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

The legal situation is that anything connected to the house electrical system needs to be an approved device, and must be not be connected to a circuit also carrying loads. RCD must be bidirectional and the circuit breaker should switch both L and N.

Lower end powerstations have very limited solar input (and cr.p solar panels when bought as a package) so getting 1800W in from four panels will only work with the bigger wattage powerstations, ie the more expensive ones. Separate components and battery are another route to go and actually cheaper though not so convenient if you need to lug them around. Fast falling battery prices make it an interesting proposition, though.

Even at that time, it was not the legal situation in England and Wales. And Ecoflow knew it wasn't, which is why in the UK their inverters are supplied with a hard-wire adapter and the instruction that it needs to be wired into a dedicated breaker at the consumer unit. I don't know where thay YouTuber got their info, but it's wrong.

Can I install the STREAM Microinverter myself?
The system can be installed and maintained by users themselves. However, if you are in the UK, due to local regulations, the BKW DIY cable used with the Stream Microinverter must be connected to the distribution board. This operation requires a professional installer or electrician.

After much researching, my decision came down to something I hadn't thought of.... weight.
I can lift a 25kg bag of potatoes, but it is no fun.  I can comfortable lift 12.5kg.  So anything I am taking when I go away, I need to be able to lift in.  So I have decided to go for a powerstation that is about 1000wh.  I'm glad I got that sorted in time for the Black Friday sales.
On other matters, I am still intrigued by saving money in the house.  I have moved towards the idea of having some solar panels in the garden to go with a battery set up, but I still do not want to feed into the grid.  I was thinking about 4 x 400 watt solar panels, but they are taller than me and weigh about 25 kgs.  I have also looked at planning permission and the panels have to be 5 metres away from the boundaries, I don't think I have that in my garden.
I am also going to have a chat with an electrician about a switch, so I can go from grid power to battery power.
I have spent a lot of time watching YouTube videos.  I have been looking at Will Prowse, solar channel and I am intrigued by the idea of building a solar system with a 48v battery and all in one inverter.
I have also started to use my 300w powerstation as a charging station in the house for tablet, phone and rechargable lights, after Will Prowse information on how to maintain and use LiFepo4 batteries.  I haven't been doing mine any favours, leaving it unused for months.
Thank you everyone for your thoughts and suggestions.

This all sounds like an interesting project and I'd love to hear how you get on, but I suspect you're not going to save any money.
