Grid Voltage causing Shutdowns? | Blog

This has never been an issue because the inverter voltage could always increase if the grid voltage was high. However, since changes to AS 4777.2 became effective on 9 October 2016, inverters have been limited to a 255V output. Thus, if the grid voltage is already high, your inverter is no longer able to overcome it and, instead, shuts itself off.

What is grid over-voltage?

Grid Over-Voltage. The power grid voltage is beyond the upper threshold or the over-voltage duration exceeds the value specified by HVRT. 1. If the alarm occurs occasionally, the power grid may be abnormal temporarily. The inverter automatically recovers after detecting that the power grid becomes normal. 2.

What is startup voltage lower threshold of grid connection (V)?

Startup voltage lower threshold of grid connection (V) According to the standards of certain countries and regions, after the inverter is powered on for the first time for grid connection, if the power grid voltage is lower than Startup voltage lower threshold of grid connection, the inverter is not allowed to connect to the grid.

How do I know if a grid voltage is too high?

The grid voltage exceeds the higher threshold or the high voltage duration has lasted for more than the value specified by HVRT. Check the cross-section and all contacts near the inverter and distribution board. Turn off the inverter and measure voltage on the inverter AC terminal and on other end of the cable line in the distribution box.

How do I fix a Huawei inverter error code?

Turn off the AC output switch and then the DC input switch. After 5 minutes, turn on the AC output switch and then the DC input switch. If the fault persists, replace the board.
