A Solar Inverter is a device that converts the direct current (DC) from the solar panels into alternating current (AC) which is used by domestic and commercial appliances. It is one of the most critical components of the solar power system as it converts power from the sun into more useful energy and is often referred to as the brain of a solar system. Solar inverters are a crucial part of a solar system since power from the sun cannot be directly used to run electrical appliances. Starting out as just boxes converting DC into AC, today, solar inverters have evolved to become much more smart and intelligent units, performing other functions such as data monitoring, advanced utility controls, etc. Quick Links What is an Inverter?

A much-known function and description of the inverter is to convert the DC into AC by using an SMPS module or thyristor-based pulse converter technology. The converted DC to AC by inverter will run all the electrical appliances in the house after the power goes out. Solar Inverters in India are mostly imported through a few domestic and international manufacturers that have set up manufacturing operations in India. String inverters can be used for both rooftop and utility solar, while the central inverter is used exclusively for utility-scale applications. Microinverters are the best option for residential solar but they are not yet very popular in India. What is 'VA' in the inverter? VA defined the rating of Inverter. Most of the electrical rating is defined in terms of voltage and current (VA) because of AC power factor of current is decided by the load connected. AC Power = V X I X pf. Since the load power factor is not known while the Electrical equipment is manufactured, that’s why the rating of the Transformer and other equipment is defined in VA instead of Watt. Inverter Market Size & Trends In India, approximately 1 crore inverters are sold every year in India. Inverters are being sold which have both normal inverters and solar inverters. A normal inverter means that it will be used for charging of the battery by using electricity only, whereas a solar inverter has the facility of both electricity and solar charging of the battery. What is the Requirement of a Solar Inverter? We are all aware of the use of electricity nowadays & it’s an important part of our life. We are using Grid Electric Power supply provided by the Government or by some Private agencies in multistoried apartments. In India due to frequent power supply interruptions/cut generally, we are using a Diesel Generator set and Inverter as Backup Power supply at home as well as in industries to avoid shutdown conditions. Nowadays’s Solar is one the best options as a Main or Backup power supply for home & small-scale Industries and one of the best options for Ruler areas where the electrical power supply is irregular very much. How to Select the Best Inverter for Home? While you are planning to buy a heavy capacity inverter for big homes where the average power consumption is 2,000 watts (2KW), below are the main decision-making factors, you should keep in mind. Technology - Normal Inverter & Solar Inverter Type - PWM & MPPT Capacity - 1kW, 2.5kW, 3kW, 5kW, 7.5kW & 10kW Battery Support - 12V, 24V, 48V, 96V, 120V Features - Digital Display, IoT Based Pricing - Starts Rs. 7,000 to 1,00,000 Brand - Luminous, Microtek, Smarten, & Loom Solar Service - On Door Service Reviews - 4.4 Starts How does Inverter work? An inverter is like a converter of the power supply DC power into the AC power supply. It will take 110V / 220V DC input voltage and convert it into an AC power supply of 230V, 50 Hz. The inverter also may be a phase or phase output AC supply type and also can operate under & voltage conditions up to a range of a minimum of 190V and a maximum of 250V for a single phase Inverter. A Full bridge or Six-pulse converter is used to convert DC voltage into AC voltage The device can produce output voltage, and frequencies are controlled by the inversion process & the output voltage is connected to a transformer matching system it is feeding power into. Thyristor bridges are designed with a combination of diodes/rectifiers in forwarding & revere mode or blocking mode. If you have brought a normal inverter for your home, then your inverter will charge the battery with electricity only and bypass the supply to the home appliance. But when the power supply goes off then the inverter will feed the supply in your home appliance with the help of a charged battery. Now if you have brought a solar inverter to your home, then your inverter will provide a power supply to your home appliances during the day as well as charge the battery with the help of solar modules/ solar plates. During the night the inverter will charge your battery with electricity and bypass the supply for home appliances but in case of power supply goes out then your charged battery will take care of your home load with the help of an inverter. Types of Solar Inverters Based on the required load and space availability for the Solar System, you can choose the Solar Inverter. There are the following Solar models described here to understand the working function & that will help you to choose or invert the solar inverter. Three models are there to understand the solar function. Grid-Interactive/ Connected System Off-Grid System Hybrid system Inverters can be broadly classified into three major types: i) Off-grid/ Standalone inverters– work independently off the grid and require battery storage ii) On-grid/ Grid-tied inverters– are dependent upon the grid iii) Hybrid inverters – incorporate both battery and grid connection and have an inbuilt solar charge controller Grid-tied solar inverters are further categorized into micro, string, and central inverters. 