Indevolt Batteries UK Support & Info Thread

Mars · 2026-04-04T15:01:25Z

There's some big news for UK solar and home-energy enthusiasts... we’ve just taken delivery of the very first Indevolt Powerflex 2000 Hybrid complete with the PFA 2000 battery expansion pack right here in Britain, ahead of the official summer rollout. This is a true plug-and-play system. It simply plugs into a standard UK 13A wall socket, no complicated wiring, no electrician required. You can even add a cheap smart meter clamp to automatically charge it from excess PV production. The modular expandable design looks like it could finally make home battery storage simple, scalable and genuinely accessible for normal UK homes. I’m gearing up to run full real-world testing and a detailed review over the next few weeks: performance numbers, actual bill savings, backup capability and a complete step-by-step guide on how to install it safely and fully in line with current (and updated) UK regulations. In the meantime, this thread is now open as the dedicated UK support & information hub for the Indevolt battery range. Got questions about: Compatibility with your existing solar setup? UK regs and G99/DNO notifications? Expansion options? Smart integration, app features or anything else? Fire away below! I’ll be sharing my hands-on insights, takeaways and any early findings as I go. Looking forward to your questions so drop them here and let’s get the conversation started! Full video review coming before the end of April 2026. Wow, that is a big YouTube embed!

For a unit that's wired in and has battery sockets that remain live do you also need the grounding rod and changeover. I know you do if you feed power back into the house but I can't make head or tails of the situation if it's wired in and only providing power on sockets in the unit itself.

My UPS (used for my computer and networking equipment) (which is a battery which is charged from the mains and provides output through an inverter only to sockets mounted on the unit) doesnt need that and has no provision for that, neither have other UPS units I have seen.

When the grid is connected to my UPS live is about 230V relative to mains earth and neutral just a few volts, both as expected.

When the grid is disconnected from my UPS both live and neutral register about 115V relative to mains earth. I would probably have expected it to float, so that neither registers any voltage, but it may be that my multimeter has an impedance that is too high for the latter to occur. I suppose I should measure again with a shunt resistor once I have worked out how to do it safely. If it does in fact float (as a bathroom shaver socket with a built in transformer should) then you would need to touch both wires to get a shock; most common faults will not result in shock risk.
