Good advise Perry.
Being an electrical tech. myself thats exactly the way i would do it.
The advise in not using the 24v to 110 volt inverters is important if you want to conserve battery life and not risk electric shocks.
It is even more "power hungry" in countries that have 240volts as their main power (like we do).
(you need to keep the battery power available for doing "drifts" in shopping malls dont you Glen
)
cheers and good luck with the work Perry
