[RE-wrenches] Enphase compatibility heads up

[Brian Teitelbaum]

William,

As long as it's a "standard" 60-cell module, and it likely is (it doesn't show up on a Google search though), it will work fine with the M190. Just make sure that the Vmp is in the 30-35VDC range, and the temp-corrected Voc is not over 54VDC.

Colleagues:

I had occasion today to use the Enphase on-line compatibility calculator.  My client bought some modules and M190 inverters from an E-bay vendor.  The exact module model number was not listed on the compatibility list so I was recommended by Enphase to use the calculator.

The result showed the module was compatible only with the M215 inverter.  Further research revealed that the calculator will never indicate compatibility with M190s even if your module is indeed compatible.  The reason I was given for this is that since Enphase no longer makes M190s the calculator would not recommend them.

This is silly since we still encounter M190s in the field.  Be aware of this situation if you ever need to use the calculator.  I informed the customer support person of this concern and recommended that this tool be corrected to show all compatibilities.  I don't know if they will change this, but I hope so.

By the way does anyone know if the Sharp NU-US235F9 BX modules will work with the Enphase M190? It appears so, but I don't want to recommend something that does not work.

Thanks,

William
