Circuit to shut off inverter at low battery voltage set point = 50%

Relay will bounce unless close voltage is set higher. Here is what happens: 1. Voltage goes down to low set point = 12.06 ~ 50% 2. Relay opens, no load on batteries, now voltage goes above 12.06 3. Relay closes, which places load on batteries, now voltage goes below 12.06 4. Go back to step 2. repeat process ( relay now is in circular cycle )
