I need some help with the above bit of kit. Have searched the net and believe they are now upgraded to the 6000. The instructions I have are in German and cant make head nor tail of em. I know its some sort of charge regulator that was used on yachts and boats so am hoping the yachters amongst you can give me some idea how it works. I could do with English instructions, but am thinking that's a tall order. I think its somehow connected via a shunt into the battery's and inverter, but that's only a stab in the dark. Any help would be much appreciated as we want to be able to connect the self seeking solar tracker to it if possible.
