While solar panels are at the forefront of a PV system, it's the inverter that does all the real work. Solar inverter is a power conditioning unit that converts the DC power generated from the solar panels to AC power. The latter is used for running your appliances like the TV, microwave, refrigerator, etc. So, choosing an inverter technology is the key decision you'll have to make when going solar. Enphase Microinverters are the most advanced inverter technology on the market, which means higher production, greater reliability, and outstanding intelligence.
Solar inverter at the heart of the PV system
Enphase Energy is the world's leading clean energy solution provider, successfully operating since 2006. It pioneered the concept of a microinverter which is now the company’s staple product. Enphase team comprises dedicated people, who are tirelessly looking for better ways to make solar energy simpler, smarter and more affordable.

Quality of Enphase Inverters
Enphase solar inverters comply with the highest quality standards, which has been proven by high scores from the NYSERDA quality assurance inspections.
«Enphase has an outstanding reputation for technology innovation and quality»

Enphase inverters are tested in extreme weather and climate conditions, and perform greatly in tropics or tundra or anywhere in between. What’s more, these units are designed to last over 100 years under such high environmental stress conditions. Enphase has proven to be one of the most reliable inverter manufacturers in the world.
In January 2014, Enphase conducted a heat study during one of Australia’s hottest summers in recorded history. For example, Adelaide (South Australia) set a record for extreme temperatures with 12 days of 40°C (104F) or above, reaching the peak at 45,9°C (115°F). No Enphase Microinverter across Australia shut down due to temperature during that period.
A microinverter is a very small inverter attached to each individual solar panel. But don’t judge the book by its cover! It provides for a better performance of the PV system than a conventional string inverter.
Microinverter vs. String inverter
Imagine a leaf falling on one of four panels and thus hindering its performance until it's blown away. If you have a string inverter, it’ll make the other three panels operate at the same diminished capacity as the first one. With microinverters, only one panel will be affected, while the others will keep performing to their fullest. At the end of the day, that means more solar power and greater energy savings from the same panels.
In a string inverter system, there's a lot of high-voltage electricity (up to 1,000 volts DC) working its way across your roof. This is important because it is often voltage from DC electricity that causes arcing when a cable is damaged, which in turn can lead to heating and a potential fire.
In a micro inverter system, DC-AC conversion happens on the panel level, which means there's no high-voltage power traveling through your system. In other words, you don't have to worry about the dangers lurking on your own roof.
It usually takes no more than 2-3 hours to install Enphase microinverters in comparison to almost 5 hours needed for a string inverter. These are plug-and-play components which speed up the installation process. Moreover, if something goes wrong with your microinverter, you won’t have to call an installer and wait for them to come and investigate the problem in person. Smart monitoring allows the installer to pinpoint the issue instantly from wherever they are, and often resolve it remotely.
How long is the warranty on the Enphase inverters and microinverters?
Enphase micro inverters come with a 25-year warranty, which is much longer than the standard 10 years for most string inverters. If you are a United States resident, please, consult this IQ-Series Microinverter Limited Warranty document for more information, or find the warranty information relevant to your country on this page.
What is the price of Enphase inverters?
While the price of Enphase solar inverters might be slightly higher compared to string inverter systems, they’ll definitely pay off quickly. The price range is widely depending on the microinverter model and operational characteristics. Check current prices on Enphase microinverters here.
