A hybrid inverter solar can be an all-in-one solution. This is a common question in the renewable energy industry because there are many products available in the ‘inverter’ category. The differences between products can relate to basic output wave technology, features and functionality. That means the differences create distinct manufacturing requirements and therefore varying pricing in the market. From standard solar PV inverters to hybrid solar inverters to battery inverters, the renewable energy market caters to all customer requirements.
Solar energy is gradually entering all walks of life as well as our home life. However, it is easy to see that for a solar system to work properly. The inverter is like the system’s brain. However, a hybrid inverter solar does not need an additional battery inverter. More importantly, we can use hybrid inverters even without batteries. Therefore, it is always difficult to choose from the wide range of inverters available in the market.
What is hybrid inverter solar?
A hybrid inverter solar (sometimes referred to as a multi-mode inverter) is an all-in-one solution that contains three totally different functions. It has an integrated mppt solar charge controller that connects to the solar panel(s) and serves to regulate the voltage from the output of the solar panel to the loads and/or batteries.
Utility power and generator power can often also be inputs for incoming energy.
A hybrid inverter offers multiple system design options, creating flexibility to implement the right solution for each customer’s conditions.
This product “inverts” the current from direct current (DC) coming from the solar panels, to alternating current (AC) so typical home and business appliances and equipment can operate. If approved in the local area, the utility grid can also use the energy created by the solar panels. This alternating current can normally be 50 or 60 cycles per second or Hertz (Hz), and as each cycle has a rise and fall, the AC current would pass by zero 100 or 120 times per second.
The hybrid solar inverter also serves as a battery charger, taking power from PV and/or an AC source to charge the batteries. The energy stored in the batteries can then be used later.
Inverter Types
Normal power inverter
A power inverter is mainly a device that converts DC power to AC power using switches, control circuits, and transformers. Every inverter, whether it is a solar inverter or a normal inverter, has this as its basic goal. A typical inverter transforms DC electricity from a battery to AC power for use in appliances.
Inverter batteries and inverters are usually connecting to your home’s power supply. Charging batteries when power is available from the grid or the network. The inverter immediately changes to battery mode when there is no power, allowing you to utilize appliances and other necessities.
Pros
- Stable system
- Cheap price
- Easy to install
Cons
- It Could have a best inverter battery for home storage. However, the system’s battery side needs a separate inverter.
- We might need a separate energy management system to maximize total system efficiency.
Hybrid Inverter Solar
The hybrid inverter solar is one of the most use widely inverters today. Its main function combines solar and battery inverters in one simple unit. Hybrid inverters have become cheaper with the advancement of hybrid technology. In comparison to solar inverters, these hybrid inverters are becoming more competitive. A hybrid inverter is a wise investment if you anticipate needing energy storage soon. Whether there is power or no power, it does not affect its operation.
Benefits
1. Intelligent monitoring system.
The monitoring function of the hybrid inverter makes it easier to understand the operating conditions of the inverter. Also, if the best inverter battery for home is connected, the hybrid inverter will work even if there is a power failure. This means that we can have conversations and do many interesting things with our cell phones. You can log into the app provided to you by the supplier to track the output of the system. And receive notifications when the system is not running properly and if it is.
2. High efficiency
What makes the hybrid inverter different from microinverters and string inverters, for example, is its high solar energy conversion efficiency. The sunlight is utilized to a great extent. Compared to string inverters, it is not affected by individual solar panels. Even if a single solar panel is not working, it does not affect the work of other solar panels. The hybrid inverter also has configurable modes that allow you to put the device on vacation or standby using an application.
3. Low maintenance and no pollution
The hybrid solar inverter does not require much maintenance from us later on. If there is a fault, our mobile app and the display of the hybrid inverter will give us the fault. Also, it is not using traditional coal, oil, etc., to protect the environment and reduce pollution.
Cons
- Less design flexibility compared to modular solutions using separate PV and battery inverters
- The efficiency of dedicated solar inverters or the best inverters for home use is often low.
Related Solar Hybrid Inverter
Hybrid solar inverters can categorized into four types based on their features and specifications.
Basic Hybrid Inverter
The basic hybrid solar cell inverter functions similarly to a grid-tied inverter. A fundamental hybrid inverter’s lack of grid separation is its biggest drawback. This implies that it is unable to provide power to your home in the event of a power outage. As a result, only dependable grid supplies make the basic hybrid inverter a wise choice.
