My batteries consist of 16 eve 280ah cells and I have 2 packs. (32 cells total) I suppose it would be best to leave the switch on “all”. I had the switch mainly using it as a shutoff.
I went ahead and wired the switch to my positive side which I realize is standard protocol.
Guys,
I have 2 battery banks and it seems bank 1 is out of balance that I top balanced initially.
What do you think?
Also what do you suggest my BmS settings be at, I would like to cap charging at 80-85%.
From what I’ve read they say not to balance until 3.4v?
It seems my settings got goofy on...
Would it be ok to wire this switch on the ground side so I can use a shunt to monitor each battery separately? Attached is a drawing on what I was thinking. Or would there be a better way?
Thanks
Hello I was wondering if this would work...
I currently have a Mpp 5048 48 volt charge controller in a small solar shed. At the time I only have room to mount the 4 - Renolgy 100watt panels i currently have and was planning on buying 2 Trina 310 watt panels.
Charge controller will handle 145voc...
I now have that toggled off and lowered to 3.45.
Problem now is battery gets fully charged and triggers overload in bms.
My inverter is a Growatt 12000 Dvm-mpv. Is there a setting to fix this issue?
Currently I have bulk set at 56.4 and 54v float.
There must be a setting to tell the...
So I could probably sneak by getting 4 -320 watt panels and using the 4- 100 watt panels then for the time being? How would I wire them so it doesn’t put me over the open voltage?
Thanks!
Thanks gnubie for clarifying that.
Does my math look correct for fuse sizing below...?
My charge controller has 2 inputs, I was planning on putting the 4-100w panels to one input with a MC4 inline fuse
and I have 6-400watt panels I was going to wire 2S3P and breaker at a combiner box to the...
I just re-did the bus bars with some flat ones I didn’t have at the time when I started and now am getting more consistent readings.
Thanks for the help
Do my settings look correct...off Grid no utility power, currently have a 2000 watt Honda generator that I was going to tie into inverter.
48v 555 ah flooded battery bank, batteries are Deka auto batteries for now until I can get something better.
2800 watt of panels
I'm in the process of building mine now, I ordered it without the balancer, It came with a short red jumper wire, do I use that?
I see a b+ terminal on the bms where it goes but I don't see any mention in any youtube videos.
Some sort of directions or diagram would have been nice.
I just installed a chargeverter and currently have the negative going to the busbar where I have 2 battery packs connected. I would like my battery gauge to read this charge I’m putting back into the batteries. Question…can i hook the negative of the charger to the inverter negative at the...
Guys. I’m swapping out my Mpp 5048 for some more power, going from a 5kw to 12kw will I need to upgrade my battery bms and fuses?
I currently have 2 - 48v 280ah battery packs with the Jbd 200a BMS on each pack. 200a fuses protecing each battery and 2/0 battery cables.
What do I need to...
