This fork supports CAN bus communication with inverters supporting the CANBUS Protocol compatible with Pylontech V1.3 and Goodwe V1.5. Additionaly values of Deye inverters are read via RS485 via Modbus. All values are send to Home Assistant.

Note Pylontech uses 15s/48v Goodwe uses 16s/51.2v @3.2v/cell nominal. Other battery profiles that utilise the pylonton/goodwe protocol with differnt cell counts may also work, eg Alpha Ess Smile, BYD Battery-Box LV Flex Lite Select the correct battery profile in the inverter to match your battery pack!

The ESP32 communicates with the JK-BMS using the RS485 port(GPS) which is in fact not RS485, it is 3.3V TTL so it can be directly connected to the ESP32. The ESP32 then sends the required CAN bus data to the inverter via a CAN bus transceiver.

To read the values from the Inverter the ESP32 communicates via RS485 transreceiver.

Sends over CAN bus to inverter:

  • Battery Voltage
  • Battery Current (+charge, -discharge)
  • State of Charge (SOC)
  • State of health (SOH)
  • BMS Temperature
  • Charging Voltage
  • Charging Amps
  • Discharge min Voltage
  • Battery name
  • Alarms: Cell over/under voltage, Charge/discharge over current, High/low Temp, BMS fault
  • Charging logic: Complete rework of the charging logic, now charges with constant current(CC) to the absorption voltage, then has an absorption timer (Constant Voltage, user configurable time), with rebulk feature (user configurable offset from absorption voltage).

Home Assistant native integration via ESPHome:

  • Controls to manage inverter remotely
    • Set "Balance Voltage" to tell inverter to only charge till this voltage
    • Set "Min Discharge Voltage" to tell inverter stop discharging below this voltage
    • Set "Charging Current"
    • Set "Discharging Current"
    • Disable/Enable inverter charging
    • Disable/Enable inverter discharging
    • Disable/Enable top balance charging
    • Set "Days Bewteen Balancing" to only balance every x days, in between it will stop charging when "Max Charge %" is reached
    • Set "Max Charge %" for days in between top balance cycles (on top balance days it will charge till "Balance Voltage")
    • Set "Min Discharge %" to stop discharging

Supported devices

Inverters supporting CAN Pylon/Goodwe Low Voltage protocol should work, check your inverter manual to confirm.

The following are confirmed and known to work:

  • Deye SUN-12K-SG04LP3-EU


All JK-BMS models with software version >=6.0 are using the implemented protocol and should be supported.

Requirements

  • ESPHome 2022.11.0 or higher.
  • Optimized for ESP32-S2 because of lower power consumption but works with Generic ESP32 as well
  • TJA1050 CAN controller interface module and 4.7K resistor for 5v to 3.3v level shifing.
  • Optional: JK RS485 Adaptor and RS484 to TTL3.3v Adaptor (see optional schematic below)

Schematics

I have designed and build a PCB pictured below. This has all the hardware needed to communicate with BMS and Inverter via CAN bus and Modbus. It is a plug and play device, just connect the 4 pin headder in the BMS and a LAN cable to the Inverter.

Optional below, as seen in pic above: RS485 between JK-BMS GPS port and ESP32-S2 Wemos Mini, uses JK RS485 adaptor and RS485 to TTL3.3v adaptor.

The RS485-TTL jack of the BMS can be attached to any UART pins of the ESP. A hardware UART should be preferred because of the high baudrate (115200 baud). The connector is called 4 Pin JST with 1.25mm pitch.

Installation

You can install this component with ESPHome external components feature like this:

external_components:
  - source: github://Ackmaniac/esphome-jk-bms-can@main

or just use the esp32-example-can-deye-modbus_espidf.yaml as proof of concept:

# Install esphome
pip3 install esphome

# Clone this external component
git clone https://github://Ackmaniac/esphome-jk-bms-can.git
cd esphome-jk-bms-can

# Create a secrets.yaml containing some setup specific secrets
cat > secrets.yaml <<EOF

Known issues

  • The battery type sensor is pretty useless because the BMS reports always the same value (Ternary Lithium). Regardless of which battery type was set / parameter set was loaded via the android app. (#9)
  • ESP32: Adding all supported sensors can lead to a stack overflow / boot loop. This can be solved by increasing the stack size. (#63)

Debugging

If this component doesn't work out of the box for your device please update your configuration to enable the debug output of the UART component and increase the log level to the see outgoing and incoming serial traffic:

logger:
  level: DEBUG

uart:
  id: uart0
  baud_rate: 115200
  rx_buffer_size: 384
  tx_pin: GPIO14
  rx_pin: GPIO4
  debug:
    direction: BOTH
