length verification. The Designer is available on the SolarEdge website at https://www.solaredge.com/us/products/installer-tools/designer#/. StorEdge Solution with Backup MAN-01-00262-1.5 24 Installation Guidelines Frame-mounted power optimizers are mounted directly on the module frame , regardless of racking system (rail-less or with rails). For installation of frame-mounted power optimizers, refer to http://www.solaredge.com/sites/default/files/installing_frame_mounted_ power_optimizers.pdf. The power optimizer can be placed in any orientation. If connecting more modules than optimizer inputs in parallel, use a branch cable. Some commercial power optimizer models have a dual input. Position the power optimizer close enough to its module so that their cables can be connected. Make sure to use power optimizers that have the required output conductor length: Do not use extension cables between a module and a power optimizer, between two modules connected to the same optimizer, or between two optimizers other than in the cases specified below. You can use extension cables between power optimizers only from row to row, around obstacles within a row, and from the end of the string to the inverter, as long as the maximum distance is not exceeded. Completely shaded modules may cause their power optimizers to temporarily shut down. This will not affect the performance of the other power optimizers in the string, as long as the minimum number of unshaded power optimizers connected in a string of modules is met. If under typical conditions fewer than the minimum optimizers are connected to unshaded modules, add more optimizers to the string. Equipment grounding tightening torques: 4-6 AWG: 45 lb-in, 8 AWG: 40 lb-in, 10-14 AWG: 35 lb-in. To allow for heat dissipation, maintain a 2.5 cm / 1" clearance distance between the power optimizer and other surfaces, on all sides except the mounting bracket side. StorEdge Solution with Backup MAN-01-00262-1.5 Chapter 2: Installing the Power Optimizers 25 Figure 2: Power optimizer clearance When installing modules in a confined space, for example, if installing Buildingintegrated photovoltaic (BIPV) modules, ventilation measures may be needed to ensure the power optimizers are not be exposed to temperatures outside their specifications. NOTE The images contained herein are for illustrative purposes only and may vary depending on product models. Step 1: Mounting and Grounding the Power Optimizers For each of the power optimizers(1): 1. Determine the power optimizer mounting location and use the power optimizer mounting brackets to attach the power optimizer to the support structure (See Figure 3). It is recommended to mount the power optimizer in a location protected from direct sunlight. For frame-mounted power optimizers follow the instructions supplied with the optimizers, or refer to https://www.solaredge.com/sites/default/files/installing_ frame_mounted_power_optimizers.pdf. 2. If required, mark the mounting hole locations and drill the hole. (1)Not applicable to smart modules. StorEdge Solution with Backup MAN-01-00262-1.5 26 Step 1: Mounting and Grounding the Power Optimizers CAUTION! Drilling vibrations may damage the power optimizer and will void the warranty. Use a torque wrench or an electric drill with adjustable clutch that meets the mounting torque requirements. Do not use impact drivers for mounting the power optimizer. Do not drill through the power optimizer or through the mounting holes. ATTENTION! Les vibrations résultant du perçage peuvent endommager l'optimiseur de puissance et annulera la garantie. Utilisez une clé dynamométrique ou une perceuse électrique avec embrayage adaptable compatible avec les moments indiqués. Ne pas utiliser des tournevis à percussion pour fixer l'optimiseur. Ne pas percer à travers l'optimiseur de puissance ou ses trous de fixation. 3. Attach each power optimizer to the rack using M6 (1/4'') stainless steel bolts, nuts and washers or other appropriate mounting hardware. Apply torque of 9-10 N*m / 6.5-7 lb*ft. For 3NA series power optimizes, SolarEdge recommends mounting the power optimizer on a rail with the smooth side facing out, so that the power optimizer body will prevent its rotation. 4. Use the following methods(1) to ground the power optimizer: WARNING! The metallic enclosure of the power optimizer must be grounded in accordance with the requirements of the local and national codes. AVERTISSEMENT! L'enceinte métallique de l'optimiseur de puissance doit être mise à la terre en accord avec les régulations locales et nationales. (1)These methods have been evaluated by a nationally recognized testing laboratory as part of the optimizer evaluation. The SolarEdge-supplied grounding lug kit has been evaluated only for use with SolarEdge power optimizers. It is not intended or listed to be used as a general purpose grounding lug with other electrical equipment. StorEdge Solution with Backup MAN-01-00262-1.5 Chapter 2: Installing the Power Optimizers 27 For mounting on a grounded metal rail: Use the provided 5/16'' stainless steel grounding star washer between the railing and the flat side of the mounting bracket. The grounding washer should break through the anodize coating of the railing to ensure low resistive connection. Apply a torque of 9.5 N*m / 7 lb*ft. Figure 3: Power optimizer installation and grounding using a star washer For mounting on rails with sliding nut fasteners: If the star washer cannot be used, use the SolarEdge grounding plate (purchased separately) between the railing and the flat side of the mounting bracket. Use mounting specific hardware as needed. Apply torque of 9.5 N*m / 7 lb*ft. See Figure 4. Figure 4: Power optimizer installation and grounding using a grounding plate For mounting on un-grounded structures (such as a wooden structure): If the star washer or the plate cannot be used, use the SolarEdge grounding lug (purchased separately) with an equipment-grounding conductor according to the supplied instructions. The grounding terminal accepts a wire size of 6-14 AWG, and must be sized for equipment grounding per NEC 250.122 requirements. Tighten the screws connecting the power optimizer to the frame and the grounding terminal screw. Apply torque of 9.5 N*m / 7 lb*ft. See Figure 5. StorEdge Solution with Backup MAN-01-00262-1.5 28 Step 2: Connecting a PV Module to a Power Optimizer Figure 5: Power optimizer grounding terminal 5. Verify that each power optimizer is securely attached to the module support structure. 