Check List 

All DYNESS batteries have the same DIP switch settings and cable connections. 

Below is an example checklist for the B4850 battery and Powerbox Pro models:

• Power cables
• Parallel cables
• Communication cable between the battery and inverter
• Communication cables between batteries

Inverter Model: RHI-(3-4.6)K-48ES-5G

Important: Before starting, ensure that the battery and inverter sizes are compatible. Please refer to the DYNESS user manual for detailed instructions. It is recommended to use the battery in at least a 1:2 configuration.

 Step 1: Connect Cables to the Inverter

1 - Power Down Devices: Ensure both the inverter and the battery are completely powered off.

        Connect Cables to the Inverter:

        Power and Communication Cables: Begin by connecting the power cable and communication (comm) cable to the

        inverter.

2 - AC Terminal Wiring:

        Connect the power grid to the "AC-Grid" terminal and connect the "AC-Backup" terminal to the inverter if desired.

3 - PV Input Wiring:

        Insert the positive and negative terminals of the photovoltaic (PV) system into the corresponding positive and negative

        terminals of the DC input port on the inverter.

4- Meter Wiring:

        Connect meter interfaces 1 and 4 to the power grid's live (L) and neutral (N) wires, respectively.

        Connect interfaces 5 and 6 to the CT (Current Transformer).

        Use the network cable provided in the accessories to connect the power meter's RS485 port to the inverter's RS-485

        meter interface.

         Ensure the CT is clamped onto the live wire of the power grid, with the arrow pointing in the direction of the grid.

5 - Battery and Inverter Connection:

A standard pin-to-pin cable is used for connections between the battery and inverter, as well as between batteries. Regardless of the number of inverters or batteries in parallel, the master battery always communicates with the master inverter.

Connecting the Dyness B4850 with the Inverter:

• INV-BAT Connection: Connect from the master CAN IN to the inverter CAN port.
• BAT-BAT Connection: Connect from the master CAN OUT to the slave1 CAN IN, then from slave1 CAN OUT to slave2 CAN IN, and so on.

Connecting the Dyness Powerbox Pro with the Inverter:

• INV-BAT Connection: Connect from the master CAN IN to the inverter CAN port.
• BAT-BAT Connection: Connect from the master box CAN OUT to the slave1 box CAN IN, then from slave1 box CAN OUT to slave2 box CAN IN, and so on.

• The master unit's factory default setting is 0010, so there’s no need to open the cover to make any changes. You can use it directly as is.
• If only one Powerbox Pro is used, it will function as the master unit by default.

Master Box:

Slave Box:

• For slave units, open their covers and set the internal 1# module to 0000.

Step 2: Switch On the Battery

Turn on the ON/OFF switch for all batteries. Then, press and hold the master switch (SW) for 3 seconds to power on all the batteries.

For devices like the Powerbox Pro, press and hold the power switch for 3 seconds to power on the battery.

Step 3: Activate Breaker/Fuse Between Inverter and Battery

Install a DC breaker or fuse between the inverter and battery to protect both devices. Switch it on after turning on the batteries. 

If using the Powerbox Pro, you can simply turn on its built-in DC breaker located on the side of the box.

Now that the inverter is powered on, you can proceed with the necessary setup to ensure successful communication.

Step 4: Inverter Setup 

Battery Setting

1: Navigate to the menu: ENTER → Advanced Settings.

2: Enter the password: 0010. (press “Down”, “Down”, “Up” and “Enter”)

3: Go to Storage Energy Set → Battery Select → Dyness LV.

 4: Set your Overdischarge and Forcecharge SOC. 

5: Confirm your selection: Click “Save & Send”.

Work Mode Setting

Set your desired work mode. The inverter offers four working modes: Self-Use, Feed-In Priority, Backup, and Off-Grid Mode.

Note: When setting a specific mode, ensure that all other modes are disabled.

Here the example of the most used “Self-Use” Mode. 

Once the desired working mode is set, the inverter will operate normally.

Step 5: Charge Battery 

Initiate the inverter to start charging the battery to 100% to calibrate the State of Charge (SOC).

Step 6: Shut Down Procedures

For Powerbox Pro:

1. Disconnect the inverter's AC side.
2. Turn off the DC breaker on the Powerbox Pro.
3. Press and hold the Reset button on the master Powerbox Pro for 3 seconds to turn it off. The slave units will automatically turn off as well.
4. Disconnect the PV/Grid.
5. Turn off the inverter power switch to shut down the inverter.

For Modules in Parallel:

1. Disconnect the inverter's AC side.
2. Turn off the DC breaker between the battery and the inverter.
3. Disconnect the PV/Grid (ensure the battery communicates successfully with the inverter).
4. Turn off the inverter power switch to shut down the inverter.
5. Press and hold the master module's SW button to turn off all batteries, then switch off the ON/OFF switches on all batteries.
