TERRIBLE AFTERSALES SERVICE. Over the years have bought many Renogy products I have been happy with. 1 issue over this time that required me having to contact customer service. A missing remote from my inverter and Renogys solution is essentially "too bad, so sad". They are unable to provide me with a remote switch as they do not sell them separately. Open a box and send me the remote you would have been the correct thing to do. Instead I am now faced with spending several hundred more $$ to purchase another brands inverter to replace this unused Renogy. What a waste of $250. I'm sorry Renogy but you will never see my money again.
