Maintenance Tips

• Keep the inverter installed in a cool, dry, and well-ventilated location (14°F–104°F / -10°C–40°C) to prevent overheating.
• Ensure at least 6–12 inches of clearance around the unit so internal cooling fans can work efficiently.
• Regularly clean air vents and fan filters to prevent dust buildup that can reduce performance or cause thermal shutdowns.
• Inspect AC input/output terminals, battery cables, and PV connections for tightness, discoloration, or signs of heat stress.
• Avoid running continuously above 80–90% of the 3000W rated load to extend inverter lifespan and reduce stress on internal components.
• Periodically check MPPT solar input settings (90–230V range, max 250V open circuit) to ensure panels are correctly configured.
• Keep firmware/LCD settings (battery type, charging priority, and voltage parameters) properly configured for your battery system.
• Do not connect or disconnect solar panels, batteries, or loads while the inverter is running to prevent arcing damage.
• Use proper grounding and surge protection to protect against lightning and voltage spikes.
• Perform a monthly system check: verify charging behavior, output stability, and error-free operation under load.
