Hello Victron Cerbo GX Firmware version v3.53. The time cannot be set, it restarts and shows 10 hours more than the real time. Thus, it cannot measure real consumption and production. Can someone help me, tell me what could be the reason for this? Thank you in advance

Hi guys I finished the solar park.

Hi. I've tried a lot but this morning the red X says there is no WiFi and there is.Could someone help me. It’s been working properly for over a year, it doesn’t want to work today. Thank you in advance for your help. Greetings Antal

Hi I did it and it works for 2 weeks now. Greetings Antal

Hi It works like this, I can't solve it any other way,it is not possible. Thank you in advance for your help. Greetings Antal

Hi I removed USB, for 24 hour. The result is this: Greetings Antal

Hi Mike_C I think 1 month. Remove USB, for 24 hour. Then put it back and after 20-30 minutes you will see the backup has this data or no data. I'll try it tomorrow. I will write the result. Greetings Antal

You may be right about that! The only question is what date is the USB dongle?

Password is ossyyyymmdd

Hi This can be a problem if one wire is longer than the other? I can't solve it any other way. Greetings Antal

Hi Mike_C Thanks for the reply. It works on the inverter, but unfortunately not here. This doesn't work either 12345678 00000000 11111111 I have tried many different combinations but none of them work.

Thanks for the answer. I know this, it was just this old system with 2 separate types of inverters & panels. Then I have to remove some panels to have the same voltage. MPPT 2 I install new identical panels. That's how it should be, so the difference between VDC and W is so small that even a shadow makes such a difference. Or I think wrong?

Hello I have 2 different strings. This can be connected to MPTT 1,as shown in the drawing? I will connect the new MPTT 2 panels so that their performance will be the same. Thanks in advance. Greetings Antal

Hello Can someone help me with what the password is here? Control Password ? Thanks in advance. Greetings Antal

Hi The program was started after several attempts! It can only be programmed from a laptop! Greetings Antal

Hi Thanks for the reply. Can someone give me an address where I can buy a display. I tried it in Alibaba, but they don’t want to sell a display separately. Greetings Antal

Hi Thanks for the reply. One more question. Before I program. The switch must be ON or OFF state? I know only the battery can be connected. Greetings Antal

Thanks for the reply. If I understand correctly then upload version 2.xx and it should work. Greetings Antal

Communication lost during update. How to solve the problem now? The display does not light up. Greetings Antal

Hello The display does not light up, in which case software can be updated? Greeting Antal

Unfortunately no, he goes to sleep mode. Only PV can wake you up. Or manually every morning. The first picture shows the factory circuit. Today i tried the 5v trigger and it started. Or a small PV panel, just for the trigger. No need to worry about 450 VDC.

The battery pack goes into sleep mode in the morning. PV turn on the battery pack. I draw the circuit. But the PV of this is only 145 V. The AXPERT VM III PV 450V. Do you think i give the value of the parts well?

Bad news. Manufacturer replied. Because we do not have protocol of this inverter.

The updates were in pairs. The LIB I tried has the same warning. I'll try them all. I write the result. There will be no bugs with version 2.61. The main processor version 91.20. The connection is now visible.

I tried to do another firmware but the error is the same: 61.
