Thanks!

The battery terminals.

You will need a large (physically) resistor to do so. And it will get hot.

In all honesty (it is safer to) disconnect the battery bank and an other sources, switch the inverter to on and wait a bit.

FYI these are the same capacitor bank that needs to the precharge as well.
