Connection with PV Combiner Box
M50A:
Note for Field Wiring
Due to the limitation of physical wire also the DC connector used in the inverter,
the absolute maximum current of each DC connector should be always observed
as following table to keep fire risk away.
Note that, the following value is provided to identified and checked the justification
for field wiring instead of the DC current rating of inverter.
M50A is not suitable to connected with PV combiner box.
-Normally, the output current of combiner box is larger than 16A.
Thus it can’t be used as the following diagram (Shown as Figure 4-2).
