1Your Electricity Usage
Electricity only, including the standing charge. We'll work out the right battery size and show you what your bill becomes.
The kWh figure on your monthly bill or in your energy app. If your bill covers a different period, divide by the number of days and multiply by 30 — e.g. 1,050 kWh over 90 days ≈ 350 kWh a month.
Electricity only, including the standing charge, for a full 12 months — your energy supplier's annual statement shows this.
The “annual consumption” or “estimated annual usage” figure on your bill or annual statement.
Your electricity rates
p/kWh
p/kWh
If your bill shows more than one rate, use the average: usage charge in pounds ÷ kWh used × 100 (e.g. £100 ÷ 400 kWh × 100 = 25p). No overnight tariff yet? Leave 7p — it's an example of what an overnight tariff can offer, not a guaranteed rate.

Dimensions and weights are taken from the manufacturer datasheets for the DX Series all-in-one ESS, the DX EB-1608 battery cabinet and DX-S Series hybrid inverter, the ASW5120-LB-G3 battery module and the ASW H-S2 / SH hybrid inverters — all downloadable from our Resources page. Wall-mounted items are drawn at an indicative mounting height; the final height is set by your installer on the day. Floor loading, ventilation, clearances and cable routes are confirmed during the free survey.
