TBE INVERTER 2000W WITH BAD SINE WAVE

This inverter it is sal in Romania in description like pure sinwave but is not true.I buy a scopemetter to see if istrue or no. The seller who sell me is online seller namedcudetoate.ro. I tested the inverter with an electric grind 720W work well but I feel a strange noise.How I present in video exist the danger to discharge at minimum the battery because the inverter fan is running. I bought this inverter in the year 2013 but now I have it the scopemetter. I hope this video is helpful for others person who want a product of this kind. Best Regards Hristea,
