Very satisfied with the ProStar 30 Controller. Simple set up and design, well built to survive life on a boat. Just need to upgrade my solar panels. Can recommend this device to fellow sailors. The interaction with the shop’s team was very smooth

Works awesome! I had been using the Prostar 15 for years at a solar powered radio site. Not a single flaw in all these years. There was a need for upgrade, so ProStar 30 was my obvious choice. For those who wanna use this controller for a 2 way radio, rest assured it does not generate any interference

Can I set the charge voltage manually via a computer?
06/14/2021, 11:28
The device automatically determines the right voltage. It can be either 12 or 24 V.
Does it support two independent battery banks?

No, this model can be used with one battery bank only or with multiple connected in parallel.
