Best polystring setup for H3-Pro-15.0
Posted: Sun Nov 09, 2025 7:20 am
Hello,
on my roof there are two options I can think off possible for setting up a polystring on one MPPT (PV1+PV2).
1. use 7+7, same orientation -65° (ESE) but different angle of the roof 15° and 38°
or
2. use 4+4, different orientation -65° (ESE) and orientation 115° (WNW), but same angle of the roof 15°
Which options should I best take? If both are "working" as polystring at same MPPT, I would prefer the 7+7 as to get more power with the higher amount of panels. Even this might be less efficient.
What do you think?
