Off-Grid Solar Inverters

An off-grid inverter runs a home or cabin entirely from batteries and solar with no utility connection. It handles the full load on its own, so sizing and surge capability matter far more than they do on a grid-tied system.

How to Choose

Size to your largest simultaneous load, then check surge. A well pump or compressor can draw three to five times its running current at startup, and an inverter that cannot deliver that surge will trip no matter how large the battery. Split-phase 120/240V is standard for a US home; 120V-only units suit cabins and RVs. Confirm the charge controller's PV input window matches your array voltage.

Key Specifications Explained

  • Continuous output: 3kW to 12kW typical, split phase 120/240V
  • Surge capability: Look for 2x continuous for several seconds
  • Battery voltage: 48V dominates modern systems; 12V and 24V for small builds
  • Solar input: Integrated MPPT on all-in-one units — check max PV voltage and current
  • Stacking: Many units parallel for more power or split-phase output

Frequently Asked Questions

What size inverter do I need?

Add your largest simultaneous loads, then confirm the surge rating covers motor startup. Most homes land between 6kW and 12kW.

Can I add solar later?

Yes with an all-in-one that has integrated MPPT. Size the inverter for the array you eventually want, not the one you start with.

Split phase or 120V only?

Split phase 120/240V for a house with a well pump, dryer or range. 120V only is fine for cabins and RVs.
