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.
Figure 1 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.

5. Installation
5.1. Selecting Mounting Location
Consider the following points to install the energy storage Pack:
 Do not mount the Pack on flammable construction materials.Mount on a solid surface;

Install this Pack module at eye level in order to allow the readability of LCD display at all times.
 For proper air circulation to dissipate heat, please leave a gap of about ＞0.3 meter from the ground,30 cm
from the side of the device.

The ambient temperature should be between 0°C and 40°C and relative humidity should be between 25%
and 85% to ensure optimal operation.

The recommended installation is flat wise adherence.
Install the battery module in a dry, protected area with no excessive dust and sufficient air circulation. Do not
operate in locations where the temperature and humidity are outside the specified range.
5.2. Mounting The PACK
When installing the Pack bracket, use appropriate screws to fix it. After that, the equipment should be
firmly bolted.The pack can be run indoors or outdoors. However, only professional personnel can enter
this area for installation or maintenance.
