Power Backup

Sizing an inverter and battery for your home

Choosing a backup power system starts with a simple question: what do you need to keep running when the power goes off? For many households the list includes lights, Wi-Fi, TV, the fridge, security systems and phone charging. Heavy loads such as geysers, ovens and kettles are usually best left off a battery system because they drain it quickly.

We add up the power your essential appliances use and how many hours of backup you want, then recommend an inverter and battery size to suit. If you plan to add solar panels later, choosing a compatible inverter now saves money. Installation should always be done by a qualified electrician and include a certificate of compliance.
