in case your wondering
when you set the limit, it sets the max the magnum will alow to be used from the source, so the batteries are charging, and you turn on the a/c etc..
when it hits 23 amps source input, it reduces charge power used to keep the load at 23amps or less
it partial prevention of input power shore/generator overload
don't know what it will do if you turn on two high draw items that exceeds input power
that might be PT's load/voltage support, where the inverter function comes on and you start using battery power along with the 120v input power
