Installation Guidelines

For the minimum and maximum number of Power Optimizers in a PV string (PV
string length), see the Power Optimizer datasheets. Refer to the Designer for PV
string length verification. The Designer is available on the SolarEdge website at:
https://www.solaredge.com/us/products/installer-tools/designer#/.
SolarEdge allows the use of extension cables on the input side of the Power
Optimizer when connected to a PV module or between two modules as long as:
The total length of the round-trip cable, modules, and Power Optimizer input
cables, do not exceed 16 m.
The connectors of the extension cables are identical to the connectors of the
Power Optimizer.
The Power Optimizer can be placed in any orientation.
Position the Power Optimizer close enough to its module so that their cables can be
connected and fastened to the mounting structure.
Make sure to use Power Optimizers that have the required output and input
conductor length.
Completely shaded modules may cause their Power Optimizers to temporarily shut
down. This will not affect the performance of the other Power Optimizers in the PV
string, if the minimum number of unshaded Power Optimizers connected in a PV
string of modules is met. If under typical conditions fewer than the minimum Power
Optimizers are connected to unshaded modules, add more Power Optimizers to the
PV string.
To allow for heat dissipation, maintain the following clearance (see Figure 8 ):
