The battery wire size must
conform to the rated current, the
reference size as below:

NOTE: The wire size is only
for reference. If there is a long
distance between the controller
and the battery, larger wires can
be used to reduce the voltage drop
and improve performance.
Installation
1. Connect the solar panel and
battery to the solar charger
mounting bracket.
• Loosen the positive (+) and
negative (-) terminal screws of
the solar ports.
• Feed the solar cables into the
ports. Red wire to positive (+),
black wire to negative (-).
• Tighten the screws until
secured. The torque force for
the screw should be 25lbs-inch
for 10AWG wire, 30lbs-inch for
8AWG wire, and 35lbs-inch for
6AWG wire.
• Repeat the steps above to
connect the battery to the solar
charger mounting bracket.
NOTE:
• A DC fuse must be installed in
the positive wire between the
solar input and the mounting
bracket solar port.
A DC fuse must be installed
in the positive wire between
the battery and the mounting
bracket 25A/50A port.
The rating of the fuse is
determined by the maximum
input rating of the solar panel,
or output of the controller.
• A DC disconnect switch must
be installed between the
solar input and the mounting
bracket solar port.
A DC disconnect switch must
be installed between the
battery and the mounting
bracket 25A/50A port.
The rating of the switch is
determined by the maximum
input rating of the solar panel,
or output of the controller.
• Base on the current of the
MPPT charger you purchased,
connect the battery to the
corresponding 25A/50A
charging port.
NOTE: The battery was
supposed to be connected to
50A port and could operate
normally with both 25A & 50A
MPPT charger if pre-installed
by RV factory.

2. Choose an appropriate
mounting position and attach
the solar charger mounting
bracket on the wall using four
self-tapping screws.
3. For better ventilation, keep the
MPPT charger away from any
obstructions:
Top: 17"
Left and Right Sides: 8"
