So sue me if I measure stuff to see what I have with the new to us rig, and see if it is easy to improve on that.
I am not ignoring everyone's good advice--I am checking to see how well it applies to this particular rig we have.
I do like that 20+ amps better than the 5 or so amps we got with the 7-pin and the 5er. :) That is different!
As stated before, not even sure we will need any alternator charging, never mind how much is enough. Got to get some "time in" with this Class C way of doing things, then see where we are at.
No need to "sue"..
Just pointing out the obvious.
Auto charging systems are not really designed for this, basically a limitation. The result is a few paltry amps going into your house battery.
By upconverting to 120V than back to 12V you are removing the limitations of the alternator's regulator.
The inverter has access to the full capacity of the starting battery plus the alternator max output and the engine.
Your converter now can dole out up to it's max so if you have a 60A converter, it should have no issue pumping 50A-55A into your house battery. Basically doubling the available current over straight DC connection..
By the way, typically accepted that about 740W = 1 HP.
So, if you have an engine rated 300 HP you have up to 222Kw of power..
A 60A converter will draw about 1 Kw of power max at rated output..
Not the most efficient use of a 222 Kw gas engine..
