I would like to connect a system consisting of 12x 670W Panels (2 in series with 6 in parallel) to 3x MPPT 150/100 24V in Parallel, where each charge controller shall have a (2 panels in series with 2 panels in parallel).
Would there be any problem in the configuration as well as the relatively high current?
So you're changing from 2s6p
to 2s2p on one MPPT and using 3 MPPTs?
I dont see any issues assuming you have a sufficiently large battery with high enough C rating to take the peak amps. And of course have sufficiently large bus bars/wires between all devices.
You'd be fine as long as the maximum charging current of your battery bank is not exceeded. If you have a GX device (Cerbo, etc) you can use DVCC to set a maximum charging current and the three MPPTs will be throttled to keep the total under the maximum. If not, you'd need to set the maximum charging current of each MPPT to 1/3 the max for the battery bank. This assumes you don't have other charging sources. If you do, then that current needs to be factored in.
