Description: TBB Rio SUN II Inverter + DYNESS Powerbrick Battery Start-up Protocol


INTRODUCTION

Valid Inverters: TBB Rio SUN II Series

Valid battery:

  • Dyness DY-POWERBRICK-14336

Additional devices:

  • TBB-E4-MONITOR
  • Smart Meter TBB-SDM-230
  • TBB-ETHERLINKER


STEP 1: ELECTRICAL CONNECTION BETWEEN INVERTER AND BATTERIES

It is strongly recommended to read the user manual of both the TBB inverter and the DYNESS battery, and to perform the installation exactly according to the manufacturers' requirements.

Connect the DC cables from the inverter to the battery (cables included in the battery). It is very important to ensure the correct polarity before connecting to the inverter.

The positive cable (red) is connected to the BAT + port of the inverter (located at the bottom left of the inverter), while the negative(black) is connected to the BAT - port of the inverter (located at the bottom left of the inverter).

It is also necessary to install a correctly dimensioned protection fuse between the inverter and the battery.

STEP 2: CONNECTION OF THE COMMUNICATION CABLE BETWEEN THE INVERTER AND THE BATTERY

This communication cable is an RJ45 cable that comes with the battery. It is important to perform this step because otherwise the inverter will not detect the batteries.

In the batteries there are 3 cables, depending on the type and brand of inverter. In this case it is necessary to choose those that in the label"INVERTER" is written"VICTRON".

To connect this cable there are 2 options:

Direct connection between inverter and battery:

  • On the battery, the communication cable must be connected to the CAN IN port. The side of the cable to be connected is the one marked"BATTERY". If several batteries are placed in parallel, apart from the connection with the inverter, they have to be connected to each other via RJ45 cable (it is a shorter cable that is also present in the batteries). The connection is made between CAN OUT of one battery and CAN IN of the next one.
  • In the inverter, the communication cable has to be connected to the ComSyncIn port. The side of the cable to be connected is the side marked"INVERTER".

Connection through the TBB-E4-MONITOR: This is an accessory that is mandatory and necessary when you want to inject surplus solar production to the grid, in case of inverter paralleling, three-phase connection and AC Coupling. It also serves as a display for local monitoring, as an option.

  • On the battery, the communication cable must be connected to the CAN IN port. The side of the cable to be connected is the side marked"BATTERY". If several batteries are placed in parallel, apart from the connection to the inverter, they have to be connected to each other via RJ45 cable (also present in the batteries). The connection is made between CAN OUT of one battery and CAN IN of the next one.
  • In the TBB-E4-MONITOR the cable has to be connected to the port in the lower left corner(Port 4) by means of an adapter on which is written"E4" and"CAN-BAT" (it is included with the monitor). The side of the communication cable to be connected to the adapter(CAN-BAT) is the one marked"INVERTER".

  • Also, the TBB-E4-MONITOR has to be connected to the inverter by another RJ45 cable. This cable is included with the monitor. The connection is made from the RJ45 port of the TBB-E4-MONITOR(Port 3) to the ComMON port of the inverter itself.

STEP 3: DRIVING THE BATTERY DIPS

On the front of the batteries there are some dips that have to be placed in different ways depending on the inverter brand and the amount of batteries there are. In this case:

Single battery:

DIP 1,2,3,4 in OFF position.

Several batteries in parallel: Both the master battery (connected directly to the inverter) and the slaves with DIP 1,2,3,4 in OFF position.

STEP 4: SWITCH ON BATTERIES AND INVERTER

  • First, switch on the batteries. Turn on the ON/OFF switch ( ON position). Then press for 3 seconds the WAKE/SLEEP button of the battery or of the master battery in case there are several batteries. The slave batteries will switch on automatically after a few seconds.

  • Second, turn on the inverter by pressing the black button on the lower left side of the inverter for 3 seconds.

STEP 5: SET UP THE INVERTER

For the correct operation of the TBB + DYNESS ecosystem it is necessary to make a series of adjustments to the inverter parameters. This set up can be done in several ways:

Using the LCD screen of the inverter itself.

