Learn how to troubleshoot and fix a blank display issue on Growatt inverters.
A blank display can be caused by power issues, internal faults, or connection problems. Check the power supply and connections to ensure everything is functioning properly.
To reset your Growatt inverter, turn off the inverter, wait for a few minutes, and then turn it back on. This can help resolve minor issues.
A blank display on the Growatt inverter may indicate a failure in the power supply circuit or a complete shutdown due to safety protocols. Inverters are designed to protect themselves from potential damage caused by factors such as overvoltage, ground faults, or input issues. When the inverter detects an anomaly, it may disable output and present a blank screen to signal a fault condition. This could relate to the RISO measurement, where insulation resistance below a certain threshold triggers a safety shutdown to prevent electrical hazards.
The Growatt inverter displays a completely blank screen with no LED indicators illuminated. There are no alerts on the monitoring app, and production data shows a sudden drop to zero, indicating the system is not operational.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical systems to ensure safety and compliance with local codes.
Regular maintenance checks, including visual inspections of the solar array and electrical connections, can help prevent future occurrences of a blank display. Ensure that the inverter firmware is updated and that the system is monitored for any irregularities in performance. Additionally, consider installing surge protection devices to safeguard against voltage spikes.
