Caution

Working with high voltage is dangerous. Always follow local laws and regulations regarding high voltage work. If you are unsure about the rules in your country, consult a licensed electrician for more information.

Compatible Afore Inverters

  • AF17K-THA 230V ☑️ (Works with BYD_CAN or AFORE_CAN)
    • Depending on software version, you might need to do an inverter firwmare update to get the BYD CAN option

Communication wiring

The Afore inverter works via CAN. The LilyGo board can have both a CAN battery and a CAN inverter connected on the same pins. When the board is used with two CAN devices at the same time that have termination resistors in all ends, the terminating resistor needs to be removed from the board. Please measure CAN termination if you have issues. This is explained in CAN-troubleshooting

ℹ️ Always check the termination resistance of the system! That way you know if resistor needs to be removed or not.

ℹ️ Grounding is extremely important. Make sure the battery case is connected to protective earth, and the shield part of the twisted pair CAN is connected to PE also! Failing to do this will result in CAN errors.

Compiling the software for Afore inverters

Make sure that the settings in the "USER_SETTINGS.h" file are correct. The line:

#define BYD_CAN //Enable this line to emulate a "BYD Battery-Box Premium HVS" over CAN Bus

Needs to be uncommented for the software to emulate the BYD protocol over CAN. Next step is then to select the battery that you intend to use, for instance if you use LEAF battery, make sure the following line is uncommented:

#define BATTERY_TYPE_LEAF // See NISSAN-LEAF-BATTERY.h for more LEAF battery settings

After setting this up, flash the board!
