Hi all,
I'm writing this because i think i have tried all i can, and have currently no more idea's in things i can check, still i am unable to power on the system.
I have been using this guide for the Pylontech ESS and Battey settings :
https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom
The errors i have are :
- Breaker trips
- Low Battery Alarm
- Internal Failure Alarm
I have a Multiplus II 48/8000 with 4 Pylontech US5000 , The system is connected to 230Volt 25A Breaker, i'm only using AC-IN currently, the PV (Enphase) is AC Coupled and connected to the AC-IN
I have configured the Multiplus using (Remote) VE-Configre and loaded the ESS Assistant, which is set with settings from the above Pylontech page.
Power on failure
I have limited the AC-IN to 25A (Devicelist->Inverter-> Input Current Limit) and also set the max power to 5500W (Settings->ESS->Max Inverter Power) but when i poweron the Multiplus with the DC Batteries connected the breaker trips when the Multiplus goes to Charger mode, however it does start when the DC Batteries are not connected, but Low battery LED is on.
I have check the VEConfigure file multiple times and see no errors i may have made.
The GX (FW 3.40) detects the batteries als Pylontech with the settings shown, also the DVCC is enabled automatic, It reports the batteries as 48% SOC , 49.31V , -0.2A, -9W , Lowest Cell 3.282V Highest Cell 3.293V
2 Of the Batteries display the RUN LED blinking Idle (4sec) all SOC LED's are Off
2 Of the Batteries display the RUN LED blinking Discharge (2sec) Left 3 SOC Led's are On
I may have fixed the Interal Failure Alarm, one of the batteries had a DIP swich down, happend i think while installing. Although i'm not convinced this had any influance, because i have tried the system also with 1 or 2 batteries, where this batterij was excluded.
I have tried to limit the Charge Current, and Charge Voltage just above the reported Battery voltage, but to no avail.
I have kept the batteries connected as a set without the Multiplus or the CAN bus cable multiple hours and a night.
So currently my main focus is why the Multiplus trips the 25A breaker when starting with the DC connected. currently i ave no idea what to check or change.
If there are any details needs please let me know which and i will supply them.
Thank you.
