Hybrid Solar Inverter

Introduction
A common solar power system is composed of solar panel, solar charge controller, storage battery, inverter and other parts. The direct current generated by the solar panel is used to charge the storage battery with the help of the solar charge controller, and the stored direct current is converted into AC power supply by the inverter to power connected loads.

In order to improve power generation efficiency and reduce power transmission steps, our company combines solar charge controller and inverter together, forming this hybrid solar inverter.

Classification
Our product could be divided into two types, and their differences are listed below.

1. Mains Supply Type
The mains supply type takes mains supply as the master power supply, indicating that the loads will be powered by mains supply first if both mains supply and solar energy are available. When mains supply fails or some anomalies take place, this hybrid solar inverter will change direct current of the storage battery into stable alternating current to provide power for connected equipment, and this switch is completely automatic. When mains supply recovers, the mains supply will offer power again immediately.

2. Solar Energy Type
The solar energy type takes solar energy as the master power supply, and the electricity generated by solar panel has the priority to support loads when solar energy and mains supply are both available. Under the condition that the stored energy of the battery couldn't maintain normal working of the loads, the mains supply will take over and provide power.

Functions
1. Our product integrates DC-to-AC conversion, solar and mains supply charge/discharge control together. It adopts power frequency circuit design, and the output waveform is pure sine wave. Moreover, it can stand the inrush current when starting up inductive loads.
2. This hybrid solar inverter makes use of digital signal processor to achieve intelligent management. As a result, the system functions are powerful enough to deliver highly reliable performance.
3. This device itself only consumes little energy, and the conversion efficiency is very high, meaning that our product could make the best use of solar energy.
4. A number of protections are applied, such as overload protection, over temperature protection, output short circuit protection, DC over/under voltage protection, etc. After the storage battery recovers from overvoltage or under voltage problems, our product will be restarted automatically, perfectly meeting the requirements of unattended service.
5. The LCD display reveals all the operating parameters in a direct and clear way.

Applications
Our hybrid solar inverter fits for different kinds of loads in off-grid power generation system, such as televisions, computers, printers, fans, humidifiers, refrigerators, electric kettles, washing machines, air conditioners, microwave ovens as well as home-use electronic products.
