Huawei SUN2000 MAP0 Series - F Baud Rate Negotiation

F Baud Rate Negotiation
Baud rate negotiation increases the communications rate between the inverter
and devices such as batteries and power meters, and between the inverter and
devices such as the Smart Dongles and the EMMA, solving or relieving
communication congestion.
● During device search in a new plant, the system automatically negotiates the
baud rate.
● When replacing or adding inverters, batteries, power meters, the Smart
Dongle, or the EMMA at an existing plant, you need to manually send local
commands on the FusionSolar app to reset the baud rate between devices
and negotiate a higher rate.
NO TE
Users can send the baud rate negotiation commands on the FusionSolar app in two
networking modes: EMMA networking and Smart Dongle networking.
