What are the requirements for battery connection in the X1-VAST series inverter?

The inverter supports two independent battery terminals. The input voltage of each BAT terminal should be higher than 80 V and lower than 480 V. If two string batteries are connected separately, the maximum charge/discharge current of each battery is 25A; if one string battery is connected to one port, it's 30A. A non - polar DC MCB may be required according to local regulations.
