however, I was trying to figure out how having disparate chargers would work. how do they keep from interfering with each other, if for example, one is a vehicle alternator and the other is a solar panel
what i don't understand is when charging a battery, particularly the last few percent til full, what happens if you have two separate chargers with separate charge profiles
There are many expensive devices that are promoted this way
but in fact they are solutions in search of a problem.
Disparate charge sources of all kinds can be paralleled and concurrently active
without any issue. them "interfering" with each other is from a practical POV just a common myth
yes in theory a complex set of issue
but **not** a problem IRL
Of course, each of the outputs should not be of V / A that would harm the bank.
If your battery is of a type that is susceptible to "too much current" then watch out for the total "amps available" maybe getting too high, but for lead chemistries that would be vanishingly rare, 99.99% self-regulating chemistry there.
As for the charge-termination happening right at the correct endAmps spec point for 100%
again not a problem, 99.99% of the time that doesn't happen anyway 8-D
but whichever source has the best algorithm will be "the winner", as the others drop theirs to Float they are "dropping out of the race"
and only 0.0xx C-rate is flowing at that point anyway.
BTW I highly recommend getting higher quality standalone controllers if solar is important to your overall system
Those included with the newer DCDC "combi" units are sub-par at best, IMO best used just to keep a Starter topped up if the rig is stored where shore power is not conveniently available.
