I'm very happy with this 5000VA 48V power inverter. I live off grid and my old inverter was having trouble starting my water pump if anything else was running, especially the microwave. We can now run everything as we used to - even the dishwasher. It charges the batteries well from the generator when we need. Installation and setup was easy, and it seems simple enough if I want to increase the charging current - I've left as default for now. I've had it installed now for 2 weeks and really can't fault it.
