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: https://enphase.com/en-us/support/module-compatibility Cordially, Nick Soleil Enphase Energy Product Manager (707) 763-4784 x7267 // office (707) 321-2937 // cell [Enphase_esig_logo6.jpg]<https://enphase.com/> Energy Evolved<http://enphase.com>™ Powering What’s Next™ | The Enphase Energy Management System<http://ow.ly/HbVS3> NABCEP Certified Solar PV Installer #03262011-300 California C10 Licensed Electrician #986315 Texas Master Electrician #284451 ________________________________ From: RE-wrenches <re-wrenches-boun...@lists.re-wrenches.org> on behalf of Jay <jay.pe...@gmail.com> Sent: Saturday, July 7, 2018 8:32 AM To: RE-wrenches Subject: Re: [RE-wrenches] Enphase question Hi Jerry, Can the new EMU work with the older units?

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.

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.
