There are many things to consider when selecting a solar module to pair with an Enphase Microinverter. Use the resources on this page to help ensure your selection delivers efficient and reliable performance.
The rating systems and operating behaviors of solar modules and microinverters are very different, and as a result, can cause much confusion about how to integrate the two products. Simply matching nameplate power ratings may seem logical, but it could actually lead to underperformance, or worse, a solar system that simply doesn’t work. The information and resources on this page help clarify the other considerations.
Frequently Asked Questions
What racking products work with Enphase?
Enphase designs its microinverters to easily attach to most mounting systems using standard parts and tools.
For a list of products that have been tested for compatibility, refer to the Racking Compatibility List. This document also provides guidelines for how to check compatibility and quick tips for adapting the microinverter to fit with non-compatible mounting solutions. Racking Compatibility List »
Is my solar module compatible with Enphase?
Enphase Microinverters support a wide range of solar modules, including both mono- and poly-crystalline product types.
Compatibility primarily depends on the electrical properties that the module will produce in the field. These properties must match the input range of the microinverter.
To determine electrical compatibility, refer to the Module Compatibility Calculator. Module Compatibility Calculator »
What size solar modules work with the M215?
It is best to use a solar module with a higher power rating than the microinverter’s because the solar module’s output is highly variable and degrades over time. For example, the M215 Microinverter is well-suited for solar modules with power ratings beyond 270W (STC).

Bigger is Better: Sizing Solar Modules for Microinverters
Enphase recently completed an in-depth analysis of the impact of using high-power solar modules with the M215 Microinverter.
The analysis confirmed that:
- Solar modules up to 260 Watts are well-suited for the M215 Microinverter.
- Pairing high-power solar modules with the M215 reduces the system’s installed cost and increases return on investment.
These findings highlight the need to evaluate solar modules based on their expected field performance, rather than their nameplate rating.

Also called “right-sizing,” achieving the correct size ratio between a module and microinverter is an essential consideration for solar integrators and end customers.
This study explains the performance and economic implications of different sizing ratios.
