If you want to understand the functions of grid connected solar inverters and off grid solar inverters, you can read this article carefully, and Xindun Power will explain in detail from a professional perspective.
1) Off grid solar inverter
The photovoltaic power station with off grid solar inverter is also called an independent photovoltaic power station. It is a power generation system that operates independently without relying on the grid. It is mainly composed of solar panels, energy storage batteries, charge and discharge controllers, inverters and other components. The electricity generated by the solar panel directly flows into the battery and is stored. When it is necessary to supply power to electrical appliances, the DC current in the battery is converted into AC power by the off grid solar inverter.
The off grid solar inverter system can store the electricity obtained during the day for use at night. This process is realized through the controller and the battery. During the day, the controller stores the photovoltaic power in the battery, and at night the controller releases the power stored in the battery to be used by the power supply.
This is a repeated cycle of charging and discharging. This kind of off grid solar inverter power generation system is widely used because it is not restricted by region. It can be installed and used as long as there is sunlight. Therefore, it is very suitable for remote areas without grids, isolated islands, fishing boats, outdoor breeding bases, etc. It can be used as emergency power generation equipment in areas with frequent power outages.
2) Grid connected solar inverter
The grid connected solar inverter power station refers to the connected to the mains. The pv grid connected inverter power station has no electric energy storage device, and is directly converted into the voltage required by the national grid through the grid connected solar inverter, and is given priority to household use. Unfinished electricity can be sold to the state. However, power stations using pv grid connected inverter must first apply to the local national grid department.
Therefore, the grid connected solar inverter power system must rely on the existing grid to operate.
When the amount of solar power generated exceeds the amount of electricity used by household appliances, the excess electricity is sent to the public grid; and when the amount of solar power generated cannot meet the needs of household appliances, it is automatically supplemented from the grid. And the whole process is intelligently controlled and does not require manual operation.
However, the pv grid connected inverter system also has its disadvantages, that is, when the public grid fails, the photovoltaic power generation cannot operate.
3) However, Xindun Power has launched a hybrid inverter that can combine grid connected solar inverter and off grid solar inverter. Even when the hybrid inverter system is powered off, the power generation system can still operate normally.
The hybrid inverter can obtain the function of the off grid solar inverter and the function of the pv grid connected inverter, which is more practical!
Xindun Power mainly develops and designs off grid solar inverters and hybrid inverters. After 17 years of development and innovation, our inverter technology has obtained a number of patented technology certifications from authoritative organizations, with an area of about 10,000 square meters. On the premise of low manufacturing cost, high-speed production capacity and high-quality product are guaranteed.
