The solar inverter is the heart of your solar power installation, converting variable DC current into stable 230V AC current. When an inverter trips or displays a warning code, solar generation halts.
1. Common Inverter Warning Codes
- Grid Fault / AC Voltage Out of Range: Common in rural and suburban Karnataka when grid voltage fluctuates above 253V or below 190V. Inverters disconnect to protect home appliances.
- PV Isolation / Ground Fault: Typically occurs during rainy mornings when moisture enters junction boxes or damaged cable insulation touches mounting metal.
- Over Temperature / Fan Error: Happens when dust blocks heat sinks or cooling fans fail. Ensure the inverter is installed in a shaded, well-ventilated location.
2. Battery Bank Maintenance
For tubular lead-acid batteries, check electrolyte levels every 2 months and top up with pure distilled water. Ensure terminals are coated with petroleum jelly to prevent corrosion. For modern lithium LFP batteries, verify the Battery Management System (BMS) communication cable is securely seated.
3. When to Bring It to Our Repair Bench
Never attempt internal circuit board repairs yourself due to lethal high-voltage DC capacitors. Powerr Technologies operates a dedicated repair workshop on KRS Main Road, Srirangapatna with specialized diagnostic oscilloscopes and replacement component boards.
