Watts are still watts. If your output watts are 600, the inverter's input watts will be, in theory only, 600 watts. So a 12 volt battery will need to produce 50 amps to equal 600 watts. My guess is the inverter will use some watts too, which will add to the 50 amp total. Divide your watts by 12 volts and that will be your amps. Guessing you have 12 volt battery on tractor.
If I were trying to do what you are doing, I would keep the tractor or truck running at an idle or fast idle. The slower the engine is running, the less the alternator can produce and IMHO the less stress you will put on the alternator.
I have a 10K dump trailer with a 12v hydraulic pump. I wire my dump trailer battery to the tractor's battery. When I make a dump, I slow the tractor down and watch my ammeter. Usually at an idle the alternator is producing 20 amps. It's a 61 amp alternator. To date, I haven't fried my alternator. At the end of the day, I put a charger on dump trailer battery to bring it up to full charge. You may want to do the same. George

I really hate to see a good tractor being treated that way, but not being able to start it without a 30 minute point filing ritual every time contributed to its demise. If it would just start when I turn the key, then I would use it more often. In addition to a bad case of old age, most of the tractor's original electrical system was simply too unreliable to keep. The main focus of this page is to show how I upgr
