NOTE: To ensure good vehicle chassis ground connections:
• remove all paint, grease, debris at grounding point.
• use sandpaper/emery cloth to expose chassis bare metal.
• use ring terminal and star- or lock-washer to secure cable.
• dielectric grease can be used to minimize corrosion.
Before proceeding, mount the solar module(s) per the manufacturer’s
instructions. If adding batteries that are not factory installed, they
should be safely secured in their desired location. The SunSaver Duo
should be mounted per the instructions in section
Mounting
.
Step 1: Ground SunSaver Duo
Ground a negative terminal of the SunSaver Duo to the vehicle
chassis. The SunSaver Duo has a common negative; it does not matter
which negative terminal is grounded. Use wire with black insulation,
appropriately sized for the system charging current (see page 17).
Step 2: Battery #1 (“house” battery bank)
Connect Battery #1 to the SunSaver Duo as shown in figure 4. In RV
installations, Battery #1 should be the “house” or cabin battery.
If the cabin battery was factory installed, battery negative should
already be grounded to the vehicle chassis. Use a short piece of black
wire to ground the cabin battery if necessary. Use red wire for battery
positive. Use wire appropriately sized for the system charging current
(see back page).
An in-line fuse holder should be wired in the positive line no further
than 12” (305 mm) from the battery post.
Do not insert a fuse in the
fuse holder at this time.
Step 3: Battery #2 (engine battery)
Connect Battery #2 to the SunSaver Duo as shown in figure 4. The
engine battery should already be grounded to the vehicle chassis. Use
red wire for battery positive. Use wire appropriately sized for the system
charging current (see page 17).
An in-line fuse holder should be wired in the positive line no further
than 12” (305 mm) from the battery post.
Do not insert a fuse in the
fuse holder at this time.
Step 4: Solar
Ground the solar module(s) to the vehicle chassis with black wire.
Multiple 12V nominal solar modules may be wired together in parallel
and grounded with one wire. Use red wire for the solar positive connec-
tion to the SunSaver Duo. Use wire appropriately sized for the system
charging current (see page 17).
