Guides to selling solar batteries and inverters
Each guide here answers one question an owner has before selling, such as which model is on the wall or what decides a battery's value. They're written from GivEnergy's own documents and from public records, and each one names its sources.

The guides
Model and serial number
Where the labels sit on each unit, and which firmware numbers belong to which generation.
Packs and the inverters they suit
GivEnergy's own pairings, plus the rules for running old and new packs on one inverter.
What a used GivEnergy battery is worth to us
Why two packs of one size can be offered different amounts, and the photos that make our figure more accurate.
Second hand battery value
The things that decide a second hand solar battery's value.
How the guides are written
Figures come from GivEnergy's datasheets and installation manuals. Where two of its documents disagree, we print the datasheet's figure and note what the other document gave.
A few of those documents are copies a distributor hosts rather than the maker. We name them and don't link to them.
Anything about GivEnergy Ltd's administration comes from public records and the administrator's own statement. We report what they said, each with its source, and add no view of our own.
Where we've checked something ourselves, such as how a UK 9.5 kWh battery's serial number reads, the guide says so.
A guide's date is the day we last went back to its sources.
What the guides don't cover
None of them tells you how to repair, reset or rewire a unit. That's work for a qualified installer.
We don't publish a price list, so you won't find figures here either. A guide can explain why one battery is worth more than another, and the offer itself comes by email.
We don't sell kit on this site.
Ask about your own kit
You can send the form without reading a guide first. They help if you want to check the model before you do.
Please don't take it off the wall yourself
A low-voltage GivEnergy pack runs at 51.2 V DC with real fault current behind it. A high-voltage stack runs well above that, and an All in One at around 307 V. Our engineer isolates the system before anything is moved. If your installer has already disconnected it, say so on the form.
