Hey All.
I have (4) 12v 300ah Enjoybot brand batteries hooked up in series to power a 48v Victron system. I’m trying to understand what are the optimum charge settings for the battery, and although the manufacturer was quick to respond with specs when I emailed them, some of the numbers seem...
If I understand correctly, are you saying your inverter still draws enough current to create sparks on detaching even with your inverter turned off?
I do not have a switch or breaker on the DC side of my inverters. (Although I do have a fuse) The inverters do have an on/off switch on the case...
I am in the process of creating plans for a large scale RV solar installation. It will be a 48V system, and with that comes some caveats of having the added difficulty of finding 48V nominal rated components. For example, at first I had planned on using simple Blue Sea Systems 6006 battery...
Hey All,
I'm in the process of creating my solar plan for a large RV. I'm wondering if it is ok for a 120v neutral line that is upstream of the MultiPlus, to share the same neutral bus as a 120v neutral line that is downstream of the MultiPlus. See the wiring diagram picture for more context...
For the batteries I purchase from Enjoybot, they are rated from the manufacturer for 5000 cycles at 80% depth of discharge. Additionally, after these 5000 cycles rated by the manufacturer, the batteries will still remain very usable for a number of years, just with a slightly reduced capacity...
A question of newbie curiousity, how does the BMS actually cut power in event of a BMS shutdown event? I’m specifically thinking of BattleBorn, LiTime, Enjoybot LiFePo4 batteries that don’t have a mechanical circuit breaker on battery case itself.
Since these batteries are rated up to 200A...
Thanks for that info! I agree with all your points and from my research, Enjoybot is quite similar to LiTime and I’m hoping to see the same level of longevity and support with them as well.
Thanks for the link. Yes good idea on not maxing out the current draw on the batteries, I’m planning with oversizing my inverters and batteries to have a good amount of safety margin. Except in extreme situations, I really only foresee my max continuous wattage draw in the realm of 5000w.
I’ve been considering also getting the victron battery balancer system if I do run into problems keeping them in balance. In addition I’m planning to pull all the batteries out and charge them up on the bench individually with 12v charger as a sort of “balance maintenance”
Edit: to add that I...
Ok, glad to hear that will have a max continuous current of 9600 (or slightly higher with nominal voltage). I’m curious to read about what issues are arising with batteries in series. I’ve done a bit of searching already, but if you could link me to any specific threads that would be appreciated!
Hey All,
So I’ve just recently purchased and received 4 12v 300ah enjoybot LiFePo4 batteries (with the new low temp cut off added) for a large RV solar system. I plan on connecting them in series to make 48v, and will hook them up to 2 multiplus II 48/3000/35 inverters.
The thing that’s kind...
Thanks for that insight on the class T fuse! I’ll look into that. Unfortunately looks like the class T is hard to find and/or very expensive right now…
Great point on the diagonal battery connections. I’ll update that now!
The batteries shown do have breakers already, so thinking that will eliminate the need for a downstream switch.
Regarding the batteries class T fuse… I posted this in a DIY Solar Facebook group as well, and they had...
My rv is essentially a small home, ha. It is a 41 foot grand design momentum fifth wheel with 50amp power, and we will be full timing in it, so trying to size my power to match that.
I hope to be able to run the A/C for a few hours on really hot days, while still powering all of our daily use...
