Inverter-Side CAN Cable Connection and Pinout

The pinouts match on both battery and inverter ends. Connect one end of the cable to the “BMS1” or “BMS2” RJ45 port of the inverter as shown below. You can use a CAT6 shielded cable to connect the two ports together. Be sure to use an ethernet cable tester to ensure both connectors were made correctly and the cable works. 

Pytes BAU CAN Connection

• From Solis Inverter to the Pytes Battery: Plug the other end of the CAN communication cable from the Solis inverter into “COM 1” on the Pytes battery cabinet.

• To the Pytes BCU: Connect another communication cable from the “CAN” port of the Pytes BCU to the “Port 0” on the Pytes battery BAU.

• Connect another communication cable from the “CAN” port of the BAU to the “COM 1” port on the bottom of the battery cabinet. 

The battery and inverter CAN port pinouts are identical.

Pytes BAU Dip Switch Configuration

Before the Solis inverter can understand the Pytes battery, you must configure the BAU DIP switches to broadcast the correct protocol.

• Verify Power: Make sure the isolation switch is in the off state before adjusting any switches.
• Set the DIP Switch: Locate the DIP switch on the BAU and set it to the following sequence: down, up, down, up, down, down.

Turning the System On

• Install Manual Service Disconnects (MSDs): Before initiating any power, ensure that the Manual Service Disconnects (MSDs) are fully and securely installed into the designated receptacles on each individual battery pack within the cabinet.
• Close the DC Isolation Switch & Power Switch: Locate the main DC disconnect switch on the Pytes battery and close it. Also, find the battery’s primary power switch and then turn it to ON. 

Battery Switch OFF Position:

Battery Switch ON Position: 

• Press the SW Button: Short press the “SW” button on the battery. The run light on the main control will begin to flicker, indicating that the system is successfully booting up.

• Verify Status LED: Check the LED indicator located on the outside of the cabinet door. The startup is successful when the LED illuminates solid green. (Note: For safety and proper operation, the cabinet door must remain closed during this process and standard operation). 

• Energize the Inverter: Only after the battery cabinet is fully initialized and showing a solid green LED should you proceed to turn on AC power to the inverter and also the Solis inverter's DC switch. Be sure to give the red E-Stop RSD button a clockwise turn to ensure it is open and not closed (pushed in).

Download the SolisCloud App & Register an Account 

• In the App Store/Play Store search “SolisCloud” and then download the app that has the same icon as this one: 

• Register a new Organization account if you are installer and have not yet set up an account yet. 
• Log in to SolisCloud 

SolisCloud App: Settings configuration

• Tap Service > Local Debugging > Connect with Bluetooth.
• Create a new password for logging in to the inverter
• Configure the Quick Settings. For the battery, select “PYTES HV"
• Once you reach the main overview screen tap “Settings” in the bottom right corner
• Scroll to the bottom and then tap “Device Upgrade” 
• Upgrade the firmware on all paralleled Solis inverter-chargers.
  • In the bottom menu bar, select Setting > Device Upgrade.
  • Upgrade the HMI and DSP.

Note 1: Upgrading inverter firmware is mandatory. 

Note 2: All Solis inverters must be use the same firmware version to operate normally. If you are connecting multiple inverters in parallel be sure they are on the same version.

For a guide on how to upgrade inverter firmware please see this article:

Upgrading Hybrid Inverter Firmware Locally

• After upgrading the firmware, in the phone app tap Battery Setting
• In the Battery Setting page, tap "Battery1Setting"
• Make sure the Battery Model is set to “PYTES HV” if it is not then you will need to first tap "Battery Model”, then tap “PYLON_LV”, and then tap “Save” in the top right corner of the screen.

Battery Settings and Energy Storage Mode Settings

Please see this guide for detailed explanations of each and every battery-related setting as well as energy storage and export power settings: Battery, Energy Storage, & Export Power Settings Explained 

• Set other inverter battery-related settings as required.For instructions on configuring inverter settings, refer to the full Solis manual or the article linked above. 
• After all the settings have been configured, check the overview page of the system.
  • Follow all manufacturer instructions to power up the inverter DC switch, and turn ON the batteries and other peripheral equipment.
  • Use the overview to confirm the battery SOC, battery communications, grid, and load.
  • Review and resolve any generated alarms.

• At this point, if the system is grid-connected, AC grid power is turned on.

• Exit the app once the system is running and all checks are complete.

Depending on your system and particular use case, there may be other settings that require configuration. Refer to the inverter manual for information on these settings.
