Pure sine or standard inverter
How big of a deal is a pure sine over a standard inverter? I now use a standard 400w to run the TV and direct box it dose fine. I am thinking of a 1500w to power the whole 5er, coffee pot, microwave, ...

For most loads, the MSW is lower cost, and will work well.
The two exceptions are a laser printer that will not work from MSW power, and the microwave that can not work from MSW without damage to the microwave. I had to replace my microwave after running it from my Trace M1512 inverter for perhaps 10 minutes (a couple of minutes at a time). I would have been much better off using my built in Onan generator, it needs a little exercise every once in a while anyway, and the microwave is a great way to load it up.
So I would recommend staying with the 400 watt energy efficient MSW inverter. Larger loads should be run by the generator, unless you have a huge solar system, and 'want to'.
I am thinking about getting a 2 KW pure sine wave inverter, but really can not justify the cost. My Trace M1512 works great, is a 1996 model, and can run every receptacle in the RV. However it is not nearly as energy efficient as my portable 300 watt inverter. While watching TV, I can shut off the larger inverter, and start the smaller one. I will see total amperage drop from 7 amps to only about 5 amps, because the smaller one has much smaller capacitors to charge, and generally uses less power for say a 150 watt load.
Good luck,
Fred.
