BLUETTI EP900 (01) PDF DOCUMENT

The BLUETTI EP900 EMS controller offers the following features:

• Control and monitor one or multiple inverters remotely from anywhere.

• Intelligently balance loads, optimize battery usage, and make the most of solar energy across multiple inverters.

• A touchscreen to operate in a visual manner.

The homepage of the BLUETTI EP900 provides an overview of the system status:

1. Date & time: Displays the current date and time.

2. Connection Status: Shows icons for WiFi connection and Bluetooth connection.

3. Energy Flow: A visual representation of the Energy Storage System (ESS). This shows production, consumption, grid interaction, and battery state of charge.

4. Homepage Button: An icon to return to the homepage.

5. Settings: An icon to check and change system settings like System Switch, Working Mode, Network Settings, Advanced Settings, etc.

6. Alarms: An icon to check current alarm(s) and alarm history. The icon turns red in case of an alarm.

The animation on the BLUETTI EP900 homepage gives you a simple way to understand how energy is flowing:

• SoC (State of Charge): The percentage shown in the central circle indicates the remaining battery level.

• PV generation: This icon shows how much power the ESS is drawing from your rooftop solar or solar panel(s). You can tap it to view more details.

• Grid charging or feeding: This icon shows how much power the ESS is drawing from or feeding back into the grid. You can tap it to view more details.

• Load consumption: This icon shows how much power is being supplied to your household appliances. You can tap to learn more about where the power is going.

After connecting the device, tap the settings icon (gears) on the right side of the homepage to access the Setting page. From here, you can optimize your power usage by customizing various settings.

• System Switch: This is the main switch of the ESS. Keep it on if you want the ESS to charge and discharge. If it’s off, the system is in standby mode with no input or output. Note: If you’re connecting cables or not using the system, turn the System Switch off.

• Network Settings: Choose Bluetooth or WiFi for connecting your mobile device.

The following basic settings can be configured on your BLUETTI EP900:

• Working Mode: Tap to set the working modes. Please refer to the specific working modes for details.

• Date and Time Settings: To set the date and time.

• Buzzer Switch: Enable to sound an alarm when the device encounters hardware faults.

• Proximity Sensor: The screen lights up as someone approaches when it’s enabled.

• Touch Sounds: Enable for a sound response during interface operation.

• Brightness: Slide to adjust the screen brightness.

• Auto Sleep: Choose screen sleep time (30s, 1min, 5min, always on). The default screen sleep time is 1 minute.

• Language: To select system language: English, German, or Japanese.

• Advanced Setting: To check and change more settings.

• Disaster Alert: With the switch on, the ESS switches to Backup Mode upon receiving a disaster alert and returns to the previous mode after the alert concludes.

The advanced settings on the BLUETTI EP900 EMS controller include:

• Grid Self-adaption: Enable it when the ESS connects to an unstable grid with voltage fluctuations, low voltage, high voltage, etc. Once enabled, when charging from the grid, the charging power will gradually increase to minimize the impact on the grid.

• System Switch Recovery: To save the system switch status and restore it on restart.

• About Device: The information about the EMS controller.

• Reset: To reset all settings to default.

The BLUETTI EP900 EMS controller allows configuration for three modes: Backup, Self-consumption, and Scheduled Charge & Discharge (Time of Use). To select a mode:

1. Tap Working Mode on the Setting page.

2. Tap Working Mode again.

3. Tap the left or right arrows to switch between the working modes.

4. Tap Confirm.

Note: To set parameters for the Time of Use mode, tap Confirm, and then tap the settings icon to adjust relevant parameters.

The Backup mode on the BLUETTI EP900 is suitable for areas with an unreliable power grid. In this mode, the system acts as a reliable backup power source that only activates when the grid fails. The ESS charges its batteries to full from both the grid and solar, giving priority to solar energy. With ample solar and grid energy, 100% of your energy is reserved for backup, ensuring uninterrupted power whenever needed.

The Self-consumption mode on the BLUETTI EP900 is suitable for areas with abundant solar resources and a stable power grid. In this mode, the system prioritizes direct solar energy consumption for household needs. Any surplus energy is intelligently stored in the battery for peak hours or power outages.

The Time of Use mode on the BLUETTI EP900 is suitable for areas with fluctuating electricity prices. During peak electricity pricing, the ESS provides power to household appliances. During off-peak times when electricity rates are lowest, it draws power from the grid to charge the battery. In this mode, you can set an SoC High value and a specific charge/discharge schedule to optimize cost savings.

1. Set SoC High:

In the Time of Use settings, you can configure the SoC High value. The ESS will stop charging from the grid when the battery level reaches the configured SoC and will seamlessly switch to solar charging for the remaining capacity.

2. Manage Charge/Discharge Time:

a. Tap Scheduled Manage Charge/Discharge Time.

b. Tap OK in the Attention pop-up.

c. Specify a period, and set it as an Off-peak or Peak period.

• Off-Peak: Schedule the ESS to charge during off-peak hours when electricity costs are lower.

• Peak: Schedule the ESS to discharge during peak hours when electricity costs are higher.

• Middle: Disable the power supply from the battery to the load.

You can charge your BLUETTI EP900 ESS from the grid using Scheduled Charging. Note: Disable the System Switch before setting working modes.

1. Tap Working Mode on the Setting page.

2. Tap Working Mode again.

3. Tap the left or right arrows to switch to the Time of Use mode, and tap Confirm.

4. Tap the settings icon to enter the parameters settings.

5. Tap Scheduled Manage Charge/Discharge Time.

6. Tap OK in the Attention pop-up.

7. Specify a period, and set it as an Off-Peak period.

Other options include using Backup mode or Custom mode (configured via the BLUETTI App).

With this setup, you can offset your energy usage during peak hours but are unable to sell any extra energy back to the grid. To schedule the BLUETTI EP900 to charge during off-peak hours and supply power during peak hours:

1. Tap Working Mode on the Setting page.

2. Tap Working Mode again.

3. Tap the left or right arrows to switch to the Time of Use mode, and tap Confirm.

4. Tap the settings icon to enter the parameters interface.

5. Tap Scheduled Manage Charge/Discharge Time.

6. Tap OK in the Attention pop-up.

7. Choose a time period when electricity prices are lower. Set it as an Off-Peak period. And set Peak periods during times when electricity prices are higher.

This mode is suitable for areas with abundant solar resources. Switch on the PV switch of the inverter and check for a successful solar input. Turn on the System Switch on the Setting page; the system automatically prioritizes solar energy to supply the load and charge the battery.

If you want to rely less on the grid:

1. Tap Working Mode on the Setting page.

2. Tap Working Mode again.

3. Tap the left or right arrows to switch to the Self-consumption mode, and tap OK.

The BLUETTI EP900 ESS can be used as a backup power supply for emergencies, especially in areas with an unstable grid. To set it up:

1. Tap Working Mode on the Setting page.

2. Tap Working Mode again.

3. Tap the left or right arrows to switch to the Backup mode, and tap OK.
