Eric, Thanks for the reply. We have the 100W MTR2000 (with the 500W AC supply). This of course requires the 28VDC Argus battery backup unit. It may be a while before we can get one of these units. It's my understanding (and I've not looked into this for a while), that the Argus unit was designed primarily for the AGM type batteries.
I would like to find another solution that won't "void the warranty". If I recall correctly, the manual mentions that the power supply is not capable of charging the batteries. Also, the Argus unit, as I understand it, is setup to properly cycle/condition the batteries, not just float them... I'm still learning about subject though. I already have an anderson power pole connector for this too.
