New power wall Mures
#11
Hi
I will also be using the ME3000PE, just to note: the charge and discharge current on this unit is user adjustable from 20A to 60A. I also plan on expanding my wall, time and availability of cells permitting.

I am building 40P packs and want my charge/discharge current at a max of 500mA/cell as I have two 14S strings (or batteries) ready to go (80P total) I will set the inverter to 40A and then up it to 60A once the next 14S40P string is ready.

I test all my cells at 1C, I'm spot welding a 5A glass lead fuse on the +ve for cell level protection and a cut off lead on the -ve. and so!seeing the other ends to 6mm copper. Since I only plan on pulling 20A from each pack will will be using a 32A DC double pole MCB on each string and a 63A DC double pole MCB between the batteries and the inverter, once I have all my strings in place i will up the main breaker to 100A as per the Sofar installation manual.

I will also be making use of the TOU setting to charge my batteries from my E10 off peak during the winter months with limited sunshine.

Edit, oops apologies i just noticed on your earlier post that you had already seen the option to set the charge/discharge current.
UK Southwest.

6 kWp Solar Panels
APS YC500i Micro Inverters.
Still sourcing and processing cells for powerwall.
Planning on a Sofar Mass Energy ME3000SP AC coupled grid tied inverter.

Glade to see you will use the same inverter.
Just a quick question, do you think copper wire from Cat5 ethernet cable will be ok to weld on -ve ?
