48/5000/70 on/off switch

Hi all…

That little on off switch… or make it the 3 way switch.

off middle I on one side and II on other… please educate me on the 2 on positions.

It’s I at the moment… if/when on I if II disconnect main then everything switches off


Position 1 is normal operation, position 0 is Off and position 2 is Charger only. In charger only it will pass AC through to the loads and Charge the batteries at the same time. Should the grid fail the output will also be off.
