Charge Controller to Battery Wiring
Connect the charge controller to the battery using 10 feet (or less) of 6-AWG, 90
o
C copper
wire. The shorter the wire run, the better. This is due to the voltage drop that occurs in the
wires when the device is charging. When connecting the charge controller to the battery,
ensure there is a 50-amp fuse between the charge controller and the battery on the positive
side, as shown in Figures 5 and 7 below. Place the fuse as close to the battery as possible.
Battery Fusing
Examples of fuses to use are a terminal fuse block, manual resetting breaker or an ANL type
fuse. A 50-amp fuse is recommended for all installations.
Automatic resetting breakers are NOT recommended.
Temperature Sensor
The CINDER 40 comes with a 10-foot temperature sensor that has a ring terminal on one end
and two exposed leads on the other end. If using a lead acid battery,
connect the
temperature sensor leads to the charge controller’s TEMP terminals. Note that there is no
polarity with this connection.
Once tight, give each lead a light tug to ensure that they are
properly connected. Then, tape the ring terminal side of the temperature sensor to the side
or the top of your battery. This is recommended over connecting it to one of the battery
terminals because it will give a better gauge of the actual temperature of your battery. It is
important to use the temperature sensor as described to accurately charge your lead acid
battery bank over all temperature ranges. Do not use the temperature sensor for lithium
batteries. (See the
for information on temperature behavior during charging).
12-Volt and 24-Volt Load
Connect your 12-Volt DC circuits to the load terminal to enable remote control and
monitoring of these devices. Please see the
for a full load description,
examples and load wiring recommendations.
