6 FAQs about [Huawei inverter medium voltage grid-connected voltage]

What is grid reconnection voltage upper limit (V)?

Grid reconnection voltage upper limit (V) The standards of certain countries and regions require that after the inverter shuts down for protection due to a fault, if the power grid voltage is higher than Grid reconnection voltage upper limit, the inverter is not allowed to reconnect to the grid.

What if fusionhome app grid voltage is too high?

1. Set the running parameters with FusionHome APP Grid voltage is too high >253VAC: increase the voltage for the “Grid connection voltage upper limit”. Grid voltage is too low <195.5: decrease the voltage for the “Grid reconnection voltage lower limit”.

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 you connect an inverter to a power grid?

The power cable between the device or component and the wiring terminal should be no longer than 2.5 m. Therefore, a fuse or a circuit breaker is recommended. To ensure that the inverter can be safely disconnected from the power grid when an exception occurs, connect an AC switch to the AC side of the inverter.

How to increase the over voltage protection of the inverter?

For example: if the inverter generate very often the alarm over voltage due to the grid voltage range, you can select the over voltage protection, increase with 10V and confirm. 2. Set the running parameters through NetEco

What if grid voltage is too high?

Grid voltage is too high >253VAC: increase the voltage for the “Grid connection voltage upper limit”. Grid voltage is too low <195.5: decrease the voltage for the “Grid reconnection voltage lower limit”. Grid frequency is too high >50.05: increase the frequency for the “Grid reconnection frequency upper limit”.
