Maintenance Tips
- Inspect DC battery cables, PV input wiring, AC terminals, and grounding connections every 3–6 months; tighten any loose connections and check for corrosion.
- Keep ventilation openings, cooling fans, and air passages free from dust and debris to ensure efficient cooling and reliable operation.
- Regularly monitor the LCD display for fault codes, overload warnings, over-temperature alerts, or charging abnormalities. The inverter includes built-in protection systems that should be addressed promptly if triggered.
- Verify solar array voltage and battery settings remain within manufacturer specifications to protect the MPPT charge controller and battery bank.
- Maintain adequate clearance around the inverter and install it in a clean, dry, well-ventilated location away from direct sunlight, moisture, and corrosive environments.
- Periodically review charging priorities, battery charging current settings, and operating modes (Solar First, Utility First, SBU) to ensure optimal system performance.
- Clean the exterior with a soft, dry cloth; avoid solvents, abrasive cleaners, and high-pressure water.
- Inspect fuses, breakers, and protective devices regularly for signs of wear, overheating, or damage.
- Do not exceed the inverter’s 3000W continuous output, 6000W surge rating, or specified PV input limits.
