3. Powerporter Function
About Power Porter
This product is mainly combined with inverter, photovoltaic (PV) and related accessories
to build residential energy storage system. The system is used to store the direct current
(DC) generated by photovoltaic (PV) in the connected battery, and convert the direct
current (DC) generated by the connected battery into alternating current (AC) and provide
it to the home grid.

8
(Note: The actual Residential ESS may also include electrical equipment such as
distribution boxes and metering meters)
Powerporter is a lithium-ion battery pack that can store electrical energy and outputs DC
current. Powerporter only maintains electrical connection with the inverter. The electrical
energy generated by the PV is converted by the inverter Dc to DC and stored in the
connected Powerporter. When Powerporter is needed, Powerporter’s electrical energy is
converted by the inverter DC to AC and transmitted to the home grid to provide power for
household appliances.
The main function of the home energy storage system depends on the inverter.
Powerporter is a device that stores electrical energy.
Functions of home ESS:
Self-production and sales of electrical energy
Use solar power and Power Porter to reduce the dependence on the grid and store
electricity during the day for night use.
Backup power
When the power grid is out of power, it can be seamlessly switched to Power Porter as
a backup power source to protect your home from power outages.
Sell electrical energy
The electrical energy generated by the photovoltaic array can be stored in a connected
Powerporter or sold to an energy supply company.

9
Pure off-grid power supply
The system can be connected to diesel generators to ensure uninterrupted power
supply in areas without city power (such as islands and remote mountain areas).
(Note: The scheduling management of electrical energy in the system depends on the
inverter. Powerporter is committed to being compatible with a variety of inverters. The
inverter you use does not necessarily contain all the above functions)
Monitoring Your System
Using the app, you can monitor system operation from your mobile device, including the
following:
Real-time power usage
Energy consumption history
Relative amounts of energy used from solar, grid, and Powerporter storage

Powerporter power cable connection
The positive and negative poles of the Powerporter adopt a quick-plug interface, and the
positive and negative poles can be distinguished by color (orange indicates the positive
pole, black indicates the negative pole), and the installer can directly connect the power
harness to the positive and negative poles of the product when wearing protective gloves.
The power harness is connected with the Powerporter through a quick-plug interface, and
connected with the inverter through a ring terminal.
Insert the ring terminal of the power harness into the battery connection port of the inverter,
and ensure that the bolts are tightened with a torque of 2 ~ 3Nm. Make sure the polarity of
the battery charge is properly connected, and the ring terminal is tightened with the inverter
end.
Power wiring harness connection steps:
① Confirm that the inverter mains line is open and the PV line is open. Confirm that
Powerporter is shut down.
② The ring terminal of the wiring harness is connected to the positive and negative poles
of the DC terminal of the inverter.
③ The negative quick connector is connected to the negative port of Powerporter.
④ The positive quick connector is connected to the positive port of the Powerporter.
Warning: Before the installation of the power harness, the Powerporter and the

13
inverter must be turned off.
Power harness disconnection steps:
① The inverter mains line is open, and the PV line is open. Turn off the inverter switch.
② Wait until the inverter screen is closed.
③ Press and hold the POWER button until the button light turns off.
④ Remove the quick plug connector of the negative power harness.
⑤ Remove the quick plug connector of the positive power harness.
