For permitted 48 V off-grid or backup homes that need listed split-phase power and room to stack more units later.

A low-cost split-phase inverter-charger for an off-grid home that may add units later. Strong charger and parallel support, but no safety listing.

For a 48 V off-grid home or backup system that needs 120/240 V from a single listed inverter-charger.

A budget low-frequency split-phase inverter-charger for an off-grid cabin with a 240 V generator. It handles heavy loads, but documentation is thin and it cannot be stacked.

A budget low-frequency split-phase inverter-charger for an off-grid cabin with a 240 V generator. It handles heavy loads, but documentation is thin and it cannot be stacked.

For a large off-grid or backup home on 48 V that needs a listed, single-box 12 kW split-phase inverter-charger at a lower price than premium brands.

For an off-grid home or cabin that wants 120/240 V split phase from a 48 V bank for the lowest price. Expect to accept a short warranty and no verified listing.

For an off-grid or backup home on 48 V that needs a listed split-phase inverter-charger with heavy surge at a lower price than Outback or Schneider.

For a small off-grid home that needs 120/240 V split phase from a 48 V bank on a tight budget, fed by a 240 V generator. Larger homes should step up to the 6 kW.
