Since the price difference between the 45 and the 60 is only ~$100, it seemed well worth it. An Ethernet-ModBus bridge would cost nearly that much, and we wanted to avoid extra complexity.
Having the extra controller capacity also allows us to add a few extra panels in the future, if needed, without significant re-wiring. --Eric From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Mike Lyon Sent: Friday, November 08, 2013 9:38 AM To: WISPA General List Subject: Re: [WISPA] Network enabled solar controllers Yeah, that's the downside :( On Fri, Nov 8, 2013 at 9:36 AM, Eric Flanery <eflan...@fsr.com<mailto:eflan...@fsr.com>> wrote: The MPPT-45 doesn't have an Ethernet interface, so you would need an additional device to bridge ModBus. --Eric From: wireless-boun...@wispa.org<mailto:wireless-boun...@wispa.org> [mailto:wireless-boun...@wispa.org<mailto:wireless-boun...@wispa.org>] On Behalf Of Mike Lyon Sent: Friday, November 08, 2013 9:35 AM To: WISPA General List Subject: Re: [WISPA] Network enabled solar controllers I'm looking at the MPPT-45...

ModBus over TCP was a bit of a pain to get working; but once it is setup, it works great. We did have a problem where the units would revert to their default IP addresses, months later, for no apparent reason. All other settings stuck. We worked around this by just letting them keep their default IP, and re-mapped it via NAT at the router. No problems on the charging side, and the custom cutoff feature is awesome. --Eric -----Original Message----- From: wireless-boun...@wispa.org<mailto:wireless-boun...@wispa.org> [mailto:wireless-boun...@wispa.org<mailto:wireless-boun...@wispa.org>] On Behalf Of Mike Lyon Sent: Friday, November 08, 2013 7:55 AM To: WISPA General List Subject: [WISPA] Network enabled solar controllers What is everyone using? -Mike _______________________________________________ Wireless mailing list Wireless@wispa.org<mailto:Wireless@wispa.org> http://lists.wispa.org/mailman/listinfo/wireless _______________________________________________ Wireless mailing list Wireless@wispa.org<mailto:Wireless@wispa.org> http://lists.wispa.org/mailman/listinfo/wireless -- Mike Lyon 408-621-4826<tel:408-621-4826> mike.l...@gmail.com<mailto:mike.l...@gmail.com> http://www.linkedin.com/in/mlyon _______________________________________________ Wireless mailing list Wireless@wispa.org<mailto:Wireless@wispa.org> http://lists.wispa.org/mailman/listinfo/wireless -- Mike Lyon 408-621-4826 mike.l...@gmail.com<mailto:mike.l...@gmail.com> http://www.linkedin.com/in/mlyon
