Deciding Backup Circuits

A.

We recommend subpanels and require them if you have Arc-Fault / GFI breakers

B.

Ensure you keep the inverter within its amperage limits

•

ON-Grid = 50A Continuous (pass-through)

•

OFF-Grid = 37.5A Continuous | 67A Peak (10s) | 104A Peak (100ms)

C.

Verify each load circuit by measuring typical and max Amps with a clip-on Amp meter. Amps x 120V = Watts

D.

Install a subpanel for backup loads if you have Arc-Fault / GFI breakers, NOT a multi-circuit transfer switch
