IoT Connection: After Hub 2000 is powered on, the IoT indicator starts to flash rapidly, and the device automatically enters the IoT connection. Users can directly connect to IoT on Zendure App.

Tips:

• After the device is bound to Zendure Apps, when SolarFlow is turned on again, the IoT indicator light flashes slowly until it can communicate with the Zendure App.
• If you want to re-bind the account and reset the IoT connection, please press and hold the IoT button for 3 seconds to start the IoT connection.
• Hub 2000 & AB1000o r AB2000 or SuperBase V Hardware Reset:Press and hold the IoT button 10 seconds to reset Hub 2000 & AB1000 or AB2000 or SuperBase V .

Tips:

• Both Solar panels and AB1000 or AB2000 or SuperBase V power supply can wake up Hub 2000.
• If the Hub 2000 is connected to a SuperBase V, it is recommended that you include at least one Solar Panel in your system, connected to the battery using a Solar Connector to XT-90 Cable. This will allow the battery to “wake up” even if its energy is completely drained, as long as there is some power coming in from the solar panel.
  If the battery completely drained, please follow the steps below to reactivate it.
  If there is input power available, press the Power Button for 1 second on the battery to initiate charging.
  If there is no input power available, you will need to supply the battery with AC power first.
• To protect the battery, AB1000 or AB2000 will be turned off at the factory, so please activate the battery by turning on SolarFlow for the first time (press and hold the IoT button for 2 seconds).
• Before unplugging a connection, please turn off SolarFlow .

Operation Guidelines:
Tips:
The working process of SolarFlow as follows:
First the Hub 2000 pwered on, then it will enter the working state (the Hub 2000 indicator will lit green), second the IoT function will be awakened, and the device will directly enter Wi-Fi connecting state (the IoT indicator flashes green), and finally, the Hub 2000 will send a signal to activate AB1000 or AB2000 (the AB1000 or AB2000 indicator flashes green for 2 seconds before entering a steady state).
If you’re using a SuperBase V, please follow the steps below to power up your Hub 2000 and establish the IOT connection.

1. Press and hold the SuperBase V Power Button for 1 second to turn it on.
2. Open the Zendure App, then press and hold the IOT Button on your SuperBase V for 3 seconds.
3. In the app, turn on the Parallel Switch to provide power to the Hub 2000.
4. Press and hold the IOT Button of your Hub 2000 for 3 seconds to finish making the connection.

Operation Guidelines:

Tips:

• Choose one of bluetooth or Wi-Fi on Zendure App, Wi-Fi is preferred .
• When your Hub 2000 is connected to either a SuperBase V, and power is being supplied to the solar input, your Hub 2000 will automatically turn on. If no battery is connected within 5 minutes, the Hub 2000 will initially switch to bypass mode and direct power to the micro-inverter (at a default output of 200W, determined in the Zendure App). However, if a SuperBase V is connected within this 5-minute window, the SolarFlow will continue to operate in its default mode.
  If your Hub 2000 is connected to a SuperBase V, and it’s still receiving solar input power after being turned off, it will turn itself back on after 10 minutes and operate in bypass mode, directing power to the micro-invertor at a default of 200W (determined in the Zendure App).
  If your Hub 2000 loses its Wi-Fi connection while receiving solar power, it will automatically switch to bypass mode and output power to the micro-inverter at a default of 200W (determined by the Zendure App).

Installation

• If you wish to verify and commission your solar system immediately, complete the installation when the weather is sunny.
• It is recommended that at least two people participate in the installation.
• Please remember whether connecting or disconnecting Hub 2000 with AB1000 or AB2000 or SuperBase V , solar panels or Microinverters.make sure SolarFlow is turned off by ways of below .
• Press and hold IOT Button for 6s to shut off SolarFlow.
