Hello,
I'm a bit lost with contactors and their variety.
I have a small solar setup. The solar charger has a programmable load output of battery voltage, which I want to use as a power for a changeover switch. When the batteries are in good charge state, I want mains power to be powered from the batteries>inverter>AC. But when the batteries discharge would reach pre-set voltage level, the load output from solar charger goes off and I want a changeover switch to swap into mains power.
The batteries nominal is 24V, the mains is 240V / 16A AC. Is there a simple way to wire two contactors as a changeover switch, with 24v dc control? When I google for contactor wirings, it leads me to industrial applications, with way too much details for my head.
Any advice much appreciated.
Thanks
