Hi Wheels and Hud,
Thanks for the replies, The reason that I have asked the question is that my 3 stage regulator
(not from balmar), does not seem to output as many amps if the batterys have recently been charged from another source.
In bulk/boost mode, my fast charge 3 stage alternator
regulator does not seem to sense battery
condition correctly it senses only the voltage, I think it somehow should also sense the potential for more amperage acceptance and then calculate the amperage to deliver.
A Senario -
bank discharged by 50 %.
or wind generator
are charging the battery bank or maybe the AC generator
which runs the AC battery charger
has only just been switched off after cooking
(The result is that the battery bank shows a voltage that does not reflect the true amount that the battery bank is discharged.)
is now started and the 3 stage regulator reads the voltage and
decides how many amps to deliver.
(as the voltage reading is higher than it should be at start up, the 3 stage regulator does not deliver as many amps as the battery could potentially accept.)
On my boat in this senario the alternator puts out 50 amps instead of 100 and takes very much longer to charge fully.
My solution is to have at least 20 minutes gap and some load on the battery bank after switching off the generator
and then starting the engine
I only have a generator and no solar or wind
, so I imagine boats with these alternatives have the problem that they cannot easily switch off battery charging.
After looking at the link from Hud, it looks like the balmar
regulator might not have this problem.
If all regulators only sense the voltage then I could imagine that they all would have this problem.
I hope that makes it a bit clearer as to why I asked.
