I ordered this unit for my trailer to charge 3 deep cycle batteries. So far no complaints, works as a charm. Mine is the model with a display, it shows the actual system voltage. I can see it from across the room in the dark. That's a very nice feature, so I recommend the ones with a display

I’m very pleased with the performance, it is a great controller. The hookup couldn’t be easier. The LCD displays correct values for Solar Current, Battery Voltage, and Load Current. Handles all types of batteries. Charging modes include Boost, PWM Regulation, Equalize, and Float. Highly recommend the store and the product

I plan to put this in my garage and the temps fall to -20 sometimes, will the LCD handle this?
