A low-voltage single-phase hybrid inverter is an electrical device that can convert DC and AC power in both directions. It's frequently utilized in renewable energy systems like solar and wind power, as well as in residential, commercial, and industrial settings. This study will explain the fundamental concept, operating principle, benefits, and application scenarios of low-voltage single-phase hybrid inverters.
The following three aspects can help you understand the fundamental principle of a low-voltage single-phase hybrid inverter:
Low-voltage: The input voltage of low-voltage single-phase hybrid inverters is typically between 12V to 48V, which can reduce electrical equipment costs and safety risks.
Single-phase: The output voltage of a single-phase hybrid inverter is a single-phase alternating current (AC), usually 220V or 110V, which is suitable for most household and commercial appliances.
Hybrid: Hybrid inverters can not only convert DC to AC but also convert AC to DC for bi-directional power flow. In this way, hybrid inverters can be combined with renewable energy sources such as solar and wind to achieve optimal energy use.
The working principle of a low-voltage single-phase hybrid inverter can be divided into the following two modes:
Inverter mode: when the input power is DC, the low-voltage single-phase hybrid inverter converts the DC power to single-phase AC power through switching tubes and transformers and outputs it to the load or the power grid.
Inverter Mode: When the input power is AC, the low-voltage single-phase hybrid inverter converts the AC power into DC power through a rectifier bridge and filter capacitor and outputs it to the battery or DC load. Click here for our portable power station.
The low-voltage single-phase hybrid inverter can automatically switch between inverter mode and converter mode according to the type of input power and the demand of the load, to realize the bidirectional conversion and balancing of electric energy.
A low-voltage single-phase hybrid inverter has the following advantages over a traditional one-way inverter:
Low-voltage single-phase hybrid inverters can receive inputs from a variety of DC power sources, such as solar panels, batteries, generators, etc., as well as inputs from a variety of AC power sources, such as the power grid and diesel generators. In this way, the low-voltage single-phase hybrid inverter can automatically switch its working mode according to different energy conditions to ensure a stable supply of electricity.
The conversion efficiency of low-voltage single-phase hybrid inverters is generally above 90%, which can save a large amount of energy compared with traditional one-way inverters. At the same time, the low-voltage single-phase hybrid inverter can also realize intelligent control, automatically adjusting the output voltage and frequency according to the demand of the load, further improving energy efficiency.
The cost of low-voltage single-phase hybrid inverters is much lower compared to high-voltage three-phase hybrid inverters. This is because the circuit design of low-voltage single-phase hybrid inverters is simpler, requires fewer components, and can use cheaper materials. In addition, low-voltage, single-phase hybrid inverters are easier to install and maintain, which saves labor and material resources.
Renewable energy system: Low-voltage single-phase hybrid inverters can be combined with renewable energy systems, such as solar and wind energy, to achieve optimal use of energy. For example, when the power generated by solar panels exceeds the demand of the load, the low-voltage single-phase hybrid inverter can store the excess power in the battery or feed it back into the grid to gain revenue. When the power generated by the solar panels is not enough to meet the demand of the load, the low-voltage single-phase hybrid inverter can supplement the power from the battery or the grid to ensure the normal operation of the load.
Low-voltage single-phase hybrid inverters can be used as the core component of off-grid power systems to provide reliable power to areas far from the grid. For example, the low-voltage single-phase hybrid inverter can provide living power for residents in rural areas, mountainous areas, islands, and other areas, as well as portable outdoor energy storage power supply for activities such as fieldwork, camping, and traveling.
Low-voltage single-phase hybrid inverters can be used as an important part of the emergency backup power system to provide timely solutions for sudden power interruptions. For example, low-voltage single-phase hybrid inverters can provide emergency power for important places such as hospitals, schools, and shopping malls, as well as temporary power for ordinary places such as homes, offices, and factories.