Battery Hybrid Inverter
Battery inverters, also called multi-mode hybrid inverters, are an advanced solution. This hybrid inverter can provide backup power when needed. Hybrid inverters are available either as built-in units or as separate units. These hybrid inverters can power your home, charge batteries, and provide surplus power to the grid. If the grid fails, the unit will switch to battery power and operate independently of the grid.
All-in-one hybrid energy storage systems
Modern hybrid inverters frequently include a best inverter battery for home system as a whole. A battery energy storage system is what such a device is known as (BESS). It can install in your house using a solar system that is already there. These hybrid systems come in a variety of shapes and configurations.
AC-coupled hybrid and off-grid systems
Usually, separate inverters are part of hybrid systems. They combine to create an AC-coupled system. Such systems usually have a standard solar inverter as well as an interactive or multi-mode battery inverter. The multi-mode inverters act as battery inverters to complete the energy management system and optimize energy use with the help of software.
Battery inverters
Battery inverters are like other inverters in that they work to convert DC power to AC power. But they also perform the opposite operation – converting AC power to DC power in order to charge a battery bank. Homes without solar PV systems can still install battery inverters. The batteries are charged by using cheap off-peak grid power. However, they are more frequently placed in ordinary homes in order to collect and store extra solar energy.
Advantages of battery inverter
- Modular nature brings greater flexibility to system design
- Most installations are particularly tough since they have a long history of use in off-grid and standalone power systems.
- Can be retrofitted relatively easily to existing solar PV systems to increase battery storage
When to use a hybrid inverter
If the power system is going to use AC loads, 120 (110-130) Vac or 230 (208-240) Vac, then a hybrid inverter is important. Since it can work completely off the grid, it can sometimes work with or without batteries. And even with or without solar panels a hybrid inverter is a very flexible solution.
This hybrid solar inverter can connect to the utility grid with possible injection to the grid (depending on local permissions) if desired.
So, for example a power system can be installed, when only a utility grid connection, PV and AC loads, while a battery can be added a few years later when more capital is available.
In any case, it is more efficient to use a hybrid inverter versus two separate pieces of equipment, that is solar charge controller and inverter, but the hybrid inverter should set many parameters. Inverters and charge controllers sold separately have fewer parameters to be modified and must be wired and programmed to work together.
Hybrid inverters also avoid duplication of components when compared to discrete solar charge controllers and inverters, reducing their cost considerably. The ability of hybrid inverters to automatically synchronize their own inverter to an AC source before switching AC loads between these two sources also avoids damage to AC loads due to sudden voltage swings.
With or without solar panels, these inverters are incredibly adaptable. In some cases, if you can’t afford solar cells, some manufacturers allow these inverters to connect to the grid and connect to home Wi-Fi, allowing for remote modifications.
Can hybrid inverter work without batteries?
Yes. Due to its structure, the grid can connect to a hybrid inverter. The energy collected by the solar panels is converted by the inverter and stored in the grid. This is convenient for use in case of a power outage need. When the sun is out, you can also connect the appliance straight to the inverter.
How to choose the suitable solar inverter
Now, if you are not sure which a best inverter for home to buy or you are not sure how to buy one. Then I will give you a preliminary process next. Of course, it is essential to listen to the supplier’s advice on the solar inverter you are buying. After all, they are professionals and will give you a better solution.
Step 1: Determine the total power
Note that this does not mean that you have to calculate the total power of your home load precisely. We need to calculate an approximate value roughly, and then when buying the best inverter for home, you need to choose if it is 1.2-1.5 times the household’s total power. This will not result in insufficient inverter power, nor will it result in wasted too much power.
Step 2: Check the VA rating
Our next step is to purchase an inverter with the proper volt-ampere (VA) rating, which indicates the voltage and current that the inverter provides to the appliance. So, how do we decide how much VA is needed to meet our power needs? VA = Power Demand/Power Factor. The power factor is simply the ratio of the power required by the appliance to the power supplied by the best inverter for home. The average power factor of an inverter is 0.7 or 0.8 or 1.0. If VA = 1600 W / 0.8 then VA = 2000 approx. Therefore, in our case, we should look for an inverter with about 3000 VA.
Step 3: Find the correct battery
The correct battery is the backbone of the best inverter for home. It holds the performance and lifetime of the inverter. It also determines how long can use the inverter after a power failure. You can do this by taking advice from the solar inverter supplier.
