In my last post on Solar panels, Stu made a good point of overpowering. Does anyone have experience with controllers that hare hooked into the battery along with the battery charger(when plugged in) and also the alternator when the motor is being used?
Appreciate all comments.

I have hundreds of boats as examples.

There is no such thing as "over-powering".. When the banks are in BULK all charge sources will contribute to their max ability. When the banks reach absorption the controller, regulator or charger with the highest absorption voltage, even by a hundredths of a volt, wins and will become the default voltage limiting charge source, if its amperage can support it at that state of charge. If the charge source with the highest limiting voltage does not have the current to support that voltage then voltage will drop back until the other charge sources kick back in.

Remember the battery bank decides what it takes at a specific SOC and voltage. Chargers, controllers and regulators regulate voltage, the battery dictates how much current will flow at a specific SOC and voltage.

I made this video for my world cruiser friend/customer Ed..... It may help folks understand the relation of voltage & current...

I have 2 battery banks.  I am only going to use the solar panel on my house bank.  The house bank is made up of 4 Trojan T125.  Will not be using a combiner.
Thanks,
Paul
