We use the 1500 APCs (non SMART-ups), but when the batteries are at the end of their life, the entire unit shuts off and we have to visit the site. We still continue to use them until we find something better, but at about 3 years, expect the sites to randomly shut off.

Those units are quite good, but they're AC/DC/AC/DC from utility to your radios. I think 80 watts gets you an hour of uptime? I've never had a unit go bad, I always buy refurb'ed units and new batteries. Running three of them for a couple of years now.

They used to be Trace Engineering. They make a decent inverter. Tripp Lite makes some special high quality high reliability inverters for things like ambulances if you need something a cut above. The cream of the crop is the Outback.

It's not pretty but I have had no power drops in a couple of years. Since the unit is designed for RVs etc, it will keep the 12v pile charged even in the face of 12v drain, so you can drive both 120vac and 12vdc loads off the same setup. It will charge the batteries when they need it and ac is available, and float them after they are charged, and use the batteries to provide ac if the mains ac disappears. You decide how big a pile of batteries to attach... On Tue, Sep 20, 2011 at 12:59 PM, Patrick D.

We have found, and verified with roc-noc and some others, that many of the MT boards will get hot with 24 volts to the DC jack and lockup and other weirdness.

Our current configuration is that we have tripplite smart 500VA rackmout UPS connected to deep cycle marine battery. This seems to work OK for a month or so and then kills either the battery or the UPS or both. We then notice that the equipment at the tower will power off (battery shuts down for about 10 min) and then powers back on. This happens almost daily and in some cases multiple times in a day. I think it may have to do with the output volts of the battery not being high enough for the UPS to operate. We are desperately looking for other alternatives to what we are doing to resolve this issue. Most equipment will operate at 12/24 volt. 1x Mikrotik, 2x Trango AP, 2x Trango Link45, 4x UBNT Rocket. Any suggestions are appreciated. Pat Csweb.net <http://Csweb.net/> ------------------------------------------------------------------------ -------- WISPA Wants You!
