SE priority mode of Solar Energy Storage System
In the context of the increasing importance of renewable energy, Solar Energy Storage Systems, as a high-efficiency power management solution that combines solar power generation with energy storage systems, have gradually become an ideal choice for home and commercial users. The SE (Solar Energy) priority mode of optical storage is an intelligent power management mode that can optimize energy supply according to user needs and effectively reduce power costs. This paper will introduce the SE priority mode and its working principle of Solar Energy Storage System in detail.
the working principle
In SE priority mode, the user can set a specific "SE time" period. During this time period, the power supply and charging mechanism of the system will be carried out according to the following process:
Power configuration within SE time
Mains bypass: The system preferentially uses mains to supply power to loads within the SE time set by the user. In this case, the user's load is supplied through the mains connection to ensure the stability of the power supply.
Battery charging mode: At the same time, the mains will be used to charge the battery. The system also uses solar power to charge the batteries. Through this configuration, the user not only obtains a stable source of electricity, but also effectively improves the battery power to ensure the reliability of its subsequent use.
Power supply mode outside SE hours
Outside the set SE time, the system is mainly powered by solar energy. When the solar power generation is insufficient to meet the user's load demand, the battery will automatically supplement the required power to ensure that the user's electricity consumption is not affected. When the remaining battery capacity (SOC) drops to 10% or less, the system automatically switches to mains power. This design can effectively avoid excessive discharge of the battery and extend the service life of the battery.
Charging and power switching
Once switched to mains power, the system automatically starts charging the battery while continuing to supply power to the load. When the battery is full, the system will automatically switch back to solar and battery power supply for efficient use of photovoltaic power generation and energy storage resources.
Emergency power supply mechanism
If the battery is seriously low and the mains power is off, the system automatically cuts off the load power supply. The photovoltaic system will then charge the battery until the SOC is 40 percent charged. When the battery level is restored to this level, the system will restart the load power supply, ensuring that the user's electricity needs are met in any case.
Flexibility in energy management
The SE priority mode also supports the flexible use of time-sharing metering price. Users can set the power function according to the load of the power grid and the price of electricity. When the grid load is low and the price is cheaper, the system can use the mains power to charge the battery, and in the peak period of the price, the power stored in the battery is used to supply power, so as to achieve the purpose of off-peak power consumption and energy saving and cost reduction.
advantages
Optimize economic benefits: Users can use the electricity price difference reasonably through the wrong time power consumption function to achieve effective savings in electricity costs and enhance economic benefits.
Ensure the stability of power supply: in the set SE time, through the mains power supply, to ensure that the user's power demand is not affected, especially suitable for home or business environment in the peak electricity hours.
Enhance battery life: Through the intelligent charging strategy, the phenomenon of overdischarge and overcharge of the battery is reduced, and the service life of the battery is effectively extended.
Flexible energy scheduling: This model provides the ability to manage power flexibly and intelligently adjust power usage according to load demand and external prices to maximize energy efficiency.
Strong emergency capacity: in the case of mains power failure, the system can actively switch to ensure battery charging and ensure that the user's power supply is not interrupted under any circumstances.
CONCLUSION
The SE priority mode of the Solar Energy Storage System combines solar power generation, energy storage and mains use organically through the intelligent energy management mechanism, which greatly improves the flexibility and economy of the user's electricity consumption. This model can not only ensure the stability of power supply, but also adjust efficiently according to specific electricity demand and price strategy. With the continuous advancement of technology and the popularization of renewable energy, optical storage devices will play a greater role in helping to achieve a green and sustainable energy future.
