Is anyone using a powerstation as a home battery for savings with Economy 7?

There was someone a few years ago(2021 maybe?) who fitted a storage battery to his all-electric E7 flat, for much the same reason. I thought his idea had merit but (with electricity and battery prices as they were then) he was looking at a 7-8 year payback and the anti's were scathing.

We then had the energy price spike that we're still in the tail of. I suspect he will have broken even by now.

Anyway, back to your question. You might want to take a look at the EcoFlow Stream range of plugin storage batteries.

I've been to look at the Ecoflow Stream.  I still don't understand what it is, but it is not a straightforward powerstation.  I watched a YouTube video were someone connected one up and their electricity meter was going backwards.  Although, they didn't explain, I can now see why it needs to be wired in by an electrician.

That looks like a larger battery bank intended for use with solar power.  Though battery banks can also be configured to charge at night on cheap rate electricity, instead of solar power.  Not the sort of thing you should be installing yourself.

If it is installed with solar, you will need permission from your DNO (District Network Operator).

In the UK, your meter should never go into reverse.  If it does, you're supposed to tell your electricity company so they can swap it for a new one.  These days, that will be a smart meter.
