<p style="margin-top:0;margin-bottom:0">Hi wrenches,</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">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.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">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. </p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">You would need a new IQ Envoy for pairing with the new IQ micros in addition to the existing system monitor. </p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">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:</p>

<div dir="auto">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.</div>

I have a legacy system with 12 Sanyo HIT 215N panels and Enphase 210s. 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 dont do a lot of grid tie and this hasnt come up before.<br>
