[RE-wrenches] 120/240 Delta

[Kienan Maxfield]

This is easily within the capabilities of Victron. Victron can handle any
of these voltage configurations natively without need for extra non-Victron
adaptation hardware. This would not end up being an amalgamation of
hardware.

I am curious which two legs were run and what you’re line to line voltage
is and line to ground voltage (from each line) and all of that.

I am also curious how many KW your target size is

Thanks,
Kienan
