An energy storage inverter represents the latest generation of inverters available on the market. Its primary function is to convert alternating current (AC) into direct current (DC) and store it in batteries. During a power outage, the inverter converts the DC stored in the batteries back into AC for user consumption. This device allows for bidirectional conversion between grid power and battery power, overcoming the limitation of photovoltaic (PV) inverters that can only be used during the day. This capability is a significant reason for its growing popularity among users.
Functions and Advantages of Energy Storage Inverters:
-
Overcoming Weather Constraints The ability to convert AC to DC and store it means that energy storage inverters can provide power during outages, significantly reducing the impact of weather conditions on power generation stability and enhancing the overall stability and quality of the grid.
-
Higher Energy Efficiency Compared to grid-tied PV inverters, energy storage inverters offer higher energy efficiency. They not only overcome limitations related to weather and time but also address issues associated with grid-tied PV inverters. They provide users with more stable and long-lasting power, avoiding inconveniences caused by power system failures.
-
High Stability In the event of a grid system failure, energy storage inverters can convert stored DC directly into AC for the grid, minimizing external influences and reducing electricity costs. They offer high stability. During peak electricity usage, the inverter converts solar DC into AC and feeds it into the grid; during off-peak times, it converts grid AC into DC for storage, allowing for bidirectional conversion and robust power support during outages.
Additionally, energy storage inverters provide more stable, cleaner current with fewer harmonics, aligning with current energy-saving and emission-reduction trends and further enhancing grid stability and quality.
In summary, energy storage inverters overcome the limitations of traditional PV inverters by providing high-quality power to the grid system, reducing electricity costs, and improving energy efficiency. These advantages ensure that energy storage inverters hold a competitive edge in the market.
