Parallel Charge Controllers off of same Solar Array?
Hi, I have an application where there's a large solar array with its own charge controller and lead-acid battery bank; I also have a small Lithium-Ion battery bank of the same nominal voltage, but the actual voltage and desired charge voltages are obviously different. I'd like to tap into the DC bus of the existing solar array to run a separate charge controller for LI battery bank. Is there any reason that would cause a problem for the array or charge controllers? Thanks for any insight; I see a lot of threads about paralleling charge controllers to a single battery bank, but haven't found this question discussed.
