AC priority mode of Solar Energy Storage System
With the promotion of renewable Energy and the continuous progress of technology, Solar energy Storage System as an efficient energy management system is more and more favored by users. In the optical storage unit, AC (mains) priority mode is an important working mode, which can ensure the user's electricity demand at the same time, intelligent management of battery and solar energy use. This paper will introduce the AC priority mode and its working principle of optical storage unit in detail.
the working principle
Mains priority
In normal cases, the system preferentially uses AC (mains) to supply power to users. If the battery is fully charged, the mains is only used to meet the load demand and is not used for battery charging. This mode ensures that users can obtain a stable power supply at the lowest cost, and reduce the frequency of battery use, and extend the service life of the battery.
Battery charging function
When the battery power is seriously insufficient, the system will charge the battery through the mains while meeting the user's load. At this time, the solar system will also synchronously charge the battery, ensuring that the battery is restored to a sufficient state of power in a short time.
Switching when mains power is lost
When mains power is lost, the system automatically detects this change and switches to solar power mode. If the electricity generated by solar energy can meet the user's load needs, the photovoltaic system gives priority to using solar energy for power supply. At the same time, the excess electrical energy will be used to charge the battery pack to keep it in good condition.
Battery supply supplement
If the power generated by the solar energy cannot meet the load demand, the system will automatically supplement power from the battery to ensure that the user's electricity consumption is not affected. The use of batteries ensures continuity of electricity consumption, especially on cloudy days or in the case of insufficient light at night.
Battery power monitoring and control
When the mains power is off and the battery power is seriously insufficient, the system will actively cut off the load power supply and use solar energy to charge the battery until the SOC (state power) of the battery is charged to 40%. After reaching this charging state, the system will restart the load power supply to ensure the basic electricity demand of the user.
Automatic switching after the mains is restored
If the battery is connected to the mains during the battery charging process, the system automatically switches back to the AC (mains) power supply mode, and starts the mains to charge the battery and the solar to charge the battery. This not only keeps the battery fully charged, but also ensures that the user's electricity needs are met in all circumstances.
advantages
Stable power supply guarantee: In AC priority mode, the use of mains power as the main power supply can stably protect the power consumption of users and avoid power outages caused by insufficient batteries or solar power generation.
Extended battery life: Because the mains power is used first when the battery is fully charged, the frequent charging and discharging of the battery is reduced, which helps to extend the life of the battery and reduce maintenance costs.
Flexible energy management: This model provides a flexible energy management solution with efficient power dispatch capabilities that can quickly respond to different power supply needs and environmental conditions.
Emergency power supply capacity: in the case of mains power failure, the system can quickly switch to solar and battery power supply, anxious users in extreme weather and other unexpected situations of electricity safety.
Economic benefits: By prioritizing the use of mains power, users can optimize the cost of electricity use, inject more solar energy into the battery, and improve economic benefits.
CONCLUSION
The AC priority mode of the optical storage unit ensures the safety and stability of users in daily electricity consumption through intelligent management of batteries and solar energy. This model can not only guarantee the power supply effectively, but also provide users with flexible energy choices and economic benefits. With the continuous evolution of the energy structure, the AC priority model will play an important role in the application of optical storage units, promoting the greater popularization and application of renewable energy in homes and businesses. With further technological development and policy support, future energy management will be more efficient, environmentally friendly and intelligent.
