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!

Keeping the electrical circuitry complexities aside, I wonder whether such small battery storage systems can be used in niche usecases. For example, when you run the dehumidifier to dry clothes indoors, and that consumed about 1 to 1.5 kWh a day. If you can keep one such battery in the utility room, charge from off-peak and later run the dehumidifier on an off-grid mode using the AC sockets in the battery.

From my experience, these type of usage may not be the simplest to manage. I am thinking schedules for charging, etc. Some niche cases may work if it could be slotted under kitchen cupboards using all the spare space, maybe running all the appliances from them?

A quick cross read of this thread made me think much of it sounds very simple, too simple? How could the battery/inverter system island unless it is disconnected from the grid? Or is this using a manual switch (and how does it cope when you switch back)? Clearly no such system is powerful enough to supply 100A to your neighbours on top of your own...

And as for running it in a wet room, let's not forget the advantage of getting "renewable fireworks"? 😆

How could the battery/inverter system island unless it is disconnected from the grid?

I suppose that you could be instructed manually to switch the main switch on the CU. But how could it tell the difference between this and the absence of grid which by regulation requires cut out. There could, I suppose be a manual changeover switch on the unit itself, so to island while connected to house infrastructure you need to flick the main switch on the CU and a switch on the unit itself.

For me personally that would be perfectly acceptable, but I cant see it would satisfy the regulators or the DNO! Im therefore currently sceptical about the claim that it does islanding!

@batpred I assume you plugin the battery on a wall socket, charge, then unplug and run the dehumidifier as if it's a portable battery that you take with for camping.

I would definitely not be running wires underneath cupboards in the kitchen. Like you say, don't want renewable fireworks!! I was thinking more like charge from a socket in the utility room on the countertop (set a schedule on the app etc), then run the dehumidifier from the battery AC sockets after unplugging the battery from the wall socket. I assume it's same as running the dehumidifier from a wall socket.
