Default On-board generators

It turns out to be a lot worse. The Heart Interface inverter/chargers
are not corrected for power factor. As a result they present a highly
inductive load to the generator and the result is a waveform which
tends to change shape under load. They are VERY tough on even large
generators. My previous boat had a new 7.5 KW gen set which could
barely keep up with the KVA demand from a 150 Amp Heart Interface
charger. Heart recommends something like a 10 KW generator to supply
the 1800 watts to the charger.


Ouch! Is there a smaller charger - perhaps 50 amps - that might work

well with
the Honda 1000?

Based on the description above I suspect the Heart Interface charger is new
technology, based on a switching power supply similar to a computer power
supply. An old technology, transformer based battery charger would probably
have a much more forgiving power factor and would run fine on the Honda.
