What Triggers EK Inverter Error 24?

If you've encountered EK Inverter Error 24, you're likely dealing with a DC overvoltage protection alarm. This error typically occurs when the inverter's input voltage exceeds safe operational limits. Let's explore why this happens and how to fix it—without turning your solar project into a guessing game!

Common Causes of Error 24

• Grid voltage fluctuations exceeding 600V DC input
• Faulty maximum power point tracking (MPPT) algorithms
• Improperly sized PV array configuration
• Degraded insulation resistance in cables

Step-by-Step Troubleshooting Guide

Here's how professionals tackle Error 24 in the field:

1. Check real-time DC voltage using monitoring software
2. Test PV string open-circuit voltage (Voc)
3. Inspect DC switchgear and junction boxes
4. Verify ambient temperature compensation
