Victron is a quality product . it works as it should. So far no problems. Wish I could say the same for the inverter I bought . Be VERY CAREFUL when buying inverters. They are often sold as American grid tie but they are European grid tie. Not compatible. That is why I bought the transformer. To create a split phase. Problem is the 230 volt inverters still output at 50hz. NOT USA 60hz. Mostly problem for motors.
