McNae Electrical Solutions installs a lot of microinverters—why is that? The answer lies in three simple words:
Safe, smart and tough
With solar, you’re in control of your electricity costs, and that’s a powerful thing. You can save money. You can manage your own energy. You can be energy independent. But none of that matters if it’s not safe. Enphase microinverters are built from the ground up with safety in mind. They are the only type of inverter that does not bring high voltage DC down into your house.
SAFE—works like the rest of your AC-powered home
Traditional rooftop solar systems generate high-voltage DC that can spark a fire if something goes wrong between your panels and the central string inverter. With a microinverter system, there is no dangerous high-voltage DC running across your roof, only the same standard AC that powers your appliances. View this video to understand how a micro inverter system eliminates any possibility of a roof fire due to high voltage DC arcing.
SMART—a single app for everything
All our microinverter systems come standard with the Enphase Enlighten app (iOS and Android). This gives you a real-time view of your energy production and consumption at the individual solar panel level. So, you can make informed choices about how best to use the energy your home generates.
Powerful performance means lower electricity bills. Did you know that a traditional system with a string inverter is only as strong as its weakest solar panel? This is because the panels are daisy-chained together like Christmas lights. With this setup, you can lose more than half your production if just a small section of panel is covered with shade or debris. With Enphase microinverters, each panel is fitted with its own microinverter to create panel-level independence and generate the most energy possible.
Be ready for tomorrow with unparalleled flexibility. Enphase microinverters allow solar panel arrays to be installed across multiple roof areas and orientations. This level of design agility enables the maximum harvest of sunlight and means that your system expansion options are only limited by your roof space. Compare this to string inverter systems where each inverter can only handle solar panels facing a maximum of two directions.
Tough—own a system you can count on
In Australia, the consumer organisation CHOICE ran a member survey on solar PV systems that had been installed on more than 1000 houses. Only 3% of Enphase microinverter owners reported problems. This is significantly lower than owners of the leading traditional inverter manufacturers where 19% reported problems. See Choice Survey results: Are you happy with your solar panels?
No single point of failure. Unlike traditional inverter systems, where all the power from your panels runs through a single string inverter, if a panel or Enphase microinverter stops working, the rest of your system will continue to function with minimal disruption. Your Enphase Envoy communication gateway will also automatically inform your installer and in many cases, issues can be fixed remotely, saving you days of downtime and the hassle of having to call out an electrician.
Longest warranty on the market. Enphase is obsessive about quality and stands by its products with the industry’s strongest warranties. Enphase microinverters come with a 10-year warranty as standard, with options to extend coverage to 15, 20 or 25 years. Enphase is one of the only inverter manufacturers to offer a warranty of up to 25 years in New Zealand. See Enphase Warranty upgrades
