[RE-wrenches] Husqvarna 5500 and VFX3524 Compatibility question

[John Berdner]

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,
Yes, that's my understanding. Outback acknowledged this to me years ago.

Could it be that the SW systems are protecting the generator with Generator Support, and the Outback inverters are not?

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.
