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: S6-EH1P6K-L-EU

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 A and B to CT pins 9 and 10, respectively.

        Connect CT pins 3 and 4 to the power grid neutral (N) and live (L) terminals, respectively.

        Connect the RS485 output of the power meter to the RS-485 meter interface on the inverter using the provided network

        cable.

        Ensure the CT clamp is attached to the live wire of the power grid (the arrow indicates the end of the grid).

5 - Battery and Inverter Connection:

Use a standard pin-to-pin cable for connections between the battery and the inverter, as well as between batteries. Regardless of the number of inverters or batteries in parallel, the master battery should always communicate with the master inverter.

Connecting the Dyness A48100 with the Inverter:

• INV-BAT Connection: Connect from the master CAN IN to the inverter BMS 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 BMS 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 

To establish a local connection, ensure that your device's Bluetooth is enabled. 

Open the SolisCloud App and DO NOT LOGIN. 

      1: Navigate to the "More Tools" button on the bottom right-hand side.

      2: Click on "Local Operation."

      3: Select the "Connect with Bluetooth" button.

      4: Your device should appear in the "Nearby Devices" section. Click on your device and verify the serial number.

      5: Click on "Select account type." 

      6: Choose the "Installer" option.  

7: When accessing the inverter for the first time, you will be asked to set a password. Please follow the on-screen  

        instructions. Once the password is set, press “Set Password”.

 After saving the password, you will now be connected to your inverter.

Quick Settings Overview

The Quick Settings will appear on your screen.

These are the 5 basic settings that need to be configured for the inverter to function properly.

    1: Begin by setting the correct inverter time, or simply follow the phone time and press 'Next Step.'

    2: Choose the correct battery model, in our case “Dyness LV”. Click on 'Next Step.'

    3: In the third step, choose the correct meter and its placement.  

    4: In the next step, choose the correct Grid code for your area. 

    5: Grid Codes are sorted by country names. 

    6: Please choose the correct country code one and click on “Save”.

        (If you are unsure about which grid standard to use, contact your local energy provider for more details.)

7: In the last step of the Quick Settings, choose the mode that you want to apply. There are four different modes available:

• Self-Use Mode
• Feed-in Priority Mode
• Peak Shaving Mode
• Off-Grid Mode

 7: 

As a working mode you will most likely use the Self-Use mode. Self-Use Mode is designed to optimize the consumption of solar energy within a residential setting. In this mode, the system prioritizes directing all photovoltaic (PV) energy generated towards powering the home. Any surplus energy not immediately required by the household is intelligently stored in connected batteries. Only after the batteries are fully charged will any excess energy be fed back into the grid.In the absence of a battery system, the remaining surplus energy can be seamlessly exported to the utility grid, provided the system is configured accordingly. Most people in the European region will want to be using this mode over the others.

          A: Self-Use Mode is activated without any specific times set for the battery to charge/discharge, and the

              battery reserve is not switched on. 

              Note: Solis recommends activating the 'Allow Charging from Grid' option. Once the battery reaches the

              Forcecharge SOC, it will use the grid to charge the battery, preventing deep discharge.

          B: Activating the 'Time of Use Switch' will provide customers with several options to set charging/discharging 

              times and current.

          C: Setting the charge or discharge current within the range of 0-50A.

          D: If you want to set a specific charging or discharging value on your inverter, please first press "Add time"

              and then choose accordingly – Charging or Discharging Times.

          E: In the next step, please choose the actual time range for either Force Charge or Discharge.

          F: Once the Charge/Force charge period has been set, you will see the details on the screen.

          G: The Self-Use Mode provides you with the option to set a Battery reserve value. Please toggle the switch to 

               activate the battery reserve mode.

          H: You can set a range between 20% and 100% of the battery SOC. The inverter will strive to maintain the 

               battery at the chosen set level.

          I:   Finally, you have the option to establish a power limit that can be drawn from the grid side.

After selecting and configuring your preferred mode, the quick setup of the device is finished. 

On the app, you should now observe a graphical representation illustrating the energy flow within the inverter system. 

This graphic typically displays the current PV power, grid input, loads, and battery status. 

In the provided example, no loads are connected, thus the graphic will appear in grey. 

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.
