Re: [RE-wrenches] FX inverter shutting itself off
Kinda reminds me of a remote site problem I had down south... Dead winter of course anyway -- new OB VFX7248 (w/ flexnet DC), new 5000 series Rolls (installed Inside) and a new Kohler 10K gen set.. system kept crashing on low battery cutout / gen start error (UU on the gen display)... same story.. 2 hr drive to get there.. hit the reset button.. everything fired up just fine.. two days later, same problem.. then a care taker noticed fresh tracks in the snow out by the propane tanks.. so he set up a critter cam.. sure enough.. seems a neighbor didn't like the gen set noise and took to shutting off the fuel supply.. which caused the gen set to spit out "UU" which requires a manual reset.. a certified letter from the man did the trick... dbDan BrownFoxfire Energy Corp.Renewable Energy Systems(802)-483-2564www.Foxfire-Energy.comNABCEP #092907-44

John,Sounds like low voltage cutouts. And it is the dead of winter so the batts will be voltage depressed. Try installing the temp sensor directly into the FM60 rather than to the Hub. Also, unless those L16s are sealed, maybe bump the absorption voltage up to 30VDC or even a bit more for the winter.Good Luck, Bob-OOn Feb 6, 2011, at 8:21 PM, john wrote: Wrenches, I have a mountaintop transmitter site with an FX3524, Flex Max 60, some PV and 12 L16 Bateries.

Re: [RE-wrenches] FX inverter shutting itself off
Hi John, What is the error code on the Mate when you show up, or is there none? As far as turning on the inverter remotely, I think you would need internet on site from a DC source to let any data monitoring software remotely control when the inverter is off. Is there a back up generator? What does the data monitoring show for battery Voltage around that time period? Best, Jason Lerner Waldron Power and Light Co.
