Chapter 2: Installing the Power Optimizers
Safety
The following notes and warnings apply when installing the p ower 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 Safety Switch 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 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.
CAUTION!
Installing a SolarEdge system without ensuring compatibility of the module connectors with the
optimizer connectors may be unsafe and could cause functionality problems such as ground faults,
resulting in inverter shut down. To ensure mechanical compatibility of the power optimizers' connectors
with the PV modules' connectors to which they are connected:
Use identical connectors from the same manufacturer and of the same type on both the power
l
optimizers and on the modules; or
Verify that the connectors are compatible in the following way:
l
The module connector manufacturer should explicitly verify compatibility with the SolarEdge
o
optimizer connector; and
A third-party test report by one of the listed external labs (TUV, VDE, Bureau Veritas UL, CSA,
o
InterTek) should be obtained, verifying the compatibility of the connectors.
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.
