Installation Manual

Installing the Enphase S-Series Microinverters
and Engage Cable
QUICK INSTALL GUIDE
®
The Enphase S-Series Microinverter (S280-60-LL and S230-60-LL) meets the requirements of NEC 690.35.
Enphase Microinverters do not require that you install a GEC between microinverters because the DC circuit is isolated and
insulated from ground.
Ground fault protection (GFP) is integrated into the microinverter. To support integrated GFP, use only PV modules equipped
with DC cables labeled PV Wire or PV Cable.
To monitor solar production you must install an Envoy-S. Refer to the Envoy-S Installation and Operation Manual or Quick Install
Guide
