If I get it right then each cell pack is 100Ah so the end result is 48Volts @100Ah . That means its feeding 48 Volts to the inverter at say what 10 Amps or so in normal use so 480 watts . Surely that wont run much . What am I not getting right here?

My first packs were 100 Ah
These are 250 Ah with two strings : 500Ah
The main fuse is 250A
250A x 56v = 14 000w peak Wink

Ok so just for interest how much do you actually pull off the system in a normal day?

I would say 7 kWh.

What do you think the total cost of this project is so far? Smile

I would say 7000 euros, for now...

Really love the setup and design, nice and neat, nothing out of place, its a real work of art

 I do have a question though, I know u said ur busbars were 1.5mm2 copper wire, and they look like single core stuff, any chance I could get you to measure the cross section thickness?? I want to work out if my 1mm thick single strands will be enough to handle the loads required on an 8 cell per strand basis like urs are arranged

Thank you very much Smile

My old packs had 1.5 mm² busbars, these bigger packs use copper from a 16mm² 7 wires stranded cable.

16mm²/7= 2,3mm² (1.7mm diameter)

I run 20 busbars on my packs, this give me 46mm² at the ends of the pack Wink

Mine will only be 15 busbars as I'm only doing 120 cell packs, but very useful information, I take it they don't get warm at all?
