A detailed guide on solar inverter 10Kva: Working, Types, and More

A solar inverter is a crucial electronic device that plays a major part in a solar system. It converts the electricity produced by the solar PV panels, i.e., DC (direct current) electricity, into AC (alternating current) electricity. 

AC electricity is utilised to supply power for domestic applications.

Earlier, these inverters were only box-like devices converting DC power into AC power. But, solar inverters have become more advanced and smart devices now. They can perform various additional functions like data monitoring, utility controls, etc.

Let us explore various aspects of solar inverter 10kva: its features, uses, specifications, and a lot more. Dive in! 

Working of a 10Kva Solar Inverter

A solar inverter 10kva takes DC input voltage and gives out AC power supply. This inverter may be a three-phase inverter or have a single-phase output AC supply.  

Types of a Solar Inverter 10kva

There are three types of 10Kva solar inverters. Let us learn about them in detail. 

• String Inverters: String inverters are devices that connect to a string of rooftop solar PV modules. There’s one inverter/array.  

• Micro Inverters: These solar inverters are connected directly to an individual solar panel to transform DC power into AC. What we mean is, that there’s 1 inverter/panel. So, if your array has 10 panels, there will be 10 microinverters. Micros are also considerable options for solar panels mounted on complex rooftops. They offer high efficiency; hence, naturally, they’re slightly expensive. But they’re totally worth the price. 

• SolarEdge Optimizer: The SolarEdge Power Optimiser is a solar inverter that is attached to all PV panels in a solar array. It turns each solar panel into a smart panel. Remarkably, by utilising the Maximum Power Point Tracking (MPPT) technology, these power optimisers enhance the power yield of the solar system. 

Technologies of 10Kva Solar Inverter Types

Do you know how the solar inverter 10kva functions? Let us understand the technologies that form the foundation of its mechanism.

• PWM Solar Inverter Technology – The solar inverters that work on PWM (Pulse Width Modulation) technology are known as PWM solar inverters. These inverters give a steady voltage output, irrespective of the load. However, PWM technology has become obsolete now.

• MPPT Solar Inverter Technology – The MPPT (Maximum Power Point Tracking) technology solar inverters are currently the best solar inverters in the market. These offer the highest efficiency, ranging from 95% to 97%. 

Remarkably, almost all the high-efficiency grid-connected inverters embrace the MPPT technology.

Difference between 10Kva Solar Inverter and Normal Inverter

One question that many people have is what is the difference between a 10Kva Solar Inverter and a normal inverter? Here are some key differences between both.

Normal Inverter	Solar Inverter
Adding a battery is necessary for a normal inverter, as it does not function without a battery.	A solar inverter can operate with a battery as well as without a battery.
It can supply about 230 Volt AC power to the home via the battery when the power fails.	It can supply about 230 Volt AC power to the home from a battery as well as solar panels.
An inverter charges the battery from the Grid power.	A solar inverter has a dual facility to charge the battery from Grid Power as well as the solar modules.

Did you know that any normal inverter can also be converted into a solar inverter via solar conversion kits?

Pros and Cons of 10Kva Solar Inverter

Conclusion

A solar inverter is one of the significant components of the solar array. It functions to convert solar energy into more useful electrical energy. Due to this fact, a solar inverter is referred to as the brain of a solar array. 

A solar inverter 10kva plays a crucial role in a solar system as the energy from the sun cannot be used to directly operate electrical appliances. 

Hence, a feasible inverter should be preferred that offers high efficiency and suits your requirement.

FAQs

Q1. How to install a solar inverter 10kva?

To install a 10Kva solar inverter, you will be required to connect your solar inverter with your batteries.
