Types of Solar InvertersInverters can be broadly classified into three major types:i) Off-grid/ Standalone inverters – works independently of the grid and requires battery storageii) On-grid/ Grid-tied inverters – are dependent upon the gridiii) Hybrid inverters – incorporate both battery and grid connection and have an inbuilt solar charge controllerGrid tied solar inverters are further categorised into micro, string and central inverters.
History of Solar InvertersThe history of solar inverters in India can be tied up with the advent of solar panels in India. Though solar panels were used in small quantities earlier, it was actually after the Modi government at the Centre that solar technology became more popular in India. The success of solar can be measured by the eightfold jump in number of solar installations from 2.63 GW in 2014 to 22 GW currently.
Solar inverters are a crucial part of a solar system since power from 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.
Solar Inverters in India are mostly imported though a few domestic and international manufacturers have set up manufacturing operations in India. String inverters can be used for both rooftop and utility solar, while central inverter is used exclusively for utility-scale applications. Micro inverters are the best option for residential solar but they are not yet very popular in India.
Solar Inverters Price list 2019A solar inverter accounts for approximately 25-30% of total solar system cost. Given below are the price list of best solar inverters in India. The price of solar inverter per unit starts from INR 3,500 and goes up to INR 1,40,000, in terms of per watt price, Solar inverter per watt price varies from INR 6 - INR 10 per watt. There are multiple factors that affects price of solar inverters such as inverter technology, efficiency, warranty period and the quality of brand. below in the table, average price of solar inverter in India is listed:-

Solar Inverter efficiency & warrantyGrid Connected inverters have efficiency higher than 97% while Off Grid inverters, have efficiencies ranging between 80%-87%. In India, there is up to 5 years warranty on a Grid Tied inverter, whereas off grid inverters have for 1-2 year warranty.
Solar Inverter ComparisonThe major difference between a micro and a string inverter is that in case of an obstruction, only the individual panel is affected in case of micro inverter while the whole system is affected in case of string inverters. Also, micro inverters work at lower voltage when compared to string inverters.Source:- Loom Solar
