System Operation
SYSTEM POWER ON
1. Turn the BATTERY SWITCH on the converter to the ON position.
2. Press and hold the BATTERY ON/OFF button on the converter for about
5 seconds. Wait until the LEDs light up and then flash twice, indicating a
successful system power-on.
SYSTEM POWER OFF
1. Shut down the system via the EcoFlow app.
2. Turn the BATTERY SWITCH on the converter to the OFF-BYPASS position.
3. Press and hold the BATTERY ON/OFF button on the converter for about 10
seconds.
4. Wait until the LEDs are completely off, indicating a successful system power-
off.
SYSTEM MODES
Operating Mode
When the BATTERY SWITCH is set to ON, the system works in operating
mode.
In operating mode, the system stores the excess electricity generated by solar
panels, and then supplies it to the home load when solar power is insufficient.
PV power first supports local loads via a solar inverter, then charges the
storage system with excess solar energy.
The system discharges when PV power is low.

PV-STORAGE SYSTEM CO-WORKING TIPS
Work with Third-Party I-V Curve Scan
If your solar inverter supports an I-V curve scan or diagnosis feature, turn off
the storage system first to obtain accurate scanning reports of photovoltaic
details.
Turning off the storage system:
1. Shut down the EcoFlow PowerOcean DC Fit via the EcoFlow app.
2. Run the I-V curve scan via your inverter's management interface. Await for
the I-V curve scan report.
3. Start up the EcoFlow PowerOcean DC Fit via the EcoFlow app.
Keep the Solar Inverter On at Night
Some solar inverters may shut down at night to save energy. To ensure the
storage system continues to supply power to home appliances, keep the
inverter running at night.
System Management
EcoFlow provides thorough support for the system. Both the end user and
installer benefit from our comprehensive guides and resources.

Bypass Mode
When the BATTERY SWITCH is set to OFF-BYPASS, the system works in
bypass mode.
In bypass mode, the system does not function as a power storage or backup
unit. The electricity produced by solar panels goes to the PV inverter through
the converter.
