5. SOLAR First, be certain the battery (+ and –) is connected

correctly. Then connect the PV array to the SOLAR terminals.

Be CERTAIN that the PV + and – wires are connected

correctly. The green LED will light if the array is connected

during the daytime.

AUTION

Remember that the PV array will generate

power whenever in sunlight. Also, be careful

not to SHORT-CIRCUIT the PV array while

connected to the controller, since this will

DAMAGE the controller.

6. LOAD Turn the load off. Connect the load to the LOAD

terminals, and then turn the load on.
If the load causes the red LED to turn on (for models with

LVD) soon after the load was activated, the battery must be

recharged. (see Section 6.2)

7. SEALED OR FLOODED SELECT The SunSaver is shipped

with a jumper installed between the LOAD-negative terminal

(connection 5) and the SEALED OR FLOODED SELECT ter-

minal. With this jumper installed, the SunSaver is configured

for charging SEALED batteries.
If your PV system has a FLOODED battery, simply remove

the jumper to change the SunSaver to a flooded battery

charger. (see Section 6.2)
The SunSaver can be changed between SEALED and

FLOODED as many times as you wish by using the jumper.

Save the jumper for future use in case your battery type is

changed. If the jumper is lost, a wire can also be used.

8. For safety and the most effective lightning protection, the

negative conductor of the PV system should be properly

grounded. The SunSaver connects the PV-negative, Battery-

negative and Load- negative internally per UL recommenda-

tions. No switching is done in the negative current path.
