Error 027 | The grid voltage is too high. |
Grid overvoltage | The Solar Inverter monitors |
the lower and upper admis- | |
| sible grid voltage limits in |
| |
| exceeds the upper limit |
| (Umax = 264 V), the Solar |
| Inverter will automatically |
| switch off and will only |
| restart when the voltage |
| value drops below the |
| upper limit again. The shut- |
| down can already be trig- |
| gered if the voltage rises |
| above the upper limit for |
| a short time. |
Ask your power supply company about the stability and design of the grid.
Errors 028 to 030 The Solar Inverter has detec-
Surge fault ted a high voltage peak in the injecting phase.
