Growatt Inverters

Growatt inverters are accessed using a Serial Port connection (e.g. COM3).

PVBC can access multiple Growatt inverters simultaneously. When the inverters are connected in an RS485 daisy chain, these inverters can be accessed via a single serial port, otherwise you require a separate serial port for each Growatt inverter. 

Growatt inverters can use .the proprietary Growatt protocol. Some Growatt inverters can also use the ModBus protocol. Devices of different types and manufacture that use the ModBus protocol can be accessed via a single serial port when connected in an RS485 daisy chain.
