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#/.
Chapter 2: Installing the Power Optimizer 19 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 steps in this chapter refer to module add-on power optimizers. For smart modules, start from Step 3: Connecting Power Optimizers in Strings on page 24.
20 Installation Guidelines P860 and M1600 power optimizers Figure 3: 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. Three Phase System Installation Guide MAN-01-00527-1.
Chapter 2: Installing the Power Optimizer 21 Step 1: Mounting and Grounding the Power Optimizers (1) For each of 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). It is recommended to mount the power optimizer in a location protected from direct sunlight.
22 Step 1: Mounting and Grounding the Power Optimizers (1) 4. Use the following methods 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.
