I am curious about stacking SSC
My experience so far has been this
Originally I had a Victron 100/50 with a pair of 300 watt bi facial mono panels in series... it would pump as much as 55 amps into the batteries yeah, more than the rated power output of the panels... (when conditions are right)
Then I added an EPEver 40a MPPT with 3x 200w mono panels in series
The pair of these would pump a little south of 100 amps into the batteries
Then I added three(3) EpEver 60 amps SCC, each with 3x, 250w Santan Solar panels, However I rarely see more than 35a on these controllers... in addition, the other controllers are now quite limited I rarely see more than 170a coming off the collection of SCCs... I rarely see more than 2500w coming in... BUT the overall daily power production is hugely increased...
If you are keeping track, I have 3450w worth of solar panels... and 270a of potential charging capabilities
I SHOULD be able to hit as much as 250a on peaks with these panels...
I was able to make some adjustments to the SCC settings that helped quite a bit...
Would it make more sense to swap out these units for LARGER controllers such as 100a or 120a? I get it, my primary limitations here is the 12v system... I COULD convert to 24, or even 48v, its a thought
