Also worth noting that I haven't had time to get to the parallel operation code again.  It's technically possible, just not yet implemented.  Trying to sort out all the manufacturing/factory issues/challenges at the moment.

I know this was from nearly a year ago, but haven't been able to find anything more current... is it still true?

What options are available for converting from 240SP to 120 for Split Sync? (I already have 2 6k's.)

Unfortunately it still is true...as sorting out all of the production shenanigans has taken almost a year.  Looking forward to being able to get past "damage control" mode...

 

The tests I did several years ago showed that the functional concept appears to be good...I just need to reimplement it with the updated monitoring possible on the Rev. C boards.

 

Reconfiguring the inverter output voltage is one of the simpler mods you could do; @sean-genetry-solarshould be able to walk you through it.  It basically involves going through the software unlock on the inverter, changing the config to 120v, and then rewiring the internal transformer secondary leads.  (You don't need to buy anything.)

So, we tried getting Daisy to work...it didn't, so Plan B is go with 2x120v Split Sync...Slave just sat there in AC-Pass-Thru when the second (Normal) inverter was powered up...

 If you're not using AC input, you can "borrow" a line from AC Input to double up both Hot and Neutral output.)

I'll bet this doesn't apply to Split Sync...

Sean sent me an image...looks like other than beefing up the thin wires, there's only 1 add (a jumper from N to O-L2)...

(Not forgetting the output setting change to 120v.)

Waiting on some ring terminals big enough to handle 6 AWG...in the meantime, I'm planning on some photos of what I think I'll need to change (to verify that I'll do it right).

No rush on this Sid, so don't mess up your vacation to reply right now...
