Identification of Parts
Operation
Connection
When connecting multiple Renogy devices to Bluetooth through the HUB for the first time, each device needs to be connected to the HUB and registered on Renogy DC Home App SEPARATELY. This process is used to assign an address to each device, which is equivalent to registering an ”ID card”. After each device performs data transmission, all devices can be connected to the HUB and operate together with the App. The “ID card” won’t be affected by the power failure, so this process is only needed at the first connection.
Step 1
Connect the battery to the POWER port of the HUB using the power cable;Press the orange spring terminal, insert the power cable and connect it tightly.
Step 2
Connect the BT-2 Bluetooth module to the PRIMARY port of the HUB; Put the switch at RS485.
Step 3
Connect one Renogy device to the HUB; Register the device on the DC Home App via BT-2 Bluetooth module.
Take the Smart Lithium Battery as an example. Use a communication cable to connect the UP port of the battery to any SECONDARY port of the HUB.
Open the Renogy DC Home app, connect your phone/tablet with BT-2 via Bluetooth. After successfully registering the battery as a device on the App, you
can read the battery data on your phone.
Note： In this step, only one SECONDARY port can be used to connect to devices.
Step 4
Before connecting the next device, disconnect the previous device from the SECONDARY port;
Repeat Step 3 to connect another Renogy device.
The diagram shows connecting a charge controller to the HUB.
Step 5
Repeat Step 4 to connect any other devices.
The diagram shows connecting an inverter to the HUB.
Step 6
The last step is to reconnect all registered devices to the HUB; All devices will be automatically connected to the App.
