Operation

Sub Panel supports manual bypass conversion function for maintenance, When you want to remove the EP500/Pro, AC300 Power Station from the Sub Panel, please tweak the rotary switch on Sub Panel to “2” (Figure 4.3) to maintenance then disconnect the connecting cable on Power Station,-the household load will be powered directly by the utility power.
4.1 Pass-through Function
Rotary Switch Status: “O”: Disconnect. Loads on Sub Panel are disconnected from both the utility power and Power Station. (Figure 4.1)
“1”: Connected. Sub Panel functions are all enabled. (Figure 4.2)
“2”: Grid power supply. The grid power supply status bit is directly supplied by the grid household load, which can complete the charging function for matching products.(Figure 43)
4.2 Grounding Method
FLOATING NEUTRAL: When Sub Panel is connecting with BLUETTI Power Station only(Disconnected with Main Panel): AC300, EP500, and EP500Pro, the N and PE Wire of the Input Port and Output Port of Power Station are not connected to Sub Panel directly, the distribution system’s neutral conductor will “float”, which means they are floating neutral.
BONDED NEUTRAL: Connecting the Sub Panel to BLUETTI Power Station will not switch the floating neutral to bonded neutral. If you want to convert the Sub Panel to bonded neutral, please connect the Sub Panel with Main Panel, or follow the instruction to connect the Neutral bus bar to PE.
Connect AC1 and LOAD1 to one device, and AC2 and LOAD2 to another device.
