I have installed the Orion Jr.2 BMS on my Lischen 272ah 16s pack. I'd like to use this thread to document my install for my off grid solar system and discussion with other users and potential users of the Jr.2 Since the Jr.2 is designed for electric vehicles I won't be using most of the options.
The Orion manuals are very detailed to the point I wish they had a manual for solar installs.
I purchased the BMS, the main wiring harness, the 200a hall effect current sensor and harness, and the Wifi Connect module and harness. Installation is pretty straight forward. There are 16 wires for the positive terminal of each cell and two negative tap wires that go on cell #1 and #9. I used the red M6 ring terminals and a ratcheting crimper I bought on Amazon. I highly recommend a ratcheting crimper, especially if you have any carpel tunnel onset.
The super expensive cell tap validator tool is absolutely not needed. It is very easy to check your cell tap connections using a paper clip and an alligator clip on your multimeter. Since the wires are clearly labeled I was tempted to skip the cell tap testing. I am very glad I didn't. Turns our I had the cells taps on cells 9 - 16 reversed. I might have fried my BMS if I connected it before I discovered my mistake.
The other connections are two power wires for the BMS and a ground wire. The Wifi module has a power wire and a ground. I found out that for stationary applications you only need to use the "Charge Power" wire to power the BMS.
I had trouble getting the Wifi module connected to my Wifi router until I used a paperclip in the "setup" hole. Once I did this it was very straight forward getting it connected and registered on their Cloud monitioring system.
I'm not impressed with the information available with Wifi module. It doesn't even show individual cell voltages. Just highest and lowest cell voltage. Sure that is all that is really needed but I expected more from such an expensive BMS. The Wifi module does not allow for any configuration, just monitoring. The Cloud based web interface is pretty dated and limited. I will probably return it if they will let me.
I have a Mini PC that I use to monitor my Schneider Conext equipment. I am going to move it close to the BMS so I can plug in the Serial to USB adapter and remotely monitor the BMS. I use TeamViewer for remote monitoring. This way I will have all the information available and full remote configuration.
I will have more information after I connect my batteries to my solar system. I am waiting on my buss bars. I will get some photos up soon.
