Each inverter manufacturing company is racing to the top in this list by keeping on bringing in innovative and more cost effective solutions for it’s customers to opt for. We have prepared this list according to how the company provides with the products along with the service rating and easiness of use.
Inverters are an important part of any solar pv installation, they are the heart of the solar plant. Although the inverters main job is to convert the DC power produced by the solar panels into usable AC power, it has many auxiliary purposes also. To list a few:
- Inverters enable monitoring so installers and owners can see how a system is performing.
- Getting the maximum power out of the plant by using MPPT technology
- Charge Batteries and maintain their health in case of Hybrid / Off-grid inverters
- Protect the grid with anti-islanding and the panels from high voltage or current surges
When choosing any solar inverter for your solar pv plant, the following important factors must be considered:
Efficiency of the Inverter
Warranty period and serviceability
Online Monitoring feature capability
As a general reference, the cost of the inverter can range between Rs6-Rs14 per watt of your solar plant. A golden rule to keep in mind is not to opt for the most expensive but also not the cheapest inverter when trying to install your plant economically. You want the inverter to function properly and also the company to provide with service in case of any warranty claims.
Please note that this list is not in any chronological order according to ratings, we are listing the top solar inverter manufacturers in India. You can find the links to each manufacturer website in case you wish to learn more in the bottom of this page.
Established in 2006, SolarEdge developed the DC optimized inverter solution that changed the way power is harvested and managed in photovoltaic (PV) systems. The SolarEdge intelligent inverter solution maximises power generation while lowering the cost of energy produced by the PV system, for low return on investment using individual devices connected to each panel. It eliminates the need of using micro inverters on each panels and optimises the output on a per panel level. This is a one of it’s kind revolutionary technology available which has serious benefits to the energy production capacity of your Solar PV Plant.
They also have solutions to charge your Electric Vehicle using solar power in case you plan to buy one. The warranty timeline provided by Solar Edge is one of the highest in the industry.
Nearly all reputed solar inverter manufacturers provide with an energy monitoring service but Solar Edge takes the crown in this !
Fronius International GmbH is an Austrian photovoltaic manufacturer based in Pettenbach, Upper Austria. Fronius is active in the fields of welding technology, photovoltaics and battery charging technology. Fronius inverters are efficient and reliable and form the indispensable heart of every photovoltaic system. Power categories ranging from 1.5 to 27.0 kW guarantee suitability for virtually any system size – from a family home to a large-scale system.
Fronius inverters are concentrated on a comparatively smaller sized plants upto 27kW being the maximum size till date. But they are one of the best manufacturers in this.
SMA Solar Technology AG (meaning System, Mess and Anlagentechnik) is a German solar energy equipment supplier founded in 1981 and headquartered in Niestetal, Northern Hesse, Germany. SMA is a producer and manufacturer of solar inverters for photovoltaics system with grid connection, off-grid power supply and backup (hybrid) operations. SMA sells photovoltaic solar inverters as product families using the Sunny Boy name for home systems, Sunny Tripower and Sunny Highpower for medium-sized plants through the multi-megawatt range and Sunny Central for ground-mounted systems and solar farms, often from 500 kW to the several-megawatt range for self-consumption of solar power and feeding into the utility grid. SMA also produces the Sunny Island for independent, stand-alone systems as well as off-grid and on-grid battery systems, the Sunny Boy Storage and the Sunny Central Storage for grid-tied battery systems of all sizes.
Earlier inverters used to have transformers inside, causing them to be heavy and low in efficiency. Come 1999, KACO new energy revolutionised the market with the first series-ready string inverter without transformer. To this day, their string inverters are manufactured in Germany, but have long since captured worldwide markets. They are equipped for a wide variety of applications in PV plants of all sizes - from single-family homes to decentralised multi-megawatt solar parks.
KACO is a very common and very good brand to opt for if installing a high capacity solar plant on a commercial or industry establishment. It also has a very high over loading capacity.
Since its establishment in 1997, the company has always focused on the field of new energy power generation, adhered to the market demand-oriented and technological innovation as the power source of enterprise development, and cultivated a professional R&D team with rich R&D experience and strong independent innovation ability. It has undertaken more than 20 major national science and technology projects, presided over the drafting of a number of national standards, and is one of the few enterprises in the industry that master a number of independent core technologies.
