Installation Guidelines - SolarEdge Se K Series Installation Manual

CAUTION!
Installing a SolarEdge system without ensuring compatibility of the module
connectors with the Power 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 SolarEdge 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 Optimizers 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 Optimizer connector; and
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 Optimizers in a string (string
length), see the Power Optimizer datasheets. Refer to the Designer for string length
verification. The Designer is available on the SolarEdge website at:
https://www.solaredge.com/products/installer-tools/designer#/.
Do not use extension cables between a module and a Power Optimizer, between
two modules connected to the same Power Optimizer, or between two Power
Optimizers other than in the following cases:
Between a Power Optimizer and a module:
Residential Power Optimizers P300-P601 - extension cables up to 0.90 m can be
installed per Power Optimizer (0.90 m for DC+ and 0.90 m for DC -).
Power Optimizers with the 4-type suffix in their part number (Pxxx-4xxxxxx) -
extension cables of up to 16 m can be installed per Power Optimizer (8 m for
DC+ and 8 m for DC-).
Power Optimizers manufactured starting from working week 42, 2019, as
indicated in the serial number (Example: S/N SJ5019A-xxxxxxxx - working week
50, 2019) - extension cables of up to 16 m can be installed per Power Optimizer
(8 m for DC+ and 8 m for DC-).
