Chapter 2: Installing the Power Optimisers

Safety

The following notes and warnings apply when installing the SolarEdge Power
Optimisers. Some of the following may not be applicable to smart modules:
WARNING!
When modifying an existing installation, turn OFF the inverter ON/OFF/P
switch, the DC Safety Unit ON/OFF switch Synergy Manager ON/OFF Switch
and the AC circuit breaker on the main AC distribution panel.
CAUTION!
Power Optimisers are IP68/NEMA6P rated. Choose a mounting location where
optimisers 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 Optimiser input or output cable connector is prohibited and
will void the warranty.
CAUTION!
All PV modules must be connected to a Power Optimiser.
CAUTION!
If you intend to mount the Power Optimisers 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.
IMPORTANT SAFETY FEATURE
Modules with SolarEdge Power Optimisers are safe. They carry only a low safety
voltage before the inverter is turned ON. As long as the Power Optimisers are
not connected to the inverter or the inverter is turned OFF, each Power
Optimiser will output a safe voltage of 1V.
