Hi all

I have a SVolt 5.4kWh 106AH Lithium Ion Battery connected to RCT Hybrid RCT-INF V4 5.6K-48V inverter off- grid.

It was working 100% until I tried to connect the battery communication cable to the Inverter.

I set the inverter Battery setting to Pylon (they say the SVOLT work on Pylon settings) and connected the cable that came with the SVOLT Battery.

The screen went dead. Battery still functioning 100%, charging, and powering the inverter/load.

When restarting the system by switching the battery off, the screen come back up, but as soon as inverter's relay's kick in, the screen dies. I also removed the COM cable completely for now and set the inverter's battery setting back to USER as it was working perfectly fine before.

I figured that when switching off the PV breakers, leaving the PV breakers off and then restarting the battery, it works, the screen stay on. The moment I switch the PV breakers back on, the BMS screen on the battery goes dead again.



Everything work 100%. Charging very well from solar panels, and no issues running the load.



To me it feels like things went wrong the moment I tried to connect the COM cable and set the inverter's battery option to Pylon. I just have no idea why is it not working when PV is connected and is perfectly fine when PV breakers are off.


Anybody else on this forum had a similar experience ?

Your comments will be much appreciated.
