What is a Hybrid Solar Inverter?

A hybrid solar inverter is the combination of a solar inverter and a battery inverter into a single piece of equipment that can intelligently manage power from your solar panels, solar batteries, and the Utility Grid  at the same time.

A traditional solar grid-tie inverter converts direct current (DC) electricity produced by your photovoltaic (PV) system into the alternating current (AC) electricity that powers your house, which also allows excess electricity generation to be transferred to the utility grid.

A battery inverter handles the process of inverting DC electricity that’s stored in your solar battery storage into AC electricity that can be used by your home.

By combining these functions into a single device, a solar hybrid grid-tie inverter streamlines and improves the operations of the classic solar inverter. Even better, since the amount of solar power that’s available can depend on the weather and seasonality, a hybrid inverter can draw power from the electricity grid to charge your battery storage system if needed.

What are the Functions of a Hybrid Solar Inverter?

The basic purpose of an inverter is the conversion of DC input from your solar panel into AC output that your home can use. The function of hybrid solar inverter use takes this process to the next level, including the following benefits:

DC-to-AC Bi-Directional Power Conversion: Normally solar batteries are charged by either DC electricity received directly from solar panels (DC coupled), or DC electricity that has been converted from AC electricity by a solar inverter (AC coupled). Then to release that power, an inverter needs to convert that stored DC electricity back into AC electricity.

With a hybrid inverter and battery, one device can do both roles. The hybrid grid-tie inverter can convert DC electricity into AC electricity to power your home, but it can also take AC electricity from the grid, and convert it into DC electricity that can be stored in batteries for later use.

Power Regulation: Solar power can fluctuate as sunshine levels increase and decrease, based upon the time of day and weather patterns. A hybrid inverter regulates this power to ensure the whole system operates within the required parameters.

Power Monitoring: Solar hybrid grid-tied inverters can be fitted with solar power monitoring software to measure and monitor your photovoltaics system via the display screen or a connected smartphone app to help identify any faults. 

Power Maximization: Hybrid inverters with Maximum Power Point Trackers (MPPT) check your solar power output and correlate it to the battery's voltage. This enables optimum power output and conversion of DC electricity to the best voltage for the battery's maximum charge. MPPT guarantees your solar power system works efficiently under every condition, such as varying amounts of solar light, solar panel temperature, and electrical loads.


Solar power has become an increasingly popular source of renewable energy in recent years. There are three main types of solar power systems: off-grid, on-grid, and hybrid. Each system has its unique features and benefits, making it important to understand the differences between them to choose the best option for a particular situation. In this article, we will explore the differences between off-grid, on-grid, and hybrid solar power systems, how they work, and their advantages and disadvantages.

1.On- Grid System –

On-grid solar power systems are a popular option for those who want to generate their electricity from renewable sources while still maintaining a connection to the national power grid. This type of system is also known as a grid-tied system and works in tandem with the local utility company or distribution company.

On-grid systems generate electricity from solar panels and use an inverter to convert the direct current (DC) electricity produced by the panels into alternating current (AC) electricity that can be used to power a home or business. Any excess power generated by the system is sent back to the national electric grid for compensation, which can be received through feed-in tariffs or net metering programs.

Feed-in tariffs involve receiving payment for the excess electricity that is fed back into the grid. This payment is typically based on the amount of electricity generated and can be a fixed or variable rate. Net metering programs allow homeowners to offset their electricity bills by sending excess power back to the grid, and the compensation they receive is calculated based on the difference between the amount of electricity generated and the amount of electricity used.

On-grid solar power systems are a cost-effective way to generate electricity from renewable sources because they eliminate the need for batteries to store excess energy. This means that homeowners can avoid the expense of purchasing and maintaining a battery bank while still being able to generate their electricity from solar power.

However, there are some disadvantages to on-grid systems. They cannot generate electricity during power outages, and they are reliant on the availability and reliability of the national electric grid. Despite this, on-grid solar power systems remain a popular option for homeowners and businesses looking to reduce their reliance on traditional sources of electricity while still maintaining a connection to the grid.

2.Off- Grid System

Off-grid solar power systems are a type of solar power system that operates independently of the national electric grid. This type of system is commonly used in remote areas that are not connected to the grid, or by individuals who want to reduce their reliance on traditional sources of electricity.

Off-grid solar power systems generate electricity from solar panels and store it in batteries for use when the sun is not shining. The batteries are connected to an inverter, which converts the DC electricity stored in the batteries into AC electricity that can be used to power a home or business.

Because off-grid solar power systems are not connected to the national electric grid, they require the use of batteries to store excess energy. This means that homeowners must purchase and maintain a battery bank, which can be expensive. However, the cost of the batteries is offset by the fact that off-grid systems provide reliable electricity even in remote areas that are not connected to the grid.

Off-grid solar power systems also require careful planning to ensure that the system is properly sized and that there is enough energy storage to meet the homeowner's needs. The system must be designed to meet the home's energy needs throughout the year, including periods of low sunlight and high energy demand.

Despite the initial costs and planning required, off-grid solar power systems offer several advantages. They provide energy independence, reduce reliance on traditional sources of electricity, and are a reliable source of electricity in remote areas. They also have a low environmental impact, as they do not emit greenhouse gases or other pollutants associated with traditional sources of electricity.

3. Hybrid System

Modern hybrid systems combine solar and battery storage into one unit and are now available in a variety of shapes and sizes. Because the cost of battery storage is decreasing, systems that are already connected to the power grid can begin to benefit from battery storage as well. This entails storing solar energy generated during the day and using it at night. When the stored energy runs out, the grid serves as a backup, giving consumers the best of both worlds. Hybrid systems can also charge the batteries using low-cost off-peak electricity (typically after midnight to 6 a.m.).

There are several approaches to designing hybrid systems, but we'll keep it simple for now.

  • The bank of batteries. Once the solar power is used by the appliances on your property, any excess power is sent to the battery bank in a hybrid system. When the battery bank has been fully charged, it will no longer receive power from the solar system. The energy from the battery can then be discharged and used to power your home, typically during peak evening hours when electricity costs the most.
  • The meter and the power grid. Depending on how your hybrid system is configured and whether your utility allows it, excess solar power not required by your appliances can be exported to the grid via your meter once your batteries are fully charged. When your solar system is not in use, or if the usable power in your batteries has been depleted, your appliances will begin drawing power from the grid.
  • What is the difference between a hybrid inverter and an inverter?

    A hybrid inverter is essentially a combination of an inverter, a charge controller, and a grid-tie function. The main difference between an inverter and a hybrid inverter is that a hybrid inverter can work with both renewable and traditional energy sources, while an inverter can only work with renewable energy sources.
