Hi Community, my ESS (Quattro 48/10000 4 x Pylontech 5000'sve has been working great since install however I am suspicious of the Quattro internal cooling fans not switching on. Does anyone know if there is a signal I can log through VRM which indicates when the fans are active or not, such that I can see review back over a period of time? I suppose if they are not switching on any fault finding info would be appreciated.
If you have a heavy load on, the fans should switch on. Also under heavy charging.
If the fans are not running and you run heavy charging/loads you will see temperature warnings or alarms and the system will shut down.
You can so metimes tell in VRM if there is overload warnings but inverter is not running near full load (so points to derating due to temperature) - be careful here if your ambient is high.
Do you have a Cerbo GX?
You could book up a temp sensor and have it hang around at the top of the unit. They do run quite hot.
You could also set up a programmable relay to switch on and off based on the internal fans, wired to a digital input (maybe set to door alarm or something) and have an alarm based on that.
I don't think there is a way to tell if the fans are actually running (other than physically checking) but you will definitely be able to tell if the signal is being sent to run.
You mention that the CerboGX can have one of its programmable relays activated when the fans switch on, I was wondering whether this could be monitored as an alarm on VRM?
I actually suspect the fans are not being activated so in some ways this is about fault finding and knowing that the fans have been given a signal to run should help me to identify the issue.
Any further advice would be appreciated.
Best Regards
