Now for the fun part. I started to play around with suitable positions of the BMS, Fusebox and Breaker (shunt trip). I am using 70mm welding cable I obtained from Metalland and terminating with Cabec 70-8 cable lugs and covering with heat shrink.
My shunt trip operates from 48V making it easy to power. I added some wire with Ferrules, drilled a hole in the side of the breaker and fed the wires through. I also tied a not in the wire on the inside of the breaker to stop it pulling through.
After watching Lithium Powers youtube video I got motivated to start the BMS Balance Leads. I purchased some ring terminals and using some wire sheath I got from China months ago I started work.
Now that all the threaded rod has been cut and the mounts secured to the two shelves it was time to start assemble the 7 towers. I assembled the towers using the highest rated module on cell 7 and working down to cell 1 and then working backwards till all 7 towers were complete. Unfortunately,…
Tonight I spent about an hour cutting threaded rod to length (just about 1m) This should allow me to mount 200 modules if I use all 8 stacks. This requires 32m of threaded rod. I had all but the last 8m of it, so I cut it all and then test fitted a module on…
I bit the bullet today and purchased the following equipment for my powerwall Victron Multiplus II 48V 5000 Victron Cerbo ET340 – 3 Phase Power Meter 3 Pole fuse holder/isolator
The original plan was to use a rack cabinet to hold all the modules, however, I now have to many to fit into the rack and so another solution needed to be found. I considered standard ‘shed’ style shelving however it didn’t solve the problem of having the modules locked away (so kids etc cant…
