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). 17.25 amp-hours / 40A inverter/charger rating = 0.43h recharge
Operation
Turn ON the inverter:
Turn ON/OFF switch on the front panel. The GREEN LED indicator light will
light verifying the inverter is receiving power.
Turn OFF the inverter:
Turn ON/OFF switch on the front panel. 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.
Turn Inverter ON/OFF Switch to the ON position
Turn the appliance ON.
To disconnect, reverse the above procedure.
Power switch can be off when you only use the USB output ports.
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
inverter does not have to deliver the starting current for all the loads at once.
