Enphase Microinverters

Enphase Microinverters

Your Energy Solutions highly recommends Enphase Energy series of microinverters. Enphase microinverters are capable of pairing with solar panels up to 360-watts. Enphase energy has 3 microinverter models available: M215, M250, and the newest model, the S280, which is designed and foward-engineered to work with battery-storage systems.

Each Panel Gets a Microinverter

  • Each solar panel fastens directly to an individual microinverter out of site, on your roof
  • All solar panels connect together in “parallel” instantly converting DC energy to AC energy, operating at 240 volts.
  • Microinverters are great for all residential PV applications and are an excellent value.
  • Enphase microinverters eliminate any single point of failure, guaranteeing your system uptime, reliability, and production. If one microinverter fails, the others continue to produce power without issue.

Industry-Leading 25 Year Warranty

  • All Enphase microinverters carry an unsurpassed, industry-leading, 25-year OEM warranty.

Ideal for All Residential Solar Installations (NOT just where shade exists)

Many inexperienced installers mistake Enphase for being the recommended product for installations where transient shade is present. Though microinverters are the best approach for those installations, they also harvest more power than any other any other type of inverter system in the solar industry.

  • MPPT (Maximum Power-Point Tracking): Enphase microinverters give increased energy production resulting from MPPT harvested at the panel level. Enphase MPTT can can result in as much as 26% more power production compared to any other type of inverter system.
  • Microinverters are also ideal for applications where solar panels receive transient shade from immovable objects such as nearby trees, chimneys, or adjacent structures.
  • Unlike central inverters, if one panel is shaded, only that shaded panel sees a drop in production. It does not affect production of other panels in the system.

Great for Multiple Roof Orientations

  • Microinverters are essential for PV solar systems with panels on multiple roof sections facing different directions. Enphase microinverters eliminate any possibility of “string mis-match”, inherent to regular string inverters.

Panel-Level Monitoring

  • “Enlighten”, the Enphase monitoring platform, enables real-time data and analytic measurements for production of individual solar panels as well as group performance. This platform is accessible from any computer, tablet, or smartphone, and in our opinion, is the best monitoring platform available in the industry.
  • The Enlighten portal allow you to track historical production information for every solar panel individually, down to real-time 5 minute increments. This level of monitoring ensures solar panel warranties can be met by panel manufacturers and enforced by consumers.
  • Panel level monitoring also allows YES, as your installer, to remotely diagnose any potential issues.

Number of Supported Microinverters

The maximum number of microinverters (and solar panels) supported depends on the size of your main panel (in amps).

In the event you need a larger system than your home’s Main Electric Service Panel (MSP) can accommodate, YES proves in-house MSP upgrades. Contact Us to have one of our certified electricians inspect your home’s electrical system and provide you a quote. MSP upgrades are eligible for the 26% federal tax credit when installed in tandem with your new solar electric system.

Max Solar Panel Rating: The maximum solar panel size recommended before it’s more cost effective to go with a higher efficiency microinverter.

Max AC Output: Solar Panels produce electricity in Direct Current (DC) while homes, businesses, and the grid is wired in Alternating Current (AC). The inverter coverts DC to AC. This value is the maximum “useable” electricity that can be produced.

Which Microinverter to Choose? Clipping explained.

It involves balancing cost, ROI & desired number of panels

Example: Suppose you choose LG 300 panels. For this setup, Your Energy Solutions recommends pairing with a M250 microinverter, which will produce a maximum AC power output of 250 watts.

When LG tests these 300-watt panels in their lab, conditions are perfect, tested free of dust, dirt, bird droppings, leaves, and shade. Under these conditions, the LG 300 has a peak production of 300 watts. However, in the”real world”, where these solar panels are exposed to the elements on your roof, the same LG 300 will peak at 273.5 watts DC. When converted to AC power, the LG 300 produces 246.2 watts AC, within the limit of the microinverter. During the summer, this LG 300 watt panel will actually peak and exceed the microinverter’s output capacity and “clip”. This peak will only occur during the summer months and for a small duration of time.

For most customers, the goal for solar is to maximize savings. A S280 will capture all the production during these peak times, but the additional cost of going with a higher-capacity microinverter is much greater than the marginal benefit of slightly extra power.


This is why we recommend the M250 for a LG 300 panel. The M250 will maximize production at 250 watts and not go greater. This is known as clipping. In fact, Enphase allows for a maximum DC input (solar panel size) of 310 watts.


During times when clipping is not happening (such as mornings, evenings, and winter), a higher rated solar panel will always outperform a lower rated. For example, an LG 300 panel will always outperform a Mitsubishi 265.


For buildings with a smaller Main Panel size, it may be advantageous to go with a smaller capacity microinverter to allow for more panels and a larger capacity solar panel to maximize production.

Going Solar with Enphase

Enphase is a highly-recommended way to go solar. Our energy consultants will help size your system, including determining which combination of solar panels and inverters that maximize production, reliability, and savings.
