IMPORTANT SAFETY INSTRUCTIONS 13 IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS WARNING! The inverter cover must be opened only after switching the inverter ON/OFF switch located at the bottom of the inverter to OFF. This disables the DC voltage inside the inverter. Wait five minutes before opening the cover. Otherwise, there is a risk of electric shock from energy stored in the capacitors. - Page 15 NOTE A SolarEdge inverter may be installed in a site with a generator. SolarEdge requires installing a physical or electronic interlock, which will signal to the inverter when the grid has been disconnected. Interlock procurement, installation, maintenance and support are the responsibility of the installer.

Page 20: Installation Guidelines
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. - Page 21 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 23.
- Page 22 Chapter 2: Installing the Power Optimizer 21 Make sure to use power optimizers that have the required output conductor length. 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.
-
Page 23: Step 1: Mounting The Power Optimizers
. 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. CAUTION! Drilling vibrations may damage the power optimizer and will void the warranty. -
Page 24: Step 3: Connecting Power Optimizers In Strings
Chapter 2: Installing the Power Optimizer 23 Connect the Minus (-) output connector of the module to the Minus (-) input connector of the power optimizer. Figure 6: Power optimizer connectors 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. -
Page 25: Step 4: Verifying Proper Power Optimizer Connection
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. In SolarEdge systems, due to the introduction of power optimizers between the PV modules and the inverter, the short circuit current I and the open circuit voltage V hold different meanings from those in traditional systems. -
Page 26: Chapter 3: Installing The Inverter
Identifying the Inverter Refer to the sticker on the inverter that specifies its Serial Number and its Electrical Ratings. Provide the serial number when contacting SolarEdge support. The serial number is also required when opening a new site in the monitoring platform. - Page 27 - a lifting aid. CAUTION! SolarEdge inverters and power optimizers can be installed at a minimum distance of 50 m/ 164 ft from the shoreline of an ocean or other saline environment, as long as there are no direct salt water splashes on the inverter or power optimizer.

See Circuit Breaker Criteria table below for standard sizes suitable for SolarEdge three phase inverters. NOTE If the result has a decimal fraction smaller than 0.5 round it down.
