Homemade Powerwall

I thought I'd start a thread on home made DIY power wall using LEAD ACID batteries.
Charge up the batteries when hydro rates a low and use the batteries to power part of the house when rates are high.

How many and what type of Deep cycle batteries would be needed?
Best inverter to use?
Best charger to use?

I know a lot depends on how big or how much kw load you want to run.

I put together a small backup system using 4 golf cart batteries, 1500 watt modified sign wave inverter and an automotive 12 volt charger a few yrs ago.
Found that it would run my washing machine for 3 loads no problem.
It also gave me power to run the fan in my wood stove so I had heat if the power went out.

I'd like to hear what has been done, how much it cost to setup, and the results you got.
