I'm looking at a 2000w pure sine wave inverter and the prices are all over the map. Can anybody explain the difference between a $200 unit and a $1000 one? They all seem to have the same features...
INVERTERs are a known hugh source of RADIO FREQUENCY INTERFERENCE. If this is a concern for you then then higher cost model may have extra circuitry to help keep the RFI to a minimum.
My cheap PSW 600W and 1500W INVERTERS really eat up my HAM RADIO operations with loud BRRR's up and down the frequency bands. Especially bad in the 7MHz band range...
