120V Single-Phase Inverters

120V single-phase inverters suit cabins, RVs, vans, sheds and critical-load circuits that have no 240V appliances. They are simpler and cost less than split-phase units.

Several of these models are stackable. Two matched units in parallel can produce 120/240V split-phase later, so check the "parallel" note on each listing if you might grow.

Buyer tip: A 120V-only inverter cannot run a 240V well pump, dryer or central AC. If you have any 240V loads, shop split-phase instead.
