Whole home backup with Enpower as service entrance and PV combiner connected to Enpower. This is the preferred configuration for back up of the entire main load panel. This configuration supports up to an 80A breaker for the PV circuit and an 80A breaker for battery storage. - Page 8 PV combiner circuit is more than 80A. In this configuration, the PV combiner circuit connection space in Enpower is left vacant. When existing PV combiner circuits are connected to the main load panel, and you want to add battery storage to the system, you can keep the PV combiner connected to the main load panel and connect only the battery storage system to Enpower.

Page 14: Step 4: Install Breakers As Needed
Enpower smart switch installation and operation Step 4: Install Breakers as Needed The Enpower includes one two-pole 40A circuit breaker that feeds the neutral forming transformer (NFT). You can install additional breakers, if needed. You must follow all NEC and local electrical codes. - Page 15 L. Use the M4 screw (from the lit kit marked 150-00148 that ships with the Enpower) to secure the mains breaker (not the load breaker). Use a T20 drive to tighten the M4 screw to 1.5 N•m (13.3 lb•in). Do not use any other screw.
- Page 16 Required practices when torquing connections: • Always follow NEC 2017 110.4 (D) dictates. • You must use a calibrated torque tool to achieve the indicated torque values. • Use tamper-proof torque mark/paint after torquing connections. © 2020 Enphase Energy Inc.
