3 Product Introduction
3.1 Brief Introduction to Product All-In-One Energy Storage System is a new generation of household energy storage system with two output
specifications of 220V and 110V, which can meet the diversified needs of global users. The All-In-One Energy
Storage System energy storage system adopts a modular design, including power modules and battery
expansion modules, so it can be easily combined into a system of any capacity required by the user.
The lithium iron phosphate batteries with high performance and long service life are used in the energy
storage module. Meanwhile, the modular structure design is adopted. Each energy storage module is internally
integrated with the intelligent BMS system, which can be easily expanded and can be combined into 20Kwh
battery pack at most.
The brand new topological circuit design is adopted in the power module, which can realize the energy
exchange between photovoltaic, mains, battery and loads, and has the function of photovoltaic and mains
charging. The photovoltaic charging module adopts the latest optimized MPPT tracking technology, which can
quickly track the maximum power point of the photovoltaic array in any environment, and obtain the maximum
energy of the solar panel in real time. In addition, MPPT has a wide voltage range. The advanced control
algorithm is adopted in the mains charging module to realize the fully-digital double closed-loop control of
voltage and current, so the control precision is high and the volume is small. The AC voltage input range is wide,
and the input/output protection functions are complete, which can realize the stable and reliable charging and
protection of batteries. The inverter module is based on the full-digital intelligent design, adopts the advanced
SPWM technology, outputs pure sine wave, converts direct current into alternating current, and is applicable for
household appliances, power tools and other AC loads.
The typical topological diagram for application of the system is as follows:

2.Operating steps：
A.Connect the computer and battery using a USB to 232 wire harness, plug the USB port into the USB port
of the computer, and connect the other end of the wiring harness to the battery RS232 interface.
B.Download the software compression package to the computer as follows:
C.Unzip the compressed package to the current folder as follows:
D.Open the extracted folder and select the application in the folder as follows:
E.Double click on the above icon to enter the monitoring interface as follows:
15

F.After entering the monitoring interface, click on the “Open” and then click on “Try Connect”. When battery
communication succeeded, the real-time information will be displayed on the left side of monitoring interface,
and the “Password”will display green.
G.After communication is normal, enter the password 123456 in the password status bar in the bottom right
corner. After entering it correctly, the status bar will display green.
H.Click "System Config" as follows
I.Click "Read" on the middle (inverter protocol) section on the right side of the display interface to check
