Battery power for big SSTC
Original poster: Matthew Smith <matt-at-kbc-dot-net.au>
Inspired by Dan's 10kW SSTC, I was wondering if anyone considered car*
batteries** as a power source for larger SSTCs?
I am able to get batteries which are not quite good enough to start an
engine but can nevertheless hold a charge, for free. I use a bank of four
to run an ex-telecomms inverter - can give 300W for several hours. This
got me thinking...
A 60Ah battery can deliver 60A for an hour when new. When old, we can
probably still get 60A, just not for so long. If we hook up twenty of
these 12V batteries, we have 60A -at- 240V = 14.8kW to play with. (Yikes!)
Could this be a way of overcoming the limitations of smaller domestic supplies?

* I should really call them accumulators.
