Whole Home Backup / 400 A Meter-Main
- 2 PWRcell Inverter - 2 CT Kit (incl.)
- 6 PV Links - 2 200 A PWRcell ATS
- 2 PWRcell Battery - 4 SMMs
This design shows two PWRcell systems, each connected to a PWRcell ATS for whole
home backup. This system configuration will provide backup power to essential loads
split between two sub-panels fed by meter-main combination equipment. This solution
also applies to designs with seperate meter and service panel equipment. Utilize
Generac load management as needed in accordance with NEC 702.4(B) and Article
220. If preferred, non-essential loads can be left in the meter-main where they will not
be powered during a utility service interruption. This design is acceptable for most
residential 400 A 120 V / 240 V services.
