New RV system

[TCgreg]

Built in the basement of our new 5th Wheel. The stock wall was moved and all components mounted on newly claimed space. (Blue tape shows old wall layout. The battery bank slides in under the staircase to the bedroom. Time to hit the road. ;-)

600Ah CALB 3s/8p w/ Daly 200Ah@24v BMS
(12) 200 watt 24v Newpowa panels in 3s/4p
Victron 150/85 Solar charge Controller
Magnum 4000 watt inverter
DIY combiner box

Beautiful! Well done, very clean

Please help me here : Your battery bank is 3S8P which means 8 parallel strings and each string contains 3 cells in series. This combination will only yield a nominal battery voltage of 3 x 3,2v = 9,6v or am I missing something obvious ? 4S6P will make more sense to me or do the CALB cells have a higher nominal voltage e.g. 4,2v ?
or is it 8S3P for a 24v system ?

Man, that is clean and beautiful. Keep an eye on that 3" ABS. Those connections can wiggle loose over time from vibration. You don't want your system to go to s**t.

My typo. Should be 3p/8s. I don't seem to be able to edit my original post. Thanks for pointing that out.

Do you have a link to your tray setup, that’s slick!

Very nice install indeed. Enjoy boon docking - you are kitted for it !

Looks super clean. Well done!!!

Is there anything to stop the cells bouncing up?

I’d cover those top connections more if it was mine. Lot of power stored right there. Any short would get a bit wild
