⚡ Easy DIY Troubleshooting & Common Fixes

🔧
Breaker fails to trip during overload, potentially damaging the inverter.
prob_01
Common root cause: Continuous overload exceeding the breaker's 20A nominal capacity or internal tripping mechanism failure.
Step-by-step solution: 1. Verify if the system current exceeds the breaker's 20A rating. 2. Power off the system; if overload persists, the breaker may be faulty and requires replacement.
💡 Pro tip: Properly size the breaker for the maximum expected current of your photovoltaic system.

⚖️ Seller Warranty & Marketplace Dispute Conciliation

Activate the warranty if the breaker exhibits a manufacturing defect, such as failing to trip under overload despite correct sizing, random tripping without apparent cause after proper installation, or if internal components show visible damage (e.g., damaged contacts) that prevents safe and effective operation, and was not caused by misuse or incorrect installation. Refer to the seller's warranty and marketplace return policy for details.
