Inverter Bus voltage?

Solar Inverters

Hello All,

I have a SAJ Suntrio Plus 5K inverter with 12pcs Longi LR6-60HPH-325M solar panel on one string.
The inverter shows the below voltages:
Bus Voltage 632V
PV1 Voltage 373V
The PV1 voltage is clear.
But could you please tell me what is “Bus voltage” and how it is calculated?

I’m not sure what the Bus voltage is referring to, but I assume it’s the internal DC high-frequency conversion voltage.
Is the inverter functioning normally? Are you just curious about this voltage?
