We have been building our off grid retirement home for 8 years and now it's time for power.
The home is build is completely out of concrete (too many wild fires and no fire response).
The build has been done by yours truly, two of my employees, wife and my 3 sons mainly on weekends and holidays........
Flat work and roof pour I hired out, I know my limitations.
Exterior walls, interior feature walls, roof and roof overhangs, slabs and suspended slabs all concrete.
Almost all interior framing is reclaimed wood as are all beams. Loft framing is all reclaimed as are the 3x6 t&g floor boards.
Located on an Island in BC, Canada that is off grid, and is boat access only.
We are now almost fully insulated,walls will be R32, R62 roof slab R24 with no thermal bridging.
Used all triple glazed glass which was all wet glazed.
So far the home performs well, during the summer heat dome in BC the indoor temp never went over 24C =75F while outdoor was 122 F for over a week. Winter indoor hasn't gone below 10C = 50C.
Need to get power now into our house. Please help me decide.
Have been reading and reading for over the last 9 months and have decided on 48V and want it to be as reliable as possible.
The inverters for the 48 volt system that I'm leaning to are
1. SMA 6048 x 2 $ 8000 CDN
2. Victron Quatro 5000 x 2 $ 6000 CDN
3. Sigineer 15kw. $ 4100 CDN plus import duty.
The batteries that I'm interested in are the EV Tesla S. This allows for easy expansion. Would like to end up with 40kw.
BMS would use the EVTV is probably the one to get.
We have installed a Scotty microhydro station, and last year purchased 32 x 320w panels that will be part ground mound and
partly on our seacan. The PV panels aren't installed yet. The pic below is sort of what I want to do to mount them.
We do have a mini PV set up of 8 x 75w that has kept or fridge running for the last 10 years.
Lots of work ahead but need to get things ordered as the supply chain issues makes deliveries take for ever.
A few pics of our build.
Thanks for reading.
