LED Status Indicators

Indicator Color Status Meaning
Night or No Solar Input Off (flickers ON every 5 sec) Off No solar input detected; normal during night or extremely cloudy conditions.
Charging Green (heartbeat flicker) Flickers OFF every 5 sec Normal charging; solar input is active and functioning properly.
High Temp/Voltage Disconnect Red Flashing Overheating, overload, or high voltage disconnect detected. Check system conditions.
Sensor/Firmware Error Red Solid Potential sensor damage or firmware issues; requires diagnostic check.
Normal Battery with Load Green Fast Flash (2 sec) Battery is charged and providing power under normal conditions.
Low Battery Yellow Solid Battery is at half capacity; may need attention soon.
High Voltage Disconnect Red/Green Alternating High voltage detected; system disconnect to prevent damage.
High Temperature Disconnect Red/Yellow Alternating High temperature detected; system disconnect for safety.
Wiring Errors Red/Green - Yellow Alternating Wiring issues; check for shorts, reverse polarity, or overcurrent. No permanent damage.
Internal Temp Sensor Damage Red/Yellow/Green Alternating Internal temperature sensor may be damaged; check system health.
Low Voltage Disconnect Red Solid Low voltage detected; insufficient power to sustain operations.

Reset Procedure

  1. Verify and Correct Wiring:

    • Ensure all connections are properly made, especially the load and solar connections.
    • Check polarity carefully: the black wire with a white stripe is positive.

  2. Disconnect Power:

    • Disconnect solar panels and battery connections.
    • Remove fuses from battery lines to completely isolate power.

  3. Wait and Reconnect:

    • Leave the system disconnected for at least 5 minutes to reset.
    • Reconnect the battery first, then solar panels.
    • Ensure all connectors are secure and correctly installed.

  4. Test the System:

    • Power on the system and observe the LED indicators.
    • Use a multimeter to test the battery and solar output, ensuring voltages are within acceptable ranges.

  5. Final Checks:

    • If unusual LED sequences persist, consult the SunSaver manual or contact support for further diagnostics.
    • Regularly check and maintain the system to prevent future issues.
