Lightning and Surge Suppression

Enphase Microinverters have integral surge protection, greater than most traditional inverters. However, if

the surge has sufficient energy, the protection built into the microinverter can be exceeded, and the

equipment can be damaged. For this reason, Enphase recommends that you protect your system with a

lightning and/or surge suppression device. In addition to having some level of surge suppression, it is also

important to have insurance that protects against lightning and electrical surges. Enphase has tested the

devices in the following tables.
