APsystems Microinverters - APsystems USA | The global leader in multi-platform MLPE technology

The APsystems Microinverter

The APsystems microinverter solution marks a breakthrough in solar technology, making PV arrays more powerful, smart, reliable, cost effective and safe.

Is a premier choice for optimizing your solar energy harvest, simplifying system design and maintenance, and improving safety for both installers and owners.

the APsystems microinverter advantage

smarter & safer

Our microinverter technology individually monitors and maximizes power generation for each module in the array, boosting system efficiency by up to 20 percent. Each APsystems microinverter handles multiple PV modules, lowering logistics, installation and balance-of-system costs.

All APsystems microinverters are engineered to inherently comply with 2014/2017 NEC 690.12 requirements for Rapid Shutdown out of the box, ensuring safety of system installers and emergency responders.

The APsystems Microinverter Advantage

Powerful

Shifting environmental factors constantly challenge the efficiency of solar arrays; dust, debris and shade can drastically lower power output. With a conventional “string” inverter system, the least-performing module determines the productivity of the entire array – so the shadow of a single leaf will compromise the whole system.

APsystems microinverters give you more power, independently optimizing the output from each solar module. If one module is shaded, all the other modules in your array will still operate at full power. Built into each APsystems microinverter is a function called Maximum Power Point Tracking. Working at hundreds of times per second, the APsystems microinverter continually finds the greatest possible module power, greatly increasing overall system performance.

APsystems microinverter installations are typically 5-15 percent more efficient than comparable “string” systems. That’s like having more solar modules on your roof with the same-sized array.

Warranteed

All APsystems products undergo rigorous factory testing, evaluation, and field tracking, guaranteeing you the highest quality, most dependable microinverters for your solar array. APsystems microinverters are designed for the same lifespan as the solar module.

As the industry leader in solar microinverter technology, APsystems will always be here to stand behind our products. APsystems offers a microinverter warranty of 25 years.

Smart

The APsystems microinverter solution combines highly efficient solar harvesting and power conversion with our high-tech data collection and communication program – giving you real-time performance and efficiency about your solar array. The APsystems Energy Communication Unit, or ECU collects module performance data and sends it to an internet database.

The APsystems Energy Monitoring and Analysis, or EMA software allows around-the-clock management of your solar array through any web-enabled device, like your home computer or smartphone.

Reliable

You want an integrated system that works well together. The APsystems solar solution combines highly efficient power inversion with state-of-the-art data collection and monitoring so you’ll know precisely how your system is functioning at all times. No matter where you are.

Safe

Unlike central inverters with high DC voltages in the hundreds of volts, APsystems microinverters tie directly to the low-voltage PV module and connect to the public power grid via standard AC voltages – enhancing worker and homeowner safety, and eliminating the possibility of high-voltage DC “arc” fires.

Our products are engineered for safety – a key feature as state codes change to keep up with the spread of solar across our communities. The Rapid Shutdown functionality required under the new NEC 2014 is built into every APsystems microinverter.

Cost Effective

The APsystems microinverter is the affordable, flexible solution for your solar power array. The compact, independent design allows easy installation on virtually any available surface, and because it is an integrated system, the APsystems microinverter solution simplifies system design. Solar arrays can be easily expanded at any time, hassle-free.

Additionally, the APsystems microinverter solution gives solar installers a competitive advantage and, when fully utilized, enables installers to install faster and generate more profit than competing systems of the same capacity.
