6 FAQs about [Huawei photovoltaic grid-connected inverter parameters]

Can a professional set the grid parameters of the inverters?

Only professionals are allowed to set the grid parameters, protection parameters, feature parameters, power adjustment parameters, and grid-tied point control parameters of the inverters. If the grid parameters, protection parameters, and feature parameters are incorrectly set, the inverters may not connect to the power grid.

Can Huawei change the information on the sun2000l inverters?

Therefore, such information is provided for reference purpose only and constitutes neither an offer nor an acceptance. Huawei may change the information at any time without notice. This document describe the steps for commissioning the SUN2000L inverters.

Can a solar inverter connect to a power grid?

The standards of certain countries and regions require that the solar inverter must not connect to the power grid when the power grid frequency is lower than the lower limit. Specifies the voltage threshold for triggering reactive power compensation when low voltage ride-through (LVRT) occurs.

Can grid-connected PV inverters improve utility grid stability?

Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.

How do I connect a solar inverter?

Log in as Advanced User or Special User and set access parameters. Method 1: Click Auto. Search to connect to the solar inverter. Method 2: Click Add Devices, set access parameters, and click Add Devices. Set this parameter to SUN2000. If the solar inverter uses the MBUS for communication, set this parameter to MBUS.

Do I need to set a string connection parameter for a solar inverter?

You do not need to set this parameter if each PV string is separately connected to a solar inverter. The solar inverter can automatically detect the connection mode of the PV strings. Set this parameter to All PV strings connected if all PV strings are connected in parallel and then connected to the inverter in parallel.
