1 - A heartbeat indication flickers the Status LED off briefly every 5 seconds.
A solid red Status LED indicates that a critical fault has been detected. Critical
faults typically indicate that the controller is damaged and requires service.
Battery Status LED Error Indications
High Voltage Disconnect R - G Sequencing
High Temperature Disconnect R - Y Sequencing
External Wiring Error R&G - Y Sequencing
Load Overcurrent R&G - Y Sequencing
Load Short Circuit R&G - Y Sequencing
Self-test Error R - Y - G Sequencing
Note:
LED error indications can be interpreted as follows:
“R - G sequencing” means that the Red LED is on, then the Green LED is on,
then Red LED is on....
“R&G - Y sequencing” means that both the Red LED and Green LED are on,
then just the Yellow LED is on, then Red and Green LED are on....
5.2 Common Problems
Problem: No LED indications
Solution: With a multi-meter, check the voltage at the
Battery terminals on the SunSaver and the Solar terminals
on the SunSaver. The solar module must be in good sun
and battery voltage must be at least 1 V to power the
SunSaver and activate the dead battery charging function.
Problem: The SunSaver is not charging the battery.
Solution: If the Status LED is solid or ashing red,
see Section 5.1 Error Indications. If the Status LED is off,
measure the voltage across the Solar input terminals of
the SunSaver. Input voltage must be greater than battery
voltage. Check fuses and solar wiring connections. The
solar module must in full natural sunlight.
Problem: No load output.
Solution: If the battery status indication is Solid Red, the
SunSaver is in the Low Voltage Disconnect (LVD) condition.
The load will automatically switch on when the battery
recharges to the Low Voltage Reconnect (LVR) threshold
voltage. See the specications in section 7.0 for LVD & LVR
settings.
NOTE: If the SunSaver model is SS-6-12V or SS-10-12V
(no load control feature), the controller may be damaged.
