I'm thinking about building battery backup using 300 ah lifepo4 battery using 16 to build a 48v system. Want to get a mppt to charge and invert to prefer 220vac but to run a couple refrigerators and a window AC and a few lights in the house all 110vac devices. would like to know how long it will run pulling a 4kw v contuse load?
Thanks for any input.
