I have two quattro 8kVA's in parallel set to export excess PV to grid. This is all DC-coupled PV.
This works well, but I'd like to confirm the limitations of the system.
I intend to expand the system.
1.) Is the combined export to grid capability of the quattro's 16 kW or 6.5kW x2 = 13 kW at present?
2.) Observing the 1:1 rule, if I add 16kW of PV inverter capability on the quattros' output is the new export capability now 1.) plus 16kW?
