13 Installation Guidelines
CAUTION!
Installing a SolarEdge system without ensuring compatibility of the module
connectors with the Power Optimiser connectors may be unsafe and could
cause functionality problems such as ground faults, resulting in inverter shut
down. To ensure mechanical compatibility of the SolarEdge Power Optimisers'
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 Optimisers and on the modules; or
Verify that the connectors are compatible in the following way:
The module connector manufacturer should explicitly verify compatibility
with the SolarEdge Power Optimiser connector; and the Inverter DC input
connectors.
A third-party test report by one of the listed external labs (TUV, VDE, Bureau
Veritas UL, CSA, InterTek) should be obtained, verifying the compatibility of
the connectors.

Installation Guidelines

For the minimum and maximum number of Power Optimisers in a string (string
length), see the Power Optimiser datasheets. Refer to the Designer for string length
verification. The Designer is available on the SolarEdge website at: .
Do not use extension cables between a module and a Power Optimiser, between
two modules connected to the same Power Optimiser, or between two Power
Optimisers other than in the following cases:
Between a Power Optimiser and a module:
Extension cables of up to 1.8 m are allowed for all Power Optimisers (0.9 m for
DC+, and 0.9 m for DC -).
P-Series Power Optimisers with the 4-type suffix in their part number (Pxxx-
4xxxxxx) and the Mxxxx-Series - extension cables of up to 16 m can be installed
per Power Optimiser (8 m for DC+, and 8 m for DC-).
Between two Power Optimisers or between a Power Optimiser and the inverter:
Extension cables can be installed between Power Optimisers only from row to
row, around obstacles or pathways within a row and from the end of the string
to the inverter. The total length of the extension cables may not exceed the
following values:
