Hi everyone... Maybe my Google search skills are poor, so please feel free to point me to another thread...
I want to have DIY battery backup in the basement for the fridge and lights, which are on a different floor. The electricity is sent up to the floor via a subpanel with a breaker that connects to the main service and a breaker that then sends 220 two phase up to the floor.
I'm thinking to get a nice LiFePO4 battery or two and add a breaker to this subpanel that is connected to a 110v inlet box attached to this new breaker. (Since this is only for fridge and some lights, I will only need a single phase inverter and can use the leg that powers the fridge on the upper floor.)
As it is, the system is pretty DIY, and if power goes out, I would have to go downstairs and turn off the breaker that goes to the main (so I dont backfeed the grid) and then plug the inverter into the inlet.
As of now I'm just considering an inverter charger that can be left in charge mode most of the time and can also charge batteries via genset.
Does anyone know how I could make this process automatic? So with the desired setup above: 1) automatically switch from charge to inverter mode and 2) automatically anti-island?
Thanks!!!
P.S. - I might also want to keep the hallway lights running which are on a different subpanel in the basement. I assume I can put a second inlet near the hallway lights subpanel and run the same setup just with a power strip from the inverter feeding the two inlets? Just checking if there could possibly be any ground-fault problems with this...?
