Grid volt. Imbalance

What does 2035 mean?

The difference between grid phase voltages exceeds the upper threshold. This indicates an imbalance in the three-phase power grid, which can affect the inverter's stable operation.

• The difference between grid phase voltages exceeds the upper threshold.

Click steps to track your progress.

1. 1

   Monitor if the alarm occurs occasionally, indicating a temporary power grid abnormality. The SUN2000 automatically recovers when the grid stabilizes.

2. 2

   If the alarm persists, check whether the power grid voltage is within the acceptable range. If not, contact the local power operator.

3. 3

   If the alarm lasts for a long time, check the AC output power cable connection.
