Solar panels are only one component of a home’s solar power system. Your home solar panels produce direct current (DC) electricity. Everything in and around your home runs on alternating current (AC) electricity. So, for the electricity from your panels to be useful your system needs an inverter. An inverter converts electricity from DC to AC.

Hybrid inverters do the work of a traditional solar inverter and a separate battery inverter, too. They’re a solution for homeowners who want to install a solar power system with a battery storage system either at the time of installation or in the future.
With this guide, you will learn the basics of hybrid solar inverters, how they function, how they compare to other types of inverters, what a hybrid grid-tied inverter does, and the pros and cons of including one in your home solar system.
A hybrid solar inverter takes the function of two other pieces of equipment — the solar inverter and battery inverter — and combines them in a single piece of equipment that manages power from your solar panels, solar batteries, and the utility grid with more efficiency at the same time.
A traditional solar grid-tied inverter converts direct current (DC) electricity produced by your panels into the alternating current (AC) electricity that powers your house. This kind of inverter sends excess electricity generation to the utility grid.
A battery inverter converts DC electricity 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-tied inverter streamlines and improves the operations of a traditional solar inverter. Even better, since the amount of solar power that’s available can depend on weather and seasonality, a hybrid inverter can draw power from the electricity grid to charge your battery storage system if needed.
The basic purpose of an inverter is the conversion of DC input from your solar panel into AC output your home can use. Hybrid solar inverters take this process to the next level.
Normally solar batteries are charged by 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). To release that power, an inverter needs to convert the stored DC electricity back into AC electricity.
With a hybrid inverter and battery, one device can do both roles. The hybrid grid-tied inverter converts 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.
Solar power fluctuates as sun levels increase and decrease. A hybrid inverter regulates this power to ensure the whole system operates within the required parameters.
Solar hybrid grid-tied inverters can be fitted with solar power monitoring software to measure and monitor your system via the display screen or a connected smartphone app to help identify any faults.
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 system works efficiently in every condition, such as varying amounts of sunlight, solar panel temperatures, and electrical loads.
A grid-tied hybrid inverter allows for a seamless merger between your home’s solar power system and the electricity grid. Once your solar array generates enough power for your home, you can use excess electricity to charge your solar battery system and transfer the rest to the grid after your battery storage is fully charged.
What makes the hybrid inverter stand out from other central inverters is its bi-directional power transfer ability. As we discussed earlier, a battery inverter converts between AC and DC power for storage, while a solar grid-tied inverter manages the relationship between the home, the home’s solar power system, and the electricity grid. (There are three primary versions of solar inverters: https://palmetto.com/solar/microinverters-vs-string-inverters-pros-and-cons-guide.)
The hybrid inverter does all of this and can also use AC power from the grid to charge your solar battery storage if the energy from your solar panels is inadequate or being used to power your home.
There are a few key advantages with a hybrid inverter, whether you get a battery now or are considering one down the road.
Having a solar power system does not always guarantee you will have power during a power outage. If your system uses a traditional solar grid-tied inverter, it will automatically shut off power from your system during a blackout for safety purposes.
A hybrid inverter paired with a solar battery storage system is a great solution for such a scenario. It ensures you have both off-grid and on-grid capabilities, so you always have access to power, even during a blackout.
A full solar power installation can be a significant investment, especially if you add an energy storage system to the other individual components. A hybrid inverter is designed to integrate storage at any time, allowing you to forgo the costs of installing battery storage initially. You can more easily add the battery bank later while still enjoying the full benefits of your solar energy now.
A hybrid inverter simplifies energy monitoring because you can check vital data such as performance and energy production via the inverter's panel or through a connected smart device. If your system has two inverters, you have to monitor them separately.
There are a few cases where hybrid inverters may not be the best solution.
If you want to upgrade your existing solar power system to include battery storage, choosing a hybrid inverter could complicate the situation, and a battery inverter might be more cost effective. All you really need is an AC-coupled battery with its own battery inverter to expand your system. Since you already have a grid-tied solar inverter, choosing to install a hybrid inverter requires a complete and costly re-work of your entire solar panel system.
The initial installation of a hybrid inverter can be more costly than a traditional solar power inverter. If your area experiences frequent power outages and you want the option of adding battery backup in the future, having a hybrid inverter can be worth the higher cost.
However, if your power grid is reliable and you have access to net metering, a regular grid-tied system might be sufficient and would likely be less expensive than a hybrid inverter plus battery storage.
Solar battery design changes with advances in technology, and not all hybrid inverters work with every type of battery. If you install a hybrid inverter now with the idea you might add a solar energy battery later, your future options may be limited by compatibility. For example, some solar panel energy storage systems now come with built-in inverters, eliminating the need for a separate hybrid inverter altogether.

While a hybrid solar inverter is a larger initial investment, it can be worth the extra cost if you plan to include solar battery storage with your initial solar installation or shortly after.
A hybrid inverter helps manage issues like intermittent sunlight and unreliable utility grids, so it performs exceptionally well compared to other types of solar inverters. Better still, a hybrid inverter helps you to store energy for future consumption more effectively, including backup power to use during emergencies, power outages, or peak utility rate hours.
Hybrid inverters also allow for more efficient power generation and management, especially when it comes to being on the wider electricity grid and plans like net metering and time of use rates. Additionally, ultra-modern tech allows you to conveniently monitor and manage your solar power system from anywhere via connected smartphone apps.
Most home solar panel systems remain tied to the greater electricity grid, meaning they’re not truly off-grid. If you want to fully disconnect your home from the power grid, you must install enough battery capacity to power your home for days at a time, when your panels don’t generate enough electricity or there’s a grid outage. That’s often cost prohibitive for many people, though tax credits for batteries can help reduce the cost.
If you want to go off the grid, a hybrid inverter can help, because they are designed to complete multiple tasks as a single device, including solar panel operation, battery storage, and drawing electricity from generators and other sources of power.
Even with higher initial costs, a hybrid inverter can pay off in the long run by giving you a solar inverter that maximizes the operations of your solar system. A hybrid inverter can reduce your reliance on the grid, lower your carbon footprint, enjoy advanced monitoring tools, and enhance your power generation.

What is a hybrid solar inverter?
A hybrid solar inverter changes electricity from alternating current to direct current and back again, an important step in passing electricity between solar panels, backup batteries, your home, and the grid.
Is a hybrid solar inverter better than a conventional inverter?
A hybrid inverter is more flexible than a conventional inverter, but that doesn’t mean it’s better. If you’re planning on keeping your solar panels tied to the grid and don’t have plans for adding a battery, a hybrid inverter might not be ideal and would likely cost more.
What is the lifespan of a hybrid inverter?
Inverters typically have a shorter lifespan than solar panels. Most hybrid solar inverters can be expected to last 10-15 years.
Have you ever considered having a hybrid solar inverter installed in your home? If not, you could be missing out on significant savings each month on your energy bills. While just under 5% of the UK’s power is currently supplied via solar technology, it's a figure on the rise, and those who adopt it can look forward to protection from the energy insecurity that may become a reality in years to come.
Hybrid inverters sit at the very forefront of energy efficiency, blending the best of both worlds of solar energy and battery storage. This means not only harnessing the sun's energy to power your home but also storing excess energy for later use.
In this article, we take a look at what a hybrid PV inverter is, how much having one installed might cost, and what's involved in choosing the right hardware for your needs.
Essentially, a hybrid solar inverter is an innovative piece of hardware that excels in managing solar energy. Acting as a control centre for your entire solar power system, it efficiently takes the electricity gathered by solar panels and converts it from its unusable AC form into DC current.
