Off-Grid solar inverter – type3 (3.5kW, 5.5kW)-details2

A solar system is a system that converts the DC electricity absorbed by the sun and converts it into usable AC electricity for use by people. The inverter is responsible for converting the direct current into alternating current and regulating it to match the voltage of the appliances used. The inverter therefore plays a very important role in the system.

The off-grid inverter can work independently of the grid and is equivalent to a mini-grid on its own. It can control its own voltage and can therefore be regarded as a voltage source. It can basically drive any load that is within the power range of the inverter. It can be very useful in areas off the grid and in areas where the power supply is unstable, such as deserts and desert plateaus, where deep forested areas can be used to provide power needs whenever and wherever they are needed.

Cost of off grid inverter

The biggest disadvantage of off grid inverter is that the cost is much higher than that of grid connected inverter. Because the off-grid inverter needs to cooperate with the battery to be more stable, and generally, the off-grid inverter needs to be used together with the battery. Therefore, it is not only that the price of off grid inverter is higher than that of grid connected inverter, but also that the battery in the whole set of corresponding supporting equipment is essential. This will lead to higher costs. But everything has two sides. The convenience that the energy storage system can bring cannot be ignored. Many users choose it because of the actual demand for energy storage. In addition, the cost of off grid inverter and battery is continuously reducing, which makes the off-grid inverter have its own market, and the market is becoming larger and larger.
