Lightning And Surge Suppression - enphase Q 7 Micro Installation And Operation Manual

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.
• Citel DS72-RS-120 surge protector;
• Delta LA-302 lightning arrestor;
• Midnite solar surge protection device MNSPD-300 or
MNSPD-300FM (with flush mount box);
NOTE: Protection against lightning and resulting voltage surge must be in accordance with
local standards.
