@Ger The wiring diagram should have been provided by your supplier. The number of MPPT units will depend on the output of each solar panel and how many your have.

Your question is more to do with system design which is not really supported in this forum. Again, you need to get the system designed correctly otherwise you risk damaging the equipment or worse.

'Not really the place for System Design

Long, multifaceted issues involving system design, multiple run on questions with very specific installation and nuanced details are not really well suited for the structure of the community. It is best to have a single question with a clear title per post. More complex enquires are best be directed towards your distributor.'
