2000 Wh and up

Effectively portable home backup. Fridge, freezer, well pump, all day.

Effectively portable home backup. 2000 Wh and bigger units run full-fridge-plus-lighting cycles for a day, electric stoves briefly, power tools all day, and can keep a freezer cold through a 24-hour outage. With sufficient solar, this is the class that makes off-grid living plausible. Good fit for whole-house essentials backup, professional location work, RV/boat full-time use, small workshops. What to look for: AC output 2000W+; expandable battery; high surge wattage for motor-start loads (well pumps, deep freezers); a true pure-sine inverter (mandatory — modified-sine kills sensitive electronics); fast UPS-mode switchover if you want unattended backup. These weigh 15–30 kg+, most ship with wheels, and most command a price premium that makes €/Wh comparison brutal. The table below is the easy way to cut through the marketing.
