Enphase M210 Inverter Series

The Enphase M210 Micro-inverter shifts DC to AC conversion from a large, centralized inverter to a compact unit attached directly to each solar module in the power system.

Distributing the conversion process to each module makes the entire solar power system more productive, reliable, and smarter than traditional inverter systems.

Enphase micro inverters provide maximum power point tracking (MPPT) at each solar module maximizing energy harvest at all times, even during variable light conditions. Forget about string design, marginal designs, co-planarity, and matching modules. With the Enphase micro inverter system additional modules can be added as needs and budgets grow without requiring the replacement of a large centralized inverter.

Technical Information

For applications outside the temperature range of -25C to +75C, the system designer should verify that the module voltage and/or current will not exceed the microinverter model's nameplate ratings under all expected environmental conditions. The module specification sheet listed under the DATA SHEETS tab of the product description contains all of the necessary module information to make this determination. The ASHRAE Handbook is the recommended source for weather data for a particular location.


Connector Suffix Description
MC4 Locking -S12 MC-4 compatible (S12) connectors: - Positive DC output of the PV module (+) connects to microinverter connector labeled negative (-).
Tyco SolarLok -S13 Tyco (S13) connectors: - Positive DC output of the PV module (+) connects to microinverter connector labeled positive (+).

It is important to verify the correct connector type when purchasing from your distributor.

Choosing your Enphase Micro Inverter

A generally accepted practice is to use a module with an STC power rating of 1.2 times the AC power output rating of the inverter. Many system designers use a multiplier of 1.25 or 1.3. For an M190 this would suggest a module power rating of 228 to 250 watts. However, the appropriate module power rating for a given application depends on the specifics of that installation.
