Do you have timer which can switch power from 12 v battery bank via an inverter to 120 v AC lighting load
Previously we used a timer operated by 12v DC battery bank to switch the 120 v AC inverter output. Timers which we have inserted between the inverter and load do not keep proper time. It would seem that switching between the battery bank and inverter would require switching over 20 amps. Switching the 120 v AC inverter output 210 watts of only 2 amps. The inverter does not have sleep mode so we do not know why the clock portion of timer does not work. Is there a battery powered (Displqy and Switch) device which can switch the inverter ?
