== Overview ==

Variable Frequency Drives (VFDs) made by Changsha Best Electrical Technology Co.,Ltd. Unfortunately they lack Modbus/RS-485 support.

== Model Numbers ==

* [https://salecnc.com/manuals/Inverter/BEST-FC300_English.pdf#page=2 Page 2] (1 in the PDF) shows the model number breakdown.

The first field would be "FC300" for the general model number.

The second field is the kW rating of the VFD, such as "2.2" for 2.2kW.

The third field is a combination of the letter "S" or "T" for single-phase and three-phase, and a number such as "2" or "4" for 200V and 400V, which usually really mean 220V and 380V.
