Hi Everyone!
I just joined the forum and I am relatively new to solar so I thought I’d jump into the deep end right away and build a DIY LiFePO4 System for the Camper Conversion of a Mercedes 814DA that I purchased recently.
Just to give a bit of reference, the van is the older, big brother of the sprinter van with a GVWR of 16,500 lbs and the electrical system in the van itself is 24v.
I’d love to get everyone’s feedback of my thoughts so far so that, hopefully you can steer me in the right direction.
I am considering 8-12 200Ah cells that I would assemble, balance and configure into my own DIY power bank.. Judging from Will’s LiFePO4 DIY video, 8 cells seems to be the max before you have to start configuring things a bit differently. If I decide on 10 cells, would you then arrange the system in two sets of 5 that then join together at some point? What would be the best way to configure a 10 cell LiFePO4 power bank?
There will be 1-2 fans and an AC installed on the roof but the roof is pretty big so there should still be room for 1000 - 1200w worth of solar, roughly guessing.
I definitely want the ability to also power the LiFePO4 power bank with the vehicles 24v alternator. If that means replacing the stock alternator with a marine alternator I’m ok with that or if there is room I would install a second marine alternator that is dedicated to the power bank.
The vans electrical system will remain 24v so I thought that for simplicity’s sake to also have the solar system be 24v with a step down to 12v for certain accessories like phone chargers.
Any tips, advice or thoughts on where I am headed so far? Any recommendations for how to configure this system, what 200Ah cells to get, etc?
Thanks!
