BasalGanglia

All Solved. The Solar Installers rang me, got me to connect to the Inverter on my phone then did something at their end. All up and running now. Thanks everyone for the info.

The problem is after switching on the inverter with everything connected it now asks if I want to add a battery. So not sure if the settings have been reset and its just a question of re-entering? I did not want to do anything else without expert advice. Also after leaving the batteries balacing overnight I was expecting the SOC charge lights to be lit and all the same level but non where lit. Instead just the LED light on the RUN light was flashing, alternating between each of the three batteries. Does this mean they all balanced succesfully? All the online videos I could find for these Pylontech only show you pressing the SW button with the lights flashing. Yeah not sure why the installers used the rs485 port instead of the CAN. Would pressing the SW Switch again on the master but this time with the inverter cables connected and switch on, perhaps tell the inverter that the batteries are there?

My pictures are very dark but yeah I have set it up the same when I reconnected everything. Only difference is I connected the grey data cable from the inverter into the rs485 socket rather thann the A/Can socket as you have done. I did this as that's the way the installers had it.

When you say BMS cable are you refering to the black cables that go from Link 1 to Link 0 etc. The grey cable in the two battery picture is from the Inveter to the rs485 port. (On online videos they seem to use the A/Can port instead but this is the way the installers did it). On the picture with the three batteries I have disconnected this grey cable from the inverter and also the Positive and Negative power cables from the inverter. This is what I did before pressing the SW switch on the Master battery in order to start the 'Balancing'. But after reconnecting and switchinng everything back on the inverter asked if I wanted to add a battery.

My pictures are really bad due to the poor lighting. I have Link Port 0 on the Master empty. Then I have Link Port 1 from the Master connected to Link Port 0 on the Slave. Then Link Port 1 on that Slave to Link Port 0 on the last battery. This is how the installers set it up with the two batteries. So I had it in the same way when adding the third battery, leaving Link Port 0 empty on the Master. Is this incorrect?

Here is very short video of the batteries balacing after I pressed the SW run button on the master battery VID_20230307_182928 - Cut.mkv

Here is a picture of the third battery added with the positive and negative cables from the inverter disconnected and also the data cable disconnected. The inverter and isolator switches also turned off. At this point I turned on the each battery starting from the Master to the last battery and then pressed the SW Run button on the Master

Here is another picture of the setup before the third battery was added

Thiis is a pictures of the setup before adding the extra battery

I recently had a hybrid solar system installed with a LuxPower hybrid inverter and two us3000c Pylontech batteries. The system worked perfectly and decided to purchase and add another us3000c Pylontech battery of exactly the same spec. So I started by switching off the Isolator switch and also the switch on the inverter and disconnecting everything. I then put the new battery in the top of the stack to make it the Master. Connected the batteries in Parallel but left the power cables from the inverter and data cable unconnected. So I had previously waited for the current two batteries to be fully charged. I then turned the batteries on in order from the Master to the last battery. The batteries have an LED light which has 'RUN' underneath and a set of six light with an triangle underneath to indicate state of charge. All six state of charge lights where full lit on the current batteries. I then pressed the SW Run button on the new Master battery. This new battery had two LED lights lit on the state of charge. On the two current batteries each LED light on the RUN started to flash and on the new battery the RUN Led light was fully lit. So seems like it had started the balancing successfully. I left it running over night. In the morning all the lights were out except the RUN led light on each battery including the new master battery was flashing, alternating between each of three batteries. I then turned the batteries back off, reconnected everything. The positive power inverter cable to the Master's other positive connection and the negative inverter to the last battery on the negative connection. I then connected the data cable from the inverter to the rs485. (The battery also had an option for CAN, which online videos seem to use. But since the inverter was originally connected to the rs485 port by the installers I added it back to the same one). After switching everything on the battery LED lights remain unlit and the inverter asks 'Add a battery?'. So my question is should I try to enter the settings on the inverter again or maybe try pressing the SW Run button on the master again with everything including the inverter connected. Or should I try the CAN connection instead of the rs485? I didn't want to try anything else until I got some expert advice. thanks in advance James
