4 Signs Your Solar Inverter System Needs a Check-Up (And How to Read Its Alerts) Leave a comment
Is your solar system performing optimally? Learn to spot the 4 key warning signs of a problem and understand common error codes before they become costly repairs.
Your solar inverter system is a workhorse, but like any sophisticated equipment, it needs occasional attention. Ignoring early warning signs can lead to a big drop in efficiency or even a complete shutdown.
Here are 4 signs it’s time to call TMK ENERGIES for a system health check:
1. A Sudden Spike in Your Electricity Bill
This is the #1 indicator. If your bill suddenly looks like it did before you went solar, your system isn’t offsetting your usage as it should. This could be due to inverter issues, panel faults, or a grid connection problem.
2. Your Inverter Display is Off or Showing an Error Code
Blank Screen: Could be a simple tripped fuse or a major internal fault.
Common Error Codes:
“Grid Fault” or “No Grid”: Often a grid-side issue, but needs verification.
“Overload”: You’re trying to run more appliances than the inverter can handle.
“Low Battery” or “Battery Fault”: Indicates a problem with the battery connection, charge, or health.
3. Unusual Noises or Constant Fan Operation
A gentle hum is normal. But loud buzzing, clicking, or a fan that’s running at high speed constantly points to overheating or component stress that needs immediate attention.
4. A Visible Drop in Solar Generation (Check Your App!)
Most modern systems have a monitoring app. If you notice your daily kWh generation has steadily dropped, even on sunny days, it could mean a dirty string of panels, a shading issue (from new tree growth), or a failing panel.
Don’t wait for a total failure. Proactive maintenance saves money and extends your system’s life. [Schedule a professional solar system health check with TMK ENERGIES] to ensure you’re getting every rupee of savings you deserve.
