Li batteries at 48vdc
After much deliberation and questions, I'll likely be purchasing the 48v Lithium battery pack instead of 4-12v. I liked the idea of 12v batteries for weight and ease of handling, but the possible cel...

AFAIK this would only apply to MPPT controllers which have a buck converter in them.
This idea also came up recently where somebody had solar and the power supply and wanted to parallel them into the controller. Discussion of whether to use a 1.2.Both switch or second controller and parallel the controllers. Might have been some "issues" can't recall.
That was the problem, two different supplies , two different voltages into one controller, two Different supplies connected directly together
At night with shore power available, his solar panels would have become a siphon using power from the shore power, unless they were sufficient reverse blocking diodes on the panels
Same but worse than shade on one panel, he would have had all panels in the dark drawing on the converter
No problem paralleling the out puts of different controllers, as the supplies are not connect directly together
Any way parallel subject that's off topic, kinda on a tangent
2old man knows to have controllers for each power source
