SteveC (verified owner) –
Absolutely outstanding bit of kit from an excellent supplier. A replacement for our previous SunWorks controller and worth every penny along with allowing us to add a third panel. This controller “scavenges” more from the panels, especially in low light. I am currently sat in the pouring rain and it’s producing 2amps from 260w panels. We opted for the external display and located the controller out of sight. It’s also connected to our AES fridge and on excess power periods it saves a little gas by operating on 12v direct from the solar.
We are very pleased with this unit. Not cheap but you get what you pay for.
