I have a 110V two cycle generator I use for camping and I want to turn it off remotely at night without going out in the cold and hitting the kill button. I bought a 12vdc RF wireless Remote Control relay switch to use to short the coil and kill the generator engine and a small 12vdc transformer to provide the 12vdc power.
The problem is that when I trigger the remote kill, the remote relay locks closed and the generator starts to die, but so does the 110VAC, and subsequently the 12Vdc, and then the remote relay loses power, opens, and the generator continues running. I need a temporary power supply which will keep the remote relay working for 15 - 30 seconds after the 110 VAC is killed. I could simply hook up a battery, but the generator sits for months without running and the battery would be dead every time I try to use it.
I also do not want to carry around a big 12 volt battery for only such a small task. I am thinking there might be a way to use a capacitor as a temporary power supply. The generator runs for hours prior to killing it at night so there is plenty of time to charge a capacitor. I also guess I could get a small rechargeable 12 VDC battery (the relay will supposedly run off a A23 Battery), like for a remote garage door opener, and simply charge it up every time, but charging and completely discharge those batteries is not suppose to be good practice. Any suggestions on a solution?
The 12Vdc remote relay I have can be found on Amazon as "
O'plaza ®Dc 12V 10A Relay RF Wireless Remote Control Receiver Momentary Switch (12V 1 Channel)", but I have no idea how much current it draws.
