Huawei's industry-leading solar inverters also support high-voltage, direct current (HVDC) scenarios, a minimum power grid short circuit ratio (SCR) of 1. . The inverter's reactive power capability is enabled at night, and the PID protection is also activated during the night. Check that the PID compensation. . A Huawei inverter high string voltage alarm means the DC voltage from a solar panel string is too high, most likely due to too many panels connected in series or an incorrect altitude setting. To fix this, reduce the number of panels in the affected string, ensure the open-circuit voltage. . There are two main categories of Huawei error codes: 1. Many of these error codes are one-off events, but you should seek technical support if they persist – especially if you get the same Alarm ID many times. Overvoltage and under voltage errors. .