1. Grid interactive/ connected system The most common, low-cost, economical, and better operation we use the Grid interactive/ connected system. This system will operate only when both solar and grid power is available & the first load feed from solar & balance will be imported from the grid. If case of excess solar power is either exported or trimmed (No export). Based on the application of both the supply one as Main & other as Backup or as load sharing depending upon the conditions. CONDITION-1 PV /Solar available & Grid available PV Energy Load Requirement Load supplied through PV Energy In that case, both supplies available and solar-generated power is greater than the required Load that the complete load will feed through PV and excess supply will trim or feed to the grid. CONDITION-3 PV Not available & Grid available Load supplied through Grid Energy In that case, PV/Solar Power is not available (during bad weather, at night duration, or due to maintenance of the PV System), and then the complete load will feed through grid power. CONDITION-4 PV is Not available & Grid is not available & Emergency DG is available Load supplied through Emergency DG set This is the case in which electricity very essential like hospitals, offices, banks, hotels, multistory apartments, etc. and PV/Solar Power and grid power are not available then an emergency Diesel Generator (DG Set) will feed to complete the load. Advantages of Grid-Interactive/ Connected System The most commonly used and adopted model by the customer due to the working philosophy You can make money by through off the generated excess power to the Grid/Government Low Investment Cost Will cuter the complete load during the office's peak hours Grid supply available as Backup in case of nonavailability of PV Storage Battery Not required No maintenance cost Low Generation losses Payback time is good it will return the total investment cost within 3 to 4 years (approx.) The drawback of Grid-Interactive/ Connected System Cannot store the electricity for the duration of nonavailability of PV/ solar. Required grid power supply during unavailability of the PV system (like during the night, or rainy season. 2. Off-Grid System This is a battery-based system, and grid supply is not available this is used for remote areas or in locations where grid supply is not available as a Backup supply during the night hours or rainy season. This is used for battery charging & load sharing during the availability of the PV system & feeds load through the charged Battery during the unavailability of the PV system refer to the below diagram. Case –I During the availability of PV/solar system Battery will charge with the parallel power supply to loads as shown in the below diagram with the flow of energy power. Case –II During the unavailability of PV/solar system Battery will feed to loads as shown in the below diagram with the flow of energy power. The drawback of Grid-Interactive/ Connected System The investment cost is High due to the use of Battery Not able to cuter the complete load during unavailable of PV system, generally Battery capacity design based on the Three (3) hours Backup as per IS/IEC standard. However, we can increase the backup time duration by increasing the capacity of the battery but it will impact the total investment cost. Grid supply not available as Backup in case of nonavailability of PV & Battery system Maintenance costs are high due to the Battery Generation losses are higher as compared to Grid-connected systems. Payback time is long will take time to return the complete investment cost. Required additional space and closed room for battery storage The small scale used only 3. Hybrid System This is similar to the Grid-connected Model, In which multiple sources of supply such as solar/PV, Grid, Battery Storage, DG set, Hydro plant any other power source connect parallel to feed load. This is a complicated system and is not used at the domestic level. Synchronization is required between all connected systems and loads. Inverter Vs Solar Inverter Inverter Solar Inverter The Inverter does not work without a battery, adding a battery is a must It has dual-use 1) It can operate with a battery and 2) without a battery It supplies 230 Volt AC power to the home from the battery when power fails It supplies 230 Volt AC power to the home from a battery and solar panels both It charges the battery from Grid power, It has a dual facility to charge batteries 1) Grid Power and 2) solar Panels Highest Power rating Home Inverter 10 KVA Highest power rating home Inverter 100 KVA PWM Vs MPPT PWM Solar Inverters – The smaller rating inverters less than 2 kW to be used in Rural areas and to make it affordable, it is made with PWM (pulse width modulation) technology. MPPT Solar Inverter – It is the best charge controller technology with the highest efficiency between 95-97%. All high-efficiency inverters and grid-connected inverters are built with MPPT (maximum power point tracker) technology. An inverter built with MPPT technology takes 30% less time to charge a battery using solar panels. Criteria PWM MPPT Full-Form Pulse width modulation Maximum power point tracker Efficiency 65-70% 95 -97% Built with Off-grid Inverters Grid-Connected Inverters Cost Low High Features of a Solar Inverter MPPT – An MPPT Inverter is always a good choice as it charges a battery 30% faster compared to a PWM technology-built inverter. LCD- An LCD Screen helps Homeowners understand Inverter operations such as real-time analysis of power generation, power consumption, battery charging status, and reason for Inverter failure. Mobile App (IoT)- All the features available in LCD Display can be monitored, controlled, and serviced online through the mobile app if the Inverter has Wi-Fi functionality. By Pass Switch- When the Inverter fails, the power supply to the home will be disturbed, Bypass Switch allows homeowners to use electricity even if the inverter is faulty. MCB Protection: the grid power always has voltage fluctuations, and chances for short circuits, MCB Saves the Inverter from High Voltage and Short circuit failures. What is a Hybrid Solar Inverter? The technology of inverters in India has improved quite a lot since the arrival of new technology. Earlier, the batteries were charged up by the inverters and after a power, all the electrical appliances were run by the inverter battery such as lights, fans, coolers, TVs, refrigerators, etc. but due to extreme power cuts of long hours, the power backup of the inverter battery was 3 to 4 hours, which led to the invention of solar inverter and the ‘solar charge controller’ was built inside the inverter. However, the solar inverter was successful only in those areas where the power cut had a period of 7 to 8 hours. In those areas where the power cuts were frequent, the user wanted to decrease their electricity bills and needed power during the power cuts. For this problem, Loom Solar invented a ‘Hybrid Solar Inverter’, which decreased the electricity bills and provided enough power during heavy power cuts to sustain the electrical functions of a home or business. This hybrid inverter includes transformers, and MPPT solar inverter, which can work with maximum efficiency and is available with IOT (Internet of Things).
