Dragonfly is supplied with 50 AMP 240V AC. It goes to three fuse panels and 12 -120V outlets. It runs 4 A/C units, refrigeration, ice maker, charger, microwave,  hot water heater ( underway hot water comes from the engine) and whatever we have connected to the 120V outlets.

When not connected to shore power the Northern Lights diesel generator supplies the 120V

When neither shore power nor the generator is working the Heart Inverter 2500 supplies the 120V. The inverter gets its power from either the 4-8D batteries or, if the engine is running, from the oversized (150AMPS each) alternators.
