Thanks, Angel, for the pictures of your system at these sites:

Thanks too, for the description below of your setup. Something very similar 
will fill my needs very nicely. I am presently building a house back in the 
woods about a half mile from the main road where I would have to connect to 
the power grid. I live on top of a mountain and most of the utility poles 
would have to be set in 6-foot deep holes drilled into bed rock. The cost of 
bringing power in to my house would be more than it cost to build the house 
!! I therefore plan on living off the grid. At present I have a 2 1/2 kW gas 
driven generator we used to run the cement mixer and power the big drill 
needed to drill holes for pins that anchor my foundation to the bedrock on 
which it sits. In order to get the certificate of occupancy that the town 
requires, I must have electricity for my submerged well pump so I have water 
to flush the toilet and fill the septic system so they can reinspect it to 
make sure it works the way it is designed to work. I will install your DR1512 
system and then I will only need to run the generator once a day to charge 
the batteries. The rest of the time the inverter will run my computers and 
seismo as well as the refrigerator and washing machine and pump my water from 
the well. Many thanks for showing me this very good way to live off the grid. 
Tall trees surround my house so solar cells wouldn't get much sunlight.

Best regards,
Cap
 
 << AC power comes from a panel with breakers to the knife switch which
 also has 60 amp fuses in it.  From the switch the AC goes to the
 inverter inputs.  The inverter AC outputs go to a panel that feed my
 hobby room and all computers and seismo stuff and several misc. lights in 
the house.  The big red and
 black cables (#2) go to the inverter DC inputs through a fuse and
 through a
 shunt.
 
 When grid power is on the DR1512 is charging the batteries and
 passing the AC to its output.
 
 When the grid power fails or at an adjustable low voltage the charger
 is turned off and the inverter turned on in less than 28 ms, fast
 enough that all of my computers stay alive.
 
 I also have a set of solar panels that can give some charge during the
 day if the power is off and in that way extend about 20% the time that
 the batteries last.  The batteries are GC4 6 volts 220 amp/hour wired
 in series and parallel.  With the monitors turned off I can go 15 to
 20 hours without grid power and with a little bit of solar help, I can
 go longer. My system draws about 15 DC amps without monitors, 25 to 35
 with all monitors on. I have a big monitor that draw a bunch. >>

Angel
