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?
The “bus voltage” in your SAJ Suntrio Plus 5K inverter refers to the voltage level of the DC bus, which is essentially the electrical backbone that connects your solar panels to the inverter. It’s like the main highway where electricity flows from your panels to the inverter.
This voltage is calculated based on the combined voltage of all the panels in your array. It’s crucial for the inverter to efficiently convert the DC power from the panels into AC power for your home or the grid.
In simpler terms, think of the bus voltage as the overall energy highway guiding power from your panels to where it’s needed. It ensures smooth and reliable operation of your solar system.
