Mecer Axpert 3000va Fan running continously under PV

No need, I remembered! 🤞🐘

Yes, that firmware series (02.4x and I'm guessing also 02.5x) seems to handle 6 models, including the 48 V / 3000 VA / 2400 W model that you have.

So I take it that we should just stick with what we have. If it isn’t broken then don’t fix it. 
thank you for all your help.

Hi all,

So I have a 24v Synapse 3.0v+ 3kva 2.4Kw inverter and I have a similar issue. 
 

My unit is brand new, and I have changed the settings to a point that the fan is not on all the time. Seems to be on for about 45min and off for about 20min. (Approx) This is with no load at all. (Have set bypass mode, so when utility power is present all load is on utility anyway) Batteries fully charged. Temperature makes no difference. I am not running any PV.

Any advice?

Cheers
