5.Starting up the controller
4.1 Mounting location requirements
Do not mount the solar charge controller outdoors or in
wet rooms. Do not subject the solar charge controller to
direct sunshine or other sources of heat. Protect the solar
charge controller from dirt and moisture. Mount upright on
the wall on a non-flammable substrate. Maintain a
minimum clearance of 10cm below and around the device
to ensure unhindered air circulation. Mount the solar charge
controller as close as possible to the batteries.
4.2 Fastening the solar charge controller
Mark the position of the solar charge controller fastening
holes on the wall, drill 4 holes and insert dowels, fasten the
solar charge controller to the wall with the cable openings
facing downwards.
4.3 Connection
We strongly recommend connecting a fuse directly to the
battery to protect any short circuit at the battery wiring.
Solar PV modules create current whenever light strikes
them. The current created varies with the light intensity, but
even in the case of low levels of light, full voltage is given
by the modules. So, protect the solar modules from incident
light during installation. Never touch uninsulated cable
ends, use only insulated tools, and make sure that the wire
diameter is in accordance with the solar charge controller’s
expected currents. Connections must always be made in the

battery voltage should between 20V~30V. If the
polarity is correct, the LED on the controller will begin
to show.
2nd step: Connect the solar module
Ensure that the solar module is protected from
incident light. Ensure that the solar module does not
exceed the maximum permissible input current.
Connect the solar module connection cable to the
correct pole of the left pair of terminals on the solar
charge controller (with the solar module symbol).
3rd step: Connect loads
Connect the load cable to the correct pole of the
right pair of terminals on the solar charge controller
(with the lamp symbol). To avoid any voltage on the
wires, first connect the wire to the load, then to the
controller.
4th step: Final work
Fasten all cables with strain relief in the direct vicinity
of the solar charge controller (clearance of
approx.10cm).
