w0ss said:20mv at 3.85V though. Isn't that when the cells have a flatter discharge curve?
Does anyone knows the pinout for the CAN bus at the RJ connector of LG Chem battery module ? It´s a EM048063P3S5.
I´m unable to communicate with a SMA Sunny Island.
Thanks a lot.
Hi Matthew.Did you manage to find this?
I have a SolaX X1 Hybrid (SK-SU5000E) that came with a "branded" SolaX battery cabinet that under the hood is actually an LG Chem em048063p3s4 battery
I can get you the pinout of the BMS cable to the cabinet but it also has a "converter" from RJ48 to RJ50 which has an RJ50 plug going to the battery itself it it helps - I would also like to make up a single cable and drop the "converter"
I have a slightly different issue in that I now have two of these batterires and want to add them into a single stack but just do not seem to be able to get them to communicate with each other and think the intra-battery comms cable might be the cause and am looking for the pinouts for that cable if anyone knows or is it a simple straight through RJ48/RJ50 cable?
I can connect one battery at a time so the inverter is happy when only a single battery is connected to incoming DC with the BMS cable connected to the inverter in the top right CAN port
However when I then connect the bottom single port on the top battery to the top left port on the bottom battery they freak out at shutdown
From many installation guides I have read that you do the below:
- Connect the top right port to your inverter and the bottom single port to the next battery down on the top left port
My questions are:
1. What is the actual correct connection for multiple batterires for the inverter?
2. What is the pinout for the intra-battery cable?
3. Can I make up an RJ48 to RJ50 cable without the converter bit from the battery to Inverter?
Thanks in advance
Many thanksHi Matthew.
I´ve find out the pins for CAN-Bus and for internal bus.
For CAN-Bus to the inverter it´s pin6 (CAN_L) and pin8 (CAN_H).
For internal bus you have to cross pin 9+10.
With kind regards,
