Learn about the Solis RHI-5G inverter's Grid Volt High error, its causes, and solutions.
Grid Volt High indicates that the voltage from the utility grid exceeds safe limits. This can lead to inverter shutdown to protect the system.
Check the grid voltage levels and ensure they are within the inverter's specifications. If the issue persists, consult a technician.
The 'Grid Volt High' error indicates that the inverter has detected an input voltage from the utility grid that exceeds its maximum allowable threshold. Inverters are designed to protect both themselves and the solar array from damage due to over-voltage conditions. This fault can occur due to various factors, including high voltage readings during peak demand times or fluctuations caused by nearby industrial activities. The inverter employs internal voltage sensing mechanisms to monitor grid conditions continually, and when these exceed safe operational limits, it triggers a fault code to prevent damage.
The Solis RHI-5G inverter displaying a 'Grid Volt High' error typically presents with a flashing red LED indicator. Users may also observe alerts on the monitoring app indicating a production drop or system shutdown. The inverter may cease operation, leading to a noticeable decrease in energy generation.
Always ensure that any troubleshooting or maintenance is performed by a licensed electrician or certified solar installer to comply with safety standards and regulations.
To avoid a 'Grid Volt High' error in the future, regularly monitor grid voltage levels and ensure that the inverter settings are compliant with local utility specifications. Schedule periodic maintenance checks, and consider installing a surge protection device to safeguard against voltage spikes. Additionally, staying informed about local grid conditions during peak demand periods can help anticipate potential issues.
