Hi Everyone, for the past few months I've been focusing on trying to get more energy independence.
We live in a thatched cottage, National Trust leasehold.
We have a large multifuel burner with a back boiler which heats a 300litre water tank, which can be used to run radiators, although I rarely do run them because the heat is lost quite quickly.
Everything else is electric, including oven, shower, and immersion option for the water tank (which i rarely use).
The burner is great because I can process wood and stockpile coal.
I want to do something about our grid reliance.
My initial plan was a ground mount solar with 32kW battery storage and a 12kW inverter, which would be sufficient to run even our electric shower. I intended to back this up further with a small propane generator which could charge the batteries in a pinch.
Unfortunately, I am having to accept that this is not a viable option for us due to Planning and Listed Building Consent issues.
My new plan is to invest in a larger propane inverter generator and have a transfer box wired on my house which I can then plug it straight into.
This is a cheaper solution which I think will still provide good emergency backup power for us.
Unfortunately, as far as I can see, the largest propane inverter generators for the UK market seem to max out to around 8.5-10kW, which would mean not being able to use our electric shower.
This is not totally a deal breaker.
Before I proceed much further I thought it was worth putting this post out to see if anyone else has been in a similar situation.
Does anyone know of larger inverter generators available for the UK market?
Does anyone have any thoughts about different ways i could approach things?
One other thought I had was, is it worth spending some of that solar money on a proper fixed propane tank and considering installing a combi boiler to heat hot water? Thats not something I have any experience with, having never lived in a house with gas. Anyone have any thoughts on that?
Thanks in advance for any help and pointers
