SunSaver MPPT Installation and Operation Manual

5.0 TROUBLESHOOTING
5.2 Common Problems
Problem: No LED indications
Solution: With a multi-meter, check the voltage at the
battery terminals on the SS-MPPT. Battery voltage must be
at least 7V to power the SS-MPPT.
Problem: The SS-MPPT 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 SS-MPPT. Input voltage must be greater than battery
voltage. Check fuses and solar wiring connections. Check
solar array for shading.
