Ordered for my husband's project to make a solar powered golf cart. It was easy to mount on the underside of the solar panels which serve as the golf cart's top. Just what we needed for project.

Just a quick update in the sunsmart 5000 watt inverter. It has worked perfectly and I think it's better than my eg4 3000 watt. Works flawlessly and is easy to use.
