One or two SCC's

[TT's]

I have 4-310 watt panels on my rv, total 1240 watts. These could be in 2s2p configuration with 150/100 SCC or 2- 100/50 SCC with panels in series. Do you think 2 will give better results? I am thinking about using Victron for SCC.

If you’ll ever be dealing with any shading issues, that’s a reason to prefer 2MPPTs over one.

If you’ll never have to with shading, results will be similar do it comes down to cost versus redundancy...
