DC over-voltage fault codes
20 codes across 10 brands whose manufacturer wording names PV or DC input voltage above the inverter's input range.
A family groups codes by the manufacturer's wording. It does not mean the codes share a cause, a trip setting or a fix: the same words can describe different measurements on different hardware, so work each code from its own entry and its manufacturer's document.

Terms
Standards scope
Scope pages: what each standard covers and where it sits against the others. They do not reproduce the standard, and nothing on this page states what it requires. Work from the current published edition.
How codes are placed here
A code joins only when the manufacturer's own title or description contains one of these terms as whole words. The title decides first; Wattbench's fixes and search keywords are never read. A code that matches no family, or more than one, stays unclassified.
- DC over-voltage
- PV over-voltage
- over DC voltage
- DC input voltage too high
- DC input voltage exceeds maximum
- DC voltage too high
- DC voltage high
- DC voltage spike
- PV voltage high
- PV input voltage too high
- input voltage too high
- high string input voltage
- string input overvoltage
- exceeds the maximum input voltage
- voltage MPPT 1 too high
- voltage MPPT 2 too high
- MPPT1 voltage high
- voltage from the PV module is too high
