Just a comment on running my PD9260C 60AMP Converter/charger with my 2KW Honda Generator EU2000i. It runs just fine even in ECO mode. I like using the ECO mode as the speed of the generator tells me what the charge load is doing. I don't think it would be a problem running a PD4645 or PD4655 converter/charger unit.
GOOGLE says the PD4600 series uses the following AC INPUT power
PD4635 550WATTS AC INPUT
PD4645 725WATTS AC INPUT
PD4655 950WATTS AC INPUT
The PD9260C unit uses 1000WATTS AC INPUT
All within the limits of the 2KW HOnda EU2000i generator output specs.
