Maintenance Tips
- Clean solar panels every 1–3 months using clean water and a soft brush or microfiber cloth to remove dust, bird droppings, and debris for maximum efficiency.
- Inspect mounting structure, wiring, MC4 connectors, and DC isolators quarterly to ensure tight, corrosion-free, and safe electrical connections.
- Monitor inverter status regularly for fault codes, overheating warnings, and performance drops; address issues immediately to avoid system downtime.
- Keep inverter ventilation areas clean and unobstructed to maintain proper cooling and prevent thermal shutdown.
- Check battery (if included in configuration) monthly for state of charge, voltage stability, and terminal tightness to ensure long lifespan.
- Avoid deep discharging batteries and follow recommended charge/discharge ranges for LiFePO4 or lead-acid storage systems.
- Trim nearby trees or remove shading sources to maintain consistent solar generation throughout the day.
- Inspect breakers, surge protection devices, and grounding system every 6–12 months for safety and compliance.
