positive ground update

installed a flexmate 80, what a difference!. batts at float by 1pm, going to add more batts.
I now have 3 panels that are not being used (sunpower 48v 215 watts) the ground problem ( +) if I understand what i have read, is not going to be a problem at this voltage,?, 48 to 12,
I have been playing with the 3 extra panels by cutting them in and out of the circuit to keep the 80 at 75 amps output, early am, cloudy days,
is there a device to do this automatically
thank all of you for the help, SAM

I see this was ten years ago. You still with us Sam?
Also I’d like to hear how your life is going with that positive ground system. I’m knowingly walking into one now.
I would not recommend doing this if you can't keep an eye on things all the time. If I have to leave for any reason I assume that I will get full sun and switch out the extra banks.
