Seeking Advice: Low Voltage vs. High Voltage Batteries for Home Energy

Thanks, should I think about the dangers of high voltage differently on the storage circuit vs generation circuit? I suppose if a DIYer is willing/planning to go well over 100v on panel strings, then they should also be willing to go >>48v on the storage side, assuming they follow the same precautions (dry hands, thick soled shoes, rubber gloves) as you do on the
