Tell us what you run — or just your ECG bill — and we'll size the inverter, battery and panels you likely need, then see realistic price, savings and payback ranges before an engineer confirms the design.

Add what you want to run. We've filled in typical wattages and running hours — change any of them if you know better. Example: 10 lights at 15W for 5 hours.

Running air conditioners? They are deliberately left out of the starting list — an AC can easily double the system you need, so we only size for one if you tell us to.

Use the figures from your latest ECG bill or prepaid top-ups. Give us either one — the units (kWh) are more accurate if you have them.

Add items likely to run together, especially ACs, pumps and heaters.

W

Only the lights and equipment you want powered during an outage.

A bill shows energy use, but it cannot reveal your peak load. If you leave the load fields blank, the calculator scales a preliminary outage load from your consumption instead of using a fixed minimum. An engineer must still confirm it.

Lowest cost covers normal daily energy. Balanced also restores the energy used during your selected outage. Maximum backup plans to refill the whole usable battery in one sunny day.

This mainly affects the full-battery-recovery design.
