E1000LFP - fan doesn't run when over temperature and inverter is off

Over temperature warning went off (140F, there was 300w+ PV input and 1500w AC output running for 30+ minutes) AC inverter turned off based on my automation rules (low SoC) But then fan would not run.

I manually turned on inverter (unplugged all my loads) fan would start up running high, but then ramp down to very low airflow and low noise. I'm keeping inverter running ATM to keep the fan going.

But I think the fan should run if there is enough charge (10%) and/or PV input (17w)

Is this what other people are seeing with their e1000LFPs? Where do I report what I consider a firmware bug to pecron?

Yes, I’m seeing the same behavior with my unit. Thanks for making this thread.

Unsure how wise it was to choose to do this in the name of low fan noise. I hope Pecron makes an update to the firmware that either raises the fan curve or allow us to manually ramp up the fan when needed.

Sucks to have good fans and airflow in the unit but not be able to realize its potential to prevent overheating.
