STEP 9:
Once the batteries and solar panels
are all connected and wired to the Large
Green Connector, Disconnect PV+ wire and
plug the connector to the MPPT Solar Control-
ler until the connector latches click into place.
The Battery Charging LED should light up for
about 60 seconds. Now connect PV+ to the
green connector.
Warning:
Battery should always be con-
nected first and disconnected last from
the controller.
STEP 10:
Plug the temperature sensor to the Temp Sensor input on
the MPPT Solar Controller. Refer to the TPDIN

manual for setup and operation of the MPPT Solar Controller.
STEP 11:
The vent fan is capable of running at 24 or 48V. Connect to
the controller Aux output or directly to the batteries.
STEP 12:
Tighten the cable glands on the wires to make weatherproof
connections. Plug unused holes using the supplied hole plugs. To plug
an unused cable gland, cut a short piece of wire, insert into the cable
gland and tighten. If desired, attach the enclosure to the solar mount
pole using chain or cable for security.
STEP 13:
You may want to put a fine screen over the vent holes on
either end of the enclosure to keep out insects. Window screen works
well. Be sure to secure all cables so they won
’
t move in the wind. All
cable connectors will be protected by being located under the solar
panels.
