Mobile all-in-one unit with inverter built in

What 20kWh actually covers

As a rough guide: a household running lights, fans, fridge, router and general sockets typically draws 0.5–1kW continuously, so this unit carries that kind of load for the better part of a day. Add air conditioning and the figure drops sharply — a single split unit can draw 1–1.5kW on its own.

The 11kW output matters separately from the 20kWh of storage: output decides what you can run at once, storage decides for how long. Tell us both what has to run and for how long, and we will confirm whether this is the right unit.

Suited to

  • Whole-home backup where outages are long enough that a small UPS is not enough
  • Solar self-consumption — storing daytime surplus for evening use
  • Premises where switching between grid and battery has to be automatic
