FAQs 6

Can the inverter be extended with the Huawei battery?

Thanks to the integrated 800V high-voltage battery connection, the inverter can be extended with the HUAWEI Battery. The optional HUAWEI Smart Meter is connected via the integrated RS485 interface and provides information about house consumption and grid feed-in.

What is a Huawei inverter?

Huawei inverters are becoming a benchmark for solar energy in residential and commercial applications. Huawei is a well-known brand in the solar energy sector.

How to set a grid connection with limited power (kW)?

Set grid connection with limited power (kW) parameters and click Submit. Set this parameter to Grid connection with limited power (kW). Set this parameter to Smart meter. Otherwise, the function will not take effect. When the inverter has no output power, set this parameter to Positive if the active power reading of the power meter is positive.

How to enable grid connection with limited power parameters?

To enable this function, you need to set power meter, inverter, and grid connection with limited power parameters. This section describes how to set grid connection with limited power parameters. Before setting the parameters, ensure that a power meter has been connected to the SmartLogger.

How do I export rated power to the power grid?

The inverter can export its rated power to the power grid. Set this parameter to SDongle/SmartLogger when the SmartLogger1000A is connected. If multiple inverters are cascaded, set this parameter to SDongle/SmartLogger. If there is only one inverter, set this parameter to Inverter.

What if the inverter has no output power?

When the inverter has no output power, set this parameter to Positive if the active power reading of the power meter is positive. Otherwise, set this parameter to Reverse. Total power: controls the total power at the grid-tied point to limit the power fed to the power grid.
