How long will it last?
As a rough guide, if about 80% of the capacity is usable, 5.3 kWh runs a 1 kW load (lights, fridge, TV, Wi-Fi and a few plugs) for around 4.2 hours, or a 2 kW load for around 2.1 hours. Check the usable depth of discharge on the datasheet; we can send it with your quote.
Before you order
- Match the battery voltage to the inverter: most home inverters take 48 V low-voltage batteries; larger three-phase units often need high-voltage stacks.
- Confirm the inverter and battery can communicate (CAN or RS485) so charging is managed properly. We check this on every quote.
- Plan for growth: if you may add capacity later, buy a model you can parallel or stack.
- Mount it indoors or in a ventilated, shaded enclosure, and have it installed by a registered electrician.
Covered by the manufacturer’s warranty, on top of your rights under the Consumer Protection Act. Prices include 15% VAT.
Pair it with an inverter from our inverter range, or get it matched for you in a back-up package.
