GivEnergy All in One (Gen 1), AC-coupled

By Daan Haket · researched and written with an AI assistant · updated 26 October 2026

Gen 1 is the AC-coupled All in One. It has different power and warranty figures from the All in One 2, even where the stated storage figure looks the same.

Research from manufacturer documents, not a hands-on test. Values and missing details are kept separate below.

What matters on your quote

For an existing solar installation, confirm the AC connection and Gateway separately. Do not carry the Gen 2 warranty or expansion promises onto a Gen 1 quote.

• The stated warranty duration is not a complete account of registration, throughput or service conditions.
• The manufacturer product page was rechecked on 26 October 2026. This review confirms the product claims; it does not independently establish every condition in the full UK warranty.

At a glance

Not in the documents we checked so far: round-trip efficiency, warranty throughput / cycles, capacity at end of warranty, expandable to, UK list price.

Ask the installer before you sign

• Is the usable capacity on the quote the figure above, or a nominal one?
• Can it charge fast enough to fill in your cheap window? Charging power × hours of the window is the most it can take in.
• Is any equipment needed for backup in a power cut included in the price?
• Does it work alongside your current solar inverter, or replace it?
• Which warranty conditions apply in the UK, and what do you have to do to keep them?

Will it pay back for you?
