5kVA Solar Inverter Price for Home 2022: Working, Types, and Pros & Cons

Solar inverters are essential parts of a solar energy system. A solar inverter converts the energy produced from solar panels into usable power for commercial or domestic usage. 

The efficiency rating of an inverter (including other electrical appliances) is measured in Voltage and Current (VA). A 5kVA inverter is useful for converting direct current to alternating current, which can be used for various applications. 

The 5kVA solar inverter can provide a power of 4KW, that is 4000 watts.  Let us understand how a solar inverter works and the distinctive features of a 5kVA inverter, its price, and other beneficial details. 

How Does A Solar Inverter Work?

Working of Solar Inverter

Solar panels generate Direct Current (DC) by using electrons that move from the negative to the positive terminal. On the other hand, most appliances (including the power grid) that we use at home or offices run on Alternating Current (AC). 

AC power is the standard current that is utilised by power appliances and devices. Since solar panels only generate Direct Current, a 5kVA inverter is required to convert the Direct Current to Alternating Current. 

When the sun rays are transmitted on the solar panels, the electrons within the solar cells start moving, consequently generating DC power. To convert this power into usable energy, it is then transmitted to a solar inverter which converts it into AC power. After this power conversion, a solar inverter sends it to the power load to which it is connected. 

Different Types of 5kVA Inverters 

Listed below are the three types of solar inverters:

1. Off-grid inverters:

An off-grid 5kVA inverter is known as a solar battery or stand-alone inverter. This inverter is not connected to the power grid and does feed electricity into the grid. 

The solar panels are typically connected to a solar battery, which is then connected to an off-grid inverter in a solar panel system. 

2. On-grid inverters:

An on-grid 5kVA inverter, also known as a grid-tie or grid-connected inverter, is a device that connects a solar panel system to the grid. 

The excess electricity generated by the solar panel is automatically sent into the utility grid via a bi-directional metre by this inverter. In the event of a power outage, on-grid inverters have the capability of shutting down the solar panel system. 

3. Hybrid inverters:

A hybrid 5kVA inverter combines both on-grid and off-grid inverters into one unit. It is a multi-purpose inverter that supplies power to the appliances, charges the solar battery, and feeds excess power into the grid under normal operating conditions. 

In the event of a power outage or if the panels cannot meet the load, the unit will automatically switch to battery power and operate independently of the power grid. 

Technologies of Solar Inverters 

The power output of a 5kVA inverter varies with parameters such as how much sunlight it gets. Based on the size, different technologies are employed to enhance the efficiency of the solar inverter.

  • Pulse Width Modulation (PWM) – This technology is ideal for small-sized inverters with a maximum output efficiency of less than or equal to 70%. 

Solar inverters backed with this technology are economical to purchase; and thus, are suitable for solar panel systems employed for domestic or low-scale purposes. This technology may not work efficiently when the solar panels get covered in the shade.

  • Maximum Power Point Tracker (MPPT) –  This is a charge controller technology that is used to harvest the maximum possible energy from the solar panel under ideal conditions. 

It is a relatively expensive technology but provides an efficiency of 95-97%. All the grid-connected 5kVA inverters are manufactured using this technology.

Features of a 5kVA Inverter 

  • High Efficiency: 5kVA Solar Inverters are significantly more efficient than conventional inverters. These inverters can have an efficiency of 96% to 97%. 
  • Advanced Technology: The 5kVA inverters usually feature MPPT or PWM technology. Both these technologies have a long track record of success. An MPPT inverter is always a good choice because it charges the battery 30 percent faster than a PWM inverter.
  • Strong and sturdy: The 5kVA Solar Inverter is made of high-quality materials that ensure durability. They are also light in weight, which further facilitates easy transportation.
  • LCD display: An LCD helps homeowners understand inverter operations. It provides real-time analysis of power generation, consumption, battery charging status, and the cause of inverter failure.
  • Bypass Switch: When an inverter fails, the power supply to the home is disrupted; however, a bypass switch allows homeowners to use electricity even if the 5kVA inverter is malfunctioning.
  • Enhanced Levels of safety and protection: These inverters have all the necessary safety features. As grid power has constant voltage fluctuations and the potential for a short circuit, an MCB protects the 5kVA solar inverter from high voltage and short circuit failures.

Product Specifications Of A 5kVA Inverter 

The 5kVA solar inverter produces output that is entirely stable and distortion-free. This solar inverter is built using MPPT technology to enhance its efficiency.  

It is a microprocessor-based device that controls motor speed or voltage to provide power to the electrical appliances. The 5kVA inverter has an LCD that can be monitored through a mobile app. 

The inverter is easy to operate, requires minimum maintenance, and is completely safe for sensitive electrical equipment. 

The high efficiency of the 5kVA inverter makes it ideal for heavy-duty commercial applications. It is easy to install and features an extended power backup time. 

Since it is an electrical device, it should be kept away from dust and water.  Because the current from solar panels is variable, it cannot be used to charge the batteries directly. 

As a result, a solar charge controller is used to regulate the current received from solar panels and, ultimately, charge the batteries.

Technical Specifications Of A 5kVA Inverter 

When it comes to a good 5kVA solar inverter, there are a few things to look at from among the different inverter brands. These factors include 5kVA solar inverter price, types, size available, and ratings, among other things. 

It’s best to get an inverter that can handle the maximum power a solar power system can generate. You must ensure that your inverter’s kilowatt rating is equal to or greater than the output of your solar panels. 

If the solar inverter is weather-proof, you’ll have a little more flexibility in terms of placement, but if it’s not, you might want to consider investing in a weather-proof cage (that will cost extra).

Prices Of 5kVA Inverters In India 

The cost of a solar inverter is roughly 25-30% of the total cost of a solar panel system. Solar inverter prices are influenced by several factors, including inverter technology, efficiency, warranty period, and brand quality. 

The overall 5kVA inverter price also includes transportation, installation, net metering, and all additional expenditures. 

Investing in a solar inverter might seem an expensive move initially, but it is worth the cost in the longer run. The 5kVA solar inverter price varies according to the specification of the inverter. 

A normal inverter is a non-solar inverter with a starting voltage range of 650VA to 1800VA and a price range of ₹ 3,500 to ₹ 9,500, depending on brand, performance, and warranty. The overall price of a solar inverter ranges from ₹7,000 to ₹ 1,50,000.

The Difference Between 5kVA Solar Inverter And Normal Inverter 

A solar inverter is simply an upgraded version of a standard inverter that is far more efficient. One of its distinguishing characteristics is that it can function as a standard inverter, whereas a standard inverter can never function as a solar inverter. 

Here are some of the basic differences between a solar inverter and a normal inverter:
