Deciding Backup Circuits

A. Ensure you keep the inverter within its amperage limits

• ON-Grid = 200A Continuous (pass-through)

• OFF-Grid = 12kW = 50A Continuous (62.5A w/ solar) | 24kW = 100A Peak (10s) | 30kW = 125A Peak (100ms)

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

C. Install a subpanel for backup loads if there is a chance of exceeding any amperage limits while powering the

entire home off-grid, failure to do so will result in outage and potential damage to the inverter (see pg. 12).

D. If you have Arc-Fault / GFI breakers, DO NOT use a multi-circuit transfer switch.
