inverter/ power source for mobile business? help:)?
I have a mobile business and need an inverter to run no more than two items at one time. The largest two as far as wattage being a room air conditioner and a forced air dryer. I have deep cycle marine batteries in a series as a power source. Can anyone recommend a brand of inverter (thinking 10000 watts continuous) and how many batteries would you have in the bank? Basically it will run the ac continuously for 6-8 hours, small no heat dryer for 3 hours total (not continuous) and other smaller items for short periods of time. Also, thoughts on pure sine wave vs modified. I am trying to stay away from a generator for various reasons including noise and not wanting it to look tacky mounted to the back of my vehicle. I realize there are a lot of variables here but my crappy 5000 peak watt inverter is shutting off when I use my dryer...need that to stop and need to add ac. Want to be able to work on my vehicle without it or a generator running continuously. Thanks.

You really need to consider the alternatives carefully. lee26loos' calculation of battery requirement is over the top, being based on a load you are never going to need. If you are considering a 10kW inverter to cover a peak 9kW for 4 hours and 6 kW for another 4 hours (for example), then you are talking only 60kWh, which could be 5000 Ah @12V or 1250 Ah @48V. In real terms, though, this is still the equivalent of 50-80 car batteries, weighing over a ton. This is not a mobile exercise.
Actually I wonder if your inverter is as crappy as you make it out to be. A 5 kW output would require an input current @12V of at least 420-430 amps (@48V 100-120A), and I wonder whether your current battery system is capable of supplying that. The best answer is to do the precise sums of the power consumptions of all your devices at peak demand and see whether you really need a bigger inverter or simply more batteries in parallel. I still think a generator is the better option for this scale.

Buy this one, less than $500........

At 10000 watts load for 8 hours non stop, the 12V battery bank need at least total 6666AH. Minimum charging current is 666A for 10 hours.