By default, the LCD display shows information about the battery, grid, solar production and electricity demand.

To access the configuration , press and hold the"ENTER" button. Using the"UP" and"DOWN" buttons you can navigate through the configuration menu.

To change a specific parameter, press the"ENTER" button and modify its value using the"UP" and"DOWN" buttons. To change certain parameters, the inverter must be in standby mode, in which case the SETTING icon on the display will be off.

To confirm the modification, it is necessary to press the"ENTER" button again. If the modification has been successful, the"SUCCESSFUL" icon will remain lit for 1 second. If the modification was not successful, the"FAIL" icon will remain lit for 1 second. If you want to cancel the modification (by mistake, for example), press the"ESC" button.

The parameters that need to be changed when there is a TBB + DYNESS system are as follows:

  • Parameter 10 (battery type). Select 6 (Lithium).
  • Parameter 20 (Low SOC protection threshold). Select the minimum battery percentage. Recommended 10-20%.
  • Parameter 21. (Float current). When the lithium battery sends a charge current of 0A (when 100% charged), by default, the float charge current is 2A. Select 0 (Disable) and the float charge is turned off.
  • Parameter 35. (Maximum AC charging current). Select the maximum battery charging current, in this case 140A.

Using the TBB-E4-MONITOR

To correctly connect the TBB-E4-MONITOR and display the data, follow the steps described in step 3. To interact with the TBB-E4-MONITOR, simply turn on the inverter and wait for 10 seconds.

It is recommended to read the instruction manual and the first use manual that can be found on the Visiotech website.

By default, the TBB-E4-MONITOR display shows battery, grid, solar production and power demand information. To change the parameters it is necessary to click on the icon circled in red red icon (SYSTEM) and within that icon choose GENERAL SETTINGS.

The parameters that need to be changed when there is a TBB + DYNESS system are the following, and all of them are changed inside General Settings in Battery Settings.

  • Battery Type: Choose in Battery Type the Lithium Battery option.
  • Low SOC Protection Threshold. Choose the minimum battery percentage, in Low SOC Disconnect. Recommended 10-20%.
  • Float current: When the lithium battery sends a charge current of 0A (when 100% charged), by default, the float charge current is 2A. Select Disable and this turns off the float charge.
  • Maximum AC charging current. Select the maximum battery charging current, which is Max Charging Current (in this case it is 140A)

Using the TBB NOVA application via Bluetooth or WiFi.

In this case it is necessary to have connected either the TBB-E4-MONITOR or the Kinergy WiFi accessory, which is the antenna that comes with all inverters. In both cases they are connected to the ComMON port of the inverter.

The settings, using the App, can be changed either locally or once the installation is connected to the cloud. In addition to making the settings, it is strongly recommended to connect the system to the TBB cloud. Apart from being able to monitor remotely in real time, it gives an extra year of warranty.

The first thing to do is to download the TBB NOVA app, available on both iOS and Android.

If you want to connect to the cloud, you have to register (user name, cell phone, country, city, password and email account required), add the verification code that is sent to the email, go to LOGIN and then add the plant via QR or S/N (either from the Kinergy WiFi or from the TBB-E4-MONITOR).

If you do not want to connect to the cloud, go to LOCAL and go to Quick Setup.

Inside the App, in the interface, a series of installations appear, among which is the one you want to make the settings. Click on it and then click on INSTALL.

Then select GENERAL SETTING and BATTERY SETTING. In BATTERY SETTING change the necessary parameters:

  • Battery Type: choose under Battery Type the Lithium Battery option.
  • Low SOC protection threshold. Choose the minimum battery percentage, in Low SOC Disconnect. Recommended 10-20%.
  • Float current: When the lithium battery sends a charge current of 0A (when 100% charged), by default, the float charge current is 2A. Select Disable and this turns off the float charge.
  • Maximum AC charging current. Select the maximum charging current of the battery, which is Max Charging Current (in this case it is 140A)
