Top 10 solar inverters in India
Rooftop solar PV has been gaining popularity in India recently. The ministry of new and renewable energy has actively been promoting the same with subsidies and easy loans. In addition, various states have also brought out various policies to this effect. Tamil Nādu for example provides a subsidy of Rs. 20000 per kW of grid connected rooftop solar PV in addition to central subsidies. These systems typically range from 2 kW to 5kW for the individual houses. On grid inverters are directly connected to the grid and feed the power generated from rooftop PV to the grid. Inverters are typically chosen based on their capacity, size, peak efficiency, and of course cost. This blog discusses the top 10 solar inverters for rooftop PV application in Chennai.

- SMA India
SMA is a German company with 40 plus years’ experience and global presence. They have their Sunny Boy (single phase) and Sunny Tripower (3 phase) series of string inverters available for residential customers with powers ranging from 1kW to 6kW. They also have proprietary software solutions like SMA Smart Connected, SMA Shade Fix etc. and integrated online communication portals for monitoring. Maximum rated input voltages and currents are in the range of 600V and 15A. Dimensions go up to are 435x470x176mm and weights up to 17kg. They offer a standard 5-year + additional 5-year conditional warranty based on models.
Sun grow as a company that has a 25-year of experience in solar products. They offer single and multi MTTP systems. Power ratings up to 9kW are available for residential applications. Higher power models are available in 3 phase configurations also. Maximum input voltage is 600V. Currents ratings are 16A per input. The systems have average efficiencies around 98%. Dimensions are around 410x270x150mm and 10kg for a 5kW system. They offer a standard warranty of 5-years.
- Solar Edge
Solar Edge is headquartered at Israel was established in 2006. The company has a range of string inverters. They have single phase solar inverters for residential applications from 2 to 6 kW and three phase inverters from 3kW and above. The peak input voltage can be as high as 900V, providing output around 200V (single phase) or 400 V (3 phase) ac at 50-60Hz with a peak efficiency over 97%. With dimensions of 540*3158191 mm and weighing around 16kg, these systems provide 12–25-year warranty options, making them extremely attractive for reliable operations.
Unlike most of the inverters discussed so far, Enphase specialises in micro inverters of around 250W peak output. However, multiple inverters can be utilised if larger power output is required. Maximum input volage is a low 48V when compared to its larger counterparts, and output is single phase 240V AC. Peak inverted efficiency is 97.6%. Enphase claims that modular systems employing multiple microinverters minimise safety hazards due to lower voltages and isolate faults to single units instead of affecting the entire panel configuration. The system also provides data to the user through an android app, allowing for intelligent energy utilization.
- Fimer (ABB is fimer now)
Fimer, which recently acquired Abbs’s inverter manufacturing, is a major player in the solar inverter space. The company supplies both single and three phase. These smart inverters typically range from 1.2 to 6 kW and can transfer data to user via ethernet of WLAN. Typical input voltages are in the range of 120-200 V Dc with peak efficiencies over 96%. These weigh around 15 kg and dimensions are 55.3*41.8*17.5 cm.
Fronuis makes solar inverters with capacity ranging from 1.5kW to 100kW, ensuring that every consumer gets the right capacity inverted. Typically, the ingle phase inverters have an input voltage of 80-1000V, and the output voltage can range between 180-270V at 50-60Hz. With dimensions of the order of 43*65*20cm and weighting around 20kg, these inline inverters are ideal for indoor and outdoor applications, though the warranty is only 2 years with an option of extending to 5 years.
