Maintenance Tips    

• Install in a cool, dry, well-ventilated indoor or weather-protected enclosure to maintain high MPPT efficiency (up to ~98–99%).
• Ensure heatsink fins stay dust-free; although fanless, thermal performance depends on passive cooling airflow.
• Regularly inspect PV input, battery output, and load terminals for tightness, corrosion, and heat discoloration.
• Use properly sized cables to reduce voltage drop—especially important at 80A max charging current.
• Keep PV array voltage within safe limits (up to 150V max input depending on system configuration) to avoid controller damage.
• Verify correct battery type settings (AGM, flooded, gel, lithium, user-defined profiles) for proper 4-stage charging.
• Periodically check battery temperature sensor (BTS) placement and condition for accurate temperature compensation charging.
• Monitor system via LED indicators or RS485 interface for fault codes, over-temp, or over-voltage warnings.
• Inspect fuses, breakers, and disconnects on both PV and battery sides to ensure safe isolation during maintenance.
• Avoid reverse polarity or incorrect string configuration—these are common causes of irreversible controller damage.
• Ensure proper grounding and surge protection (lightning protection recommended for outdoor PV arrays).
• Perform periodic system checks (every 3–6 months): torque verification, voltage validation, and PV performance review.
