[RE-wrenches] Enphase question

[Ron Young]

Hi Nick, so if I understand you correctly then I can find some older Enphase units (I know where I can get some 250’s) and they will integrate with a couple of new 265w Hanwah Q Cells, no problem. I could just plug them in then add them to the existing array. The existing Envoy and 210 Enphase units will not have any issues etc.?

Thanks!

Ron

>> Thats a good thing with enphase, mix and don't need to match, you will need inverters that connect in line or just seperate them with a combiner/subpanel. You will need to stay away from the new Q inverter series as its on a different frequency for comms, 190's 210's 215's and as l recall the 250's all on the older EMU, they are getting harder to find but im sure there are some out there.

Are there any concerns with mixing Enphase inverters on a single string, e.g. adding a couple of 265w panels and appropriate inverters? We don’t do a lot of grid tie and this hasn’t come up before.
