I am planning to use a SmartSolar MPPT 150/70 Tr VE.CAN as the primary charger for my battery bank (4 × Pylontech RT12100G31 = 400 Ah total).

To increase the total charging current, I am considering adding a Skylla IP65 12/70 (1+1).

Can these two chargers be used in parallel to charge the same battery bank?

If it is possible, should I connect them via VE.CAN for synchronization, or should they operate independently?

Thank you!!

Yes they can be used in parallel, provided the voltage settings are correct. However, you will need a GX device to interpret the CVL from the Pylontech and communicate that to the MPPT and iSkylla units.
