Re: [RE-wrenches] Trace SW 4048
Marco, Can you be more specific when you say not producing PV power? Do you mean no AC output? Given that these are battery-based inverters they’re not dependent on the PV to be present in order to operate. What state are the batteries in? Is the voltage stable when the inverter is in invert mode? > On Aug 1, 2020, at 12:37 AM, Marco Mangelsdorf wrote: > > Aloha all, > > I’ve got a pair of Trace, yes Trace, 4048s in a NEM system circa 2001. > > While I can’t find anything demonstrably wrong after hours of > troubleshooting, these buggers just don’t seem to be producing PV power when > they should. > > I’m looking for a greybeard out there who’s well steeped in this fine > dinosaur for additional guidance, please. > > Please contact me off list. > > Mahalo, > marco > ___ > List sponsored by Redwood Alliance > > List Address: RE-wrenches@lists.re-wrenches.org > > Change listserver email address & settings: > http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org > > List-Archive: > http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org > > List rules & etiquette: > www.re-wrenches.org/etiquette.htm > > Check out or update participant bios: > www.members.re-wrenches.org > rick brown SolShine Energy Alternatives, LLC Electrical & Solar Contracting Services www.SolShineEnergyAlternatives.com Check, Virginia 24072 540.808.9502 VA Class A Contractor Lic# 2705147660 VA Master Electrician Lic# 2710062762 VA Alternative Energy Systems Installer NABCEP Certified PV Installation Professional 110112-21 ___ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org

Re: [RE-wrenches] TS4R-F Feedback
We’ve had good experience with the TS4R-Fs. Straightforward installs although wire management is more cumbersome than micros. Since they’re Sunspec compliant no need for a separate RS initiator. AC disconnect is all that’s required. Too early to give feedback on long term reliability. Hope that helps. rick brown SolShine Energy Alternatives, LLC Electrical & Solar Contracting Services www.SolShineEnergyAlternatives.com Check, Virginia 24072 540.808.9502 VA Class A Contractor Lic# 2705147660 VA Master Electrician Lic# 2710062762 VA Alternative Energy Systems Installer NABCEP Certified PV Installation Professional 110112-21 > On Jul 18, 2020, at 11:30 AM, AE Solar wrote: > > > Wrenchers, > Does anyone have feedback on using TS4R-F for rapid shutdown?
