Supported Grid Types:

The inverter supports TN-S, TN-C, TN-C-S, and TT grid types.

System Operation

Turning the System ON:

For configured PV module:

1. Set BATTERY SWITCH to ON.
2. Turn on the AC switch between the inverter and the grid.
3. Set PV SWITCH to ON.
4. Observe the LED indicator for system status.

For unconfigured PV module:

1. Set BATTERY SWITCH to ON.
2. Turn on the AC switch between the inverter and the grid.
3. Set PV SWITCH to ON.
4. Press and hold the BATTERY ON/OFF button for three seconds after startup.
5. Observe the LED indicator for system status.

Turning the System OFF:

1. Tap the shutdown command in the app.
2. Turn off the AC switch between the inverter and the grid.
3. Set PV SWITCH to OFF.
4. (Optional) Secure the PV SWITCH with a padlock.
5. Set BATTERY SWITCH to OFF.
6. (Optional) Secure the BATTERY SWITCH with a padlock.
7. Press and hold the BATTERY ON/OFF button for 10 seconds until the indicator turns off.

Downloading the App:

Download the EcoFlow app for home or installer use. Scan the QR codes or visit the provided links.

Operating Modes:

• Shutdown Mode: No internal power, inverter, or battery DC-DC converter is operating.
• Standby Mode: Internal auxiliary power is on, but inverter and battery DC-DC converter are off.
• Self-test Mode: Internal auxiliary power is on, inverter and battery DC-DC converter are off. System enters self-test upon receiving a power-on command.
• Operation Mode: Internal auxiliary power, inverter, and battery DC-DC converter are operating. The inverter converts DC to AC power.

Backup Power Function:

The inverter creates a backup power supply using battery and PV energy during grid outages. This function is enabled by default.

• During a grid outage, backup loads connected to AC-BACKUP are powered by the battery and PV system.
• Batteries are charged by the PV system during backup operation if sufficient energy is available.
• When grid power is restored, the backup power function is automatically disabled, and loads are powered by the grid.
• Switching time to backup power is typically less than 20 ms.

Backup Power Overload Protection:

The inverter may restart automatically after an overload. If the situation repeats, the restart time will be extended. Try disconnecting loads with high inrush currents.

Optimizing Solar Energy in Shaded Conditions:

This feature, disabled by default, optimizes solar energy generation in shaded conditions. Enable it during system commissioning via the EcoFlow Pro app.

RCR or DRM Detection:

The inverter supports Ripple Control Receiver (RCR) and Demand Response Mode (DRM) for grid interaction as required in certain regions. This function is enabled by default.

Custom Parameters:

Customizable parameters for connection, voltage protection, frequency protection, and reactive power can be set via the EcoFlow Pro app during commissioning.

Maintenance and System Replacement

Routine Maintenance:
