STEP 8:
Attach the green DIN Rail clips
to the MPPT controller bracket using
screws provided and attach the bracket to
the controller. The extra parts aren
’
t used.
Remove the small plate on the controller
bottom to access the wire terminal
screws. Connect the battery wires and the wires from the PowerVent
™
fan to the controller battery input. Be sure to observe proper polarity.
(RED=+).
CAUTION:
Reverse polarity connections will damage the equip-
ment.
STEP 9:
Connect the included solar panel cable to the MPPT controller
PV inputs (Red to PV+). Don
’
t connect the solar cable to solar panel
connectors until the controller is con-
nected to the batteries.
STEP 10:
Connect your load to the
MPPT Controller load output. When the
MPPT controller is energized with full
battery voltage the load will turn on
automatically.
STEP 11:
Replace the wire terminal
access door on the back of the MPPT
controller and mount the MPPT control-
ler to the DIN rail mounted on the en-
closure door.
STEP 12:
Double check wiring and
then re
-
install the battery cable fuse to energize the system. The MPPT
controller will power up and automatically detect the battery configura-
tion. The display is activated by vibration, so to turn on the display, tap
the glass cover. Once the controller is energized, connect the solar
panel connectors to the solar cable coming from the MPPT controller.
CAUTION:
Reverse polarity connections will damage the equip-
ment.
Important Note:
The MPPT Controller ships with AUTO detection
of battery voltage enabled.
We suggest changing this to a fixed 24V,
if using a 24V battery configuration, so that the system can recov-
er automatically if, by chance, the batteries get drained complete-
ly
. See MPPT controller user manual for specific instructions.
STEP 13:
Make sure lid gasket is clean and free from any particles,
then carefully close the cover, making sure that wires are clear of the
seam and hinge area. Use your own lock to secure the door.
