Discussion on knowledge points of off grid power generation systems

The off grid power generation system, as the name suggests, is a system that operates independently without relying on the national power grid. In fact, it is also called an off grid solar power generation system, which is composed of solar panels, controllers, batteries, and inverters. Below are some relevant knowledge points for everyone.

When using off grid power generation systems, everyone should know that comparing solar panels to the core of off grid power supply systems is not an exaggeration. The main function is to use the photovoltaic effect to convert light into electrical energy, and then store the electrical energy. In the battery, then release electrical energy when needed for power generation. When inverters are used to exchange loads, the controller has automatic control functions such as overcharging, over discharging, electronic short circuit, overload protection, and anti reverse connection. Therefore, the off grid power generation system has a wide range of applications and is relatively easy to install and use. It can solve the problem of insufficient power supply in areas without power grids or with frequent power outages. In fact, it is mainly used in remote areas where there is no power grid coverage, to solve the problem of household electricity consumption for residents, as well as emergency power supply. In addition, off grid power generation systems can also be used in transportation, automotive components, communication, aerospace, and other fields.

The difference between off grid power generation systems and grid connected power generation systems is that the former does not rely on the national grid, while the latter requires grid connection; Off grid power generation requires batteries, so there are batteries available, while grid connected power generation does not require batteries to provide it. And there is no need to use batteries during use, greatly saving costs. Especially the new grid connection policy introduced by the country clearly stipulates that household photovoltaic power stations can be connected to the grid for free, and excess electricity can also be sold to power companies. Therefore, in the long run of investment, based on the 25 year service life of household photovoltaic power stations, the cost can be recovered in about 6-10 years, and the remaining 10 years will be profitable. Therefore, in order to save electricity costs and provide convenient power supply, grid connected solar power generation systems should be chosen, which is currently the mainstream method. Of course, due to the direct input of electricity into the public grid, the off grid power generation system does not require the configuration of batteries, eliminating the storage and release process of batteries, reducing energy loss, saving space and system investment, maintenance, and also effectively reducing costs; It can be done greatly to ensure the reliability of electrical equipment power supply.
