I have a AC300 with one battery pack and three Solar modules.
Due to sunlight and some blocking houses i want to split them and restart with twice two panels (one will be loading with morning to midday light - the second with midday to afternoon light).
They will be connected via to separated strings which can be directly connected to the AC300.
Question: Do I need two Battery Packs to load via two (2) PV Strings? Or can I connect them as I did before?
@claus80 AC300 supports two MPPTs and can be connected to two sets of solar panels. One solar panel can be connected to one B300.
However, three solar panels cannot be connected in parallel, but only separately and individually.
So I guess this is the documentation in the manual:
8.2.1. Charging Method 3: Solar Panels (via 4pin aviation-MC4 cable)
● For regular solar panels:
The AC300+B300 supports two PV inputs. Each individual input supports up to
12A and the charging voltage should be between 12-150V. The AC300+B300
can achieve a combined maximum of 2400W of total solar input.
a. User can connect solar panels in series(Figure 1).
b. Connect the MC4 port of solar panels to the MC4-Aviation cable (Figure2/3).
c. Plug the Aviation cable to the middle input port on AC300.(Figure 4)
