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.
