I currently have the following:
10 KVa 48v Quattro with two old BlueSolar 150/85 MPPT's and a Venus controller running ESS with gel batteries. The MPPT's are connected to the venus via Ve.can bus. When I remove the terminator on the venus and plug the type b cable from the batteries the MPPT's is no longer visible. It seems that there is no write up running the old type bluesolars MPPT's with Polyntech.
