Jeff, Very helpful! Thank you for taking the time to do this. Too bad you couldn't use an under mounted AC / Heat pump setup, some van owners use or even a mini-split with the outside unit under the truck, as well. All the Best, Tony
Thanks for the review. I charge my AC2a, AC50b, AC70 and AC180 while driving. I also use it for charging my Ecoflow River 2 Pro. I use my AC200l and B210 battery for power down only and do not charge in my car due to the weight. I had my Charger 1 installed at a local professional audio shop. And they installed a 60w fuse close to the battery to prevent a disaster from happening in the car BEFORE the breaker in the back. Bluetti needs to put a fuse forward and not rely on the rear breaker (POOR DESIGN).
It's nice they had a Charger 1 to give to you but I ordered one about 6 weeks ago and am still waiting for it. I wish that when they start promoting it they have enough in stock to handle orders.
hi, I enjoyed your video very much, very informative. Could using a 300w pure sine inverter have the same results as Bluetti charger 1. The 300w pure sine inverter is so much cheaper.
If your roof-mounted solar array has a higher voltage than the DC charger you can parallel them with blocker diodes. 2 or 3 phase rectifier assemblies are an economical way to get an array of power diodes with 0.5-0.7V forward drop and 1000-1500V reverse blocking voltage, built in heatsink, and mounting tabs You probably only need one for your DC charger as solar panels already have them (what enables them to be paralleled in the first place). If the MPPT controller does not get "lost" you should be able to use as much solar as possible until the solar voltage is pulled down to the level of the DC charger. I am painfully aware that MPPT controllers can get "lost". Some, but apparently not all, of the original AC200 (not 200P) units had a charge controller that would get lost charging on batteries and slowly walk the charging current down so a trickle over about 5 min. Allegedly they have gotten better to allow more flexible charging options.
Yes, a diode would work, but then it would be "either/or" where charging would happen from whatever source has a higher voltage. If the alternator charger is 500 watts and the panels are 100 watts then you would charge at 1/5th the speed when going from panels. It wouldn't be using both at the same time.
@WaveformScience If my 915W ~90V solar array on my camper sags from cloud or shade at some point the DC charger could contribute as well. I don't see why it would have to be binary.
This is outstanding! I wasn’t aware of the need to draw off the starter battery instead of the auxiliary battery. Thank you
Thanks for all the info. How does one go about determining the "generating capacity" of our vehicle (@16:40)?
Thx for making this, very handy for my two build outs.

thanks :) great U have some fun while doing all those tests and builds :D and U willing to share it with others. cheers

I agree, and called this out specifically in the parts section

Thank you, invaluable information. Well done!!
Etaker works with solar as it has a dc input for solar

I have a 240A alternator 119A idle, upgraded from a stock 110A. Any thoughts on paralleling 2 charger 1's to an AC200L?
