Because maybe there will be several methods of connecting solar pa
Tie Inverter, different connecting method maybe should use different model inverter. In this
case, there are two connecting methods.
With method 1, because all panels are connected in parallel, so we can know that the
TVoc(total Voc of the solar panels) will be same as Voc of one panel, and the TVmp also
is same as Vmp of one panel. So we can get the specifications of the solar panels array
with solar panels connected each other.
TPmax:245W×4 TVmp:29.4V
TImp:8.34A×4 TVoc:36.9V
TIsc:8.68A×4
cause, the DC input
voltage range of this model is 22V to 60V, so the TVoc and TVmp is in the DC input voltage
range
With method 2, we also can get the specifications of the solar panels array.
TPmax:245W×4 TVmp:29.4V×2
TImp:8.34A×2 TVoc:36.9V×2
TIsc:8.68A×2
ecause, the DC
input voltage range of this model is 45V to 90V, so the TVoc and TVmp is in the DC input
voltage range.
The two connecting method diagrams are shown in Fig.4 and Fig.5 below.
