My neighbor in CPT want to remove his Fivestar 3kva 24v and replace it with either Growatt 3kva or Rct 3kva vmII. As i don't have much experience with these smaller type inverters i won't give him the best advice or rather wich would be the best fit. He has very moderate load as this powers his granny flat with max 600w load. He has 2 x 330w solar panels installed. I would appreciate some feedback as to which make would be the best buy.

I would look at the Must or Solarwise 3kVA as well. The Solarwise is a 30A AC charging and only 40A DC but being lower rated it might be more reliable. Both have MPPT controllers. 

A lot of the better priced units tend to have a PWM charge controller and I don't fancy them. 

I don't have experience of them I have to add. If Thesunpays still offered a similar clone to what I got I would have put it 1st in the queue. 

I would go for the RCT, if the Voc voltage of the solar panels are high enough then one can consider the 3Kw VMIII offered by Axpert or Kodak.
