I neglected to put the price in. I'd like $450 for the whole lot but I'll negotiate on individual pieces.

[It should read 120 amps]

Ryan, I screwed up the subject line.  It should read 120 amps.  The full charge power from the big rosie. 

I am only getting half that so using twice the diesel and twice the running hours to get my batteries charged. 

Here is my original post from August https://midniteftp.com/forum/index.php?topic=9830.0

So I understand you currently have the generator feeding the Rosie so that one 120V side feeds L1 and the other side feeds L2 correct? And if you run in 120/120 mode the max charge you can get is less than 60A DC? It would seem to me that with L1 and L2 in phase and Rosie set to 120/120 it should charge as though it was a single 7500 watt inverter. Can you check this for me by going to these pages and snapping a picture while the genny is running and charging

SETUP--> SYSTEM CONFIG (So we can see the topology etc)
INV button and scroll to the right one click and snap a pic of this

There are "interdependent" registers involved, that means some can't be higher or lower than the other.  I made a web interface to test with, here is a clip of it so obey the comments and you can make the changes.

I was able to get the examples you showed to change, except the Grid Sell would not change.  Mine is currently 'enabled' and it would not disable. This setting should not have any dependency, either on or off. The other 4 items under the Battery tab would not change. I tried changing one, then the other, recognizing you couldn't change a cutout voltage higher than the connect voltage.  No luck. Have you been able to actually change the 4 battery settings I listed?

You may need to update the MNGP2 with the new Beta code

Solar Assistant just finished the controls side, Look for the beta version of the Solar Asistant from about a week ago or newer.

What are the issues with 10-12 beta and can you be more specific on the version with the full number and that device it is

Not sure if these are BUGS or just not programmed as yet.  When you select EDIT, boxes appear at most all line items.  Can these be changed???  Before hitting Edit, there are just 4 items that have BLUE arrows, does this mean only these can be changed??  There is no legend/instructions for this at the moment.  IF, and it's a big IF, we can change any perameter that has a box around it, There are a few bugs in the Solar Assistant Beta, at least for me .  Under BATTERY - Edit, trying to change any of these 4 registers results in a "Rejected (invalid register) ERROR: 
To Grid Battery Voltage
To Grid Battery Capacity
Back to Battery Voltage
Back to Battery Capacity

Under Input/Output:
Grid Sell

My Rosie firmware is 2025-11-13, Solar Assistant Version 2026-10-27.  Was the same in previous SA version.  I haven't tried all the possible edits that SA now appears to offer, but these are the ones I'd certainly like to change as the defaults that SA has in place are not good numbers for Lithium batteries!

Brucey mentioned you were going to discuss this with engineering to see if firmware could fix it. 
I was also wondering if my gennys 37amp output on each leg could be tuned to allow it to charge 60a at 56v. There should be enough watts available (4400w vs 3360 needed), I think I was told the Rosie allows 3500w on each side.  There are 10's of thousands of these gennys out there in diesel pushers. I know Tiffin installs 240v Induction stoves in their most expensive coaches if they didn't require the genny running to use them would be a really sweet upgrade. -Bill

PS.  I talked to lots of Midnite folks prior to buying the Rosie, sure wish someone had mentioned this gotcha so I could have made a more informed choice. Now each time I run the genny I am reminded of this issue.
