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.
Residential
Commercial
• Citel DS72-RS-120 surge protector; data sheet
• Delta LA-302 lightning arrestor; website
• Midnite solar surge protection device MNSPD-300 or
MNSPD-300FM (with flush mount box); website
• Citel DS73-RS-G surge protector; data sheet
• Delta LA-303 lightning arrestor; website
NOTE: Protection against lightning and resulting voltage surge must be in accordance with
local standards.
