Hello Gog,
After repairing a couple of these cheep inverters, and talking to a professional repair shop -- I have seen and been told, that there is only about three companies building these, and they build for many "brand" names !!
After takeing several apart, I noted, inside, they were almost identical and appeared to originate from the same source !!
I found them difficult to repair, and of the couple I did have success with, they didn,t last long, before other associated parts failed -- although the mosfets, seemed quite durable, other small parts weren,t -- just one thing , takeing out others !!
I finally went to the heavy duty Tripp=lite unit, that weighs in at nearly 40 pounds !! Expensive, but it lasts !!
Other than that though, I would mention that a 1500 watt unit, seems fairly lite, to be running a freezer on and I,m of the opinion, that the cheep units, are more suted for running lights -- even though I used a 2500 watt "Mobile power", unit, to run a lot of drills, sabre saw, skill saw, and chopsaw -- it gave up after a couple of months of abuse !!
The thing is though, you can buy an awfull lot of cheep ones, before you reach the price of a "good one"...Just depends on how important it is to you !!
Good luck to you and happy building, Bill H......
