1 Overview
Introduction
This off-grid integrated solar power system consists of solar panel, lithium battery pack,
maximum power point tracking (MPPT) charge controller, and mounting bracket. The System
can be used in places without power supply and network connection. Specifically, it is
applicable to the following scenarios:
Supplying power for surveillance devices installed at places such as small construction
sites, mobile toilets, mobile waste stations, street vendor markets, temporary traffic
control zones.
Supplying power for surveillance devices installed at public places in parks, office areas,
residential buildings, and so on to prevent potential damages to infrastructures and
landscaping.
Features
All-in-one design, easy to install, remove, and maintain.
Aluminum alloy frame brings attractive appearance and excellent anti-corrosion
performance.
IP66 protection level.
RS-485 communications port and standard Modbus protocol, meeting communications
requirements in various scenarios.
MPPT controller helps significantly improve the energy utilization efficiency of the
System, and raise the charging efficiency by 10%–30% compared with conventional
PWM method.
Comprehensive electronic protection: Current limiting, short circuit, and reverse current
protection of solar panel; reverse connection, overcurrent, overdischarge, and
overtemperature protection of lithium battery; overload and short circuit protection for
device that consumes power.

4 Installation
Preparation
4.1.1 Installation Site Requirements
The installation site shall meet the requirements of electrical and relevant fire prevention
codes.
Choose an installation site with sufficient sunshine all the year round, and make sure no
shelter around the site to ensure natural lighting.
If there is shelter at the installation site, make sure the lowest installation position of the
System is at least 1 meter above the shelter, otherwise, it will lead to decline in power
generation and battery power loss, which will finally damage the battery.
Avoid public facilities such as underground cables, optical cables to ensure smooth
installation.
Make sure the back side of the System is well-ventilated.
4.1.2 Tools
Tools included in the packing list are provided. Besides, you need to prepare the tools shown
in Figure 4-1. Tools
