1. Product Description

1.1 Overview

Off grid solar panel system can realize self power supply of electric equipment and is suitable for those places without public grid or where have electricity shortage often.

The solar power generation system has obvious pertinence, which can be customized according to the specific use requirements of users to achieve the best cost performance. The following factors need to be considered in the design:

The daily electricity consumption determines the total power of the solar panels.
The model of the solar recharge controller is determined by the number of solar panels and batteries.
The capacity of the battery determines the total amount of power that can be stored.
The total power and category of the household appliance determines the model of the inverter.
Sun insolation in different places.
User habits and requirements.

1.3 Working Principle

 In the off grid solar power system, solar panels convert sunlight into dc electricity,which is through solar recharge controller and stored in the battery. Then electricity is through off grid inverter, At this moment, the low-voltage DC electricity is converted into high-voltage AC electricity for electric equipment.
