Awesome thank you I'm still looking at a couple of weeks before this charge controller gets here so as not to waste your time I think I better wait till I get it here thank you
Great information Frank. What is the maximum voltage per cell with your lithium Chemistry? Mine is 4.2 per cell but I only charge to 4.05 per cell. Which BMS are you using? It looks very nice. Snow here the next couple days.
So I'm very interested to convert to lithium batteries but outback said I'd have to go with A G M cause my outback inverter with flex max 60 wouldn't charge lithium?? Now I see your video and why would outback tell me this to try to sell me AGM??
It will charge just fine but will not communicate with the bms in the battery. Lithium Iron Phosphate is the most suitable voltage wise. They said to be safer the other lithium chemistries.. There is a few downsides to lithium as well. Just depends on your application. Cheers
I've done a grid tie solar arrangement on the house but I'm wanting to do off grid somewhere else I've got tesla battery and solar panels wind turbine 6000 W inverter and an outback charge controller on the way but not real sure on how to program that outback charge controller for the Tesla battery
Yes I'm working on the battery balancing system I have the first part here then I've got to order another part shipped from I believe it was Ukraine 40 bucks or something like that
Tesla battery is kind of an odd battery a lot of guys are using them and their solar arrangements I am just setting up a system and trying to learn all I can
Most of the tesla packs use lithium cobalt mix. I believe. The max charge 1 cell group can handle is 4.2 vdc per. You also need to know the series connection of the pack. Ex. 6s 7s. Some are different. Most people charge them to 4.1 v per cell group to be safe. You multiply 4.1v x the number of sereised groups in the pack. 4.1 x 6 = 24.6vdc. If this is the case then set the controller to 24.6v for your absorb. Ive been told not to hold that voltage but cut the current when the set voltage is reached. Thats a full charge. Hope this helps. Cheers
If you wanna talk to a guy with that setup and is very nice to talk to ill give you a link to his channel. I would say his setup is very well put together
I know this is old but this really helped me out thank you
@@markjohnson4486 glad to help
Thank you, swapping my old lead system for lithium this weekend and this is just what I wanted to know.
Nice don't forget to set the temperature compensation to zero as it overides the maximum voltage.
Good to know I’ve got a flexmax I’m going to put on my Tesla’s come spring , thanks for the info sir
Awesome thank you I'm still looking at a couple of weeks before this charge controller gets here so as not to waste your time I think I better wait till I get it here thank you
what's the different if i set the AUX on ON or Auto mode or OFF?? please answer, thank you
there is a aux port that can be used. unless you are using that port it doesnt matter if it is on,off or auto. Thanks for watching
Thanks again that will certainly help
Excellent video...
Wonderful.
Thats alot of cells,,crazy amount maken power !
Yeah that would be awesome

My cells are LiFePo4. Max charge 3.6v and i go to about 3.525v. This chemistry is more similar to lead acid. But with incredible power
It is a china bms.
@@frankz1125 Thanks you, stay warm my friend.

Do you have the math for 24 V system sorry I hate to ask
What cell are you using?
I like to help but i dont like to be taken advantage of. All questions are welcome. Except 1. The address of my battery spot.

In my opinion the chemistry you have there in those packs is the best but make sure you use a bms with cell level cut off. It is a flammable battery.
You seem to really know what's going on so I thought I would ask you I hope I'm not inconvenience you in anyway
I try but im not a battery expert. You are welcome to ask.
I am using a six sale tesla battery
4.1v x 6 s= 24.6v
Your chargue controllers is not outback flexmax is chinese copy
I have one of each. Both fm 60s. Would it be good to see them in a comparison test?
