No matter your residential power supply requirements, it’s fair to say that there is an SMA inverter option to suit. That being said, is the SMA solar inverter range likely to meet end-user expectation?

An entirely different question facing all solar inverter manufacturers as energy storage becomes an essential desire for those looking to maintain a self-generated power supply.

What we do know is that when the likes of SMA make a move, the industry stops for a moment and pays very close attention.


A bold statement in what would soon be the modern trend. One of he first inverters to embrace the new wave of multifunctional LED interfaces mitigating a common point of failure in conventional inverter designs. SMA proves itself as an industry pioneer once more with the next generation SMA Sunny Boy range.

As data becomes more powerful than ever, SMA falls short in offering a single-phase energy meter to accompany the SMA Sunny Boy range determining the 3-phase unit is fit for the same purpose. An inhibiting factor where limited switchboard real estate is available.

Severely high performance in testing conditions ensures the SMA Sunny Boy inverter range is an elite solar inverter option for diverse applications.

One of the more refined 3-phase string inverter offerings ever produced raises the benchmark of residential 3-phase consumer expectation. Following an almost identical design to its single-phase counterpart, the SMA Sunny Tripower redefines 3-phase expectation with a modern low noise, lightweight presence.

All-round superior specifications in a compact design makes the SMA Sunny Tripower as a force to be reckoned with on the 3-phase landscape. Similar to the SMA Sunny Boy range, end-users may be slightly dismayed with the absence of a DC-coupled hybrid solar and battery variant in the mix.

Slightly underwhelming in its smaller format, the SMA Sunny Boy Storage range redeems itself with for more significant battery supply requirements.

Single battery supplies rarely meet the expectations of the end-user. Therefore, ensuring a battery inverter with expansion capabilities can facilitate the option of expanded energy storage a reduced cost.

The next generation of SMA Solar inverters provides one of the most comprehensive inverter suites available for the modern home.

However, with such inverter manufacturing prowess, SMA still appears to be holding out on a DC-coupled hybrid solar and battery inverter. While on the wish list for many installers is a dedicated single-phase energy meter to unlock the full insight of the new ennexOS monitoring software in a more accommodating package.

Not without its selected drawbacks, the SMA solar inverter range remains a robust, high-performance electrical inversion machine built to endure a diverse international landscape.

  1. I have spent more then 20 lakh for my house in kerala with Sma invertor 3 phase and its totally useless the reason is in my place in kerala the common electricity supplier KSEB switches off the supply at least 15 to 20 times a day for various reasons and every time it switches off our supply get disconnected even we have the best quality hybrid solar SMA invertor.
