Q: Can this be powered with a Modified Sine Wave inverter ?

Trust the manufacturer on this question. I am using one of these right now with an old Trace SW2512 inverter. Works like a champ!

It should automatically start charging. It remembers the last setting you had it on the last time it was charging.
