Choosing an Inverter
If I'm in the right place... Looking for an inverter that will run a 1875w +/- hair dryer, 700w microwave (which really takes 1100w), and both sides of an electric blank, the controllers say 180w. ...

If I do my math right, running a hair dryer once every 3 days for 10 minutes is 25A. If we run the MW at all, it'll be for maybe 10 minutes a day, or 15A a day. Another 20A for misc for 130A every 3 days, I have enough solar and batteries.
A*H= AH, not A.
And, - sorry to disappoint you but you math is wrong. Read on Peukert effect. 1875W drier will need 160-165A @13V, considering inverter losses. At this current the battery will probably lose more than 60AH in 10 minutes. Depends on battery type and size. This is a non-linear effect. You can't just use a school arithmetic. There are spreadsheets to calculate the actual AH draw with Peukert.
