I have a CPAP machine for sleep apnea and I'm trying to find a solution (not to expensive) to have a backup for 6 to 8 hours in case of a power failure.
My machine draws 200 Watts.
The fact that UPC for this would be way to expensive, someone suggested a 12 volts Sealed Lead acid battery (but did not tell me how many amps I should get), a 300 watts inverter and a DPDT relay. Anyone knows if this would work, if so, can you help me choosing these equipments. how many amps my battery should have, is a 300 watts inverter enough, what kind of DPDT I should get and how do I plug this all together to make it work.Any other suggestion would be appreciated.
Thank you.
