Re: [Electric Boats] newbie charging question

 

Fumeless,
Your questions are good.  I would rather answer 10 "over-thought" questions, than repair one under-thought accident. 
 
The "smart" chargers you may be referring to, monitor the power in milliseconds and adjust to a "sync" point in less than a second, ... usually.  I have seen this on land-based home systems where there are 3 entirely different power inputs.  The short non-PC answer is: they are "Conservative" chargers and do the job without getting in the way of the others, and not asking needless questions only to offer useless answers...  Sorry, I had to interject a bit of political humor.  "Dumb" chargers are far less available in these systems, and even they can have a tendency to sync with the rest of the system.  Your best money will be to talk to an experienced installer.  I see all too often, DIYers and the other less experienced, clutter the systems up with needless components that really only serves to weigh the boat down.  That is my two-bits worth, and it is worth just what you paid for it.

Ok, thanks all.
Filtering all the feedback, I get the takeaway that my setup should be fine, but I need to turn off the solar system when using the AC charger (dockside or generator).
That being the answer, I should better restate the question: These charge controllers (solar and AC) both try to do "Charge profiles" where they hold higher voltages for a period of time and then float them. It seems as if two chargers doing that at the same time would confuse each other possibly resulting in over charging or potential degradation of battery life. Similarly the chargers could gen confused in their charge profiles if they are trying to detect charge profile transitions while I am simultaneously varying the power to the drive motor (or getting a slight regen from the motor while the solar system is trying to charge).
Apparently other members have not observed any such problems, so I am just overthinking it.
