SMA Sunny Island also does this but also discharges battery in parallel with the generator to create a "virtual generator" that is larger than the actual generator. Just set the max generator current and it does the rest.

William Miller At 07:18 PM 1/29/2013, you wrote: This is going back several years... The Outback VFX series lacks the tight input current regulation of the SW series, so the max AC amps in is really just a suggestion. In many cases (and especially with these small generators) we want to set the max amps in as high as possible to minimize charging time and maximize C/rate. Yet a surge load can momentarily exceed the max amps setting. I have observed that the Honda inverter/generators have a quite sensitive AC output breaker, that will sometimes trip if a surge load (such as a refrigerator) comes on during a charge cycle set close to the generator's capacity. This incident was specific to a Honda 3000i. In contrast, Yamaha's EF3000iSE will lug when overloaded - not good for the generator, but also not likely to trip the output breaker. This is a different issue than was being discussed, but fits your question.
