Another common issue involves low output power, often caused by environmental factors like shading or dirty panels. Overvoltage and under voltage errors are also typical Huawei inverter problems, often triggered by improper voltage input from the solar panels.
These point to more serious issues, such as hardware failures, grid faults, or overheating, and often require professional solar servicing. Now, let’s break down some of the most common Huawei inverter fault codes, including what they mean, and how you can troubleshoot them. 1. Error Code 202 – Abnormal invert circuit
Huawei inverters – helpfully – come with an industry-leading self-diagnosis system to detect faults and then display those Huawei inverter fault codes on the unit. You may also find your Huawei inverter problem on your app – but, either way, they’re basically telling you what’s wrong.
