The BLUETTI EP2000 system can be configured with one EP2000 inverter, one HV800 controller, and a varying number of B700 batteries from 2 to 7. The stacking arrangement varies with the number of batteries:

• 1 EP2000 + 1 HV800 + 2 B700: Single stack.

• 1 EP2000 + 1 HV800 + 3 B700: Single stack.

• 1 EP2000 + 1 HV800 + 4 B700: Two stacks. Left stack: EP2000, HV800, B700, B700. Right stack: B700, B700.

• 1 EP2000 + 1 HV800 + 5 B700: Two stacks. Left stack: EP2000, HV800, B700, B700. Right stack: B700, B700, B700.

• 1 EP2000 + 1 HV800 + 6 B700: Two stacks, with 3 B700 batteries on the left side and 3 B700 batteries on the right side.

• 1 EP2000 + 1 HV800 + 7 B700: Two stacks. The left stack contains the EP2000, HV800 and multiple B700s, and the right stack contains the remaining B700s.

Use a 10mm² yellow-green grounding cable. Connect the ground cables for the EP2000 inverter and the HV800 controller to the corresponding grounding terminals (marked PE). The connection is made on the left side of the stacked units. Ensure the wire is properly stripped and secured in the terminal block. The stripped wire end (L2) should be 3mm longer than the insulation (L1). The visible wire should be even or bulge up to 1 mm in the terminal lug. The right side of the stack is grounded through the inter-unit connections.

The batteries in the BLUETTI EP2000 system are connected in series. For example, in a system with an EP2000, HV800, and 2 B700 batteries, the power cables are connected as follows:

1. Connect the (EP2000) BAT+ cable to the corresponding (HV800) P+ terminal.

2. Connect the (EP2000) BAT- cable to the corresponding (HV800) P- terminal.

3. The power connections between the HV800 and the B700 batteries, and between the B700 batteries themselves, are made through their respective BAT+/BAT- and AC INPUT/OUTPUT ports as shown in the electrical connection diagrams.

Connect the communication cable from the COM1 port on the BLUETTI EP2000 inverter to the PCS1 port on the HV800 Battery Controller. This is done on the left side of the unit. Communication between other units like the B700 batteries is handled via Pack LINK cables on the right side.

The AC power cables link the HV800 Battery Controller to the B700 batteries. Connect the AC OUTPUT cable from the HV800 to the AC INPUT of the first B700 battery. Then, connect the AC OUTPUT of the first B700 to the AC INPUT of the second B700, and so on, creating a daisy chain.

1. Use a 5-core 10mm² copper power cable. The maximum current is 50A for installation in an electrical conduit and 60A for installation in air.

2. Connect the L1, L2, L3, N, and PE wires for both the GRID input and the BACKUP output to the corresponding terminal blocks on the BLUETTI EP2000 inverter.

3. When connecting these cables, do not use electric tools. Use a manual H3 hex screwdriver to tighten the locking screws. The recommended torque is 2 Nm.

The transfer switch is used to switch your essential loads between the public grid and the BLUETTI EP2000 backup power.

Connection:

1. Connect the L1/L2/L3/N wires from the BLUETTI EP2000 BACKUP terminal and the Public Grid to the top side of the transfer switch.

2. Connect the essential loads to the bottom side of the transfer switch.

3. The neutral cable from the BACKUP terminal of the EP2000 cannot be connected to the neutral cable of the public grid.

The wiring connections are as follows:

Operation:

• Position “I” (ON): Use this position when the grid is stable. The BLUETTI EP2000 and public grid will power the loads. If the EP2000 ESS fails, you can still use the utility grid by turning the switch to “I”.

• Position “II” (ON): Use this position during a power outage. The EP2000 will power the essential loads in Backup mode.

• Position “OFF”: Disconnects the loads.

Connecting PV (solar panel) cables to the BLUETTI EP2000 involves preparing the cables and connecting them to the correct terminals.

Cable Preparation and Connection:

1. Use cables with a cross-sectional area of 2.5-4mm².

2. Strip the ends of the positive and negative wires (about 7-9mm).

3. Crimp the positive and negative metal cores onto the corresponding wires using crimping pliers.

4. Assemble the MC4 connectors, ensuring the positive and negative connectors are correctly placed.

5. Tighten the connectors using an MC4 wrench.

Terminal Assignment:

The BLUETTI EP2000 has four PV inputs (PV1, PV2, PV3, PV4). For each input:

• PE: Connects to the Solar panel ground.

• PV+: Connects to the solar panel positive wire.

• PV-: Connects to the solar panel negative wire.

Important Note: Please check the open circuit voltage of the PV arrays, which should be between 240V and 1000V.

The Energy Management System (EMS) controller must be installed and connected to the BLUETTI EP2000 for system monitoring and control.

