NOTE:
1. The arrow inside the CT points to the grid.
2. Phase sequence: L1 to R, L2 to S, L3 to T.
3. The CT should be tied to the L1, L2 and L3 cables of the
main circuit breaker of the grid.
3.7 Attach the CT 3.9 Electrical connection mode 1: DC coupling 3.10 Electrical connection mode 2: AC coupling
3.8 Install the transfer switch
NOTE:
1.The neutral cable from the BACKUP teminal of EP600 cannot
be connected to the neutral cable of the public grid.
2.Connect the L1/L2/L3/N wires from EP600 BACKUP terminal
and public grid to the input side of the transfer switch, and the
output side to the essential loads.
3.If the grid is stable, turn to “II” to use the public grid to
power the loads; otherwise turn to “I” to use EP600 UPS
mode to avoid the inconvenience caused by power outage.
4.If EP600 ESS fails, turn to “II” and contact BLUETTI
Customer Support.
NOTE:
The meter is for EP600 ESS with grid-tied
PV inverter only.
1) Connect UA/UB/UC/UN cables to the
L1/L2/L3/N of PV inverter.
2) Connect the CT to the Meter and tie
them to L1/L2/L3 cables of the PV inverter.
3) Connect the 485-A red wire to pin 21,
485-B black wire to pin 22.
Step 1 Switch on the DC circuit breakers on EP600.
Step 2 Switch on the DC circuit breakers on B500 battery packs. Press and hold the power button of any
battery pack for about 3 seconds, and the green indicator on the button will light up.
Step 3 About 40 seconds later, the indicator on EP600 will stay green.
Step 4 Switch on the AC circuit breakers connected to the EP600 GRID terminal.
Step 5 Power on the system via BLUETTI app.
Step 6 Check the voltage of BACKUP terminal.
Step 7 Switch on the AC circuit breakers connected to the EP600 load port.
Step 8 Check the EP600 system operation in the App.
