Batteries after a firmware update from RX04 have been flawless
The problem I had with the RX04 firmware. Was when winter came and it was cold enough for the batteries to require heating to charge. They went into emergency stop unless the power was coming from the grid. The reason was that the solar in the morning if a cloud came by the PV input would drop below the current needed for the heaters on the 4 batteries. That would cause them to shut down.
RUiXU tech sent me TS24 that allows them to heat for 2 hours from stored energy in the battery's. It also solved a charging issue that TS23 firmware had of charging at max amps until hitting the cell/pack overvoltage protect limits. I also bought 2 more in Sept 2025 to max out the open ports on the RUiXU buss bars. so now I have 64kWh of batteries. I would buy them again. I got all of mine from Renewable Outdoors.com The shipping was from RUiXU in California. It took bout time about a week for them to ship. I'm assuming it was due to holding them to fill a truck heading my direction.
I purchased two of these and self installed them. My local AHJ has been...quite difficult to work with demanding documentation on top of documentation over and over. Ruixu support has been *stellar* in tracking down and providing every piece of documentation. Installation was very straight forward, but these are HEAVY batteries. So aside from the physical difficulty, which is no negative but something you do need to be prepared for, installation was a breeze. Getting them setup as a pair was pretty straightforward. I will say, getting the EPO (emergency power off) functionality working is kinda wonky (requires some secret touch screen shenanigans), but once enabled works great.
I combined these and paired them with a dual SolArk 15k setup and had zero issues getting them to talk together. They're happily humming along for the last month or two with no issues. I was even able to lookup their modbus info and get custom monitoring setup on them with basically no hassle and an ESP32 pushing data into HomeAssistant
I have used the Ruixu Lithi 16 for about a month and have had no issues. Plugged it into my Ruixu Sunon 12 and it worked and communicated easily. Hardest part was getting it onto the wall mount as it took 4 of us to do. Was also impressed with the shipping box Ruixu used to ship it, was wood and very sturdy.
