A solar inverter is a device that converts the direct current from solar panels into alternating current, which we use to operate everyday electrical devices such as vacuum cleaners, televisions, lamps, ceiling fans, air conditioners or heaters. An inverter is of course the main part of the solar power system that we install in our homes. We can’t run all devices with direct current and it gives us more usable energy, so we need an inverter. It is also known as the brain of the solar system.
Types of solar inverters
However, you should select the type of Solar Inverter according to the load and available space for a solar system. Here we are going to discuss the solar models to help you understand how they work and to help you install the appropriate solar inverter.
There are three basic models to understand the solar function.
- Network connected
- Off-grid system
- Hybrid system
On-grid inverters are solar inverters with MPPT controllers that are also connected to the public grid. The inverter can feed additional electricity into the grid and at the same time switch off the solar system in the event of a power failure in order to avoid phase shifts and other safety problems.
An on-grid inverter, which maps the energy supplier’s network according to production and consumption, effectively and intelligently manages the energy supplied by the panels and the backup system.
It is designed to work on its own, using off-grid solutions for homes in remote areas with no access to electricity.
In short, a pure sine wave is a repetitive vibration that flows in smooth, arcuate waves that is closest to the flow of electricity in a distribution network. In the case of square and thick waves, the modified sine wave is sent to the devices in the house.
Pure sine wave inverters are recommended for home appliance safety and performance because the modified wave does not carry electrical power as smoothly.
Hybrid solar inverter
These inverters combine inverters and solar batteries into one unit. Some hybrid inverters offer both grid-connected and off-grid functionality. You can use the energy generated by the panels yourself, feed it into the public grid or store it in batteries for later use.
The right inverter for your home
If you are considering purchasing a high performance inverter for a large home that consumes 2,000 watts (2 kW) of power on average, keep the following considerations in mind. The main thing people are looking for is usually solar inverter prices in India and then choose the best inverter that they can afford at a reasonable price. The types should be PWM and MPPT. The power suitable for solar inverters is 1kW, 2.5kW, 3kW, 5kW, 7.5kW & 10kW. The recommended batteries are 12V, 24V, 48V, 96V, 120V.
Properties of solar inverters
- MPPT – An MPPT inverter is usually a better choice than a PWM inverter as it charges the battery 30% faster.
- LED signals that indicate in most inverters whether the inverter is switched on, switched off or in standby mode. At the same time, a digital display can provide information such as the amount of energy generated by the panels or the hours in which the solar system generates electricity.
An LCD display helps homeowners understand inverter performance, including real-time monitoring of power generation, consumption, battery charge status and the causes of inverter failures.
- The latest trend is to remove the LCD, settings, and controls from the program on your phone or laptop. In addition, most inverters have the ability to collect data and instantly transfer it to your computer for easier viewing.
- Cooling system- If the inverter is placed outdoors in the above scenario, it can overheat from the sun and the operating process. A well-designed, efficient cooling system is crucial.
If the inverter has WiFi access, all functions of the LCD display can be monitored, managed and serviced online with the mobile app.
- Bypass switch – if an inverter fails, the power supply to the house is disrupted; However, a bypass switch enables homeowners to use electricity even if the inverter fails.
- MCB protection: An MCB protects the inverter from high voltage and short circuit failures caused by constant voltage changes in the grid current and the possibility of a short circuit.
Price for solar inverters in India 2021
A solar inverter accounts for around 25-30% of the total costs of a solar system. The highest solar inverter cost in India is listed below. Depending on the technology used, e.g. B. off-grid, grid-connected or microinverter, the cost of a solar inverter can be between 6 INR and 20 INR per watt.
Inverter technology, efficiency, warranty duration and brand quality are all aspects that affect the prices of solar inverters.
Efficiency, maintenance and guarantee
Since the solar inverter is an electronic component, it must be kept dry and free of dust. In the event of power fluctuations, a short circuit or failure of the inverter, only the top manufacturers can repair and service it. Various factors affect the longevity of the inverter, including the solar battery. Therefore, choosing the right battery is crucial. The capacity of a solar battery is measured in amps per hour (Ah), a measure of how long a battery can provide power to household appliances.
Off-grid inverters have efficiencies of 80 to 87 percent, grid-connected inverters efficiencies of over 97 percent. Off-grid inverters in India are only protected for 1-2 years, while grid-connected inverters are protected for up to 5 years.
The market is inundated with alternatives when it comes to choosing the right product for your needs, which can make it difficult. Loom Solar hopes that the information on this page will help you make a more informed decision about which inverter is best for your solar panel system.
