Maintenance Tips

• Inspect all PV, battery, and DC cable connections regularly, ensuring terminals are clean, secure, and tightened to the manufacturer's specified torque.
• Keep the controller's cooling vents and heatsink free of dust, dirt, and debris to maintain proper airflow and prevent overheating.
• Disconnect PV arrays and battery power before cleaning or performing any maintenance on the controller.
• Periodically inspect breakers, fuses, wiring, and grounding connections for corrosion, loose hardware, damaged insulation, or signs of overheating.
• Monitor charging performance, battery voltage, and system status using the built-in display to identify faults or abnormal operation early.
• Keep the controller installed in a clean, dry, well-ventilated location, protected from excessive moisture, direct sunlight, and corrosive environments.
• Update firmware only when recommended by MidNite Solar to maintain optimal performance, compatibility, and system reliability.
• Schedule an annual inspection by a qualified solar technician to verify electrical connections, charging accuracy, grounding integrity, and overall system safety for reliable long-term operation.
