A few years back (like 15-20), a customer asked me to stock a complete board set for the 12V FX in his RV.. Hadn’t heard from him in years so I called his wife.. turned out he died and the estate sold the RV.. So I’m still sitting on a 15 something year old complete board set for a 12V FX (Still in the original, unopened packing).. can’t remember if it was for vented or sealed.. Might be for the mobile unit, so it might switch Neutrals when it locks on to shore power.. Guess I could dig it out and see.. Send me your address.. I’ll send it for free.. The barn could use the space. db

Those relays have 12 to 14 solder points, so unless you have the "Jig" for desoldering them, it's a nightmare to replace without it. You can use the U series to charge like that, but it may not be able to get the voltage to 2.45vpc to 2.5vpc (14.7 to 15volts), and you may not have enough current to charge those batteries by itself in a reasonable amount of time, so do expect long generator runtimes. You may be able to find one out there. They are pretty easy to replace, but you have to take extra care not to pinch the two ribbon cables that attach to them. <http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com><http://www.rollsbattery.com>[https://i.imgur.com/YIluKhq.png]<http://www.rollsbattery.com> Steve Higgins ⋅ Technical Services Manager t +1.902.597.4020 m +1.206.790.5840 f +1.902.597.8447 e [email protected]<mailto:[email protected]> [http://cdn3.iconfinder.com/data/icons/free-social-icons/67/facebook_square_gray-24.png]<http://www.facebook.com/RollsBattery><https://www.youtube.com/user/RollsBattery><https://www.youtube.com/RollsBatteryEngineering><https://www.youtube.com/RollsBatteryEngineering>[http://cdn3.iconfinder.com/data/icons/free-social-icons/67/youtube_square_gray-24.png]<https://www.youtube.com/RollsBatteryEngineering><https://www.linkedin.com/company/rolls-battery-engineering><https://www.linkedin.com/company/rolls-battery-engineering>[http://cdn3.iconfinder.com/data/icons/free-social-icons/67/linkedin_square_gray-24.png]<https://www.linkedin.com/company/rolls-battery-engineering><http://www.instagram.com/RollsBattery>[https://cdn3.iconfinder.com/data/icons/free-social-icons/67/instagram_square-24.png]<http://www.instagram.com/RollsBattery> ________________________________ CONFIDENTIALITY: The information transmitted herein is intended only for the addressee and may contain confidential, proprietary and/or privileged material.

I am hesitant to post here, since I am not really a Wrench. I feel like maybe I can get by with it since I'm so involved with running the list. So ... After many years, my VFX 2812 stopped charging my batteries, but continues powering my home. The VFX 2812 is mounted to a Midnite e-panel, with two PV inputs (MX-60 and an old Heliotrope CC-60), a FlexNet DC, HUB, and a Mate2. A battery temp sensor is between two of my Surrette 2-KS-33P batteries. Some time ago, the red error light behind the clear cover on the inverter started blinking, but it continued charging from our 7 kW generator -- so I suspect it had nothing to do with my current charging problem. Discussing with Bill Battagin, the light was possibly a fan error, apparently a bit common. I tried switching generators, as the first one showed 64 CPS, but that did not help. When I start the generator, the AC In light on the Mate2 on (and stays on), and I hear an inverter relay clicking as if the generator warm-up delay feature keeps going through its cycle. The house lights flicker at the same time as the click, but charging never happens. I've re-seated all the Cat-5 cables with Outback contact goop on all ends, and I replaced the Mate2 cable with a new Outback one. I've checked and tightened all the connections in the e-Panel and batteries. Question 1: So what can I do to further diagnose or even fix this? Buying a new or even used VFX inverter is out of the question, financially. Question 2: I still have my old Trace U2512 inverter. I'd like to hook its charger into the e-Panel, as a temporary situation -- for times like last week when we were fogged in for a few days, letting my batteries get a lot lower than I want. I would not use the AC output on the Trace, but would continue powering my home with the VFX. I figured I would put the Trace battery cables in parallel with the VFX so that the Trace charging will also go through the shunt so I can see the charge rates and levels on the Mate2. The generator's wires would be changed from the e-Panel AC In to the Trace AC In. The last thing I want to do is further harm my equipment. What say ye to this temporary idea? _______________________________________________ List sponsored by Redwood Alliance Pay optional member dues here: http://re-wrenches.org List Address: [email protected]<mailto:[email protected]> Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org There are two list archives for searching.
