  1. Thank-you zivva. I finally had a chance to try this. Unfortunately it did not work. I am starting to think that the BMS software is not the same or incompatible between each battery and between the batteries and inverter. The one battery is around a year older than the other, so there might be different software. I make that statement because: If I set the Deye to Lithium 16, I see the older battery, configured as Pack 2 which shows on line 2 of the inverter. If I set the Deye to Lithium 9, I see the newer battery, configured as Pack 1 with a temperature of 331 Celsius. It shows on the first line of the inverter. Once I set Lithium 9, after around 15 seconds I get a fault status 020 on the battery line. I also get a F51 fault on the inverter main screen so that tells me the inverter sees the battery but because of the setting it cannot decode the messages.
  2. Yes, I have the same cable. My dip switches the same. I can put the inverter cable into either battery, it still registers the same battery on slot 1.
  3. Good morning, yes. Battery A is older than battery B. My scenarios: Battery A : 0001 (Pack 1 Dip: 100000 Inverter connected) Battery B: 0010 (Pack 2 Dip: 010000) The inverter sees Battery A and it sits on line 1 of the BMS screen on the inverter Battery A: 0010 (Pack 2 Dip: 010000) Battery B : 0001 (Pack 1 Dip: 100000 Inverter connected) The inverter sees Battery A and it sits on line 2 of the BMS screen on the inverter Strangely, if I connect each battery separately, the inverter sees each battery. I do not have a terminator on the last battery but have the open RS485 port on the battery connected to a Raspberry PI via RS485 -> USB.
  4. I quickly tried it, it still shows 1 battery, but it moves the battery to the 2nd line on the BMS tab of the inverter. Edit: When I swopped the cable from the inverter and used the opposite batteries with those dip switches, I see 1 battery on line 1. Interestingly, I could change the position of the battery on the fly, so when I changed the dip switch, the battery automatically changed positions without restarting.
  5. Good morning. Firstly, thank-you for the wealth of knowledge shared on this thread, I just thought I would share my experience. I have 2 Narada Batteries, I can confirm the Deye inverter sees one battery at a time if I use a cable pin-out: Inverter 1 - 3 Battery Inverter 2 - 2 Battery I then have a RS485 cable connecting the 2 batteries The pins on each side match in numbers (according to my cable tester), ie. 1 - 1, 2 - 2, etc. The inverter lithium mode is set to 16. I did try multiple dip settings and hope to get the second battery visible to the inverter in the near future, but if the batteries are communicating then I am not so sure there is cause for concern. The batteries are now set to 0000 and 0001. It looks like the inverter SOC displays the BMS SOC value of the connected battery. Seeing as I lost my RS485 port on the Deye for the battery connection, I grab stats from the wifi. I set the Deye wifi dongle up to have a static IP (either on the DHCP server or on the wifi dongle itself). I then use https://github.com/jlopez77/DeyeInverter to grab the stats and publish the stats to MQTT. When I want to modify work modes or inverter setup, I connect using PowerMan, go to apps and then use local mode. Its not a great interface, but it does work.
  6. For anyone else that may have the same issue as I had with the battery switching off, I finally figured out that my logic was incorrect, I worked out the Amperes using 230V/240V instead of using the batteries 48V so the Amperes I was pulling were too high and the battery switched off to protect itself. Adding a second battery should solve the issue I have been told by the suppliers of Narada batteries.
  7. Hi. I have a Narada 48NPFC100 connected up to a 5kVA Voltronic inverter (Skyking) and have a bit of what another user wrote, buyers remorse. First issue: The inverter is connected to a raspberry PI and I read all the stats I require from the inverter, but the inverter has no idea what the battery is up to and reports very dodgy statistics on the battery current as I have read on this forum. The battery is connected to the same raspberry PI using a RS485 TTL adapter and I figured out that the slave id of the battery is (38), but cannot read any of the registers from there. A Narada technician was kind enough to check the battery for me, he opened a program named BMS on windows and it automatically picked up the battery and could read everything from SOC to number of cycles. Of course, I could not get a copy of the program, but it does mean there is a way to read the information from the battery. Second issue: Sometimes the battery just suddenly turns off all current (on full charge), I think it is trying to protect itself from fast discharge but my stats on the inverter does not show high discharge. The inverter has to quickly switch to a different source of energy and there is a noticeable power dip. I physically have to restart the battery to get it to work again but I think this is definitely bad for the inverter and for the appliances connected to the inverter. Any help would be greatly appreciated.
  8. Hi Tia I am currently running this in my home assistant with my Voltronic based inverter that is hooked up to a Rapsberry PI, it might help you with your requirement: https://github.com/ned-kelly/docker-voltronic-homeassistant Have a great day
  9. Hi My name is Mark and I am in the Valhalla, Centurion area. I currently have an Axpert 3kVA Plus 24v Inverter with 2 Deltec 100ah lead crystal batteries used as a UPS which I bought years ago. This has served me well in the past to bypass the blackouts. i was wondering what the best configuration of solar panels would be to make the best of the MPPT with as little panels as possible (1500W with an open circuit voltage of 145VDC). As far as I understand, 4x 365W Canadian Solar panels in 2 strings would give me 1460W which would keep the open voltage down to 94.4VDC. Thank-you Mark
