GROWCOL Variant VM IV 3600-24

Hi, sorry to repost, I think my post went unnoticed in an old thread.. 

Hello

I have purchased the Growcol vm iv 3600 24v inverter. 

The left fan spins up when the unit is idle and stops when charging or discharging. The right side fan spins up as it should. This makes the inverter unusable in my house. The fan spins up to high speed all the time. 

I've taken the unit back to the supplier the day after purchasing and testing. GC Solar. But their technical staff are completely incompetent and they also refused to take a return. 

Now I have to make do with the inverter. Is this firmware related? 

What are the risks if I connect the left fan in parallel to the right fan which spins up as/when expected

Any suggestions? 

Thankyou,
