Why SOC Energy Storage Is the Talk of the Town Ever wondered how your phone knows exactly when to scream "Low battery!" at 3 AM? Meet SOC energy storage - the
SOC (State of Charge) is the percentage that represents the charge level of a battery in a solar power system. It indicates how much energy is stored in the battery compared to its full capacity. For example, if a battery’s SOC is at 80%, it means that the battery is 80% charged and 20% of its capacity is still available for charging.
In solar energy systems, understanding the State of Charge (SOC) is crucial for efficient energy management. SOC refers to the percentage of a battery's total capacity that has been charged, providing key insights into its current state and how much energy is available for use.
In a solar energy storage system, proper SOC monitoring ensures that the battery operates within an optimal range, balancing the needs of the user with the health of the battery. Without accurate SOC management, the system could either overcharge or undercharge, reducing its efficiency and lifespan.
In this blog, we will explore these critical aspects of energy storage, shedding light on their significance and how they impact the performance and longevity of batteries and other storage systems. State of Charge (SOC) is a fundamental parameter that measures the energy level of a battery or an energy storage system.
I'm not clear. There is a Max SoC setting but it only applies to charging from the grid, if there is enough solar PV available the battery will charge to 100% from it. There's two MinSoC settings, as you might want a different threshold if you're using the system offgrid as opposed to grid connected.
Compared with the traditional control strategy, the proposed control strategy can effectively balance the SOH and SOC of each energy storage unit and keeps the system's overall capacity for a longer period.
