I have an big expensive APC 5000 VA Smart UPS system (online double conversion). Its rated for 3500w of continuous output and it has an internal battery of 960 Volt-Amp-Hours. I can connect up to 10 external battery packs to this system. My idea is to build a grid-assisted system based on this unit. I'd wire everything in the house except washer/electric oven/AC unit into this UPS. The high-consumption appliances and heat-generating appliances would still be on-grid.
With 200w of average continuous consumption, 2 battery packs would get me almost 19 hours of autonomous time. That's plenty of time between charges.
So my question is... how do I generate 220v AC (maximum 30 amps) from a solar panel(s) to charge this big boy? It seems to me like I have 2/3 of a good solar system with this unit (power inverter and battery), so I'd really like to take advantage of it and find a way to charge it using solar panels.
Thanks for everyone's help.
