I added a inverter to my RV to run my 110 appliances from my battery bank. To avoid having to unplug the generator feed and plug in the inverter every time I wish to feed the circuit breaker in the rv I installed a relay. The normally closed position on the relay routes power from the inverter to the circuit breaker. The normally open contacts route power from the generator to the circuit breaker. The relay coil is 120vac and gets power from the generator with a time delay.
So operation goes like so.
1. generator is off and inverter is powering the circuit breakers.
2. I start the generator which begins a 30 second delay to allow the generator to stabilize
3. after 30 seconds power is applied to the relay coil and the relay closes and now the generator output is feeding the circuit breakers.
4. I turn off the generator so the coil loses power and it returns to its normally closed position which connects the inverter to the circuit breaker.
The whole thing works like a charm EXCEPT when I turn off the generator and it winds down the relay chatters and this killed the inverter.
I tried a cap across the coil to no avail.
I put a EMI filter before the relay coil and it helps but still too much chatter.
Is there a way to clamp the coil voltage so when the generator drops to lets say 100vac the relay opens.
Thanks for any input.
