Victron Energy BlueSolar MPPT 100V 30A 12/24V Solar Charge Controller - High Efficiency Solar Panel Regulator for RV, Boat, Off-Grid & Home Power Systems

Victron do make very good solar charge controllers. I do like the victron software however since this isn't the Bluetooth version it requires an adittional cable to connect it. I am having issues trying to update the firmware and the software seems to be erasing any data past 2 days old so for that reason I've dropped a star.Edit: the latest Victron Connect software for Windows 10 has resolved my issues so I've now updated my review to 5 stars.Easy to install, clear instructions. Little dial to set for which battery type you’re charging. Ours is lithium ion and there’s a setting for this. Screws on easily and has three lights showing which phase the charging is in. Had to look up what these mean but very happy with this product. Might go for the Bluetooth version if I ever upgraded but not necessary.Great product, maximizes power from the panels and lets you know exactly what's going on. More expensive than other products but you get what you pay for. You do need a smart phone to download the App and see what is being produced from your panels. Can take an inlet voltage of 100 volts so connect two panels in series and get even more from your solar but make sure you get the right size Victron to deal with the amps. Would definitely recommend.I’m sure the controller is excellent…if I could get one. Victron 100 / 30 ordered and a 75 / 10 arrived. Not the first time judging by other reviews.This is a brilliant piece of kit, the app connects to the dongle allowing different battery configurations / types to be input. User interface is clear with solar status, battery status and charge type... Has historic data (last 30 days) with charge type / duration bulk, absorb & float then the PV watts per day max watts and viltage. Battery voltage min & max excellent
