Hi,

Considering to upgrade by batteries. My currently setup:

Pylontechs

3 x US2000 50ah

1 x US2000C 50ah

1 x US3000C 74ah

If I add 2 more US3000c's it will take me to 20.1 kwh, at 322 ah.

How does this compare to 4 x 5.1kwh 100ah batteries? Is there a big difference, noticeable for avg household?

Current setup has on avg 700 cycles and 96% SOH. I considered selling the stack but secondhand market filled with scammers and bargain hunters. The price difference in expanding vs new is R25k +. The current stack served me well, is the money worth the real benefit if any?

I would just add. Why buy 4 new batteries? Kwh is Kwh as far as I am concerned

well you can have a 422Ah 48v 20.2kWh battery and save R25k

or have a 400 Ah 51v 20.4kWh battery and spend R25k

now the question... is R25k worth 0.2 kWh
