3 Ways Enphase M215 Just Got Better

Enphase Energy just revealed some key improvements to the Enphase M215, 215 Watt microinverter and their system as a whole.

Take a look at the new features…

1. Enphase M215 with Integrated Ground

Photovoltaic (PV) systems in North America have normally required bonding each microinverter together with continuous copper grounding wire.  The purpose of this standard is to prevent fires, protect workers from shocks, and comply with National Electrical Code (NEC).  Some changes to NEC have allowed Enphase to incorporate integrated (DC isolated) ground technology into their 4th generation line, which now includes the M215.

Because the DC circuit is isolated and insulated from the ground, you can now safely install Enphase M215 microinverters without a Grounding Electrode Conductor (GEC) connected to each microinverter.

Coming soon… the 4th generation M215.

Yes, this product meets U.S. National Electrical Code (NEC) requirements Ungrounded Photovoltaic (PV) Power Systems and it’s actually a safer product.

Integrated Ground(IG) technology simplifies this cumbersome installation process, reducing materials and labor costs.  Installers and D.I.Y. customers already prefer to use Enphase for residential systems because of its straightforward installation.  The new M215 further simplifies the process because there’s no need to run copper wire between each microinverter.

Sound familiar?  Last year, Enphase released their fourth generation model, the Enphase M250, which also features this new IG technology.  The Enphase M520, however, is optimized for solar panels all the way up to 300 Watts.

The Enphase M215 is compatible with modules up to 270W, a lower wattage range where consumers are finding the best dollar per Watt on solar panels.  So basically, Enphase put all the benefits of the M250 into the M215.

Oh yeah, the new Enphase M215 also has a CEC efficiency rating of 96.5% compared with the previous version’s 96%.

2.  Wi-Fi option for the Envoy Communications Gateway

Now Available!

newsroom-feature-envoy-wifi-launch1The Envoy Communications Gateway is the hub connects your Enphase microinverter system to Enlighten, Enphase’s web-based monitoring software for PV systems.

Instead of running an Ethernet cable from the Envoy hardware into a broadband router, you can now connect the Envoy Communications Gateway with the new wi-fi option (pictured top right).

The new Wi-fi option simplifies connectivity and makes finding a location for the Envoy way easier.

Connect up to 600 microinverters to one Envoy.


3. MyEnlighten & Enlighten Manager Software

Customers who use the Enphase Envoy to monitor their systems get a lifetime subscription to Enlighten, Enphase’s web-based monitoring software.  There two main parts of the Enlighten software, each with their respective purpose.  Enlighten Manager is for solar professionals and MyEnlighten is designed for system owners.

Through Enlighten Manager, solar professionals monitor the performance of PV systems they’ve installed and potentially troubleshoot issues remotely.

MyEnlighten is an intuitive web-based software for mobile devices and desktops that helps people better understand how their PV systems are working for them.   Homeowners can use MyEnlighten (pictured below) to easily track the performance of their PV systems over time.



It seems like Enphase has been listening to their customers.  For those who are designing PV systems with microinverters, are you using the M215, the M250, or an older model like the M190 (w/ built in trunk)?
