Re: [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!

Sorry,
No, the new IQ and the older M & S inverters are on different comm
frequencies.

Re: [RE-wrenches] Enphase question

[Nick Soleil]

Hi wrenches,


The older generation micros (M190s, M210s, M215s, M250s, S280s) all 
communicated at 144kHz, line to neutral and communicated with the old EMUs, the 
oval Envoys, and the Envoy-S system monitors.


The new IQ micros (IQ 6, IQ 6+, IQ 7, IQ 7+, and IQ 7X) no longer have a 
neutral, so we had to go to a new communication protocol which is 110kHz, line 
to line.


You would need a new IQ Envoy for pairing with the new IQ micros in addition to 
the existing system monitor.


If your customer wants to stick with HIT modules similar to the Sanyo's they 
had originally, then you can pair the Panasonic HIT modules with our IQ 7X 
micros.  We have a module compatibility tracker online here:

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
