Photovoltaic energy storage smart system

The smart solar energy storage system has become a "timely rain" to save the energy crisis. In terms of low-carbon technologies that are key to development, solar power, wind power generation and large-scale renewable energy storage and grid-connected technologies are also included. The implementation of the energy storage policy has greatly promoted the rapid development of the solar storage and charging market.

Optical energy storage smart system consists of photovoltaic power generation, energy storage, electric vehicle charging, energy management and other units. The system can realize the "trinity" of power generation, charging/discharging, and energy storage. The photovoltaic power generation unit meets the load power consumption and charging needs, and the excess power is merged into the public grid, which can realize the dual benefits of photovoltaic power generation and charging operation. The energy storage unit takes advantage of the difference in peak-valley electricity prices, absorbs low-priced "valley electricity and flat electricity", releases electricity during peak electricity consumption, earns the difference between peak-valley electricity prices and peak-to-valley electricity prices, and can reduce enterprise electricity consumption through peak shaving management and control. peak, thereby reducing the basic electricity bill of enterprises. The optical storage and charging integrated system supports various communication interfaces such as Ethernet, 3G, 4G, RS485, etc., and can log in to the “Sun Chasing Cloud” management platform through the mobile phone APP or computer to realize intelligent operation and maintenance, centralized management, and remote monitoring.

Application scenarios

Industrial and mining enterprises, business centers, etc. with insufficient power supply or unstable power grid;

Government agencies, scientific research parks and confidential departments that require uninterrupted power supply;

Traffic-intensive stations, terminals and airports, outdoor temporary large load centers;

Nuclear power, wind power and other power generation facilities that need nighttime energy storage for daytime use;

Power stations that require a "black start" function;

Multi-energy complementary energy such as solar energy and wind energy with fluctuating power generation quality;

Areas where the development of small thermal peaking power stations or other high-polluting power stations is restricted due to environmental concerns;

Islands and remote mountains far away from the mainland.

The smart solar energy storage system can be a power generation/distribution system that integrates a variety of distributed energy sources (such as photovoltaics, wind power, diesel power generation, small hydropower, etc.), energy storage devices, electricity loads, monitoring systems and protection devices. An autonomous system that achieves self-management, control, and protection according to predetermined goals.
