Imagine trying to assemble a puzzle where every piece snaps into place perfectly – that’s essentially what ClickFit EVO technology achieves in roofing installations. This revolutionary system combines EPDM rubber and Bitumen through Esdec’s engineering prowess, creating what industry insiders now call "the Lego of waterproofing membranes."
At its core, this innovation leverages:
While 78% of installations occur on commercial roofs (2024 NREL data), creative engineers are deploying these membranes in:
Esdec’s secret sauce lies in their modified EPDM formulation. Traditional EPDM shrinks about 2% over a decade – their version? A mere 0.3% contraction according to accelerated aging tests. The Bitumen infusion acts like molecular Velcro, creating what material scientists describe as "viscoelastic memory."
Remember when installing roofing membranes required a small army and good weather? The ClickFit system has slashed installation times by 60% in field trials. One contractor joked, "It’s so fast, we have to slow down crews to meet minimum billing hours!"
Comparative studies show:
Esdec’s hybrid solution laughs in the face of -40°C winters and 120°C rooftop summers (don’t try that at home).
While Bitumen comes from petroleum, Esdec’s closed-loop recycling program recovers 92% of membrane waste. Their latest plant runs on solar-thermal energy – ironic for a Bitumen processor? Maybe. Impressive? Absolutely.
Initial costs run 15-20% higher than conventional systems. But when you factor in:
The lifecycle economics tilt dramatically in favor of ClickFit EVO systems.
Esdec’s R&D pipeline includes:
One prototype even harvests rainwater while maintaining a perfect seal – take that, Noah’s Ark!

Sonnen is a German company founded in 2010 that’s been making home battery systemsfor over 11 years. They supplied the first modern home battery systems for on-grid use rather than off-grid. They were originall. . The sonnen Evo is imported from Germany. Sonnen won’t assemble it in Adelaide despite all the support they received from the South Australian government to set up a factory here. A. . At the launch, they didn’t say where the sonnenBatterie Evo’s battery modules are manufactured. But unless they’ve changed their ways, sonnen will source them from two high-quality. . Currently, there’s no datasheet available for the sonnen Evo. Update December 7th 2021: The datasheet is available here. But sonnen presented slides with technical information at th. . The battery has a total (or nominal) capacity of 11 kilowatt-hours. But to protect it from capacity loss, its maximum depth-of-discharge is around 91%. This makes its usable storage c. [pdf]
The sonnenBatterie Evo is a fully integrated AC coupled solar battery storage system designed for outdoor and indoor installations. The sonnenBatterie Evo is an innovative, fully integrated AC coupled home solar battery storage system that has an IP56 outdoor rating and complies with the AS/NZS 5139 standard for outdoor or indoor installations.
But as Sonnen has always positioned itself as a premium brand, it’s not likely to be cheap. Update December 7th 2021: Sonnen has told me they expect the sonnen Evo to cost around $14,000 including installation, which is a much better price than I expected. The sonnen Evo has the following features: 10 kilowatt-hours of usable storage.
The sonnen Evo is imported from Germany. Sonnen won’t assemble it in Adelaide despite all the support they received from the South Australian government to set up a factory here. At the battery launch, sonnen said they would keep that capacity for “future use”.
But it will only be able to charge the battery in a blackout using solar power if the solar inverter is 6 kilowatts or less on the same phase as the sonnen Evo. The battery has a black start capability that you can use during a blackout (if you have 6 kilowatts or less of solar inverter capacity on the backup phase).
The Sonnen EVO matches the Tesla Powerwall 2, serving as an AC battery with an integrated power inverter. Its robust power rating and usability make it an ideal choice for homes with pre-existing solar systems seeking backup power. It is a fully-coupled AC battery that requires an additional solar inverter to function with a solar array.
The sonnenBatterie Evo is AC coupled. This means it operates independently from the solar system, so it doesn’t matter what type of inverter your solar power system has. It can also be installed in homes without rooftop solar panels. This is the sonnen Evo’s power unit, which includes the battery inverter.
