Installation Guidelines - SolarEdge StorEdge Installation Manual

14 Installation Guidelines
CAUTION!
Installing a SolarEdge system without ensuring compatibility of the model
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
model' 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 models; or
Verify that the connectors are compatible in the following way:
The model connector manufacturer should explicitly verify compatibility
with the SolarEdge 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

The minimum and maximum string length guidelines are stated in 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#/.
Frame-mounted power optimizers are mounted directly on the
module frame, regardless of racking system (rail-less or with rails). For
installation of frame-mounted power optimizers, refer to
http://www.solaredge.com/sites/default/files/installing_frame_
mounted_power_optimizers.pdf.
The power optimizer can be placed in any orientation.
If connecting more modules than optimizer inputs in parallel, use a branch cable.
Some commercial power optimizer models have a dual input.
