SMA founder Günther Cramer, 62, dies

Günther Cramer, SMA Solar Technology AG’s founder and longstanding CEO of the solar inverter manufacturers company, has died aged 62 after battling a long and difficult illness.

The company released a press statement this morning paying homage to Cramer’s work and positive influence on the clean energy landscape.

Current SMA CEO Pierre-Pascal Urbon spoke of Cramer’s “courage, passion and commitment to energy transition”, while cdw Stiftungsverbund managing director Volker Wasgindt called Cramer an “exceptional person” who would “always have a lasting place in our hearts”.


Günther Cramer was an early pioneer in the world of decentralized, renewable energy and foresaw great potential in the sector long before many of his peers. Alongside his trusted partners Peter Drews and Reiner Wettlaufer, Cramer transformed SMA from a small engineering firm to a globally-admired technology leader.

Cramer’s work has been pivotal in setting the world on the path towards a 100% decentralized and renewable energy supply. His efforts were recognized by a number of leading institutions, earning him the German Environmental Award and the fulsome respect of his peers.

Even after leaving the SMA managing board, Cramer continued to pour his passion into renewable energy initiatives, founding the Günther Cramer Foundation – which is part of the cdw Stiftungsverbund GmbH foundation network – and working on the electrification of remote regions worldwide with the aid of renewable energies.

More widely, Cramer’s work helped set in motion the transition of energy architectures from centralized, large-scale and conventional power plants to more adaptable, decentralized and clean renewable power generation units. Cramer’s motto: “Let’s be realists and attempt the impossible”, continues to shape the vision and perseverence of all SMA and cdw Stiftungsverbund offices.

“In Günther Cramer, we have lost an extraordinary person whom we will never forget,” said SMA’s Urbon. “As the company founder, CEO and Chairman of the Supervisory Board, he shaped the history of SMA and its employees throughout his entire life. His courage, passion and commitment to the energy transition will always continue to serve as a model and an inspiration to us.”

Advanced Energy considers PV inverter sell-off

Power control manufacturer Advanced Energy (AE) is considering the future of its PV inverter business with a sell-off not ruled out.

The company confirmed that it is looking at a number of options for the unit including licensing, partnerships and a sale.

“As part of our annual strategic planning process, we reviewed our entire business to determine the best portfolio mix to achieve our strategic objectives and build shareholder value,” said Yuval Wasserman, president and CEO. “We concluded that the Solar Inverter business as currently configured required a review of our strategic alternatives to capitalize on its strong product portfolio and customer relationships,” he added.

PV inverter sell-off

The company said in a statement that it would make no further comment on the unit until a decision had been taken. It also stressed that there was no guarantee that a sale was imminent.

AE has been losing market share recently, according to IHS data, as a number of Asian manufacturers have muscled out European and American competitors.

AE has recently come under pressure from financial analysts to consider exiting the PV inverter market as it has struggled to increase sales, despite the introduction of a new central inverter and the acquisition of string inverter firm, REFUsol in 2013.

The company had also undertaken a major restructuring and relocation of inverter production to China to reduce manufacturing costs and become more competitive in the market.

Part of the problem has been that AE’s solar PV inverter sales have declined 19.4% sequentially to US$52 million in the last quarter, this despite a booming US PV market.

Management had noted in its last earnings conference call that its sales decline was due to customers delaying PV power plant projects, due to the US anti-dumping case.

However, it was somewhat of a baptism of fire for the new CEO in the last earnings call as financial analysts fired a salvo of tough questions over its continued poor performance in the PV sector, repeatedly asking in one way or another if it was better to exit the PV inverter market.

Why Chinese Solar Inverters more cheaper

Intense pressure in the solar market,inverter companies are also facing a looming shakeout as they deal with continued shifts in global demand and strong downward pricing trends.

Every bit of solar power produced by your panels will pass through your inverter, and it also contains critical safety shutdown electronics (called Anti Islanding Protection). So it is critical that you choose one that is up to the job.

You don’t know one brand of inverter from another. So the simplest, quickest way I can think of to describe how each inverter brand stacks up is to compare them to cars. Because I reckon most of you will know the difference between a Mercedes, a Holden and a Hyundai.

Chinese Solar Inverters
Why Why Chinese Solar Inverters more cheaper?

1. Containment. Central inverters in America are usually located outdoors. But central inverters in China are often housed in containers next to ground-mounted systems. As a result, Chinese products have substantially lower costs associated with weather, cleaning and cooling.

“Indoor-rated models will be cheaper than outdoor models in the U.S., but there can be concerns with finding a space inside a building. In the case of a large ground mount, developers must weigh the cost or trouble of building sheds against paying a couple of cents extra for an outdoor-rated inverter,” said Shiao.

2. Supply chain. Unsurprisingly, the cost of procuring materials and components in China is much lower than in America. But this doesn’t mean that Chinese producers are necessarily using lower-quality products, said Shiao. Leading Chinese companies are also utilizing some of the same suppliers as European manufacturers for major components like power modules.

However, the difference in procurement costs is bringing leading inverter companies to Asia. “This is the reason why you see firms like Advanced Energy and Schneider Electric manufacturing sub-assemblies out of China and India respectively. It’s also one of the key reasons SMA decided to invest in Zeversolar earlier this year,” said Shiao.

3. Testing. More stringent testing requirements also add utility-integration and labor costs for U.S. companies. China’s testing standards are much less strict than America’s — a factor that keeps costs lower, but can also make things more difficult for developers if quality suffers. Solar panel manufacturers are finding that out the hard way today.
