I have a Multiplus 230V 5000VA that uses my Generator as AC1 Input. I occasionally use my generator to charge my batteries when we get a string of cloudy days. I follow my AC loads quite closely and I notice that when the multiplus accepts AC1 Input, then AC loads shoot up about ~700-1000W
Is there something I'm missing? Is the multiplus using extra AC power to charge my batteries? I separately am able to see the generator power going to the batteries. See screenshot below, generally I am not using more that 400W on AC right now
