I have a home made backup sump pump solution consisting of an AC powered sump pump plugged into a 750W inverter which is powered by a 12v deep cycle marine battery.
I also have a 13.8V 25A DC power supply. If I connect the power supply to the battery in parallel, will the power supply power my sump pump as long as the power isn't out (then if the power goes out will the battery power the sump pump)?
Also, if I leave the power supply plugged in, will it keep the battery charged or will it overcharge?
I hooked everything up as explained above and measured the voltage to be between 13.77 and 13.82V which seems to be in a safe range.
Any advice would be appreciated.
Thanks,
Dan
