We have been using the Tripplite 1500XL model for about 6-8 months now and have been happy with them. UPS reports the battery voltage is 54v. The double conversion does draw more power during normal operation but also allows it to continue to power loads even when AC input power is as low as about 60v AC or so without actually switching to battery draw. Only issue has been portable generator power they do not like. Our old APC models we could change the sensitivity to make them work. I have not found an option in the tripplite's.

Was looking at this model: http://www.tripplite.com/en/products/model.cfm?txtModelID=4387 Offers SNMP and email alerts. Noticed the connector on the back. Wander if we can build our own external packs as well? Does this look like the same connector as your units? What did you use for batteries? I am guessing 72 volt? ---------------------------------------------------------------------------- ---- WISPA Wants You!
