I have a 5.3kva generator, Multiplus 48/5000, 3 x Pylontech us3000c batteries. I have had to use the Weak AC option to use my generator. When the generator is on and charging the batteries, my battery is getting around 2350watts, my generator is producing around 2650watts and my AC loads keep flunctuating. When I turn a light on it flickers, is it best to not use appliances and lights when the generator is on? It’s frustrating because I want to be able to use everything in my cabin while the generator is on.
