Growatt 6KW Fan lock error

[Jonathan3900]

Good morning:

I have a Growatt 6KW Inverter. I have 6-350W panels on the roof, 2 Big Battery Husky 48V batteries, and a Generac 7500W generator.

I have started to get fan lock errors. I have searched and can't find much of a reason. Any ideas on why I am getting them?

Thank you,

Jonathan

I'm getting the same thing. Every day at just after midnight I get the error. Sometimes during the day. The local solar person who installed my system doesn't know. And I can't find anything from Growatt and the app doesn't give any information

There is a firmware update that addresses this problem.

The update process isn’t difficult, do a search on this forum for several documented examples.

For peace of mind, if this can't be done for several months (maybe 6-7) I can ignore the errors and it won't be something that will be a much bigger issue at that time?

When I had the fan lock notifications, there was actually no problem with the fans.

I have just replaced the 3rd fan in my 2x spf inverters and expect to replace the 4th soon . This failures started during the warranty period and it was far easier to change the fans that change the inverter. The fan lock is a warning that one of the fans is not working . easy job , remove both casings , 4 screws , 1x plug and swap out . I had 2x fans sent from supplier and now I buy them locally , just a 12v , 80mm computer cooling fan but with 4 pin plug.

I had the issue and fixed it with firmware then it came back. I asked for help but the inverter charger board burned up during the slow process to get help. It appears the fan had stopped intermittently. It was within the warranty period.
I would recommend you check your history data to make sure the temperatures are not getting elevated if you cannot address it immediately.
