I may need to replace some or all of my fortune lifepo4 cells. Does anyone in the San Francisco Bay area have any for sale? Thanks

I need to run some 2 awg cable from my starter battery back to my DC-DC charger. Now the issue of course is cost, as there is about a 25 foot run for both cables. I was going to get some cable on Amazon that said it was oil resistant, but after scanning through the listing I found that the...

Long story short I made a rookie mistake and completed a short circuit on 4 of my cells. I was preparing these cells for pre-charging before top balancing. They hadn’t been used since I unboxed them. I added a bus bar where it was not meant to be and sparked aggressively. I couldn’t figure a...

I'm thinking about checking out this panels for my van: https://sfbay.craigslist.org/eby/mat/d/sacramento-overstock-solar-panels-for/7210644376.html I would be using two, but they are polycrystalline and it seems like the recommendation everywhere is to go with mono. Does it really matter at...

Ive searched around on the forum and couldn't the answer I'm looking for. I am building a 24v LifePo4 system and need to decide on a ac/dc distribution. This is a nice unit all-in-one panel Explorist.Life uses, but in the questions on Amazon is says it can't be used on 24v systems. Do you know...

I'd like to use something like this on my van as I am very limited on roof space and would only be able to fit one of these. My system will be 24v 400ah LiFeP04, Victron Multiplus 3000w, I still don't know what size MPPT I will need though. I apologize for my lack of solar knowledge, still...

I am deciding between sticking with a 12v Renogy 3000w inverter I already ordered or getting the Victron Multiplus 3000w 24v. The Multiplus is $1,027 at Inverter supply right now which is why I am tempted to bite the bullet and go with that option. If there are any other 24v 3000w inverters you...

Thinking about getting this victron multiplus 3000w from this site. I like the price, but it makes me skeptical. Does anyone have experience with this site? Thanks...

I am finally ready to start ordering some electrical components for my van build. I have been a little hesitant to pull the trigger so far. I have decided to stick with Victron equipment as it fits my budget now and want quality products in my van for when it comes time to sell it. I just need...

Hey I've been reviewing a bunch of different brands of inverters. I was originally thinking of using the Victron Multiplus 3000 for my van build, but decided to just get a stand alone inverter and save a few bucks. I've checked out AIMS, Samlex Victron, Eastwood, Renogy, etc. Anyone here using...

I have been working diligently to understand how to build my own off-grid electrical system for my up and coming sprinter van. Fellow member @FilterGuy has been extremely helpful and generously put together three separate diagrams, attached below, for a potential setup. So far the plan is 400aH...

I put together a spreadsheet of solar system parts mainly based off faroutride.com 400w/200aH system which is the size system I believe will suite my needs and then swapped a few items like the Renogy panels,inverter, charge controller, etc. I want to do a quality build once and do it right...

Up until now I have been looking to Renogy for a lot my van build parts, but now I am starting to think otherwise and go with Victron for my charge controller and inverter. For solar panels though would you not recommend Renogy? I found this site, here is a panel for example...

Hello, I am getting a 2006 dodge sprinter 2500 in about a week or so. My plan is to live full time in the van and be able to power my whole system from solar and while driving. I have spent 4 full days researching this and plugging in numbers to various calculators, but still need some help...
