What is Solar Hybrid Inverter
Solar Hybrid Inverter is a power conversion equipment that integrates multiple functions and plays an important role in the solar power generation system,the following is a detailed introduction from the working principle, characteristics, application scenarios and other aspects.
1.Working principle
The solar hybrid inverter can simultaneously process direct current from solar panels, alternating current from the grid, and direct current from energy storage batteries,when solar energy is abundant, it converts the direct current generated by the solar panels into alternating current, with a portion used directly by the load, another portion stored in the batteries, or excess electrical energy fed back into the grid after meeting the load demand.
The inverter is equipped with an intelligent control system that can monitor parameters such as solar power generation, load power, battery capacity, and grid status in real time. Based on this information, it automatically adjusts the direction and distribution of energy to achieve optimal energy utilization,for instance, during the day when solar energy is abundant and load demand is low, it prioritizes storing excess electricity in the battery; at night or on cloudy days when solar energy is insufficient, it draws power from the battery to supply the load, and if the battery capacity is inadequate, it draws power from the grid.
2.Main features
High integration: The traditional solar inverter, battery charger, and intelligent energy management system are integrated together, reducing the number of devices and the footprint, thereby lowering the complexity and cost of the system.
Flexible working modes: Support for various working modes, including grid-connected mode, off-grid mode, and hybrid mode. In grid-connected mode, the system can connect to the power grid, enabling bidirectional flow of electricity; in off-grid mode, even during a power outage, the system can independently supply power to the load using solar panels and energy storage batteries; the hybrid mode combines the advantages of the first two modes and automatically switches based on actual conditions.
Improving energy utilization efficiency: Through intelligent energy management and scheduling, maximize the use of solar power generation, reduce dependence on the grid, and enhance energy self-sufficiency and utilization efficiency. At the same time, the presence of energy storage batteries allows for the storage of electrical energy during low electricity price periods and its release during peak electricity price periods, achieving arbitrage on the price difference between peak and off-peak electricity.
Enhancing power supply stability: During grid failures or power outages, solar hybrid inverters can quickly switch to off-grid mode, utilizing energy storage batteries to continue supplying power to critical loads, ensuring the continuous operation of important equipment and improving the reliability and stability of the power supply.
3.Application
Home photovoltaic power generation system: For household users, solar hybrid inverters can achieve self-sufficiency in household electricity, reducing electricity expenses. During the day when solar energy is abundant, excess electricity can be stored in batteries for use at night or on cloudy days, ensuring basic household electricity needs even during power outages.
Small commercial establishments: such as small factories, shops, hotels, etc., solar hybrid inverters can assist these locations in reducing their dependence on the grid and lowering operational costs. At the same time, in the event of a grid failure, they can ensure the normal operation of essential equipment, minimizing losses caused by power outages.
Remote areas and off-grid projects: In remote areas that are not covered by the power grid, solar hybrid inverters can combine solar panels and energy storage batteries to build an independent off-grid power supply system to provide a stable and reliable power supply for local residents and facilities.
Emergency backup power supply: In places with high requirements for power supply reliability, such as hospitals and data centers, solar hybrid inverters can serve as emergency backup power supplies, quickly providing power support during grid failures to ensure the uninterrupted operation of critical equipment.
