412
Fixed voltage mode has been selected instead of MPP voltage mode, and the fixed voltage has been set to too low or too high a value

¿Qué significa 412 ?
The inverter is configured for fixed voltage operation, but the set DC input voltage is outside the acceptable range for the connected PV array or the inverter's capabilities. This prevents optimal power generation and grid feed-in.
Causas comunes
- Incorrect parameter setting for the fixed voltage mode
- Mismatch between the PV array voltage characteristics and the programmed fixed voltage
