Hello, Jeff & All~ In the world of high end yachts, the crew needs to be able to plug in and charge in various regions of the world. Some marine oriented battery chargers are "universal input" & designed to run from 90v to 265 volts, 50/60 hz according to one spec sheet for the Victron Phoenix. The actual frequency tolerance may be more wide than what the specs say; check the manual to be sure.
Jeff's suggested strategy puts the charger/battery/inverter in between the messy grid power and the loads. It's sort of a power quality buffer. The Wrench List is the Bomb! Mick Abraham, Proprietor www.abrahamsolar.com Landline: 970-731-4675 Cell phone or for text messaging: 970-946-6584 ᐧ
