I like the fact that it will take up to 150 volts input. I was able to series two sets of three panels and only needed 4 conductors and a ground. With lower amperage comes smaller wire, pipe, breakers etc. The display shows all you need to know about what happened today and the previous days. I have the aux. contacts running the transfer switch to connect and disconnect the inverter at programmed voltage settings. It is a quality item that I have no regrets buying.
