Hello!
I have 1200w 24v solar panels to charge 12v batteries. What mppt solar charge controller i need in between?

24v solar panels to 12v battery
For 1200W at 12V you need 100A.
Use the MPPT calculator to find the correct MPPT for your panels:

The "smallest" MPPT with 100A charging current is the 150/100.
If you can, connect some panels in series to get a higher PV voltage that makes the system more efficient.
