OTE
: The SunSaver is very corrosion resistant. The case
is hard coat anodized, cover screws are stainless
steel, the circuit is encapsulated, and the termi-
nals are copper and nickel plated brass.
2. Confirm that the PV array and loads will not exceed the
current ratings of the SunSaver model being installed
(see specifications on page 2).
N OTE : Multiple SunSavers can be connected in parallel
to charge a single battery. Make sure each PV
sub-array does not exceed the solar rating of the
SunSaver, and be careful not to connect a load
that exceeds a single SunSaver’s load rating.
Separate loads can be connected to different
SunSavers.
3. CONNECTION ORDER The label has each system connec-
tion numbered from 1 to 6. This is the recommended order
of system connections. However, a different order will not
damage the controller.
4. BATTERY Connect the 12-volt (or 24-volt) system battery.
The green LED will not light. If a red LED (LOAD DISCON-
NECT) is provided with this model and it lights, the battery
charge state is low and should be recharged before
completing the installation.
N OTE : If the battery voltage is below 11.5 volts (or
23.0 volts), the load has been automatically
disconnected due to a very low battery charge
condition, and the battery must be recharged.
N OTE : If the battery voltage is between 11.5 and 12.0
(or 23 and 24) volts, the SunSaver will sometimes
power-up during initial installation in the LVD
(load disconnected) state. This will automatically
clear when the battery voltage rises above 12.6
(or 25.2) volts. The LVD can also be reset manual-
ly (only if the battery voltage is above 11.5 (or 23)
volts). First connect the SOLAR array (see step 5
below). Next disconnect and then reconnect the
BATTERY positive wire. The red LED will turn off
to indicate that the LVD has been reset.
