Greetings all,
I have a 20kW Panel system into a Paralleled pair of Sol-Ark 15kW
with 5) 48v x 100a ReBel batteries. (2mos old)
I need another 200a of battery and ReBel are not available.
I am kinda BMS ignorant and have been reading up.
I wanted to add 2) of another brand but have been told...
It has taken Aric 2 weeks to respond and he has said they have no more in stock and no more on order.
I know this is the BMS because of a failed Switch.
I am not sure of the battery chemistry. yes, all bussbar connected. w/ 100a protection for each battery
I think today project will be to dissect the one already opened up for cell identification
5x 48v / 100a to bussbar (Paralleling the bank) out to both Sol-Ark inverters as per their diagrams.
Please explain? The Rebel batteries have only BT connection, no communication to inverter
I wanted to just drop 2) EG4's into the system but was told they are not compatible?

There is 15' of 2/0 wire between the Inverters and the Buss Bar.
Before I added the 4th EG4, All batteries were connected to the buss bar with 36" 4 ga wire and i had observed this same issue.
I have since bought the 4th and installed the 4 and Rebel #1 into the Signature Solar EG4 Rack. This...
Lead Acid was chosen on the Sol-Ark as none of the BMS's go to it. I would LOVE to come up with some way that all the batteries could talk to the SA and be properly managed.
The Sol-Ark Settings are;
Battery Capacity(0-9999Ah) - 900
Max A Charge(0~275A) - 112
Max A Discharge(0~275A) - 275

Failing JBD SP25S003C 48V 100AH BMS
Communicating via BT with one of my BMS’s has gone wonky.
It continues to ask for password but does not seem to recognize it, but then will show some info but something in the communication side is braking down.
I have tried the Xiao app and the Overkill. It...
Batteries:
When the batteries arrived from ReBel they would not work.
The BMS Settings were all wrong and needed to be adjusted.
The EG4's are as is.
The ReBel batteries have the JBD-48V-100A-BMS-SP25S003 BMS
OverV - 3.7
OVR - 3.35
OVRD - 2.0s
UnderV - 2.5
UVR - 2.875
URD - 2s
PackOV - 58.4...
All wire lengths were the same. I have even tried doubling the length on those batteries that were reacting faster and made no change.
I have manually adjusted all of the voltage setting in the Sol-Ark and that part has been fine
Battery Bank Charging
I have 9 Battery 48v – 100a Lion Bank.
This is a mixed breed and I am wondering the best way to manage charging?
5 of these batteries are from ReBel Battery in Lake Jackson TX who is out of business.
4 of these batteries are EG4 Life Power4
The dates in service is also...
I support your experiment... PPE ... :-)
What else can one do with old expired Lead Acid Batteries besides send to recycle?
I have a LiOn bank, but also have a pallet of dead Lead acid ?
Greetings All,
I would like to augment my solar system with some wind generation.
I am in a residential area that has a POA so discretion is a must..
Thoughts? Ideas?
Thanks
Drew
