Power-Outage Contingency

I had no idea a whole house can cool down 20F or more in 45 minutes...

Two story bi-level built in the mid 50s with no insulation and aluminum framed
windows. I was renovating it and had gotten R-19 fiberglass into the attic and
R-13 into the walls of one of the four bedrooms and into the kitchen. I might
have also finished the main bathroom by that time. The rest of the house still
had no insulation (unless you count the aluminum foil vapor barrier it came with).

Even dropping down to 72 is not too bad.

As I recall, that's about where it wound up.

It has lots of good info and ideas.

"Adding an extra battery pack DOES NOT increase maximum current
the inverter or UPS can deliver. This current limit is based on the
inverter
internal design and electronic parts (transistors, fuses) used to build
it...
Adding extra battery pack will increase TIME the inverter will work
from
the battery with the same load, but will not increase the maximum
load."

I am sorry if my words were mis-spoken and should have been in Watts
not VA,( =0 sorry i respond to this stuff early in the morning).

What I meant that a UPS is a short run item and should not be used for
sensative equipment unless wet or dry cells are being utilized. Then
there is the whole hydrogen buildup issue. The long and short is a UPS
can come with a bad battery out of the box and will degrade over time
just like any battery source. I will not protect my valuable investment
with a 150$ UPS. Even if you dont have a power bump the UPS will still
charge and recharge the battery every day and you will have no idea how
long it will last unless you do a run test every month or so. Even if a
UPS is rated for 1500VA more than likely you should not run more than
80% of full load.

I installed 35 of the 1500VA models at Genentech and I tested each one
for runtime based on a 100VA draw. Each one was different and two even
had bad batteries. After 6 months the times changes, some dramatically
some not so, but the load never did! I will work if it is all you want
to deal with but I dont recommed it unless you get a sreaming dealon a
decent model.

No, it does not really matter here - adding extra battery pack does not
increase the UPS maximum load power limits. It does increase "runtime"
(battery discharge time), which is not the same but you seem to mix them two.

I will not protect my valuable investment with a 150$ UPS.

For that kind of price you can build a backup power source yourself
using large "marine" deep cycle acid battery, AC inverter and a power relay
(the 3PDT kind with a coil designed to work with 120V/AC voltage).
And your "investment", how you call it in a funny way, will be properly
protected from power outages lasting many, many hours...

Everybody will do whatever he/she prefers to do
and what makes sense in his/her local situation...
Properly designed backup power source does not have to
cost a fortune - that is the main thing I am trying to say.

Umm that's what he said.

I wish he would use the standard internet style quoting
instead of "quotation marks". Then it would be easier to
quickly read the post.

I was just wondering: If the power does go out, wont the Rock continue the
natural filtering for a while?
In other words wouldnt a Live-Rock tank and its inhabitants hold up a bit
longer than an electric filtered tank if faced with a power outage?
If the temperature remained fairly constant, how many days (hours) could a
Live-Rock tank go before conditions and inhabitants started to crash?

Bacteria in the rock, and bacteria in filters can't do
much without water flow.
