Enphase – Comparing
Solar Inverters

Make the smartest choice in solar

Microinverters or conventional? The choice is yours.

Microinverters, string inverters, and string inverters with DC optimisers?
With all the solar technologies out there and not a lot of straightforward information, deciding on the right solar option can be confusing. We’re here to break down some key differences for you (in a way you won’t need an engineering degree to understand). Once you’ve got it down,
you might find the choice is simpler than you thought.

In an Enphase system, there’s no single point of failure.

Think of solar panels like bulbs in a string of Christmas Tree lights. In conventional inverter systems, when one panel fails, the whole system fails. Or when one panel’s output drops, thanks to fallen leaves, a passing cloud, or some other unavoidable factor, the system’s overall performance drops to match that lowest-performing panel. With microinverters, each panel operates independently so no matter what happens to any one panel, the rest of your system keeps shining bright.

Don’t let the littel things drag you down.

Microinverters

Whether it’s a leaf, dirt, or a cloudy day, obstructions happen all the time, to every system. With microinverters, only the individual panel is affected, while the others keep performing to their fullest. At the end of the day, that means more solar power and greater energy savings from the same panels.

String systems

A string inverter system can only perform as well as its lowest performing panel. So if shade or a pile of leaves hinders one panel’s performance, every other panel operates at the same diminished capacity. That means every little obstacle has a big impact on your energy production and takes a bite out of your potential savings.

When safety counts, the choice is clear.

Enphase

Low-voltage DC never exceeds 60 volts

DC-AC conversion happens on the panel level, so there’s never any high-voltage power traveling through your system. In other words, you don’t have to worry about the dangers lurking on your own roof.

String system

Up to 1,000 volts DC on roof

In a string inverter system, there’s a lot of high-voltage electricity working its way across your roof. That comes with potential hazards to both you and your installers, including arc-faulting and fire.
