Wow, super system. We live off-grid in our coach FT with only half of that inverter power. 29.6kwh worth of 48v battery power is fantastic - and affordable too when made from prismatic cells. I did the same thing but a little smaller (23.5kwh), but I have an older coach so was fighting a space/weight limit. Really professional install too - well thought out custom layout. I don't think those batteries will ever get below 30% if you've got enough solar on the roof. Mine don't. My wife gave my tool a name; does that count? I think you need to cut back on that magic smoke some, my friend. BTW, I like to eat frogs - tastes like chicken!
We've got one more battery to put in so it will be near 45kw of battery. Yes plenty for any adventure. We'll end up with 2500w of solar hopefully. Thanks for checking in.
@@sotasolar Holy Cow! That's massive. What is that, close to 600lbs worth of batteries? They will never be without power though. I'm thinking about removing my generator to save the 200+ lbs. because I never run it anymore and I only have 1/2 the storage capacity they have. Now you've got me thinking. I could remove my generator and install another 320ah, 48v battery like I have now, adding another 16.4kwh of battery capacity with no weight penalty. Decisions, decisions.
I have watched all of your build videos. What a powerful and great looking system! What are you designing to charge that awesomely huge 48v battery bank? Can you describe how that is charging going down the road? How are you configuring your solar, 48v+ in? Keep up the fantastic videos!
Thanks for the update. I have a question that perhaps might be addressed in your next video (or summary video in part 4). Where are the case/equipment grounds from the Victron equipment connected and what gauge wire is it ? Thanks again!
Yes, still need to run those. I've seen the ABYC guidelines say it should match the gauge of the primary conductors or one size smaller. For us in that cause would be 2 awg.
Hey Shawn, I'm building (well I guess rebuilding) the inverter setup in my RV, so timely video. Love your work as always. I'm curious, with your neutral wiring on the MP's, did you just double land a small jumper wire between the two neutrals and grounds between the inverters? It was hard to tell from the video. I was going to pull the neutral and grounds together in a couple of polaris taps and run that to each inverter. Six of one, half dozen of another?
Only time we’ve seen them blow is for particularly large RV roof ACs can pop a 400a fuse in the Lynx. In that case we went to a 500a . It’s a bit oversized, but we had 4/0 cabling and customer understood the risks. Other than that? No. Other than accidental stuff.
Each one of these batteries is almost equivalent to 3x of the server racks. Cost would be a little more overall. I think in this case the form factor fit the use case so well. It was hard to choose anything else. I don’t think we’d have been able to get 9 server rack batteries in there.
I love the complexity of the layout. Thinking many steps ahead, to come to the proper conclusion. Experience shows.

Thanks for checking in! 2500w solar. No alternator charging. Customer figured, if they need it, they’ll run the generator.
@@sotasolar Thank you for the reply! I'll be on the lookout for the next build video!

Yes I double landed. Doing that way would work as well.
Been following the channel for some time and I like the attention to fusing. Have you seen fuses blow? What have been those circumstances?
Only time we’ve seen them blow is for particularly large RV roof ACs can pop a 400a fuse in the Lynx. In that case we went to a 500a . It’s a bit oversized, but we had 4/0 cabling and customer understood the risks.

Would it be cheaper to use server rack batteries? Or would it be too much vibration? Thanks Don
