Campbell Scientific Morningstar SunSaver-10 10A 12V Regulator User Manual

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).

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.

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.

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.
