A lot less than you elude too, the biggest reason is typical lithium gives up twice the capacity of a traditional battery at half the weight of a traditional batteryHow much does a typical off grid capable electric installation weigh?
A couple of lithium batteries, all the various controllers/charging systems and solar panels must add up to a significant weight.
I assume most of that would become redundant although some kit would be needed to provide 12v DC and possibly 230v AC.
Very interesting to see how this evolves.
So, say a couple of 100 amp leisure battery weighing circa 25Kgs each could be replaced with one, 100 lithium battery weight 13Kg and would have pretty much the same “real life” usable power
