6 FAQs about [Huawei photovoltaic inverter circuit diagram]

How does a PV inverter work?

The inverter connects to four PV strings and tracks the maximum power point of the PV strings through two maximum power point tracking (MPPT) circuits. It also converts DC power into three-phase AC power through an inverter circuit. Surge protection is supported on both the DC and AC sides.

How does a solar inverter work?

The solar inverter receives inputs from 20 PV strings. The inputs are grouped into 10 MPPT circuits inside the solar inverter to track the maximum power point of the PV strings. The DC power is then converted into three-phase AC power through an inverter circuit. Surge protection is supported on both the DC and AC sides.

What if my Huawei solar inverter alarm persists?

If the alarm persists, contact Huawei technical support. Cause ID = 1–20 This alarm is generated when the PV string status is abnormal due to the following conditions: a single PV string is lost; both 2-in-1 PV strings are lost; one of the 2-in-1 PV strings is lost. Check whether the solar inverter terminals are properly connected.

Why is my Huawei solar inverter NOT working?

Turn of the AC output switch and then the DC input switch. Turn them on after 5 minutes and wait for the solar inverter to connect to the power grid. If the fault persists, contact your dealer or Huawei technical support. Cause ID = 1 The fuse is not in position or is blown. Cause ID = 2 The two relays on the breaking board are open-circuited.

How to install Huawei inverter outdoors?

You are advised to install the inverter in a sheltered place or install an awning over it. The inverter will be corroded in salt areas. Before installing the inverter outdoors in salt areas, consult Huawei. A salt area refers to the region within 500 meters from the coast or prone to sea breeze.
