I need the wisdom of the group.
I have a 24V 100Ah battery Battleborn LiFePo4 charged by solar 1.1kW. In the summer, I want to run an electric pool vacuum cleaner 180watts. I want to create a low voltage DC disconnect.
I am new to this, and I have no electrical background.
I am thinking I need a low voltage disconnect relay that sends a signal in low amps
OR this one
Then the signal needs to connect to the 120V high amperage AC line black/neutral through this contactor
I am confused, though. One is sending DC current, and the other is expecting AC current. I just want to sense low battery DC voltage and then shut off AC current and stop my vacuum cleaner which will be on a timer.
