Most modified sine wave inverter/chargers are not pfc and one must roughly calculate that a breaker serving the charger
be doubled in current
rating to keep from blowing open. This is due to the distortion of the current
waveform caused by triac controlled regulation. So, if that is O.K. then you have at least made an informed decision.
made (still?) some of the Xantrex regulators and it was their lower end model that I don't trust. I don't know if Xantrex still produces the Incharge as well as the Link series of monitors. I am dubious that their latest battery
monitors are all that accurate but I don't know for sure yet.
WestMarine may still have some Incharge and Link units in their warehouse...would have to check.
