A Huawei hybrid inverter is a type of inverter that converts solar energy (DC) into grid power (AC) and also supports battery storage for storing excess energy. What do I need before starting? Which models does this step‑by‑step guide apply to?
If the fault persists, contact your dealer or Huawei technical support. The impedance of the output phase wire to PE is low or the output phase wire is short-circuited to PE. Check the impedance of the output phase wire to PE, locate the position with lower impedance, and rectify the fault. The power grid experiences an outage.
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
If the ventilation and ambient temperature both meet requirements, contact your dealer or Huawei technical support. An unrecoverable fault has occurred on a circuit inside the inverter. Turn off the AC output switch and DC input switch, and then turn them on after 5 minutes. If the fault persists, contact your dealer or Huawei technical support.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
