Maintenance Tips

• Solar Panels (18 x 415W):

  • Routine Cleaning: Clean the panels every 1-2 months using a soft cloth and water with mild soap to remove dirt, dust, and debris. Avoid harsh chemicals or abrasive materials to prevent panel damage.
  • Inspect for Physical Damage: Regularly check the panels for cracks, discoloration, or wear that may affect performance. Damaged panels should be replaced promptly.
  • Optimal Sun Exposure: Ensure that the panels are not shaded and are placed at the correct angle to maximize sunlight absorption, particularly during winter or cloudy days.

• Lithium Battery (20.48KWh LifePo4):

  • Charge Maintenance: Keep the battery charge between 20% and 80%. Avoid fully discharging or overcharging, as both can decrease the battery’s lifespan.
  • Storage Temperature: Store the battery in a temperature-controlled environment, ideally between 32°F (0°C) and 113°F (45°C). Extreme temperatures can cause damage and reduce efficiency.
  • Health Checks: Regularly monitor the battery’s voltage and charge cycle count. A significant drop in performance or irregular voltage readings may indicate the need for replacement.

• Inverter (18000W 48VDC to 120/240VAC):

  • Proper Ventilation: Ensure the inverter is placed in a well-ventilated area and that the cooling fans and vents are kept clear of dust and debris to prevent overheating.
  • Monitor Output: Regularly check the inverter’s output voltage and efficiency. If the system shows error codes or performance issues, address them promptly to avoid potential damage.
  • Check Wiring Connections: Inspect wiring for any signs of wear, loose connections, or corrosion. Secure or replace damaged parts as necessary.

• Charge Controller:

  • Correct Configuration: Double-check that the charge controller is set up properly to suit the 48VDC system. This ensures efficient energy conversion and protects the battery from overcharging.
  • Monitor Charging: Keep an eye on the battery’s charging status to prevent overcharging or undercharging, which can both reduce battery life.

• System Wiring & Electrical Components:

  • Regular Inspection: Inspect all electrical connections, wiring, and components for wear, damage, or corrosion. Tighten any loose connections and replace damaged wires immediately to avoid system malfunctions.
  • Waterproof Seals: Ensure that all outdoor electrical components are properly sealed and protected from moisture to prevent corrosion and short circuits.

• Battery Maintenance:

  • Voltage and Performance Monitoring: Perform regular voltage checks to confirm that the battery is functioning correctly within the recommended range.
  • Avoid Over-Discharging: Ensure that the battery is not over-discharged, as this can shorten its lifespan. Aim to recharge before reaching very low levels of charge.

• Seasonal Maintenance:

  • Panel Adjustment: Adjust the angle of the solar panels seasonally to optimize sunlight absorption, particularly during winter when the sun’s angle is lower.
  • Clean Snow and Debris: In cold months, regularly remove any snow, leaves, or other debris from the panels to maximize performance.

• Annual Professional Maintenance:

  • System Checkup: Schedule an annual professional inspection to ensure all components are functioning correctly. A technician can check for any wear, recommend upgrades, and ensure the system’s efficiency.
  • Firmware & Software Updates: Stay up to date on firmware updates for the inverter and charge controller, as these updates can enhance performance and fix potential bugs or vulnerabilities.

• Battery Performance & Safety:

  • Keep within Voltage Range: Avoid exposing the battery to voltages outside the specified range (48V). Operating beyond this range can damage the cells and reduce overall capacity.
  • Temperature Sensitivity: Always monitor the temperature of the battery to avoid overheating. Ensure the battery compartment is well-ventilated and away from heat sources.
