Note: For Both 60 and 72 Cell modules Enphase Energy, the world’s leader in solar microinverter technology, used Intersolar North America 2013 as a platform to launch their latest generation microinverter:  Enphase M250. The company’s first generation microinverter, the Enphase M175 is considered to be the world’s first commercially successful microinverter. The M175 was followed by the Enphase M190 microinverter, which had built-in trunk cables and was compatibility with both 60 and 72-cell solar modules. Unlike the first two generations, the Enphase M215 microinverter featured a single mounting bracket and an improved cabling system, allowing up to 17 microinverters per branch circuit instead of 15 with the Enphase M190. The Enphase M215 is a lightweight microinverter designed for 60-cell solar modules. Enphase M215 has a maximum output of 215W AC – with a 96.5% CEC efficiency rating. It also features a single-bolt bracket for dramatically simplified installation, which has been passed on to the 4th Generation Enphase microinverter, the M250.

 What’s different about the Enphase M250?

Though the design of the Enphase M250 looks almost identical to the Enphase M215, the Enphase M250 microinverter is rated at 250W AC, meaning it’s compatible with solar panels up to 300W. But the key improvement to this model is that the M250 DC circuit already meets grounding requirements (NEC 690.35) because it’s isolated and insulated from the ground. This improvement means that when you’re installing an Enphase M250s, you won’t need additional Grounding Electrode Conductor (GEC) in between each microinverter (copper). This not only simplifies installation but enhances safety and saves material and labor costs. The Enphase M250 microinverter comes with the industry-standard 25-year warranty. Like the M215, the Enphase M250 is rated at 96.5% CEC efficiency- the highest efficiency for microinverters available. Similarly, it’s also NEMA 6 rated for severe temperatures and humidity. When using Enphase microinverters (and an Envoy communications gateway), you can monitor the production of your system remotely with a web-based software called Enlighten. The newest Envoy can handle up to 500 microinverters – or 100kW. Enphase now offers Enlighten in two versions of the software: one for solar professionals to maintain the systems they’ve installed, and one for system owners to monitor the output of their system.