Installation:

1. Drill holes in the wall using the provided dimensions (136 mm apart horizontally, 663.8 mm apart vertically).

2. Insert expansion plugs into the holes.

3. Secure the mounting bracket to the wall with self-tapping screws.

4. Mount the EMS Controller onto the bracket and secure it with the fixing screw.

Connection:

1. Connect the EMS communication cable to the COM2 port on the BLUETTI EP2000 inverter.

2. The EMS also communicates with the grid meter via RS485. The connections are as follows:

Note: Make sure the router is set to IEEE 802.11 b/g/n 2.4GHz for wireless communication.

To connect the grid meter (METER) to your BLUETTI EP2000 system, follow these steps:

1. The Current Transformers (CTs) must be installed with the arrow inside the CT pointing towards the grid.

2. Ensure the correct phase sequence: connect the CT on grid line L1 to the meter’s GRID-L1 input, L2 to GRID-L2, and L3 to GRID-L3.

3. The CTs should be tied to the L1, L2, and L3 cables of the main circuit breaker of the grid.

4. For the communication cable between the meter and the EMS controller, connect the red wire (pin 4) to pin A on the meter and the black wire (pin 3) to pin B on the meter. Use a shielded twisted pair cable.

The BLUETTI EP2000 supports several application scenarios:

• DC coupling: Solar panels (PV) are directly connected to the EP2000’s DC inputs. The system manages power from the grid, PV, and the B700 battery to supply loads connected to a sub-panel.

• AC Coupling: An existing grid-tied PV system with its own PV inverter is connected to the main panel. The BLUETTI EP2000 is also connected to the main panel and provides backup power from the B700 battery to loads on a sub-panel.

• AC + DC Coupling: This is a hybrid setup that combines both DC-coupled solar panels connected directly to the EP2000 and an existing AC-coupled PV inverter system.

For a new solar panel installation connected in DC coupling mode with the BLUETTI EP2000, please note the following:

• Cables: Grid and Backup electric cables are recommended to be 10 mm² (AWG 6#).

• Grounding: In Australia, New Zealand, and South Africa, N and PE are connected together in the power distribution box. In this case, the PE of the BACKUP port of the EP2000 does not need to be connected.

• 1. Photovoltaic Inputs: The system has four inputs (PV1, PV2, PV3, PV4), with a maximum power of 9 kWp each.

• 2. MPPT Configuration:

– PV1 & PV2 share one MPPT; PV3 & PV4 share another.

– Each MPPT supports up to two strings, with a total maximum current of 30A, and each string up to 20A.

• 3. Y-Type Connectors:

– For photovoltaic arrays that are connected in parallel, Y-type connectors need to be selected.

– The parallel photovoltaic arrays must ensure the following consistency: same model, same number of panels, same tilt angle, same orientation angle.

For an existing solar roof connected in AC coupling mode with the BLUETTI EP2000, please note the following:

• Cables: Grid and Backup electric cables are recommended to be 10 mm² (AWG 6#).

• Grounding: In Australia, New Zealand, and South Africa, N and PE are connected together in the power distribution box. In this case, the PE of the BACKUP port of the EP2000 does not need to be connected.

• 1. Photovoltaic Inputs: The system has four inputs (PV1, PV2, PV3, PV4), with a maximum power of 9 kWp each (if used).

• 2. MPPT Configuration:

– PV1 & PV2 share one MPPT; PV3 & PV4 share another.

– Each MPPT supports up to two strings, with a total maximum current of 30A, and each string up to 20A.

• 3. Y-Type Connectors:

– For photovoltaic arrays that are connected in parallel, Y-type connectors need to be selected.

– The parallel photovoltaic arrays must ensure the following consistency: same model, same number of panels, same tilt angle, same orientation angle.

Beyond standard coupling, the BLUETTI EP2000 can be used in these scenarios:

• Backup power: The EP2000 is connected to the main panel and provides backup power from the B700 battery to essential loads on a sub-panel during a grid outage. It does not use solar input in this configuration.

• Off-grid: The EP2000 and B700 battery are charged by solar panels (PV) to power loads on a sub-panel completely independently of the utility grid.

• Parallel connection on the backup side: Two EP2000 systems can be connected in parallel to increase power output. Each system can have its own PV input and battery storage, and they work together to power the loads on a sub-panel.

• Integration with Manual Diesel Generator: A fuel generator can be integrated into the system as an additional power source for charging the battery and powering loads via the main panel, alongside the grid and PV input.

Follow these steps to safely power on your BLUETTI EP2000 system:

Step 1: Switch on the PV input switch on the EP2000 inverter.

Step 2: Switch the circuit breaker on the HV800 to “ON”. Press and hold the power button on the HV800 till the indicator on the button lights up green.

Step 3: Wait about 40 seconds for the inverter indicator to stay steady green.

Step 4: Switch on the AC circuit breakers for the inverter’s GRID block.

Step 5: Turn on “System Switch” in the BLUETTI app.

Step 6: Check the output voltage of the BACKUP block.

Step 7: Switch on the AC circuit breakers for the inverter’s BACKUP block.

Step 8: Monitor EP2000 system status using the BLUETTI app.
