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.
-Normally, the output current of combiner box is larger than 16A.
Thus it can’t be used as the following diagram (Shown as
Figure 4-7
).
M50A is not suitable to connected with PV combiner box.
