October 12, 20223 yr Hi I've got an Ultra Energy 4.8kWh battery connected via can bus to the Luxpower. It's reporting the capacity and SOC correctly but the battery voltage shows 5.0V instead of 50.20V. It seems that the inverter is calculating the reported voltage wrongly (decimal value) or the battery is sending the wrong data. Any advice?
October 20, 20223 yr Author Solved it. For those who are wondering. 1. The Ultra Energy 4.8kWh batteries dated from this year, they are using an AIENEGY BMS which is a clone of the Seplos BMS. The BMS monitoring software I can provide upon request the Seplos monitoring software does not work. 2. To communicate with the Luxpower SNA5000 the BMS need to be set to WOW RS485 protocol in the monitoring software 3. The Luxpower needs to be set on brand 21 4. Cable is standard RS485 pin 1 to pin 1 and pin 2 to pin 2, NOTHING else connected. CANBUS port on the battery side and CANBUS/RS485 on the Luxpower side. 5. All dip switches to off Works perfectly
December 19, 20223 yr Great stuff!! I have an N Energy battery, how can I access the BMS and check what protocol it is using?

Coincidentally lighting struck my Ultra Energy and the only battery in stock was the N Energy. It uses the exact same BMS. You can access the BMS with software that I can provide and with a RS485 to USB converter.
December 22, 20223 yr Excellent! I will pm for the software and hardware. Do you know where N Energy is manufactured or where to get local support for the battery?

Are you able to share screenshot of your connection and settings so I can ensure that I didn't miss anything? Also when you saw WOW RS485.... I don't follow. I don't see anything like that on the battery nor inverter. See my connections

Hi @RiaanC, did you ever manage to get your system to communicate as suggested by @Neurik? I need help with communication on mine.
May 6, 20233 yr Author If anyone needs the software PM me your email address so I can send it to you, I can't attach it here because it's larger than 3MB. Also watch out for the N Energy batteries. I returned mine cause the batteries inside were 80 Ah instead of the advertised 100 Ah and one of the cells were leaking! Whereas the Ultra Energy cells were actually 120 Ah. I replaced the damaged BMS in the Ultra Energy with a JK BMS and linked it with Home Assistant. No issues at all. Edited May 6, 20233 yr by Neurik

I'm just trying to connect my N-Energy battery via the comms cable and not in "Lead-Acid" mode. Any guidance here would be highly appreciated, including the comms cable wiring.

July 5, 20232 yr I have not gotten any feedback from the guys that got the communication working. Happens a lot on this forum unfortunately. People ask their questions get an answer or not then disappear, never to be heard from again I guess.

People only there to serve there own needs, once they find the answer there is no consideration for the greater good of sharing information. Same thing you will find in opensource software
July 5, 20232 yr @iiznh I hear what you are saying. But on the other hand I know they don't owe me anything. It just makes me sad reading the answer is right in front of me but I cant get it. haha

Looking at the thread, the BMS is a copy of the Seplos... which is fairly well supported w.r.t software, plenty code around to read the values Maybe look at this project and also the references listed https://github.com/syssi/esphome-seplos-bms Edited July 5, 20232 yr by iiznh
July 5, 20232 yr @iiznh Thank you for sharing that project! Honestly appreciated. My next step was to just get a Victron smart shunt for SOC, but lets see if I can get the software working. I owe you beer! 🍻

July 6, 20232 yr Author Apologies to anyone waiting on me for the software. I've shared it via Google Drive you can download it with the following link. https://drive.google.com/file/d/1cnqzpXq4m2gC6LMKKvU9qAjEyEIuCm71/view?usp=sharing You will need the following https://www.robotics.org.za/RS485-MINI?search=basic usb to rs485 converter%2C 2 wire I can't recall exactly but you connect the usb to rs485 to the battery via the RS485 port pins 4 and 5. Open the software and select the com port that the converter was assigned and connect. If it doesn't work swap the wire polarity on the converter. Once connected go to the item on the side where the protocol can be changed (can't recall what this is called as well it's been a while). Change the protocol to WOW RS485. Connect the battery to the Luxpower on the CANBUS port with pins 1 and 2 straight and choose battery brand 21. Make sure all dip switches are off. Note that I have since swapped the battery type to lead acid and set a float voltage of 50 and charge voltage of 53. The way these BMSs talk to the inverter causes micro charging / discharging which isn't good for the battery (subjective).
July 6, 20232 yr @Neurik Where on earth did you find this software??? IT WORKED!!! I tried the battery monitor from Seplos but that did not work. I cant modify any of the parameters. Like you mentioned with regards to the communication protocals. I see there is a password field, do you know what it is?
July 6, 20232 yr Author Sorry forgot to mention the password for the software to modify anything is 0000
