Chapter 2: Installing the Power Optimizers Chapter 2: Installing the Power Optimizers Safety The following notes and warnings apply when installing the power optimizers: WARNING! When modifying an existing installation, turn OFF the inverter ON/OFF switch, the AC/DC Safety Switch and the AC switch of the distribution panel. Avant de faire ces étapes, éteignez l'onduleur monophasé en mettant sur OFF l'interrupteur ON/OFF situé au bas de l'onduleur.
Chapter 2: Installing the Power Optimizers Afin d'assurer la compatibilité mécanique entre les optimiseurs de puissance SolarEdge et les modules auxquels ils sont connectés, il faut : 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.
Chapter 2: Installing the Power Optimizers Step 1, Mounting and Grounding the Power Optimizers 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 4). For optimizers supplied with module frame-specific brackets, attach the power optimizer to the module frame following the instructions included with the optimizers. 2 If required, mark the mounting holes locations and drill the holes.
Chapter 2: Installing the Power Optimizers For mounting on rails with sliding nut fasteners, or an un-grounded structure (such as a wooden structure): Connect an equipment-grounding conductor to the grounding terminal according to the instructions supplied with the grounding terminals (grounding terminal kits are available from SolarEdge). The grounding terminal accepts a wire size of 6-14 AWG, and must be sized for equipment grounding per NEC 250.122 requirements.
Chapter 2: Installing the Power Optimizers Step 2, Connecting a Module to a Power Optimizer 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.
Chapter 2: Installing the Power Optimizers 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 optimizers' datasheets. Refer to the SolarEdge Site Designer for string length verification. NOTE: String length should not exceed 300m from DC+ to DC- of the inverter. Use at least 11 AWG/ 4 mm² DC cables.
Chapter 2: Installing the Power Optimizers In SolarEdge systems, due to the introduction of power optimizers 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 systems’ string voltage and current, refer to the VOC and ISC in SolarEdge Systems Technical Note, available on the SolarEdge website at http://www.solaredge.
Chapter 3: Installing the Inverter Chapter 3: Installing the Inverter Install the inverter either before or after the modules and power optimizers have been installed. NOTE: For single-phase inverters, use only copper conductors rated for a minimum of 75°C. For three-phase inverters, use only copper conductors rated for a minimum of 90°C. For three-phase inverters where opposite polarity DC conductors are routed in the same conduit, 1000V rated cables must be used.
