Run the DC straight to a breaker in the power center. Use a voltage
sensitive relay to stop the generator when the battery voltage gets
high. <br><br>

They show them as being used specifically for off grid solar applications
including remote homes, but I'm with you, I don't understand the voltage
limitation. <br>
They seem to think they are just replacing the battery while running, not
actually charging it. Very weird. I even went through their case studies,
and I'm wondering if they might end up with some long term sulfation
problems. It seems they're only interested in reducing the battery size,
not augmenting the PV charging; seems a waste of fuel.<br><br>
I linked to these for Allan earlier just as "food for thought"
I wasn't actually advocating their use. It does look like a decent
generator, so possibly the voltage limitation could be overcome?<br>
I remember another DC gen set, that ran a Honda motor to belt belt drive
a truck alternator (late 90s). I recall them being something of a
pain.<br><br>
Here's another that looks interesting, and actually can be adjusted up to
64 vdc:

Once again, I'm just sharing the info, not advocating these.<br><br>
