this is my oil furnace battery back up , plus one outlet , it is a aimes hard wired 12v 1200 watt inverter with built in transfer switch
, a home built battery 200ah lifepo4 with a overkill bms , not having to add other meters to see what was going made install much cleaner , the blue tooth to my tablet works great .
battery has circuit breaker in box and is attached to inverte2 with a 175 amp anderson connector and #2 wire
this is a small system only ment to run the furnace untill i decide to start the generator , larger transfer switch on left is for that , the 12v is in line after main transfer switch , so 12v goes off gen goes on
as for charging thats a project for later , for now i use a small noco charger that does lifep4 only took me watching 100 for Will's videos to try something
below is a shot of the furnace running at 229 ways but it does go up to 497 when all zones are working , in this pic it was just heating my hot water after being off for a day , when the furnace is doing nothing it pull 23 watts
house is very well insulated and does not cool down fast , but if the power goes out over night or i am away i hoping this will get few more hours of heat i am hoping for a least 8 hrs but and will test out on a cold day at some point maybe i will ad a solar panel or two
now be kind if you see something wrong
