Hey, not a clue what section this would go in so mods please move if need-be,
Basically Im looking at making my own uninteruptable power supply using deep cycle 12v batteries. Ive got an idea on the main of how the system would work however im abit unsure of calculations i may have if someone could confirm what im saying is true;
I need to produce about 300w (230v AC so 1.3Amps?) to last 4hours
so at 12v its (300w/12 = 25amps), so in total i would need 25amps x 4 hours = 100amp hours battery wise
so to produce 1.3amps 230VAC i would need one 12v 100Ah battery?
Obviously efficiency ratings haven't been calculated such as the inverter efficiency etc
Any help would be great
