Installation Guidelines - SolarEdge StorEdge SE5000-xxS0 series Installation Manual

Installation Guidelines

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. In order to ensure mechanical compatibility of the SolarEdge optimizers
and the modules 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.
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.
Installation Guidelines
The steps in this chapter refer to module add-on power optimizers. For smart modules, start from
l
Step 3: Connecting Power Optimizers in Strings on page 14. Also refer to the documentation supplied
with the smart modules.
The minimum and maximum string length guidelines are stated in the power optimizer datasheets.
l
If connecting more modules than optimizer inputs in parallel , use a branch cable (available from
l
SolarEdge).
Make sure to use optimizers that have the required output cable length. You can use extension cables
l
between rows and from the end of string to the inverter. Extension cables cannot be used between
two power optimizers within a string.
The power optimizer can be placed in any orientation.
l
Position the power optimizer close enough to its module so that their cables can be connected.
l
T o allow for heat dissipation, maintain a 2.5 cm/ 1" clearance distance between the power optimizer
l
and other surfaces.
Refer to the SolarEdge Site Designer for string length verification. The SolarEdge Site Designer is
l
available on the SolarEdge website at http://www.solaredge.com/groups/support/downloads,
under Software Tools.
Completely shaded modules may cause their power optimizers to temporarily shut down. This will
l
not affect the performance of the other power optimizers in the string, as long as the minimum
number of unshaded power optimizers connected in a string of modules is met. If under typical
conditions fewer than the minimum optimizers are connected to unshaded modules, add more
optimizers to the string.
Do not leave the power optimizers connectors disconnected. Open connectors should be mated to
l
each other.
