Maybe a different question. If your genset doesn't put out pure sine wave power (seeing some of the other posts), maybe useful to ask ProMariner again:
"Is this charger expected to work well with genset power that's not pure sine wave?"
"If not, would the symptom be power spikes like I'm seeing?"
Or something like that...
I'm a firm believer in manufacturers knowing their products, and my expectations are "usually" met OK. Pester then to death, if necessary. (I haven't had to do that with ProMariner, though.)
