PiS & Battery Question(s)
I am currently looking into the benefits of PiS (and hopefully a battery) for my house, but I am not clear on what the best solution would be for my needs or whether my preferred connection approach would even work.
I have two Consumer Units in the house. One covers the whole house (inc. Utility w/WM + TD) except the Kitchen/ Diner/ Family Space. The second covers the Kitchen/ Diner/ Family Space and has a feed going to the shed (10mm2 armoured, 36A breaker). The Whole House CU also has an 'empty' 36A breaker that used to feed the shed.
For various reasons I cannot look at roof mounted solar for the foreseeable future.
Ideally I would like to put panels on the roof of the shed (c.20ft long, 5ft wide) that feeds a battery that then plugs into the shed CU (I have a spare way, so could put a single socket on that).
The other option is to utilise the 'empty' 36A breaker on the whole house CU. This is on a 10mm2 wire as well. I can extend this down to the shed. A bit more work, but doable.
Ultimately I'd like the panels on the roof of the shed so they can be there all year. I'd also like the battery in there so it isn't in the house.
With either of these options, my thinking is that the power would then flow back from the shed to the CU in the house and get used.
Does it work like this? I might be getting it all completely wrong.
Any thoughts or advice would be very much appreciated. Cheers.
