1. Introduction
The Energy storage pack is an essential component of the photovoltaic power generation system. It can
provide electricity for the connected load, and it can also store photovoltaic solar modules, fuel generators, or
wind energy generators by charging the remaining energy in case of emergency. When the sun goes down,
energy demand is high, or there is a power outage, you can use the energy stored in the system to meet your
energy needs at no additional cost. In addition, the energy storage Pack can help you achieve energy self-
consumption and ultimately achieve the goal of energy independence. According to different power
conditions, the energy storage PACK can output power during peak power consumption, and can also store
energy during low power consumption. Therefore, when connecting the matching photovoltaic modules or
inverter arrays, external equipment is required to match the energy storage the working parameters of the
pack to achieve the highest operating efficiency. For a simple diagram of a typical energy storage system.
Energy storage System Overview
It is very important and necessary to read the user manual carefully before installing or using the battery. Failure to
follow any of the instructions or warnings in this document can result in electrical shock, serious injury, death, or
may damage the battery and the whole system. If the battery is stored for a long time, it is requirement that they are
charged every three to six months, and the SOC should be no less than 80%,after fully discharging,The battery needs
to be recharged within 12 hours.
Do not expose cable outside;
Do not use cleaning solvents to clean the battery.
All battery terminals must be disconnected before maintenance.
2. Important Safety Warning
Do not expose the battery to flammable or harsh chemicals or vapors.
Do not paint any part of the battery, include any internal or external components.
Do not connect battery with PV solar wiring directly.
Any foreign object is prohibited to be inserted into any part of the battery.
Our company will not bear any warranty claims for direct or indirect damage caused by violation of the above
items.

2.1 Before Connecting
After unpacking, please check the battery and pack list first, if the battery is damaged or spare parts are missing,
Please contact the dealer. Before installation, be sure to cut off the grid power and make sure the battery is in
the turned-off mode; Wiring must be correct, do not mix-connect the positive and negative cables, and ensure
no short circuit with the external device; It is prohibited to connect the battery with AC power directly;
The BMS in the battery is designed for 48VDC, DO NOT connect battery in series; It is prohibited to connect
the battery with different type of battery; Please ensure the electrical parameters of battery system are
compatible to inverter; Keep the battery away from fire or water.
3. Necessary installation Tools.
Tool preparation: wall-mounted electric drill, hammer, Phillips screwdriver, M8/10 wrench, multimeter, etc.
Personal protective equipment
Optional(computer

5.4 Floor Standing Installation(10kwh)
1. Floor-standing type: Support the lithium battery pack equipment on the ground through the lower 4 feet;
install the battery shell and wall handle to prevent it from falling forward; install the handle (both sides): first
tighten the M4*6 flat head screws as shown in the figure Display direction is fixed:
2. Use expansion screws to fix it to the wall:
6. Wiring operation guide:
6.1 Power Cable connection:
Use a cross screwdriver to remove the protective cover of the battery wiring compartment. The 5KWh
protective cover is located on the lower right side of the housing (marked by the red line), and the 10KWh
protective cover is located on the upper right side of the case. Then pass the wire harness through the
protective coil at the bottom of the battery and lock it. on the corresponding terminal. See below

10 / 15
The red wire (positive pole) for ++ terminal (++ terminals are all positive, just connect any one);
