If I understand correctly, you have a 12 Volt battery rated at 35 amp hours and want to connect this to a Go Power Industrial Pure Sine Wave Inverter, # 34278156 rated for 2,000 Watt. If you want to operate anything for an extended period of time that needs that large of an inverter then you would need at least 400 AH minimum in your battery bank. So no less than 12. However, trying to wire that many batteries together will cause use of a lot of wire that increases resistance, so be aware of that.
