Huawei/Inverter - How does my Huawei inverter operate?

How does my Huawei inverter operate?

To best understand how your solar pv system will operate with a Huawei SUN2000 inverter, you need to understand their two main operation modes:

• Max Self-Consumption.
• Time-Of-Use(TOU).

Max Self-Consumption

This is the default operation mode of a Huawei SUN2000 inverter. In Max Self-Consumption mode, the solar pv system will essentially try to be as ecological as possible. The inverter will:

1. Firstly, try to send electricity from your panels to your property to cover your consumption.
2. Secondly, send any excess energy to the battery(s).
3. Lastly, send any further excess energy back to the grid.

The battery will only charge from the solar panels.

Your battery will only discharge when there is not enough solar panel electricity to cover the consumption.

Electricity will only be imported from the grid if the panels and/or the battery cannot cover the consumption.

TOU

Time-of-use mode can be used to configure specific charging and discharging periods. This is particularly useful for a Solar PV System when the days are shorter and darker. Home owners can typically choose a night tariff with their electricity provider, meaning they can import electricity at a cheaper rate during the night. With TOU, they can then charge their battery over night, and discharge it during the day.

A maximum of 14 charging and discharging segments can be configured.

There must be at least one charging period and one discharging period.
