What is a hybrid solar inverter?


A hybrid solar inverter or hybrid grid-inverter is a battery-based inverter. Hence, it is a combination of both solar and battery inverters in a single device. A hybrid inverter indeed is an intricate component. It converts Direct Current into Alternative Current to run the home appliances.

Moreover, if you install solar panels with a conventional inverter system, you have to add a battery later. In addition, you need a separate system to convert the DC to AC; however, in the case of a Hybrid inverter, you will get them both in hand.

In a nutshell, a hybrid inverter has both battery system and convention inverter technology. Hence, it is convenient for the users to have all the facilities from a single device. Most importantly, hybrid inverters are specially designed to include a storage system.

How does a hybrid solar inverter work?

The primary job of a solar inverter is to convert DC power to AC power. However, Hybrid inverters have an advanced technology to go a step further. Hence, it is capable of working with batteries to store excess power. In other words, it can solve the issue of renewable energy and the unreliability of the grid structure.

  • Hybrid inverters are capable of storing power in batteries and use drawn-up power to stabilize the energy.
  • The performance of a hybrid inverter varies in size and features. However, a standard direction is given to convert the DC power into DC power.
  • On the other hand, Hybrid inverters can also remain grid-connected. Using renewable and non-renewable energies, it charges the built-in batteries and offsets load.
  • The smart hybrid combination can store the extra electricity in a solar battery. On the other hand, it is capable of exporting surplus energy back to the power grid.

As it is a fully automated and programmable machine, the manufactures can apply a custom engineering method to add more features. Based on the classification of the hybrid inverter, their work efficiency also transforms. So, we can have a look at the different varieties:

Basic hybrid inverter: it is almost like a grid-feed inverter. It allows storage capacity in a separate battery system. But, it doesn’t have a grid isolation device.

Multi-mood hybrid inverter: as the name suggests, it has an optimum power backup system. If grid operation fails, it has n automated function to operate independently.

All-in-one hybrid energy system: this system forms an advanced technique called BESS or Battery Energy Storage System. It is ideal for your existing solar energy power.

AC hybrid and off-grid systems: this system typically has a standard solar inverter system and a multi-mode battery inverter. It functions as a multi-mode inverter to complete the battery management system.

This classification would help you to opt for the right choice of the hybrid inverter. Likewise, you can try out a solar calculator to measure the required voltage capacity and energy efficiency.

What is the difference between a hybrid inverter and a normal inverter?

The next thing that comes to our mind is, how advantageous is a hybrid inverter? While installing a solar system in your house, you have two choices in hand. While standard inverter batteries come in suitable prices and generic features, the cost and functionality of hybrid inverters are comparatively exceptional.

Let’s find out what are relative strengths and weaknesses these two batteries offer:

Standard inverter

Standard solar battery inverters offer basic functions. Apart from its generic function, it doesn’t have any exclusive technology to offer. Even though the features and functions vary in different brands, it is widely used in the grid-connected solar system.

However, it is not capable of storing excess energy. Henceforth, users need to install a separate battery storage function. Without the additional output, you have to compromise the efficiency of the inverter.

Hybrid solar inverter

In contrast, hybrid solar inverters offer additional functions and features. It can manage the inputs from a solar panel and the battery bank at the same time. The functions go beyond the limited features of a standard inverter. Thus, it is an all-in-one solution for grid-connected and solar energy storage systems.

Moreover, by integrating intelligent and programmable functions, manufacturers can maximize their efficiency. On top of that, one can install the inverter without batteries for future expansion. 

In terms of functionality, it is way better than a general off-grid or standalone power system.

However, in spite of having so much advancement, a hybrid inverter has a couple of disadvantages.

Disadvantages of hybrid inverter

Hybrid inverters are not the right solution for all types of solar panels. In most cases, you can follow the listed disadvantages:

Incompatibility with a solar panel system

Do you already have solar installed in your home? It means you already have a backup system; however, you may be looking forward to modifying the system. Since the solar panels already have a grid-tie inverter, switching to a hybrid will require the re-installation of wiring. Hence, it will definitely cost more money and labour.

Cost of Equipment

 Do you witness frequent power outrage? In that case, installing a hybrid inverter is undoubtedly a good choice. However, if you don’t face power outrage, I think the hassle and cost of installing a hybrid inverter are not at all worthy.

Moreover, if the utility company of your area offers favourable net metering incentives, regular grid-tie panels would cost less upfront.

Hybrid inverters are not flexible

All hybrid inverters are not battery agnostic. When you can have a built-in battery backup system with a separate energy system, I don’t think you have the need to install a hybrid system altogether. Moreover, once you integrate a hybrid inverter, you are limiting future storage technology options.

Compare different inverter technologies to obtain the best option

Everyone wants to have the best option. However, they fail to understand the roadmap. If you want to land up for the best energy system option, you should always compare multiple options available in the market. Starting from service charges to other integral decisions, a well-researched decision is always good.

Look, you have potentials reasons to buy a hybrid inverter. Moreover, if you are not worried about the costing you only have the upsides. But, choosing the right hybrid inverter from the plenty of options can also be daunting! In that case, you should compare the functionality and durability of the best brands available in the market.

People also asked: 

What does solar hybrid inverter mean?

A hybrid inverter is A COMBINATION OF BOTH OFF-GRID AND ON-GRID SOLAR INVERTER. This inverter controls the solar panel arrays to store batteries and power grids at the same time.

What is a hybrid inverter with solar battery charging?

It consists of an inverter powered battery with 12V. This inverter can generate up to 110V Ac with delivery circuitry and a heavy load transformer.

Are hybrid inverters good?

IN TERMS OF PERFORMANCE AND EFFICIENCY, HYBRID INVERTERS ARE REALLY A SMART CHOICE. However, you might face some difficulties regarding compatibility and flexibility while integrating with your existing solar panels. 

Can a hybrid inverter work without a battery?

YES. IT CAN! IN FACT, IT IS ONE OF THE EXCLUSIVE FUNCTIONS OF HYBRID INVERTERS. IF YOU DON’T WANT TO BUY A BATTERY SEPARATELY, YOU SHOULD GO FOR A HYBRID INVERTER SYSTEM.
