(mathematic example: a drill requires 1.5A  0.5A x 230Volt = 115Watt.  No
problem to use the drill.)
 Remember the vehicle's battery will be discharged when the vehicle is not
running.
 To Determine DC Battery Amps Required, divide the total wattage
required (from above) by the nominal battery voltage to determine the DC
amps required. 115Watt / 12V = 9.58A DC
 To Estimate Battery Amp-Hours Required Multiply the DC amps required
(from above) by the number of hours you estimate you will operate your
equipment exclusively from battery power before you have to recharge your
batteries with utility- or generator-supplied AC power. Compensate for
inefficiency by multiplying this number by 1.2. This will give you a rough
estimate of how many amp-hours of battery power (from one or several
batteries) you should connect to your Inverter/Charger.
9.58A DC x 0.5h runtime x 1.2 inefficiency rating = 5.75 amp-hours
 To Estimate Battery Recharge Required, Given Your Application You
must allow your batteries to recharge long enough to replace the charge lost
during inverter operation or else you will eventually run down your batteries.
To estimate the minimum amount of time you need to recharge your batteries
given your application, divide your required battery amp-hours (from above) by
your Inverter/Charger's rated charging amps (depending on the ON/OFF
settings).
9.58 amp-hours / 40A inverter/charger rating = 0.24h recharge
Operation
Plug in the inverter. The RED LED indicator light will light verifying the inverter
is receiving power
Turn OFF the inverter: plug-off the inverter
When you have confirmed that the appliance to be operated is turned off, plug
an appliance cord into one of the 230V AC outlets on the front panel of the
inverter
 plug-in
 Turn the appliance ON.
To disconnect, reverse the above procedure
Note: If you are going to operate several loads from the inverter, turn them on
separately after you have turned the inverter on. This will ensure that the
