Ok, i'm really interested to hear from some of you solar gurus on this topic
"Having multiple charging devices connected to the same battery and the same time"
Whether that be 2 or 3 Solar Controllers at the same time, or Solar Controllers + Alternator at the same time, or Mains Charging and Solar at the same time.
Reasons you might connect multiple Solar Controllers might be your Solar Array (panels) exceed the Max wattage the Controller can handle
Hence you run 2 or 3 or 4 in Parallel.
At this point the Battery can be looked as a Load with a Resistance value (talking Lead Acid here, but that may be the same for Lipo, i don't know)
The rate of charge would be governed by the resistance in the battery... And the batteries C-rating or Construction limits.
Is the above possible?
Would the charge voltage coming from one device trigger another device to stop or reduce charging?
In the case of 2 Solar Controllers connected in parallel both having the same wattage panel
Would they charge the battery twice as fast (in basic speak) or would they share load based on resistance in the battery
Or would they compete against each other
Is it just simple Ohms Law?
Hence you can stack chargers and solar controllers in parallel to your hearts content so long as you don't exceed the Max charge limit of the Battery?
For this example, lets consider a Lead Acid or LifePO4 12v Battery with a low state of charge which is ready to accept a bulk charge
