BLUETTI EP600 Energy Storage System Installation SOP

1. Declaration

• The installation should be performed by a licensed electrician. Improper installation may result in death or serious injury and property damage.
• This document is provided for reference purpose ONLY and does not constitute legal advice. Please consult the local licensed electrician for details.
• BLUETTI shall not be liable for any damage or injury caused by improper installation of the backup system.

2. EP600 Energy Storage System Introduction

The EP600 Energy Storage System (ESS) consists of the EP600 inverter, B500 batteries, and an IoT controller. It connects to solar panels (PV), the grid, and AC loads. The system can be monitored and controlled via the BLUETTI App using Wi-Fi or Bluetooth.

2.1 Electrical Connection Modes: DC Coupling

This mode involves direct connection between the PV system and the EP600 inverter. The diagram shows PV input, battery connection, grid connection, and output to Normal Load and Essential Load.

2.2 Electrical Connection Modes: AC Coupling

This mode is used when a separate PV inverter is present. A meter is required in this setup. The diagram illustrates the connection of a user's PV inverter to the EP600, along with grid and load connections.

2.3 Electrical Connection Mode 3: AC/DC Coupling

This mode combines aspects of both AC and DC coupling. The diagram shows connections for PV, a user's PV inverter, the EP600, battery, grid, and loads.

NOTES:

• For single-phase household appliances with power larger than 2000W or three-phase loads with a total power larger than 6000W (e.g., embedded induction cookers, air conditioners), they need to be connected to the grid.
• The energy management system can intelligently output single-phase 2000W or three-phase 6000W electric energy to household appliances. The remaining power is supplied by the power grid to reduce electricity costs.
• Single-phase loads with power greater than 2000W should not be connected to the BACKUP terminal.

4.11 Connecting to the Main Panel

4.11.1 Find out the essential household appliances

NOTE:

• Before installing the EP600 energy storage system, consider whether to make a partial backup system. If power outages are frequent, a backup system is recommended.
• Ensure the total rated power of essential appliances connected to the BACKUP of EP600 (e.g., fridge, lights) is less than 2000W per phase for a three-phase system (less than 6000W total).

NOTE: Other high-power appliances must be connected to the public grid.

4.11.2 Create a plan for the essential backup appliances

Plan for essential appliances like refrigerators and lights. The EP600 can output 2000VA per phase or 6000VA for three phases. Allocate circuit breakers accordingly.

Load Balancing Example:

Circuit Breaker Connections: Three 230V single pole circuit breakers, or one three-pole circuit breaker.

Total essential running Watts Phase One: <2000W

Total running Watts Phase Two: <2000W

Total running Watts Phase Three: <2000W

It's OK!

4.11.3 Connect Meter Communication Cables

Connect the meter communication cables to the COM Port of the EP600. The meter is applicable only when PV grid-tied inverters are installed.

• Connect the cables of UA, UB, UC, UN to the L1/L2/L3/N of the PV inverter.
• Connect the cables of the CT to the meter and the wires of L1/L2/L3 of the PV inverter.
• Connect the 485-A red wire to pin 21 and the 485-B black wire to pin 22.

4.11.4 Transfer Switch Circuit Connection

4.11.4.1 About Transfer Switch

The transfer switch is essential for building a partial residential backup system.

NOTES:

• Before installing the EP600, read the following notes carefully:
• Switch to 'I' means the electrical power is from the EP600. Owners can switch to 'I' until faults occur to EP600.
• When faults occur to EP600, switch to 'II' to use the public grid.
• If the public power grid is always out of power, switch to 'I' to use EP600 UPS mode; otherwise, switch to 'II'.

4.11.4.2 How to connect the transfer switch to the residential circuit

This section provides an example of a residential circuit before EP600 installation and then details the connection of the EP600 and transfer switch to the residential circuit.

NOTES:

• Connect the L1/L2/L3/N wires from EP600 BACKUP to pin 2(L1), pin 6(L2), pin 10(L3), pin 14(N) of the transfer switch.
• Connect the L1/L2/L3/N wires from the public grid to pin 4(L1), pin 8(L2), pin 12(L3), pin 16(N) of the transfer switch.
• Move the wires of the circuit breaker connected to essential appliances, then connect pin 1(L1), pin 5(L2), pin 9(L3), pin 13(N) of the transfer switch.
• The CT is used for detecting the current. Refer to the installation video for details.

4.11.5 Installing the CT to grid power cables

• The arrow inside the CT points to the grid.
• Pay attention to the phase sequence: L1 to R, L2 to S, L3 to T.

4.11.6 Turn on the transfer switch

Step 1: Turn the transfer switch to position II. The current flows from the Grid to the loads.

Step 2: Turn the transfer switch to position I. The current flows from the Backup port of EP600 to the loads.

5. Powering on the ESS

• Step 1: Switch on the DC circuit breakers on B500 battery packs. Press and hold the power button of any battery pack for 3 seconds until the green indicator lights up.
• Step 2: Wait for 40 seconds until the green indicator of the inverter is always on.
• Step 3: When connecting to the solar panel, switch on the DC circuit breakers on EP600.
• Step 4: Switch on the AC circuit breakers connected to the EP600 grid port.
• Step 5: Power on the system via the BLUETTI app.

6. Using BLUETTI App

The BLUETTI App allows you to monitor and control the EP600 energy storage system (ESS) via Bluetooth or Wi-Fi. Features include Real-time Alarm, Error Message, Data Collection, Operation Status, Parameter Configuration, and Firmware Upgrade.

Note:

• Apply to operating systems: Android 8.0 or above, iOS 11.0 or above.
• Bluetooth is available on your phone.
• Router requirement: WiFi IEEE 802.11 b/g/n, 2.4GHz. Turn off the 5G option.
