Re: (ET) UPS
I use a Tripp Lite PowerVerter Alternative Power Source (APS) 3636VR
which can function as an extended run UPS system or as a mobile DC to AC
power inverter that will recharge its battery source. This is pretty
close to what you are looking at, minus the extra smaller 36v source. I
have had this for approx 3 years and it works great...also used it to
power my house a couple times for parts of a day. If I had to do it
again, I would look at the 2400 watt version and see if Tripp Lite could
modify it to run on 36v VS. 24v. The new multistage regulated chargers
in these inverters are definitely better and more efficient than the
Here is more info on my setup:
Hope this helps.

I've been toying with the idea recently of getting a medium size UPS that
runs on 36VDC. The idea is to get a unit with its own battery, but also
has an external battery interface to hookup to my ET's battery pack for
backup power to keep some computer/networking systems I have at home
always on (my phone is VoIP, plus 2 servers and a PC).
I've been looking at several Tripp Lite models that are known to operate
on 36VDC and have an external battery pack interface.
In particular, I have my eye on this model...
I know UPS's always want to control the batteries attached to them, and thus will
charge them when they get low. I also know that in the various "hot swap"
UPS models, that when batteries are disconnected, the UPS's still function without
My questions to the ET group are:
(1) Has anyone successfully used a UPS to recharge the big batteries of an
(2) Is it better/worse than the stock charger in an E20? With Landis
(3) Does anyone know where to get quick disconnects for high gauge wire,
required for a 36VDC external battery hookup?
Note, I have not looked at inverters, because the idea is that a UPS would
remain functional (on main power) and have its own internal battery when
the ET is disconnected and in use. When the ET returns, at first the ET
would recharge off the UPS, and when needed it would provide extended
battery run-time for especially long power failures (such as the wires in
front of the house being damaged, which has happened to me and caused a 4
