8 fault codes documented
26.1/28.7 Amp Rating — Check phase ratings on three-phase homes
For certain inverter models (marked with **), phase ratings on three-phase homes must be checked to ensure circuit breaker ratings are larger than the inverter's Maximum AC Fault Current.
AC Cable Sizing Alert — Ensure correct cable capacity
The AC cabling for the inverter must be correctly sized to handle the maximum fault current output and operational current. Incorrect sizing can lead to system issues or failures.
DC Cable Sizing Alert — Use appropriate cable dimensions
The DC cables and plug connectors used in the system must meet specific size and temperature requirements to ensure safe and efficient operation.
Earth Fault Alarm — System alert for grounding issue
An earth fault alarm indicates a potential issue with the system's grounding. This is a mandatory safety feature required for all solar arrays.
Open Circuit Voltage or Short Circuit Current Mismatch — Potential wiring error
A discrepancy between the measured open circuit voltage (Voc) and short circuit current (Isc) and the module's specifications indicates a possible wiring fault within the PV system.
SE3000H Model Suffix — May indicate different options
Models with a suffix denoted by '*' (e.g., SE3000H-xxxxxxxxx*) may have different options and functionalities. These suffixes do not indicate a fault but differentiate specific product configurations.
Voltage and Current Mismatch — Wiring fault detected
If the measured open circuit voltage (Voc) or short circuit current (Isc) of the solar modules differ significantly from their stated specifications, it suggests a wiring problem within the system.
Voltage Drop/Rise Exceeds 1% — Check AC cabling
The AC cabling should ensure a voltage drop or rise of less than 1% for optimal system performance. Exceeding this limit can affect inverter operation.
