Merged Europe and APAC and NAM to a single document.

This technical note specifies inter-compatibility between various models of the S-Series and P-Series SolarEdge power optimizers, as well as the inter-compatibility of the P-Series power

optimizers with previous series of power optimizers (PBxxx and OPxxx).

The term “inter-compatibility” refers exclusively to the installation of power optimizers in the same PV string.

When replacing a power optimizer, the replacement power optimizer does not need to be identical to the replaced power optimizer, but it must be compatible with the other power

optimizers in the string.

NOTE

Installing different series and models of power optimizers in the same installation is allowed as long as they are installed in separate PV strings. However, power optimizers that are

inter-compatible may be installed in the same PV string.

NOTE

When replacing a power optimizer always verify with the SolarEdge Designer that the power, current and voltage specifications of the PV module are compatible with the

replacement power optimizer specifications. Ensure that the module Voc (at minimum ambient temperature) does not exceed the replacement power optimizer’s maximum input

voltage. Use the SolarEdge Designer to quickly validate electrical compatibility.

Refer to the power optimizer datasheet for details.

Version 10.0, December 2021 2 The following compatibility tables detail the Power Optimizer series and models that can be installed in the same PV string, during installation or in case a power optimizer is being replaced. If a cell does not contain a check mark, the relevant power optimizers cannot be installed in the same string.
