Fujitsu defrosting hourly

I had a Fujitsu mini split installed a couple months ago for heat, Some times it defrosts as often as 40 minutes after the last time, and can take up to 20 minutes. Is this normal??

    Not to contribute to the problem...

    What temperature is it outside? My 12RLS goes into defrost a few times a day and may take 5-7 min to defrost. That comes in at around 32F. It then immediately comes back on and rocks heat output wise. Your refrigerant pressure may be low.
