Ok my tank survived the great blackout of 2003 that hit the east coast.
Well After the 18 hour blackout I knew my little APC 250 that lasted for about a 30 minutes was not going to cut it. So it time to upgrade!!! I looked at getting a huge APC that was in the $1500 range ,but it still going to give me only 1.5 hours 2 hours max of runtime. An a generator was not an option since I live in an apartment building. So I did a little research and saw a system that 'David Playfair' made it used a deep cycle marine battery and inverter and a battery charger. This was a great setup.
Here is his idea.http://members.localnet.com/~playfair/bb/ups_iso1.jpgPlayfair Plans
Check out my new DIY power back up!
The quest was for a reliable, cost effective backup system that would come on automatically in the event of a power failure and run my MAG18 return pump for 8 hours...
The result cost under $175 total, and consists of a 95ah deep cycle battery, power inverter, automatic trickle charger/maintainer, and a DIY transfer switch.
The heart of the system is a transfer switch that consists of a relay normally energized with house power, and when that is absent, it turns on the 300w AC power inverter, and sends that power back up to the outlet.
So after speaking to David Via email I was going to take his system to the next level.Here is my idea.
1)Using a commercial made inverter,charger and transfer unit in one box.
2)Use three huge deepcycle marine batteries
3)put it together and get 20 Plus hours of runtime.
Step one: locate the inverter that can do all this for under $1000.
Solution= Trace Model TS 512 SB Inverter/Charger/transfer switch.
The trace 512 is able to deliver 500w of inverted power. Now any one that knows me knows that i don't just get some thing that does the job I always have to do it better. So I opted for the Trace 812 fan cooled model which outputs 800w of power.

Step Two:Locate an affordable deepcycle battery!!!
Solution=EXIDE NC-27
The EXIDE NC27 is unique in that it can be left uncharged for extended periods of time and fully discharged without suffering any performance loss or shortening battery life.
I picked upped three of these 100AH batteries (300ah total) at a local Wholesale clubs called BJ's

I well be installing it this week and will keep you up to date.
