Support Service-Hopewind

(1) Standby mode:In this mode, the DC input switch is off and the external environment (e.g., insufficient irradiance) does not meet the inverter’s operating conditions. The inverter continuously performs self-checks and switches to operating mode as soon as operating conditions are satisfied.

(2) Operating mode:The inverter converts DC power from the PV strings into AC power and feeds it into the grid. If a fault is detected or a shutdown command is received, the inverter transitions to shutdown mode. If the PV input power falls below the grid‑connection threshold, it returns to standby mode.

(3) Shutdown mode:The inverter enters this state upon detection of a fault or a shutdown command during either standby or operation. Once the fault is cleared or a startup command is issued, the inverter reverts to standby mode.

Why does the screen not light up after the inverter is wired?

1.Use a multimeter to check whether the DC string voltage reaches the inverter’s start‑up voltage.

2.Verify that the DC polarity (positive and negative) is not reversed.

3.Ensure that the DC switch (if equipped) is in the "ON" position.

What’s the impact when AC output three-phase (L1, L2 and L3) cables of the inverter are reversed?

Hopewind inverters feature a three‑phase adaptive function, so incorrect phase sequence wiring does not cause any adverse effect.

Does the inverter consume electricity when it does not generate electricity at night?

At night, the inverter is in standby mode and consumes negligible electricity. Standby power consumption is less than 1 W for a single unit, and the maximum consumption for high‑power models does not exceed 5W.