6. Record power optimizer serial numbers and locations, as described in Step 4: Reporting and Monitoring Installation Data on page 53. Step 2: Connecting a PV Module to a Power Optimizer NOTE Images are for illustration purposes only. Refer to the label on the product to identify the plus and minus input and output connectors. For each of the power optimizers: Connect the Plus (+) output connector of the module to the Plus (+) input connector of the power optimizer. Connect the Minus (-) output connector of the module to the Minus (-) input connector of the power optimizer. Figure 6: Power optimizer connectors StorEdge Solution with Backup MAN-01-00262-1.5 Chapter 2: Installing the Power Optimizers 29 Step 3: Connecting Power Optimizers in Strings You can construct parallel strings of unequal length, that is, the number of power optimizers in each string does not have to be the same. The minimum and maximum string lengths are specified in the power optimizer datasheets. Refer to the Designer for string length verification. 1. Connect the Minus (-) output connector of the string's first power optimizer to the Plus (+) output connector of the string's second power optimizer. 2. Connect the rest of the power optimizers in the string in the same manner. WARNING! If using a dual-input power optimizer and some inputs are not used, seal the unused input connectors with the supplied pair of seals. AVERTISSEMENT! Si un optimiseur à double entrées est utilisé et que certaines entrées ne sont pas connectées, fermez ces entrées avec la paire de couvercles fournie. Figure 7: Power optimizers connected in series 3. If you intend to monitor the installation, using the monitoring platform, record the physical location of each power optimizer, as described in Creating Logical and Physical Layout using Installation Information on page 54. Step 4: Verifying Proper Power Optimizer Connection When a module is connected to a power optimizer, the power optimizer outputs a safe voltage of 1V (±0.1V). Therefore, the total string voltage should equal 1V times the number of power optimizers connected in series in the string. For example, if 10 power optimizers are connected in a string, then 10V should be produced. Make sure the PV modules are exposed to sunlight during this process. The power optimizer will only turn ON if the PV module provides at least 2W. StorEdge Solution with Backup MAN-01-00262-1.5 30 Step 4: Verifying Proper Power Optimizer Connection In SolarEdge systems, due to the introduction of poweroptimizers between the PV modules and the inverter, the short circuit current ISC and the open circuit voltage VOC hold different meanings from those in traditional systems. For more information about the SolarEdge system's string voltage and current, refer to the VOC and ISC in SolarEdge Systems Technical Note, available on the SolarEdge website at: https://www.solaredge.com/sites/default/files/isc_and_voc_in_solaredge_sytems_ technical_note.pdf . To verify proper power optimizer connection: Measure the voltage of each string individually before connecting it to the other strings or to the inverter. Verify correct polarity by measuring the string polarity with a voltmeter. Use a voltmeter with at least 0.1V measurement accuracy. NOTE Since the inverter is not yet operating, you may measure the string voltage and verify correct polarity on the DC wires inside the StorEdge Connection Unit. For troubleshooting power optimizer operation problems, refer to Power Optimizer Troubleshooting on page 124.

StorEdge Solution with Backup MAN-01-00262-1.5 114 Configuring StorEdge Applications Configuring StorEdge Applications This section describes the StorEdge applications and how to configure the system. Backup Power Applications The produced power is stored in the battery to be used during power outages. The StorEdge inverter senses the grid voltage, and when it is down it automatically switches to Backup mode, disconnecting from the grid and supplying power to the backed-up loads. This application requires connection to the SolarEdge Auto-transformer and a backed-up loads panel. This application can be used in one of two ways: Backup-only energy stored in the battery is discharged for backup power only, that is, when there is no power from the grid Backup with Smart Energy Management use some of the battery energy for backup power, and the rest for maximize self-consumption(MSC) or charge/ discharge profile programming (for time of use arbitrage) applications. For more information, refer to the StorEdge Applications Connection and Configuration Guide available at http://www.solaredge.com/sites/default/files/storedge_applications_connection_ and_configuration_guide_na.pdf. The Backup application can be used whether or not PV modules are installed at the site. The backup function is disabled by default and can be enabled for on- grid only application, if backup is not needed. System Basic Configuration This section describes: How to enable the Backup Configuration functionality, so that the system can be set up to the available applications (Backup-only or Backup+Smart Energy Management); If Backup Conf is disabled, the system will use the battery energy when PV production is not sufficient in MSC, or when using one of charge/discharge profiles that requires battery discharge.
