Grid Tied Inverters / Enphase M-250 Microinverter

Retail Price: $165.00
Our Price: $149.00
Item added to order

The M250 microinverter is compatible with most 60-cell PV modules (up to 300 W) and works with 208 VAC three-phase or 240 VAC single-phase services. The maximum number of M250 microinverters in an AC branch circuit is 16 for 240 VAC single-phase systems and 24 for 208 VDC three-phase systems. Each AC branch circuit must be protected with a 20 A circuit breaker.

Enphase microinverters have automatic voltage sensing, but the Engage trunk cable used to complete the circuit is specific to the output voltage required. Be sure to verify that the voltage and current specifications of your PV module are within the input range of the microinverter you plan to use. A list of electrically-compatible PV modules can be found on the website. To ensure mechanical compatibility, be sure to order the microinverter with the correct connector type for the PV module that you are using.

M215 models ending in -IG and all M250 models feature an integrated equiment ground through the Engage cable system so seperate grounding of the microinverter case is not required. All M215 and M250 Microinverters are covered by a 25-year limited warranty.
