System Introduction
With the development of modern technology and the reduction of costs, solar energy becomes increasingly affordable, and it has become one of the most important alternatives to fossil energy. The residential photovoltaic intelligent charging & storage system generates power in the same way as a common grid-tie solar system but uses special hybrid inverters and batteries to store energy for later use, such as AC chargers or other household loads.
With electricity demand rising over the past decade, many people are now realizing the benefits of going solar: clean, renewable energy, at a fraction of the price that utility companies charge to use power from the grid. For areas with unstable electricity and high electricity prices, it provides more opportunities for the development of residential energy storage systems. It can not only improve energy efficiency, but also reduce the impact on the grid and increase residents' income.
System working principle
Photovoltaic power generation is a technology that utilizes the photovoltaic effect at semiconductor interfaces to directly convert light energy into electrical energy. The key component of this technology is solar cells. After being connected in series and packaged for protection, solar cells can form large-area solar cell modules, which are combined with power controllers and other components to form photovoltaic power generation devices. The advantage of photovoltaic power generation is that it is less restricted by geographical conditions, as sunlight shines on the earth; Photovoltaic systems also have the advantages of safety and reliability, no noise, low pollution, no need to consume fuel, on-site power generation and supply without the installation of transmission lines, and short construction period.
The photovoltaic array converts solar energy into electrical energy under illumination, supplies power to the load through a solar charging and discharging controller, and charges the battery pack at the same time; When there is no light, the solar charging and discharging controller supplies power to the DC load from the battery pack, while the battery also directly supplies power to the independent inverter. The independent inverter converts the current to power the AC load.
