Maintenance Tips
- Clean solar panels regularly with a soft cloth and water to remove dust, dirt, and bird droppings for maximum efficiency.
- Inspect panels for cracks, loose frames, or hot spots after installation or storms.
- Keep all MC4 connectors and wiring dry, tight, and free from corrosion or sand buildup.
- Check charge controller settings periodically to ensure correct 12V battery charging profiles.
- Avoid shading on panels—partial shade can significantly reduce system output.
- Monitor battery voltage regularly; avoid deep discharge below safe levels to extend battery life.
- Ensure inverter is installed in a cool, ventilated area to prevent overheating during high loads.
- Do not exceed 1500W continuous load on the inverter; allow surge capacity only for short startup bursts.
- Inspect 2 AWG inverter cables for heat, wear, or loose lugs—tight connections are critical for safety.
- Keep ventilation fans and heat sinks on the inverter clean and unobstructed.
- Store batteries in a cool, dry place when not in use and maintain partial charge for longevity.
- Secure mounting hardware for panels to withstand wind, vibration, and weather exposure.
- Perform periodic system checks (voltage, current, charging rate) to ensure optimal off-grid performance.
