(1) Standby mode: Standby mode mainly refers to the DC input switch is off when the external environment cannot meet the operating conditions of the inverter (e.g.,insufficient light). In this mode, the inverter keeps self-checking, and enters the operating mode once meeting the operating conditions.

(2) Operating mode: In operating mode, the inverter converts the PV series DC power into AC power and feeds it into the power grid. The inverter will enter the shutdown mode when detecting a fault or shutdown command. It will enter the standby mode when detecting that the PV series input power is lower than the grid-connected power generation conditions.

(3) Shutdown mode: The inverter will enter the shutdown mode in case of detecting a fault or shutdown command during standby or operation. In shutdown mode, the inverter will enter the standby mode in case of detecting that the fault has been cleared or the startup command.

The DC side of the Hopewind single-phase inverter can be configured with 1.1-1.2 times the rated power, and the three-phase inverter can be configured with 1.3 times or more the rated power. To avoid power loss on the DC side for a part of the time, it is generally recommended to design based on 1.2 times the rated power.

In addition, it is necessary to configure different super proportions according to different component specifications, such as high-power components of 182 and 210 specifications.

Yes, as long as the protocols match and are compatible.

1. Check whether the voltage of the DC series reaches the starting voltage of the inverter with a multimeter;

2. Check whether the positive and negative polarity of the DC series is reversed;

3. Check whether it is equipped with a DC switch, and whether the DC switch is in the place “ON”.
