Hi guys,
I want to know if there is someone that have send in there old Microcare MPPT for an upgrade to use lithium batteries? I'm looking for n picture inside the MPPT to see what modifications Microcare do on the hardware, apart from the firmware upgrade they also do? They will mostly want to add the power protection board that the old MPPTs dont have, the 4 pin plug that communicates with the BMS and the big question what else for the 4 wires on the plug? Is it worth it?
