How the Microinverter System works

Solar panels may be on top, but it's the inverter that does all the real work. Choosing an inverter technology is the most critical decision you'll make when going solar. Enphase Microinverters offer the most advanced inverter technology on the market, which means higher production, greater reliability, and unmatched intelligence. The solar panels on your roof absorb sunshine in the form of direct current (DC) power. Tucked beneath each panel, a micro inverter converts that DC power to alternating current (AC), the form of electricity your home can use.


The smarter choice in solar technology.

Higher production, best savings

Enphase micro inverters are proven to produce more energy than other technologies.

Microinverters 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. Inverter icon with green check mark to represent reliability
More reliable

Because they function independently, micro inverters are inherently more reliable: there's no single point of failure in a micro inverter system. Plus, we're obsessive about quality, and our products reflect that. If one panel goes down, the others won't go down with it. Enphase microinverters undergo the most rigorous product testing in the industry.

Micro inverters are safer than other inverter technologies. An all-AC system means no high-voltage DC power on your roof. Enphase Microinverters are commonly chosen for schools, since they meet even the strictest government safety requirements.
More cost-effective

In addition to the greater energy savings from higher production, Enphase microinverters are just a better long-term investment. Enphase microinverters come with a 10-year warranty; string inverters need to be replaced at least once in the lifetime of the system. Streamlined components make for quicker and less costly installations. High-quality materials and remote problem-solving save money on repairs. 
A system that fits your needs, now and later.

The Enphase System is flexible, so you can design a system to fit today's budget and energy needs, and expand it later as your needs evolve. Want to add more panels or a solar battery? With microinverters, it's no problem.

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, every system experiences some shading at some point during the day -- and Enphase tolerates shading better than others. Second, shading is only a part of the story. Think dirt, leaves, scratches, snow….
Third, 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.​
