Starting batteries instead of deep cycle
So I’ve got a theory... Deep cycle batteries are designed to slowly discharge low current for a long time. Starting batteries are designed to put out high current for short periods. Generally, p...

For that application Marine batteries may be ok.
The best may be an AGM chemistry.
2000 watts = a draw of 200 amps @ 12 volts. So 8 12 volt or 16 6 volt would be ideal. (that limits demand to 25 amps per cell).
The problem with using starter batteries is that they may sulphate quickly and they want to be recharged *RIGHT NOW*. Of course, it can be done.
^This.
I think Your best bet is upping the voltage of your DC system. Convert to 24/36V to lower the amp draw. Although idk squat about inverters if they can take any DC voltage or are specific to one type of voltage.
Series lowers the amp draw per battery or cell.
Disclaimer, I'm pontificating...and not an electrical engineer, lol.
