The story of SMA: a brief company overview

SMA is a true legend in the solar industry and one of the most prominent manufacturers out there. Founded in 1981, it has a rich history that dates back to the earliest days of solar photovoltaics. For a considerable period of time, the manufacturer's string converters, sold under the names Boy and Tripower, were widely recognized as the absolute best in the market.

Starting out as a team from the University of Kassel, the company has blossomed into a formidable force with more than 3,000 employees and generating over $1 billion in revenue in 2022. At present, SMA is a premier producer and manufacturer of solar converters for photovoltaic systems that can be connected to the grid, used for off-grid power supply, and operate as backup power sources. Although they manufacture most of their products in Germany, they also have a plant in China.

Introduction to the SMA Sunny product line

SMA Sunny Boy inverter

The company’s most renowned product, this compact model comes in various sizes ranging from 1.5kW to 6kW. With a maximum efficiency of 97% and advanced visualization capabilities on the manufacturer’s Energy App, it guarantees maximum transparency. The device comes with a 5-year warranty, which can be extended to 10 years for added peace of mind.

When it comes to converters, reliability is key, and for a long time, the Boy series has been widely regarded as the most dependable choice on the market. Moreover, it stands out as one of the most affordable grid-tied options you can purchase.

SMA Sunny Tripower inverter

Tripower is a converter of medium size, which finds application in both residential and commercial settings. Its power capacity spans from 3kW to 10kW, and specific models boast an impressive efficiency of up to 98.4%. Notably, these converters are renowned for their remarkable reliability, which makes them an excellent choice for commercial-scale projects.

The patented 'ShadeFix' feature in the Tripower model provides one of its most significant benefits - ensures that minor shading problems no longer impact your overall energy yield, which is a common issue with other converters. Additionally, the product comes with a standard 5-year warranty and is easily extendable to 10 or even 15 years.

SMA SI system

SMA Sunny Island inverter (SI) is renowned for its dependability in off-grid solar applications, and it stands out as one of the few top-notch off-grid converters that have demonstrated remarkable durability over time. Introduced over a decade ago, the SI series quickly emerged as the go-to choice for off-grid setups, be it single-phase or advanced three-phase installations.

SMA Sunny Island inverter stands out as the sole multi-mode converter with high power that boasts an impressive IP54 weather rating, making it suitable for installation in open and exposed areas. Furthermore, what sets this product apart from other systems is its exceptional scalability, which is unrivaled by most other converters.

SMA Sunny Boy Storage

The company has developed a solution to incorporate battery storage into a grid-connected home through the SBS model. This innovative energy storage system, which is AC-coupled, allows it to connect with widely used high-voltage batteries and can be combined with any standard solar converter. While the SBS is compatible with any converter, its effectiveness is heightened when paired with the manufacturer’s Boy model, as it allows for monitoring of the entire system on a single integrated platform.

Should You Consider Purchasing SMA Products?

In conclusion, SMA has a well-deserved reputation as one of the leading manufacturers of high-quality and reliable solar converters. While the company did face some setbacks in the residential market, it has made significant strides in recent years with innovative monitoring and upgraded products. With positive feedback from solar installers and industry professionals, choosing SMA equipment for your solar power system is a wise investment that ensures efficiency, reliability, and excellent customer service.
