Compatibility before checkout
Do not choose an expansion battery by capacity alone.
Battery family, voltage, firmware, controls and existing hardware all matter. HEG confirms the match before supply or installation so you know what the system needs.
01
Identify your current equipment
Tell us the controller or inverter model, the existing battery model and how many batteries are already installed.
02
Send labels, serials and clear photos
Include close-up photographs of model labels and serial numbers, plus a wider view of the battery, controls, wiring and available installation space.
03
HEG confirms the correct route
We check battery family, low- or high-voltage architecture, BMS or controller compatibility, cables, switchgear and practical installation requirements before order.
Have your photos ready?
Let HEG check the existing system before you order.
Battery add-on questions
Clear answers before you expand your storage.
Yes. Every card shows the current price of one individual add-on battery, or a clear to-be-confirmed status for a forthcoming product. This page does not recreate the former Uhome two-to-eight-battery price ladder and it does not describe a complete new battery-storage package.
Already have a battery system?
Send us the model details. We will check the right add-on.
Start with your existing battery and controller information. HEG will confirm compatibility, the individual supply-only price and whether you would like the optional £350 installation addition.
