From: Af [mailto:[email protected]] On Behalf Of George Skorup Sent: Saturday, May 20, 2017 3:55 PM To: [email protected] Subject: Re: [AFMUG] 24V Battery Revert and Charge Module List price on the BCMU360 is about $215 IIRC. I think we pay about $175 from PSUI. Plus $15 for the temp probe. Are you asking run time? I have a couple with 40Ah of battery attached. A few with about 90W load have ran for over four hours, but they never went down, utility came back. A couple others with ~190-220W. Lost utility at one of the sites the other day. It was running for about an hour and a half before I brought a portable gen out. That site didn't go down either. Couldn't let it, too much traffic. And of course utility came back 15 minutes after I got the generator going. On 5/20/2017 4:51 PM, Gino A. Villarini wrote: How much are you paying for the Traco and how long does it last?
