Hi all
I have 2 Charge controllers
1. Victron Energy SmartSolar MPPT 75V 15 amp 12/24
2. Victron Energy SmartSolar MPPT 100V 20 amp 12/24-V
Do need to connect them to charge one battery.
What will be the best way to wire these controllers without buying some additional buck up solution?
Connect them both directly to the battery
It is never a good idea to use a battery as a busbar, that is sloppy wiring and opens you to issues.
A good source of info is the wiring guide https://www.victronenergy.com/upload/documents/The_Wiring_Unlimited_book/43562-Wiring_Unlimited-pdf-en.pdf
Connect them via a bus bar and be sure to independently fuse the connections.
You will want to use smart networking, unless you have a GX, to help coordinate charging.
This is all documented in the relevant manuals.
