Inverter: Growatt LV
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.

The Growatt LV compatible inverters 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.
Make sure that the settings in the "USER_SETTINGS.h" file are correct. The line:
//#define GROWATT_LV_CAN //Enable this line to emulate a "48V Growatt Low Voltage battery" over CAN bus
Needs to be uncommented for the software to emulate the correct protocol.
