Global solar technology leader APS rebrands as APsystems


SEATTLE – APS, a global leader in solar technology, is now APsystems.

The brand refinement highlights the company’s commitment to powerful alternative energy solutions, and its evolution from a product-oriented portfolio to a whole-systems innovator.

The phrase “Altenergy Power,” a nod to the company’s original legal name, will appear beneath APsystems in the company’s new mark.

“We’ve been asked at times what ‘APS’ stood for, and it was a trade name we fell into largely for simplicity,” said Kelly Samson, APsystems CEO, U.S. operations. “As our company has become prominent in the marketplace, and our range of offerings expands, we want to make our commitment to alternative energy and advanced power systems more explicit. APsystems is who we are and what we’re about.”


The new positioning follows the company’s strong growth and industry recognition in the U.S. and international solar markets over the past two years.

APsystems is headquartered in Seattle, USA, and Jiaxing, China, with regional offices in Europe and Australia.

The company was founded in Silicon Valley in 2009 with a single product offering, a first-generation microinverter.

An ongoing commitment to research and development, engineering and technology innovation has created a robust module-level power electronics (MLPE) solutions portfolio. The company’s technology is also featured in integrated PV solutions by other solar industry leaders.

More than half of the APsystems workforce is involved in R&D engineering, underscoring the focus on constant product advancement and innovation.

The company’s flagship product, the YC500 microinverter, broke ground among MLPE offerings as the most powerful unit to handle two solar modules simultaneously, simplifying PV system design and significantly lowering installation costs on a per-watt basis.

More recently, the YC1000 microinverter entered the solar market as an innovative, purpose-designed unit for commercial applications. The fourth-generation technology offers true 3-phase (balanced AC) output and handles up to four modules per unit, bringing microinverter technology to the untapped commercial segment for the first time.

The microinverters have been successfully deployed on five continents.

“We’ve been very successful providing an alternative to conventional ‘string’ power inversion, moving the market toward microinverters as the standard for residential and small-scale commercial solar applications,” said Andrew Lonseth, APsystems president, U.S. operations. “As we expand our systems portfolio, we will continue to bring new and innovative technology offerings to the alternative energy market.”

APsystems products are designed around a flexible and powerful Field Programmable Gate Array (FPGA) integrated circuit, giving the company a significant competitive advantage in design, manufacturing, reliability and cost effectiveness.

The company’s microinverter line is programmable to any grid standard anywhere in the world, and is backed by industry-leading warranties and support.

See for information on the company’s worldwide operations, or for the North American market.


APsystems is a worldwide leader in the development, manufacturing and marketing of alternative energy solutions based on its own proven, leading-edge technology. APsystems is headquartered in Seattle, USA, and Jiaxing, China, with regional offices in Europe and Australia.

A letter to our solar partners: APS becomes APsystems

It’s been just six years since APS was a Silicon Valley startup – and how far we’ve come in that short time. Founded with the goal of bringing the most advanced microinverter technology to the solar PV market, we’ve passed one milestone after another en route to ranking no. 2 in global market share among top microinverter suppliers by shipments in 2013 (source: GTM Research). Last year was even stronger still.

And we’re not slowing down – demand for our microinverter line is growing month over month in all markets. As we look toward even greater achievements on the horizon, we’re pausing just long enough to reflect on who we are and what we’re about.

With that reflection comes a refinement of our brand: APS will become APsystems.

The new trade name highlights our commitment to powerful alternative energy solutions, and our evolution from a product-oriented portfolio to a whole-systems innovator. The phrase “Altenergy Power,” a nod to the company’s original legal name, will appear beneath APsystems in our new mark.

The new name will launch August 31st. With the brand refinement, we’re also launching a new website,, an online nexus for our worldwide operations with links to offices in each regional market. We hope you’ll visit the site and see the APsystems big picture.

What’s next? Big things. We’re making a strong push into new markets worldwide, and rolling out even more powerful solutions to accommodate new and emerging technologies. Expect more announcements throughout the coming year.

Our name has changed, but our values are the same. We remain passionate about solar power and advancing our clean, renewable energy future. We offer maximum value to customers through excellence of products, pricing and support. Honesty, professionalism and teamwork define our company. Add them up, and we believe an informed customer will always choose APsystems.

We’re excited about this moment, and we want to share the news with our valued solar partners like you. We look forward to a bright future together.


Kindest regards,

Andrew Lonseth
President, U.S. Operations
