Geez man, give me a chance to change my reply.
Agreement is one thing - impossibility another....!
Nah - the "other" is messy and confused. Too much for me to read over for now - I merely recall key statements that I commented on.
But this one IMO is simple.
Interestingly a related question sprung up on another
forum asking how frequently these systems (dc-dc) are used for THIS sort of purpose.
The OP knows their use & application, but finds this type of scenario puzzling - they find it is usually the available power that is the problem (eg, solar or alternator output) - NOT the voltage.
But he
well knows the Australian situation versus (say) stateside. Over there people just do not fit "capacitors" or "bigger batteries" to power big audio and other systems - they see to know to start with distribution & alternators (eg, "the Big 3" being "grounding" and alt-battery).
And he is
well used to people trying to push bullsh & hype. A few ACCC suits here and there. Wiping out a few wealthy incomes. (It is his $5 "battery isolator system" I use. And he can't figure out why anyone here would have set battery isolation voltages to less than (say) 13.5V let alone 12.7 or 12.5V!! And as to whoever was arguing with me that their ~$100 80A isolator "provided more AH" than my simple isolator.... straight to jail! (That's gaol for us!).)
But for me to pay $200 or $400 for something that only "charges" to 20A when my alternator & $10 isolator charges at 40A, and does not have the same conversion losses? (Do you like losing 10%-20% of power for a conversion?)
I'm keen to clean up a few products and solutions, and enlighten people if I can.
Then I'd like to clean up other discussions and misunderstandings. (So much time to spare, yet none left over!!)
And don't let the occasional agreement get you down. (LOL)
I actually prefer disagreements anyhow because that's where I learn something new or different; have something corrected or qualified; or manage to teach a few....
But that is VERY different to flaming etc. (OldSpark is none too subtle about that either....)
But we both understand mis-communication, and (our own!) bad expression, or not being "obviously" discussing a particular aspect only.
