Inverter

[one_dusty_hoot]

Maury,
I don't believe you would be happy with what you propose
to do, here's why. Following are some electrical considerations:

You do not get something for nothing changing from a DC
to an AC current, matter of fact you loose in the loss of
efficiency of voltage conversion. Maybe 10-15% for a good unit.

Consider the perfect world with no loss. Power (watts) is
equivelant to voltage (V) times current (A). For ease in
calculating let's say the AC voltage is 125 and the DC
voltage is 12.5. To obtain 1 Amp @ 125VAC (125 Watts), a
perfect transfer from a 12.5 VDC battery source would have
to deliver 10 Amps, 1250 Watts-100 Amps, 2500 Watts-200 Amps.

At 100 Amps even the slighest resistance to the inverter
will reduce the available voltage in the transfer.

Batteries are rated in Amp Hours, 1 Amp x 1 Hour=1 Amp Hour
You can see that 1250 watts is sucking the battery hard and
this is why it is necessary to have a battery bank capable
of delivering a lot of current.

with my generator and old charger set up, but have been thinking of
getting a 2000 0r 4000 watt inverter and buying a 12 volt battery and
placing both in the driver side rear compartment and hooking it to
the cheater with a 110 connection and using it for quiet time.
Question one-would this hook up provide power to all connections in
coach(understanding one could not use more than unit provides).

long can one do this before the battery charge is depleted? Thanks
