[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:

Cordially,

Nick Soleil

Hi Jerry,

Can the new EMU work with the older units?

Jay

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.

I have a legacy system with 12 Sanyo HIT 215N panels and Enphase 210’s. Client wants to re-do roof and add two more panels when the system is re-installed. 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.
