MC4 dual source switch either a or b
I have a 800 watt solar panel array that feeds to my solar water pump. I would like to add a switch to be able to chose either the solar array to power the water pump or an ac to dc inverter powered with a generator to pump when I don't have enough sun. Currently I'm manually unplugging the mc4 connectors and plugging into the other source as needed. I would like to find a switch with to choose either source a or b. Any ideas if they are available. I have also thought about just adding it with a y connector but I'm afraid it could back feed the solar array and cause damage or lose of current.
