The PIDbox of iLumen regenerates PID affected solar panels and preserves them from future loss of efficiency. This device was developed in a way that it works independently of the inverter and therefore it can never harm. 

An exception to this rule is the PIDbox Light, a slightly modified version of the PIDbox mini, which is easy to install but is not uncoupled from the inverter when it is active.

A test of ABB/Power-One Italy S.p.A shows that the PIDbox Light is compatible with the following list of transformer-less string inverters (Fig. 2).

In its report, ABB further declares that by following the installation and operation instructions of the inverter and the PIDbox Light, the combined operation of both devices will not adversely affect the inverter operation and will not affect the inverter standard warranty.
