Operation Mode

The PowerOcean Plus energy storage system can work in shutdown, standby, self-check or operating mode.

Shutdown mode: Insufficient power from PV string, power outage, battery level: 0%

Standby mode: Sufficient power from PV string (system restarts automatically), grid power detected, battery switch turned on

Self-check mode: Fault detected, Shutdown command from app, self-check failure; Power-on command detected; Self-check passed

Operating mode: Fault detected, Shutdown command from app; Self-check passed; Fault detected, Shutdown command from app

Back-Up Function

[CAUTION] For hybrid inverters, both PV modules and batteries need to be configured in the system installation typically and there is sufficient power from batteries or PV modules in backup mode, otherwise, the backup power supply will be automatically terminated. EcoFlow shall hold no liability for any consequences arising from failing to observe this instruction.

[NOTICE] To prevent the power backup function from failing, instructions as below must be observed:

• The system is not suitable for powering life-sustaining medical devices. It cannot guarantee backup power in all circumstances.
• Do not connect any loads that require an uninterrupted energy supply.
• Do not connect the loads whose total capacity is greater than the maximum Back-Up capacity.

The backup function ensures that the inverter forms a three-phase battery-backup grid that uses energy from the battery and the PV system that is directly connected to the inverter to power the household loads in the event of a utility grid outage. The backup function is enabled by default.

When a utility grid outage occurs: The backup loads connected to the AC-BACKUP terminal are connected and supplied to the AC-GRID terminal via an integrated bypass contactor. The contactor opens when a utility grid outage occurs. The backup loads are switched to be supplied by the energy stored in the battery and the PV modules connected directly to the inverter.

Batteries keep being charged by the existing PV system during backup operation.

However, the inverter is able to create a stable battery-backup grid only when sufficient power is available in the battery. Battery-backup operation starts automatically when sufficient energy is available from the PV system.

Utility grid recovers: The backup operation is disabled automatically and the loads are supplied with energy from the power grid and PV system.

Backup switching time: Under normal circumstances, the back up switching time during grid outage is less than 20 ms, which will be more than 20ms when low-voltage ride-through function is enabled by default based on local electrical code.

You can set charging and discharging limit in the EcoFlow app.

Back-Up Overload Protection

When single overload protection occurs, the inverter can restart automatically. However, the restarting time will be extended (5 min at most) if it repeats. For a faster restarting, try it via app. Try removing the loads which may cause very high start-up current surges.

Optimize Solar Against Shade

The system will optimize solar generation in shaded conditions at your setup intervals to track the maximum power point. Solar generation may fluctuate under this condition.

This Function is disabled by default. To enable it, switch on Commissioning > Optional setup > Optimize solar generation in the EcoFlow Pro app when the installer performs system commissioning.

RCR or DRM Detection

Ripple control receiver (RCR) is an interface between a PV system and power grid company that enables the grid operator to reduce the feed-in power, required in Germany and some European regions for more than 25kW inverters. Demand Response Mode (DRM) which enables the inverter to respond to signals sent to it remotely, is required in Australia. Generally, if the grid is overloaded, the utility company will specify whether the PV system should reduce the feed-in power to 0%, 30%, 60% of the rated power.

This Function is enabled by default. To disable it, switch on Commissioning > Testing > DI active scheduling in the EcoFlow Pro app when the installer performs system commissioning. Or custom the DI values.

Custom Parameter

You can custom the following parameters in Commissioning > Device settings > Customize settings in the EcoFlow Pro app when the installer performs system commissioning.

• Connection parameters
• Voltage Protection parameters
• Frequency Protection parameters
• Reactive Power parameters
• Other parameters
