Disabling LV alarm
Is there a way to disable the low voltage alarm buzzer on the circuit board in a pure sine wave inverter? Some manufacturers set the voltage alarm too high. The one I have starts buzzing at 11 volts. I want to disable the buzzer but not the shut-off function. Any advice is appreciated.
12.2 vdc open circuit is a nearly dead battery to start with.
If you have done the math correct, I assume your comment about a 1.5 kWH battery means a 125 AH, 12v battery. Maybe two Walmart Everstart MAXX-29 series.
Alarms on inverters are usually set for 10.5-11 vdc.
For that sized inverter, depending on total wire length, should be using at least #4 wire, preferred #2 wire.
