Hi Mac,

It's always the inverter that you powered up first.
So you get to decide which one is the master.

FYI- this can cause problems with customers that fiddle around with things and
turn the inverters back on the wrong order.....fun ;-)

Hello wrenches,

I recently series stacked two SW 4024s.  Everything seems to work fine.  I want to follow the recommendation that the slave device is the generator controlling inverter.  How do I tell which is the master and which is the slave?

Thanks
