reverse polarity connections, but the charge controller will not function until the battery is connected properly.
A 40 amp fuse needs to be placed in the positive wire connecting the charge controller to the battery.
2) Connect the Solar Panel (PV) Array
Insert the solar panel wiring to the SOLAR terminals on the front of the charge controller and tighten the
terminals from the top of the controller using a screwdriver to ensure a good connection is made. Be sure to
note the polarity of each terminal; the charge controller self-protection feature will prevent damage from
reverse polarity connections, but the charge controller will not function until the PV Array is connected
properly.
A 40 amp fuse needs to be placed in the positive wire connecting the charge controller to the solar
panel(s).
WARNING: High voltages may be present on the solar panel output wiring. Solar panels produce electricity
when exposed to light. Make sure the solar panels are placed in the shade and are NOT in direct sunlight.
Use caution and avoid touching any conductors in the system circuit to avoid electric shock.
3) Connect the Load (Optional)
This step is optional and only required if you want to power a small (less than 30A) DC load through the
charge controller. Connect the wires from the appliance to the LOAD terminals on the front of the charge
controller and tighten the terminals from the top of the controller using a screwdriver to ensure a good
connection is made. Be sure to note the polarity of each terminal; the charge controller self-protection feature
will prevent damage from reverse polarity connections, but the charge controller will not function until the
load is connected properly.
A 40 amp fuse needs to be placed in the positive wire connecting the charge
controller to the load.
4) Connect the Battery Temperature Sensor – BTS (Optional)
The charge voltage required by batteries changes with battery temperature. Temperature compensation of
the charge voltage enhances battery performance and life, and decreases battery maintenance. Automatic
temperature compensation can be provided through use of the optional battery temperature sensor
(included). The Temperature compensation is -4.0 mV/Cell/
o C.
1) Plug the provided BTS cable into the socket labeled “BTS” located on the left side of the controller as
shown below.
2) Connect the ring terminal on the BTS directly to the negative battery stud, or use an adhesive to
attach the sensor to any side of the battery to be monitored, below the electrolyte level as shown
below. Mounting the sensor directly on the battery stud is more reliable against vibration and will
provide a good thermal connection to the battery as well. It is best to place the sensor between
batteries and place the batteries in an insulated box to reduce the influence of the ambient
temperature outside the battery enclosure.
