SAM Solar Inverters without Transformer SMA PV OFFSET BOX

Certain kinds of PV modules are subject to power degradation when exposed to negative voltage to ground (polarization). The PV Offset Box maintains the performance capability of these modules even if they have inverters that cannot be grounded. If the degradation has already started, the device helps to regenerate the modules. The PV Offset Box is designed for inverters up to 1,000 V. Operation with all PV array components (PV modules, cables, inverters) has to be released by the respective manufacturer.
