What’s underneath the panels makes all the difference


McNae Electrical Solutions recommends and installs Enphase micro inverters in nearly all installations. The reasons for this are two-fold. First, because of the inherent advantages of micro inverter technology, and second, because of our huge buying power, we can install a micro inverter system at no more cost than a string inverter system.

McNae Electrical Solutions is one of the most experienced installers of Enphase micro Inverters in New Zealand, and we are the largest installer of Enphase Systems in the lower North Island. Our competitive pricing is supported by a dedicated engineering team with over 300 Enphase micro inverter installations completed.

Enphase systems are now right across New Zealand. McNae Electrical Solutions is proud to be playing a major role in the uptake of solar power in the lower North Island. Enphase have recognised McNae Electrical Solutions’ record of superior customer service and quantity of installs and has granted us Preferred Enphase installer status. This ensures that you get the right advice, system design and technical support.

While we recommend Enphase micro inverters, McNae Electrical Solutions also installs string inverters in larger size systems, in off grid, and in hybrid installations.


Micro inverter technology allows each panel in a solar system to work independently from the other panels, ensuring maximum output of clean renewable energy for your household or business. Micro inverters help avoid common roadblocks that stop a solar installation on many houses such as patchy shade and small roof areas. An Enphase micro inverter system uses a small DC to AC inverter under each panel. This means that each panel’s performance does not affect any other panel’s performance – this is of particular use when there are shade issues, or when you need to face panels in two or more directions.

Why Choose Enphase?

The smarter choice in solar technology.

Higher production, best savings
  • Enphase micro inverters are proven to produce more energy than other technologies.
  • Micro inverters operate independently, so each panel performs to its fullest. One shaded or dirty panel won’t affect the rest of the system.
  • Burst technology lets micro inverters produce more at dawn, dusk, and in low-light conditions, for a longer solar day.
  • Higher production, no matter what nature brings. Maybe your roof isn’t shaded, so you think micro inverters aren’t for you. Well, think again. First, shading is only a part of the story. Think dirt, leaves, scratches, snow… Second, even if you keep your panels spotlessly clean, wear and tear won’t happen uniformly, and temperature differences occur naturally. No matter what, you’ll deal with panels operating at different levels of efficiency (an occurrence known as module mismatch). And if you’ve got micro inverters, you’ll maximize your production in spite of it.
