Security
The following notes and warnings apply when installing power optimizers:
WARNING !
When modifying an existing installation, turn the ON / OFF switch of the inverter and the AC circuit breaker on the main switchboard CA.
WARNING !
The input and output connectors are not waterproof until mating. Open connectors must be connected to another connector or be sealed with
waterproof caps.
WARNING :
This unit must be operated within the operating specifications in this document.
WARNING :
Cut the connector of the input cable or output of the power optimizer is prohibited and void the warranty.
WARNING :
The power optimizers comply with IP65 / NEMA4 standard. Choose a mounting location where optimizers will not be immersed in water.
WARNING :
If you intend to mount optimizers directly on the module or module frame, first consult the module manufacturer for instructions regarding the
mounting location and, where applicable, the impact on the module warranty . Drilling holes in the module frame can be done according to the
instructions of the module manufacturer.
WARNING :
The installation of SolarEdge system without ensuring compatibility module connectors with Optimizer connectors may be dangerous and could
cause functionality problems as defects of grounding, resulting in switching the inverter.
To ensure mechanical compatibility of the SolarEdge optimizers and modules they are connected:
• •
Use identical connectors from the same manufacturer and the same type for both the power and the modules optimizer; or
• •
Make sure the connectors are compatible as follows:
▪
The connector manufacturer should explicitly verify compatibility with the SolarEdge connector optimizer; and
▪
A third test report from one of the following external laboratories (TUV, VDE, Bureau Veritas UL, CSA, Intertek) must be obtained
regarding the verification of the compatibility of connectors.
SECURITY ELEMENT IMPORTANT:
The modules with SolarEdge power optimizers are safe. They have only a low safety voltage before the inverter is switched on. As power optimizers
are not connected to the inverter or the inverter is in the OFF position, each power optimizer will output a safe 1V voltage.
