Hubless and Masterless Outback Inverter Usage

[Eraser3000]

Does anybody have any experience getting the Outback VFXR Series Outback inverters to run without the Outback Hub ?

Essentially I want to be able to run the Battery Inverters more like the String inverters but also be able to deliver power from batteries when required.

I have this working on the bench with two inverters and will be retrofitting this into the rest of my system, but I though I would try to get some feedback from anyone else already doing this.

Thanks!

Yellow is Test Inverter 1, Green is Test Inverter 2

Red is a 0 to 15 volt Square wave, Slave Inverter syncs with this Square wave.  This is on Pin 4 of the RJ45 on the inverters.

Red is Data line Pin 5 on RJ45   Serial uart running at 1200 8N1 .  This has to be there and is transmitted at 60Hertz
My guess is the voltage is so high because the anticipated running up to 10 inverters on 1 hub and have to account for max distances on all of the cat5 between hub and inverters.

This is interesting in that  00001111 = F = 15 = Ascii (SI) = ☼  yes! the Sun, very nice touch!
