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
