What is a Hybrid-Inverter?
A hybrid-inverter regulates the flow of energy among your solar panel power, battery storage, and the grid. It also converts DC electricity from your batteries into AC power for use with appliances and devices that plug into regular outlets.
Look for a hybrid inverter that can operate in grid-tied mode and backup mode, allowing excess energy to be sold back to the power company or used to back up household essential circuits. Some have additional functionality such as power optimisers to condition electricity for conversion.
Battery Integration
A hybrid inverter interfaces with solar panels and battery storage systems to transform the direct current (DC) energy produced by your solar array into alternating current (AC) power. It can then store excess power into batteries and use it during periods of high usage or low solar production, helping to minimize electricity bills.
The inverter’s advanced features help maximize energy utilization and efficiency. lifepo4-battery-storage-system For example, maximum power point tracking (MPPT) technology optimizes the performance of your solar panel system under different conditions and improves energy production. In addition, the inverter’s integrated energy management modes allow you to prioritize the use of solar power over grid power or utilize a “peak shaving” mode that strategically uses battery capacity in line with peak and valley electricity rates.
The inverter also allows you to export excess solar energy back to the grid, generating credits and potential monetary benefits for homeowners. And a multi-mode hybrid inverter can provide backup power, known as an emergency power supply (EPS), to support lighting and basic power circuits or smaller air-conditioning units up to 3kW for a period of time when the grid is out of service.
Grid Integration
A hybrid inverter allows your solar energy system to seamlessly integrate with the electricity grid and optimizes the flow between your panels, battery storage and the grid, reducing reliance on traditional power sources. It also provides advanced features that enable it to maximize your solar power production and reduce your electricity bills through net metering.
Prioritizing Solar Energy: The inverter uses alternating current (AC) to power appliances in your home, which is more stable over long distances and avoids energy losses that occur with direct current (DC). This reduces your reliance on the grid during periods of low solar generation or high electricity demand.
UPS Mode: During an extended power outage, the inverter switches to UPS mode to activate your batteries and provide immediate backup power support for your critical equipment. It then regulates the voltage output to ensure a steady and reliable power supply.
When the grid comes back online, the inverter returns to its normal grid-connected operation of drawing power from both your solar panels and the electricity grid and charging the battery for future standby needs. This smooth transition minimizes disruptions and provides peace of mind.
Grid Backup
In a grid-tied hybrid inverter, your renewable energy sources and the grid work together. The inverter converts the DC electricity from your solar panels and battery storage into AC electricity for household appliances. It then sends excess electricity to the utility grid or uses it to charge your batteries if necessary. Some hybrid inverters come with a maximum power point tracker (MPPT), which automatically adjusts to the best voltage for charging your batteries.
The inverter can also operate in an off-grid mode, which disconnects from the utility grid and relies on your battery storage system or a gas generator for power. This can be especially useful in places prone to load-shedding and other power outages, where it ensures your essential loads have backup power.
A grid-tied hybrid inverter with a backup battery includes all the electronics needed to connect your solar system to the grid and provide back-up power. They can do everything a standard inverter does and enable you to participate in net metering, so you can receive credits from your electricity provider for generating power during the day.
Efficiency
One of the key reasons hybrid inverters are an excellent choice for a solar power system is their efficiency. They can optimize energy management and storage with features like battery storage, smart energy management, grid connectivity, and energy monitoring and control. Together, these features enable users to maximize renewable energy utilization while reducing reliance on traditional electricity sources and minimizing energy costs.
Hybrid inverters convert DC electricity from the PV array into AC electricity for household use. They can also send excess electricity back into the grid (via a net meter) or to charge the batteries. During peak usage periods, when electricity is most expensive, a hybrid inverter can switch to the grid to operate appliances and systems, then automatically shift back to batteries or solar energy storage for operation at off-grid times.
The hybrid inverter’s battery management and backup functions provide significant economic benefits to residential, commercial, and industrial customers seeking to reduce their energy costs and enhance charger their commitment to sustainability. In addition, the ability to participate in net metering programs increases financial savings and potential income.
Monitoring and Control
When it comes to powering your RV, boat or off-grid rig, a hybrid inverter unlocks the full potential of your solar system and battery by combining multiple power sources into one single stream. This helps to prevent power cuts caused by grid instability or other factors, keeping your vital systems running without blowing a fuse or overloading your generator.
It also prioritizes solar energy to ensure a reliable supply of electricity for connected appliances and equipment, even during periods of low solar generation or high energy consumption. Its peak shaving and valley fill mode utilizes PV + battery to prioritize power supply to loads and sell excess energy back to the grid (at this point, the batteries are in a discharged state). This reduces reliance on the grid and electricity rates while maximizing self-consumption of renewable energy.
Look for hybrid inverters that feature remote monitoring and control capabilities through mobile apps or web interfaces, enabling you to track energy generation, consumption, battery status and more from anywhere in the world. Additionally, consider those that are designed with scalability and expandability in mind, allowing you to upgrade your solar PV array and/or battery capacity without replacing the inverter.
