@Pi Curio Since you asked, here is what it looks like. I've assembled it all just like this, but am still waiting for the battery to arrive -- hopefully this Monday.

@TacomaJoe, there are several things you say here that are interesting to me -- but I'm just not educated enough yet to understand them. I appreciate that you are experienced with a system you feel is working well. Can you give me some more details? Here's what I don't understand: 1) What would...

Thank you for directly addressing my question. The only thing I don't understand about what you've said is, "What is 'a long time'"? A day, month, year? Let's assume I fully discharge a 800Ah battery system. Then according to my (maybe too simplistic) calculations this would mean about...

@DJSmiley I did some research and like your suggestion about a Teltonika RUT50X -- there's a lot to like about this solution, except the price tag (490 euros here). I've decided to get it but wait on the Antenna until I save a little. I want the best and future-proofing with tech like his is...

@sunshine_eggo, thanks for your response but I just don't understand several things you've written here: things like, "0.07-0.20C" , "their rated charge current" "PV" -- but again, thanks for responding anyway.

I appreciate the many posts. Thank you @Zwy especially, giving the numbers based on your experience means a lot to me. As I mentioned, the intention is "full time" van use, so week-long periods without battery use will be rare; for example, when parked while flying off for a visit somewhere. So...

@TacomaJoe -- although what you write here is quite simple, it made me think of a lot of things. Especially the comment about the bare terminal nearby. The value of a forum like this is hearing from people who actually have experience with what's being asked. However, I'm still hesitant about...

There are a lot of battery suppliers in the US, but I'm doing a campervan build in France. As an American it's not so easy for me to buy batteries here and this is a huge purchase for me. I'd appreciate any help. Through another thread I thought I wanted 3 or 4 12V 206Ah SOK Batteries, since...

Thanks @TacomaJoe and @time2roll. After considering all the posts so far, I'm beginning to see what factors are important. Most importantly, I think I will choose 800Ah. Now I need to decide between the type of batteries I mentioned in the original post: two 400Ah server racks, or four 200Ah...

On page 81 of Mobile solar power made easy Prowse writes about 4G LTE Routers with High Gain Antennas and directs readers like me here: "If you want to see what router I am currently using or my SIM card service, check out my website: http://www.mobile-solarpower.com" But I can't find...

I had trouble finding littelfuse distributors, and so I decided to pay the 77€ for the Blue Sea products. Painful, but didn't think it was worth spending more time on it. Thanks everyone for all the help.

@sunshine_eggo thanks for explaining. Unfortunately, your posts are still leaving me scratching my head. For example, in each post you talk about lead-acid batteries and yet my post doesn't mention those at all ("I want to buy lithium phosphate batteries, but need to decide how much" -- I even...

I'm installing a 900W of solar on top of a van intended for "full-time" use. It will also have alternator-based charging, and maybe shorepower someday. I want to buy lithium phosphate batteries, but need to decide how much. My goal is to operate "off-grid" as much as possible, and not have to...

It seems all that thread is about which server rack battery to choose, but that wasn't my question. I probably wasn't clear enough. My question was for advice in choosing between server racks vs. 'regular' batteries and I was referring to my original post where I wrote: I've been looking at...

I want a fuse to protect against accidental short circuit at my battery terminals. I think a "terminal fuse" is what I want for this. I know that there are lots of fuses needed for different purposes, but watching this part of a video made me think a terminal fuse should be my first purchase...

Great specifics in this response. Thanks Perhaps I was hoping too much, but I really wanted to hear from someone with actual experience doing van life within Europe, better yet using the same carrier I am (Orange). I really appreciate all of the replies, and I will look into all of these...

@ShaneC Thanks for answering my questions. Yes I have very good reasons for wanting 3kw inverter power (or at least 2kw). And yes I do understand the need for huge wires with 12V. It's the price I pay for having alternator charging. @Daxo Yes, I looked at PowerQueen -- it's in the @Will Prowse...

I certainly considered going to 24V, and also considered getting a smaller Multiplus. But I made conscious decisions about both of these things after doing the best I could in my research. For example, I went with a larger one because I like to future-proof things as much as possible. It's nice...

Thank you @ShaneC -- I read your comments twice, but to keep things brief, I will only comment on part. I wrote that I want 600-800Ah ("3 or 4 12V 206Ah SOK") and you wrote: So, putting this together it seems that the "3 or 4 12V 206Ah SOK" would work for a 3kw inverter and the 12V 400Ah...

@atelierminceur I ended up taking advantage of Roamer's consulting service, which cost something like €125 but is refunded if you decide to purchase battery / electrical components from them. The major items I got were: a Roamer 460Smart3, Victron MultiPlus-II (12/3000/120-32 230V), Orion-Tr...
