sum of all PV module's ISC. The ISC of the PV array must not exceed the controller's
maximum PV input current.
Please refer to the table as below:
CAUTION: When the PV modules connected in series, the total voltage must
not exceed the max. PV open circuit voltage 92V (MSC**10N1), or 138V
(MSC**15N1) at 25℃ environment temperature.
Battery wire size
The battery and load wire size must conform to the rated charge current, the
reference size as below:
CAUTION: The wire size is only for reference. If there is a long distance
between the PV array and the controller or between the controller and the
battery, larger wires shall be used to reduce the voltage drop and improve the
system performance.
CAUTION: For the battery, the recommended wire will be selected according
to the conditions that its terminals are not connected to any additional
inverter.
