OMG, partspicker solar edition would be awesome! There isn't, well I haven't found, any one definitive guide to setting up solar. After looking into a small system for my van off and on over the last several months, I stumbled on Will's DCC50S video and joined, and now joining makes me feel...

Thanks, looks like the decimal point got lost in the translation, phew!

I hear you, even after looking around quite a bit and being a little familiar with components, it's mystifying. Watching videos or searching for installations hasn't helped as it seems all results are for over the top megawatt Sprinter van setups. I just want some 411 on a basic system in my wee...

Reading my mind, I was just looking into the differences... Looking at 200AH so I have an easily usable 100AH

Here's something interesting I came across a little ways back. https://www.verywellhealth.com/learn-to-play-the-didgeridoo-to-treat-sleep-apnea-3015177

Interesting, I'm looking forward to the results. While I have a ResMed unit, my sister has a DreamStation she never uses and even said I could have before I got mine through health care. Oh yeah, so I'd like to see about a head to head on 12v consumption.

Thanks Snoobler, I'd ended up going with one of those batteries I'd linked in my other thread. I found something that said cells should be top balanced before connecting the BMS and in searching I came across Will's video on it a couple days ago then this thread. I have an RC/hobby charger I...

Ha, same, but the didgeridoo may be fun to take up while I'm out vanning around the country ;)

Not necessarily, in the case of a previous post, dude had his starter battery drain attempting to charge the house battery. While the system seems to be generally decent, if you look above at my previous post 503 you'll see a quick rundown. I myself haven't purchased yet and am thinking I'll try...

This too is a primary reason for me having a house battery system for my CPAP machine but will use a 12v power supply cable. 110v test lower than expected but i will have to test again using the humidifier. I'm guessing that's what you mean by heater? Mine I can turn it on and to a specific...

Thanks DT, that helped quite a bit. I was thinking along those lines and confirmation was great.

From what I gather It must to be able to charge LiFePO4.

Nice to hear some first hand experience! I'd come across something similar after seeing this video and dreams of DIYing my own house batter ran through my mind.

Okay, so whichever DC-DC charger I go with, I need to verify my alternator is happy providing X amount of amps, yes? Zil, what special stuff do I need? Thanks guys!

Could you add a second relay so that when the key is off, it disconnects the starter battery?

Actually, one more question about calculating charge time. Certainly a 50A charger would charge faster than a 30A, but how much faster? Maybe saving $50 on a charger is worth an X minute longer charge...

Your diagram is pretty sweet, what'd you use to make it?

Hey hey all, so after some planning, searching, and figuring I'm close to knowing what I want but would like to run it by some topic knowledgeable folk. I am on a budget as I'm unemployed and working from limited savings, but am willing to spend where warranted. Any input, criticisms, or...

Okay, great. So let me ask this and veer off topic a little. Instead of the DCC50S, could I just use a regular DC-DC charger and relays to select + input from solar or alternator pending the state of the ignition switch?

Well, nobody's saying no, so I'm guessing it's a fairly sound start.

For my install a fuse box with terminals on the backside would be the bee's knees. However, after searching around yesterday I only came up with one: https://www.amazon.com/dp/B01N25TJV3/?coliid=INV7Y8BWZWUVH&colid=2KPBM55BS504P&psc=1&ref_=lv_ov_lig_dp_it Figured I'd check to see if anyone knows...

Yeah, but seems they are all in China? I'd prefer something US based, or at least US inventory for a first time experience with all this. Mainly for quicker initial delivery and in case and warranty issues arise, hopefully a replacement would only be states away instead of the other side of the...

Contemplating going with them, do they look like a good deal, anything I should ask or look for? $70 cheaper than the 120ah batter I'd been looking at, plus no sales tax. https://washingtondc.craigslist.org/nva/for/d/fairfax-lifepo4-100-h-battery-cells/7238704366.html

Cool, thanks, being unsure figured I'd ask. Spot on about just buying from an actual company over CL.

So I have a conversion van that I've gutted to convert. The house battery I'd planned on mounting in the alcove above the front seats as it's a nice out of the way spot. Then I got to thinking it may get too hot up there in the summer so I was thinking about mounting them in the back behind the...

Some good stuff here for a guy planning his build with CPAP in mind. This is the 12v cord I found for my ResMed: https://smile.amazon.com/dp/B07P6H994Q/?coliid=I3USAYZQC4TR7J&colid=1ODC36DNV3D23&psc=1&ref_=lv_ov_lig_dp_it

I'm planning on travelling around a bit trying to travel with the weather, southerly in the winter and northerly in the summer in hopes of avoiding lengthy extreme heat or cold. So I wouldn't expect below 32 nights frequently, but in warmer weather in the alcove in direct sunlight I'd imagine...

So after reading through the entire thread, here's my take on the gist: Unit limits current from one input if any current is sensed from the other input Can drain starter battery if house battery is low LFP float voltage is high, adjustable w/BlueTooth module There were some other things...

Just curious if anyone is using an RPi or Arduino in their solar setups, either for the DIY factor, or in place of a not readily available product. First time dabbler, just curious to see real world practical use applications.
