Solar inverter error
An inverter error can indicate a grid, protection, communication, photovoltaic string or settings issue. The error code is essential for initial review.
Possible causes
- grid voltage outside limits;
- AC or DC protection tripped;
- issue on one string;
- communication or monitoring error;
- settings, firmware or grid limitations.
Photos to send
- inverter screen with error;
- inverter label;
- AC/DC protection panel;
- monitoring app, if available;
- panels or technical area if relevant.
Safety
Do not open DC boxes, disconnect strings or work inside panels unless authorized. Photovoltaic systems can have dangerous voltage even when the grid is off.
