White paper: APsystems improves compatibility with Victron storage solution

Screen Shot 2018-03-15 at 10.44.09 AMWhile APsystems microinverters remain compatible with a wide variety of storage solutions, our engineers took a look at a few microinverter firmware features which could enhance compatibility with storage solution components like Victron’s battery charger. Through a power output frequency shift, the charge controller is able to gradually ratchet the amount of solar energy provided to the batteries up or down, as opposed to a simple on/off operation, resulting in a smoother charging process and improved battery life.

APsystems YC600 smart-grid microinverter NOW SHIPPING in USA

The world’s most advanced solar microinverter, the smart-grid compliant YC600 from APsystems, is now shipping in the U.S. market.

A true utility-interactive microinverter with Reactive Power Control (RPC) technology, the YC600 meets CA Rule 21 requirements and is NEC 2014/2017 Rapid Shutdown compliant. The YC600 sets a bold new standard for solar microinverter technology, boasting an unprecedented 300VA peak output per channel and accommodating 60- and 72-cell PV modules.

A wider MPPT voltage range than competing brands means greater energy harvest for homeowners, and the unit is shelled in a rugged, NEMA 6/IP67, powder-coated aluminum enclosure, bucking today’s trend of plastic casings.

The YC600 builds on the successful APsystems line of multi-module microinverters, simplifying installation while reducing installation costs and time on the job site.

APsystems expands EMA system monitoring & alert capabilities

New features provide comprehensive visibility and enhanced remote troubleshooting

APsystems proudly announces new system monitoring alert capabilities within its online EMA portal. The new alerts will improve communication regarding any production and communication issues with an enhanced email alert protocol, giving installers and homeowners further insight into any potential issues affecting their systems.

While the APsystems EMA has always provided system production reports and alerts, the new alerts will be more targeted, more frequent and more informative.


  1. System alerts will notify an installer if one of their installed systems has an inverter that ceases producing energy.
  2. Registration alerts are issued in the case of inaccurate or incomplete system registration.
  3. Communication interrupt alerts will notify installers in cases where their ECU gateway ceases communicating properly with the EMA online monitoring system which could indicate an interruption of communication between inverters, ECU and/or EMA; or simply a local internet, ISP or router issue.
  4. Production alerts will notify installers of unusually low power production at the individual inverter level, giving them an opportunity to check status online and verify proper operation.

These alerts offer installers a more refined tool for notification and troubleshooting of potential system issues. As with any apparent issue, APsystems always recommends contacting our technical support team if you suspect a problem. Most issues can be reviewed and resolved online and without a truck roll.

Changes made to the EMA are seamless and will be automatically available to all new registered systems and over 31,000 existing APsystems installations worldwide.

Cleaveland-Price, Canada’s Got Solar? earn APsystems Project of the Year Awards


Congratulations to Cleaveland-Price of Trafford, Penn., and Got Solar? of British Columbia, Canada, winners of APsystems Project of the Year Awards.

Cleaveland-Price is honored in the Commercial category for the massive 673kW rooftop array powering the company’s high-voltage switch factory. The project uses APsystems YC1000 true 3-phase microinverters to handle the 2,245-module array, the company’s first-ever venture into solar installation.

Got Solar? is honored in the Residential category for the Lowen family’s Coldstream Corner Farms net-zero project. The 29kW array atop the Helmi and Kornelius Lowen residence in Okanagan, B.C., earned distinction as Canada’s first 100-percent solar organic family farm.

“Microinverter technology is the smart choice for projects of every scale, as these two outstanding winners demonstrate,” said Jason Higginson, senior director of marketing for APsystems. “While their installations are much different in size and capacity, they help the customers achieve the same goal of energy independence. Cleaveland-Price and Got Solar? set a great example for all commercial and residential installers looking for power, reliability and value from their rooftop microinverter arrays.”

APsystems thanks all installers and customers who participated in the 2017 Project of the Year Awards contest. Special mentions were also awarded to Vision Energy of Canada for the Moose Jaw all-electric solar home project in the Residential category, and Sycamore Energy for the Optimist Holsteins 177kW Commercial installation.

Lowen home and organic family farm, Coldstream, British Columbia


Helmi and Kornelius Lowen of Coldstream, British Columbia, wanted to eliminate their power bill – or better yet, start getting a check from the power company under the local net-metering program. Working with a leading Canadian installer Got Solar?, they were able to populate three slopes of their farmhouse roof with solar panels powered by APsystems microinverters.



The output from the solar array should come very close to achieving “net-zero” and maybe even “net-positive,” creating more power than the Lowen home and farm consume in a year. The grid-tied array was so ambitious, local power provider BC Hydro came out and upgraded the transformer and replaced the pole – at no charge to the Lowens.


Add it up, and the Lowens earn distinction as Canada’s first 100-percent solar organic farm.

“What makes this project so special, is that even before we installed the solar system, the Lowens in essence already used solar power to create the majority of their profits,” said Chris Palmer of Got Solar? “The fruits, vegetables and other produce grown by this organic farm are all powered by the sun.”

The 3.7-acre family farm in Canada’s rich Okanagan valley raises tomatoes, onions, cucumbers, strawberries, spinach, lettuce, potatoes, beans, peas, beats, corn, squash, zucchini, and in one recent year, some 27,000 heads of garlic.


“Just about anything you need in a kitchen, it’s right here,” Helmi Lowen told Okanagan Seniors in a video feature. “I get bored very quickly and so does Kornelius, so we enjoy doing the gardening.”

Perhaps more impressive: the Lowens, now in their late 70s and mid-80s, respectively, still work the farm largely on their own.

By helping the Lowens create enough power for both home and farm, Got Solar? and APsystems microinverters helped the couple complete the last link in their quest for self-sustainability. And they still plan to upgrade to an electric car.

Launched in 2015, Got Solar? provides grid-tied and off-grid solar energy systems in Kelowna, B.C., and surrounding areas for residential and commercial clients. They are also the only solar company in the Okanagan that caters to DIY installers.

For the Coldstream Corner project, Got Solar? selected APsystems YC500 dual-module microinverters to support 93, 315-watt modules by Canadian Solar, all but two being 72-cell units. Two 60-cell modules were required due to space constraints around a chimney.

Palmer cited the flexibility of APsystems microinverters that allowed system designers to handle the different module sizes seamlessly. That promises forward-compatibility through the life of the array, he said.


“Should a solar module ever be damaged or fail in the next 30 years, APsystems has essentially ‘future proofed’ their product by making it so widely compatible through its wide-ranging input capabilities,” Palmer says. “No longer do you have to try and find vintage matching panels, rather, you replace with whatever is currently in use and in inventory.

“Thank you, APsystems, for allowing our crews to have shorter installation times, higher productivity, and ease-of-installation that has no equal.”

Like APsystems microinverters, the Lowens are proud examples of industry and productivity over the long haul.

“A lot of seniors come here and say, ‘I couldn’t do what you’re doing,’ and I don’t believe that,” Helmi Lowen told Okanagan Seniors. “A lot of people could do it. They don’t have to do it, but they could do it. They say no to big gardens, but they could start small in their own backyard or even in their apartment. There’s always a plot there for seniors to go and get their hands dirty.

“If you say you can’t, you can’t. But if you say you can, you can.”
