I swapped it out after seeing the you tube video and have ended up buying a second one for my other pilot vehicle
Five stars for delivery and condition of item.I need to use this item to charge my recent purchase of a 50Amp ATEM battery I purchased from you.I would like to submit a review when satisfied with their operation!
Good unit and works well
There were no instructions supplied with this unit, so I had no idea had to change modes to work with a Lithium battery. The Mode push-button was not doing anything. When I tried to call Vic Off-Road for help, all I got was an automated message. I didn't have internet access, cos we were away camping, so I had no way of using their online help either. Fortunately another camper nearby had a similar MPPT solar controller from a different manufacturer (they looked identical, just a different colour) and he showed me how to change modes. Turns out, you need to hold the mode switch down for over 5 seconds. Would it be that hard to put that key piece of information on the actual controller?!?!?
Great product, fast delivery, good value
Good compact mppt controller and suits my lithium battery setup
