Can I use the MiniBoostPRO inside my engine bay? BMPRO Customer Support December 13, 2021 04:28 The MiniBoostPRO cannot be used inside an engine bay as it is rated to IP20. Related articles What happens if my solar system produces more solar than the maximum solar input on the BatteryPlus35-II? At what point will the MiniBoostPRO begin solar charging? Does the MiniBoostPRO connect to home solar panels? My RVMaster Controller is displaying the code 88 and is unusable. What can I do? If I have both a BatteryPlus35-II and a MiniBoostPRO, both products will have solar inputs. Which one will become the dominant solar input device?
