Greetings to all.

 

I have purchased this inverter and it was installed for me with 2 x 100ah AGM batteries. I do not have any solar panels and use only utility power.

 

What are the best settings to use? At the moment the batteries are always charging and the fan is always running at high speed (the second light is always flashing green).

 

Intermittently the second green light will stay on for less than a minute and the fan will slow down. In less than a minute the green light will once again indicate the battery is charging and the fan will speed up again.

 

Is there a setting that can be changed so that the battery will not continuously be charging and thus the fan be quieter for longer periods when the utility is providing power?

 

Your assistance will be much appreciated. 😉

 

Thanks

Dave

 

 

I have exactly the same model which was installed just yesterday.

I've found the fans quite disturbing and would be delighted to hear if there is a solution.

Have you guys found any solution to the fan issue? I’m also looking at the 3KW Growatt inverter and am interested in the gprs remote monitoring, Anybody using  it with any success?

I'm not sure about the 3kw models but with the 5kw one, the more load you put on the inverter, the louder/faster the fan runs. Try reducing the load and see if this is the case. 

This has been a major annoyance of mine.  I have the same model.

It has nothing to do with load on the inverter - i am currently using the inverter (loadshedding at present) with a draw of about 300W and the inverter is QUIETER than when there is no loadshedding, no draw (0W) and batteries are at 100%.  In this instance the inverter should just be in trickle charge mode - with barely any cooling necessary - but it blasts it fans on full. 

Any feedback that resolves this issue for a Growatt SPF 3000TL HVM-24 would be well received.

Has anyone tried opening the inverter and replacing the fans with custom quiet ones? Noctua fans maybe...

Hi I have the same problem with the fan staying on battery full .no load but stays on low.My Must inverter stays off when fully charged

Struggling with this too! 

It is so loud and irritating - even though we haven't had load shedding in a week! 

I've turned it on standby but still sounds like we live in a server room - I'm worried about our electricity consumption. How do we turn it off totally? 

The secondary DB board is off so the house is on Eskom power and battery is full. 

Thank you!
