This will work perfectly fine. The amount of time it takes to balance depends on your BMS. Does it have an active or passive balance on it? 1A or 2A balancing? Hopefully you didn’t go with a seplos BMS…

Yeah the whole conversion documentation on their blog and blog is amazing! Highly recommend giving them a like comment and subscribe :)

@BradCagle has used Sun fun kits and liciti to put raw cells and BMS in a box.

Or even better this one! It’s an RV application so closer to yours. Web page blog: https://www.google.com/amp/www.beginningfromthismorning.com/dc-power-part-1/amp/ Video:

Here buddy, 48v to 12v to 5v if you want to power any 5v devices like usb phone chargers or in this case a WiFi modem :)

Damn. That sounds like it’ll do the job! Also sounds like a bitch to set up but totally worth it if you’ve got the time and inclination! Good luck buddy!

How much do you want to spend? How simple or complex do you want the system to be? Here’s a possible quick solution for under $10k: 1. Get 10 of these used 435w panels santan solar for ~$1k 2. Buy a Delta Pro Ultra Intelligent kit bundle for ~$7.5k 3. Wire it all up and you’re good to go...

Smartpanel 2 is easier but way more expensive. If you or someone you know is good workin g with electrical this video will save you thousands of $!

Great spreadsheet! One 48v 100ah LiFePo4 battery is 5kw. A 1500w 12v to 48v charger can do that in 3.5 hrs. Add in some solar and you’ll never need to worry about energy.

I’d say you fixed it not “resolved itself” lol your Victron equipment is most likely set for Lithium charge parameters so you should be good! Glad it’s working!

Yeah, what those guys said! Basically PV watts will tell you that you get x amount of avg. sunlight per day in your area. Let’s pretend you get 5 hours of sunlight per day (highly unlikely but it’s a nice even number ;) Then it’ll ask you how much kw you want to produce. Sounds like you want...

Your math seems to check out. If you’re really concerned about fires it’s the wiring that you need to oversize and stay with 10 panels on your high voltage string and you should be set. You need to do a precise or nearly precise calculation of the length from your solar panels to your DPU...

This could have damaged your batteries. Many solar charge controllers SCC are preset to lead acid batteries which is probably why it worked well for those when you had them. Best case scenario is your scc tried to bulk charge and equalize your LiFePo4 batteries and caused them to shut themselves...

K490 is absolutely right, you definitely should take the time to figure this all out properly. That being said I’m fairly certain that you could get through the night with a system like this :) and if it turns out that you can’t make it through the night with 30kwh of storage just add more...

Yes, as long as the BMS supports it. Might need to look into a kit to make it easier to move back and forth. @BradCagle did a video on this kit that might work for your application
