I have a feeling many here assume that you will draw all 2000 watts all at once for prolonged periods. That’s like running 20 100W light bulbs That is a silly assumption.
- 2 burner electric camping stove 50amps
- electric chain saw 12-15 amps
- battery charger 20-50 amps
- cordless drill battery charger 14 amps
- Camping fridge ~50 amps (when cooling)
As said previously, if you use a second battery, isolated from the first one, you will not have to worry about damaging or running down your main battery. My son-in-law had an inverter in his camping truck for many years without any problems. Enjoy
