Photovoltaic energy storage principle
Photovoltaic energy storage system is a combination of photovoltaic power generation system and energy storage battery system, which mainly plays the role of “load regulation, storage of electricity, cooperation with new energy access, compensation of line losses, power compensation, improvement of power quality, isolation of power” in power grid work applications. Network operation, peak shaving and valley filling” and other functions. In layman’s terms, an energy storage power station can be compared to a water storage tank, which can store the surplus water during the trough period of electricity consumption, and use it when the electricity consumption peaks, thus reducing the waste of electric energy; in addition, energy storage The power station can also reduce line losses and increase the service life of lines and equipment.
Advantages of photovoltaic energy storage
Photovoltaic energy storage system improves the user’s self-consumption rate and brings greater benefits; at present, the self-consumption part of the user’s photovoltaic system is relatively low, perhaps less than 30%, and the combination of photovoltaic + energy storage will greatly provide Spontaneous self-use ratio, thereby increasing the profit of users. OSM battery is a high-voltage lithium battery, which adopts an expandable battery modular design (2-5) modules to flexibly combine. The appliance-style design is beautiful and elegant, and the intelligent design further simplifies installation and transportation. Using lithium iron phosphate batteries, it is safer and more reliable, with high efficiency and excellent performance, providing strong power for home power supply.
Photovoltaic energy storage is the development trend
Human development and sustainability must have energy, and it must be new and clean energy. For human beings to develop sustainably, they must have a clean environment. The energy storage battery OSM battery company currently provides 5KWH, 10KWH, wall-mounted and stacked styles of energy walls. There are two working modes of photovoltaic energy storage equipment: one is a grid-connected home energy storage system, and the other is an off-grid home energy storage system.
The grid-connected home energy storage system is divided into three working modes:
Mode 1: Photovoltaic provides energy storage and surplus electricity is connected to the grid;
Mode 2: Photovoltaic provides energy storage and some users consume electricity;
Mode 3: PV only provides partial energy storage.
Off-grid home energy storage systems are divided into three working modes:
Mode 1: Photovoltaic provides energy storage and user electricity (sunny day);
Mode 2: Photovoltaic and energy storage batteries provide users with electricity (cloudy day);
Mode 3: The energy storage battery provides users with electricity (evening and rainy days).
Photovoltaic energy storage applications
With the sharp reduction in the price of energy storage batteries and the diversification of energy storage system equipment, according to the electricity consumption, the energy storage system can be used skillfully to improve economic benefits. Parallel energy storage systems can also be installed in places where photovoltaics have been installed. The grid-connected energy storage photovoltaic power generation system can store excess power generation and increase the proportion of self-generated self-consumption. It is suitable for applications such as photovoltaic self-generated and self-consumption that cannot be connected to the Internet, self-use electricity prices are more expensive than on-grid electricity prices, and photovoltaic power generation and electricity consumption are not at the same time period. OSM battery has obtained the EU CE certification, and the safety of the battery is guaranteed. Currently, their products are sold worldwide.
