Chapter 2: Installing the Power Optimizers
Safety
The following notes and warnings apply when installing the SolarEdge Power
Optimizers. Some of the following may not be applicable to smart modules:
WARNING!
When modifying an existing installation, turn OFF the inverter ON/OFF switch,
the Synergy Manager and the AC circuit breaker on the main AC distribution
panel.
CAUTION!
Power Optimizers are IP68/NEMA6P rated. Choose a mounting location where
optimizers will not be submerged in water.
CAUTION!
This unit must be operated according to the operating specifications provided
with the unit.
CAUTION!
Cutting the Power Optimizer input or output cable connector is prohibited and
will void the warranty.
CAUTION!
All PV modules must be connected to a Power Optimizer.
CAUTION!
If you intend to mount the Power 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.
IMPORTANTSAFETYFEATURE
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.
