On Grid Solar System With Battery Backup - HT SOLAR POWER
On Grid Solar System is that the DC power generated by solar modules is converted into AC power that meets the requirements of the mains power grid through a grid-connected inverter, and then directly connected to the public power grid.
System introduction:
The biggest feature of On Grid Solar System is that the DC power generated by the photovoltaic array is converted into AC power that meets the requirements of the mains power grid through the grid-connected inverter and then directly connected to the mains power network. In addition to supplying the AC load, the power generated by the PV array also Power is fed back to the grid. On rainy days or nights, when the photovoltaic array does not generate electrical energy or the generated electrical energy cannot meet the load demand, the grid supplies power to the load.
Working principle
The photovoltaic grid-connected system is a system that connects the solar photovoltaic system to the power grid. The grid-connected inverter is the core component and key technology of the grid-connected photovoltaic power generation system.
In addition to converting the DC power emitted by the photovoltaic array into AC power, unlike ordinary inverters, the grid-connected inverter also needs to analyze the frequency, voltage, current, phase, active and reactive power, and power quality (voltage fluctuations) of the converted AC power. , high-order harmonics), etc. are controlled to make the voltage and frequency of the converted alternating current consistent with the voltage and frequency of the grid alternating current.

System advantages
Because electric energy is directly input into the grid, there is no need to configure a battery, and the process of battery energy storage and release is eliminated. The power generated by the PV array can be fully utilized, thereby reducing energy loss and reducing the overall cost of the system. The main advantages are as follows:
Scope of application
Industrial factories, commercial buildings, agricultural facilities, municipal offices and other public buildings, as well as households, villas and other private residences and parks, etc.
