Xantrex transfer switches are a known weak point; they often fail. That may be the problem, i.e., yours is intermittent (works at home, but not on the boat). I just pulled one out of a 46-footer that exhibited that problem (2500W inverter/charger). Owner decided to replace the unit with a Victron MultiPlus inverter/charger, which is working well.
Another possibility: some chargers are very sensitive to FREQUENCY...if you don't have very near 60 cycles coming from the genset, or if the voltage and frequency are jumping around due to a faulty voltage regulator circuit, the Xantrex may be rejecting its input.
The Iota option is probably a good one. The price-point might be to use two 75 Amp DLS-75/IQ4 units which can work together....150A. They run about $300 each at Arizona Wind Sun & other outlets. Even less expensive would be two 55A units (110A total) which could be had for about the price of one 75A unit. Be sure you get the IQ-4 smart charge adapter if you decide to go this route.
Good luck,
Bill
