I've read most posts with regard to this subject but it is still unclear to me why, given the choice, I should choose VE-Direct instead of VECan or vice versa when connecting my two identical MPPTs to the Cerbo unit.
By that I mean what is the difference between the two protocols, if any, in terms of speed, reliability and efficiency.
Is VE-Can the latest technology introduced or is it the other way around?
I would have thought that, as the name implies, VE-Direct, being hard-wired, would be more practical compared to other serial interfaces.
Any comments, please?
