Hello all, and thanks to all that contribute here. I have learned alot reading here the last 2 months. I have come up with a specific question that I had not seen and so this is my first post.
In the example of a solar/electric powered boat that I have seen a few discuss here, I am trying to figure out or find out how to estimate battery life/longevity. I am pretty clear on most of the different aspects of charge/discharge rate, dod %, # of charge cycles and that they dictate how long your battery will last or NOT. The specific question is, in a daytime only system that is producing say 8 amps from the panels (avg) and the motor load adjusted to consume 10 - 20% less, some will say they are running the load off solar and still have a small amount going to charging. That seems to cover the basic reality of the moment, but from a longevity standpoint what are we really looking at? Is the load getting any of the current directly?, or is it all going through the battery and going to contribute to an early death if the battery bank is not sized properly? Is the battery staying charged and just passing it through? Anyway just trying to figure how this relates to what life span to expect from batteries in this situation if they are minimum sized.
thanks for any insight.
