Error 027

· Grid overvoltage 3-phase

Your Solar Inverter is equipped with an intrinsically safe 3-phase grid monitoring system that complies with E DIN VDE 0126- 1-1. The voltage level of phases L1, L2, and L3 is continuously monitored. If it rises above the maximum admissible limit value, the Solar Inverter will stop the injection and only restart when the voltage value drops below the maximum admissible limit value.

Errors 031 to 033

· Grid overvoltage > 10 percent

If the voltage of the injecting phase has exceeded 253 V for more than ten minutes, the Solar Inverter will stop the injection and only try to restart when the grid voltage is within the admissible range again. The functioning method complies with E DIN VDE 0126-1-1. If the applied grid voltage at phase L2 is higher than 253 V for more than 10 minutes, for example, «error 032» will be flagged.

Errors 028 to 030

· Surge fault

Your Solar Inverter continuously monitors the quality of the AC grid. If there are high voltage peaks in the grid, the Solar Inverter will stop the injection and try to restart.

If such a surge impulse is detected at energy unit 3, for example, «error 030» will be flagged.

Errors 034 to 036

· Control fault

Your Solar Inverter is equipped with a self- monitored micro controller as a standard feature. If a fault occurs in the control sequence, the Solar Inverter will stop the injection and will only restart when the fault has been eliminated. If a fault occurs in the control circuit board of the third energy unit (upper energy unit), for exam- ple, «error 036» will be flagged.
