6.2 Wiring Sequence
Follow the wiring sequence strictly to prevent damage to the controller or other components:
- Connect the Battery: First, connect the battery to the BAT+/- terminals. Ensure correct polarity. The controller will power on.
- Connect the Solar Panels: Next, connect the solar panels to the PV+/- terminals. Ensure correct polarity.
- Connect the DC Load: Finally, connect your DC load to the LOAD+/- terminals.
To disconnect the system, follow the reverse order: disconnect the load, then solar panels, then the battery.
6.3 Recommended Cable Size and Fuse
Proper wire gauge and fusing are essential for safety and performance. Refer to the table below for recommendations:
Figure 6.2: Recommended wire gauge and fuse sizes for the GCSOAR 60A MPPT Charge Controller. For a 60A controller, 4 AWG wire is recommended for both solar panel/battery and load connections, with fuses rated at 100A or greater.
| Connection | Wire Gauge Recommendation | Fuse Recommendation |
|---|---|---|
| Solar Panel / Battery | 4 AWG | ≥ 100A |
| Load | 4 AWG | ≥ 100A |

9. Troubleshooting
This section addresses common issues you might encounter with your GCSOAR MPPT Charge Controller.
- Controller Not Powering On:
- Check battery connections and polarity. Ensure the battery voltage is within the controller's operating range (12V/24V).
- Verify battery fuse is intact and properly connected.
- No PV Charging:
- Check solar panel connections and polarity.
- Ensure sufficient sunlight is reaching the panels.
- Verify PV input voltage is within the controller's acceptable range (Max 100V).
- Check for any shading on the solar panels.
- Load Not Working:
- Check load connections and polarity.
- Verify the load control mode settings (e.g., if in light control mode, it will only turn on at dusk).
- Check if the battery voltage is too low, triggering low voltage disconnect.
- Ensure the load current does not exceed the controller's rated capacity.
- Inaccurate Readings:
- Ensure the Remote Temperature Sensor (RTS) cable is properly connected and placed near the battery for accurate temperature compensation.
- Verify battery type settings match your installed battery.
- WiFi/App Connectivity Issues:
- Note that the Cloud-Box-M2 module is generally not available or supported for this model.
- If using an optional Bluetooth module, ensure it is correctly connected and within range. Bluetooth range is typically limited (e.g., ~25 feet).
- Check for the correct app (e.g., SolarMate) on your device's app store. Some users have reported issues with app availability or functionality for Android.
- Over-voltage/Surge Issues (especially with Lithium batteries):
- Ensure battery parameters (especially maximum charge voltage) are correctly set for your specific lithium battery type. Incorrect settings can lead to overcharging or voltage spikes that trip inverters.
- If issues persist, contact technical support.
