Installation Guide

Connecting Multiple PV Array Strings to One Unit
The charge controller has two three-pole PV connectors, allowing up to three PV array
strings to be directly connected in the charge controller. These input connectors can
accept #6 to #14 AWG (13.5 to 2.5 mm
2
) solid or stranded wire.
WARNING
HAZARD OF FIRE
n As per applicable electrical codes, fuses are required when paralleling (combining)
more than two PV strings.
n Fuses must be installed in a combiner box or in a PV array disconnect switch.
n These items are not provided with the charge controller.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
NOTICE
DAMAGE FROM LIGHTNING
To protect the charge controller’s insulation and conductors from damage due to a sudden
over-voltage surge such as a lightning strike, install a DC-rated lightning arrestor on the DC
input line.
Failure to follow these instructions can result in equipment damage.
