Backup power

Keep the lights on. Choose which ones.

A lithium battery charged by your panels keeps your home running when the grid doesn’t. The question is what you want it to carry.

Most homes

The essentials

  • Lights
  • Wifi and router
  • TV and decoder
  • Fridge and freezer
  • Gate motor and alarm
  • Phone and laptop charging

Leave off: Kettle, oven, geyser, pool pump

A separate essentials circuit keeps a modest battery going for an evening outage and beyond.

Working from home, bigger households

The whole house

  • Everything on the essentials list
  • Kettle, microwave and oven
  • Washing machine
  • Air conditioning, within reason

Leave off: Geyser on battery power (run it on solar in the day instead)

Needs a bigger inverter and battery. The estimate shows honestly whether the extra cost is worth it for your house.

Why lithium iron phosphate

  • Safer chemistry. LiFePO₄ is far less prone to overheating than older lithium types, which matters for a battery on your garage wall.
  • Built for daily use. Rated for thousands of charge cycles, so it can charge from solar every day, not just during outages.
  • No maintenance. No topping up and no fumes, unlike the lead-acid batteries a lot of first-generation backup systems used.

See how long your battery would last.
