Hi, thanks for letting me join your community. Apologies that my first post is a problem question, but hopefully as I learn more about these devices I will be able to contribute something as well!
I recently purchased a used Phoenix 24/3000 inverter with the following identification information:
External:
PIN024302000
06290800933
Internal:
MCU Firmware 1812144
PCB 010021
PIN 24/3000
2021070035
06290800933
It worked perfectly for the first two weeks, but now it has developed a fault where it will not power-up. I have not overloaded it (max load has been around 1000w and fan was heard cycling normally).
The symptoms are that immediately after switching on (even with output terminals disconnected) it does one of the following:
- Produces correct output voltage for about 4-8 seconds with green LED on and overload LED flashing, then shuts down with only the ‘Overload’ LED is lit solid.
- Does not power up at all and only the ‘Overload’ LED is lit solid.
I’ve checked all the obvious things like battery connections and voltage at busbars, tightness of all nuts/bolts in the DC bus, re-seated all internal connections between circuit boards, looked for any obvious internal damage or signs of overheated components on the PCBs. There is no evidence of thermal stress on the PCBs or transformers, no corrosion or any other damage.
There are no unusual noises, just the usual quiet hum of the transformers until it shuts down.
I was hoping to get some useful diagnostic information via the RS485 port and Victron software as I have a generic RS485 to USB converter, but I cannot find the pinout for the connector on the control PCB, nor the baud rate used by this device.
Thanks in advance for any help.
Paul.
