Hello group:
We have been looking very closely at micro inverters for a number of reasons. Some of those would include:
-variations in panel orientations (ground/roof mount, portrait/landscape, south-facing/west-facing, etc.)
-mixed panels (such as the Jinko 72c/310w, 72c/300w, etc.)
-snow/shading possibilities
-etc.
Possible installation sites would include southern Utah, which means wide fluctuations in temperature, such as 100+f in summer and even -30f in winter.
We've researched micro inverters and power optimizers from different companies. The SolarEdge P400s look like they could work in aforementioned scenarios. However, the YC500 inverter (http://www.enfsolar.com/pv/inverter-datasheet/1543) seems like it would also work. Not only is it specified to handle the hot/cold climate, but it also looks like it should handle the big 72c/310w Jinko panels even in low temperature/high output conditions. Data I have on the 310w panels indicate a max current of 54.3a, which is within the microinverter spec.
We've also looked at the Enphase 250 inverters and the Enphase C250 also looks like it should work. However, it must connect to 3-phase power while the YC500 can connect to split-phase 240. Enphase said over the phone that their M250 paired with the big 310w Jinko panels would probably fail when the temps dropped to a point where the panels become most efficient.
If anyone has experience using/installing microinverters and panels in similar climates (especially very cold climates), please lend your opinions. Thanks.
