The Rosie / SA update to Rosie settings
Last post by bigbillsd - October 17, 2026, 12:13:19 PMAnyone with a Big Rosie looked at this new feature in solar assistant v2026-08-25 Stable?
It adds this: Add battery setting support to Midnite Solar inverters.
Considering updating SA. Not really sure what that gives me. I have found updating things does not always make things better, this has been out going on two months now. And I don't see any midnite fixes listed for the 10-12 beta..

Last post by Wizbandit - October 17, 2026, 12:06:08 PMYes, that is known bug in that version firmware, update to 26.1.14.0 and it will be fixed. This version is on the MN Production app (magenta/purple app icon).

Hawke's Bay / Hawk's Bay still not working c...
Last post by qrper - October 17, 2026, 11:58:29 AMHi, everyone!
Still have unresolved problems charging with the HB, and frankly, it's really getting under my skin.
I have 6kWp array. Bright sunny day. It's 50ºF outside. Batteries report 75%, and the HB is producing ZERO current!
Now, give it some time, I didn't keep track of how long, and I start to see current flow. At one point this afternoon, I was watching 65A going into the batteries.
I did notice, the current dropping and it went to zero, yet the sun was shinning. HB was reporting BULK charge, but wasn't.
Then checked it again ten minutes later, ZERO power. Same sun, same batteries.
That's not low current. It's ZERO current flow.
HB reports 470ish volts with no current being produced. Batteries at 75% so there is plenty of storage available.
I don't know what's wrong. Is it the HB? It's not warm, fans don't even come on. No breaker popped. Everything appears as right as can be, except on a perfectly sunny day with 6kWp array into batteries that need charged, the charge controller is setting at ZERO current.
Using my old lead acid batteries and the Classic 150, same array, same sun, I didn't see any such operation.
Yesterday, HB reported FLOAT, and ZERO current flow, yet the batteries were being discharged at 12A!
How is that even possible? Float with no current to the batteries, yet the batteries are discharging?
Firmware is 25.12.2

Last post by bigbillsd - October 17, 2026, 11:55:28 AMQuote from: Brucey on October 16, 2026, 11:42:17 AMMy understanding of the issue is that the Rosie firmware assumes 120/240V operation, and therefore it halves the max breaker size value, even when set to 120/120V mode.
I will keep my fingers crossed that they can change that assumption with a firmware fix.
Should I call them to officially request this fix? That one fix would make the Big Rosie a real world device for the majority of the diesel pusher world! The only other thing that is odd is the grid support but maybe other folks would think that is normal as I don't have any experience with other implementations of grid support.

Last post by Brucey - October 16, 2026, 11:42:17 AMQuote from: Wizbandit on October 15, 2026, 05:21:24 PMDid you try setting topology to 120/120 and see what it does? I have never tried that without at least paralleling AC ins. It probably won't work but try it. It probably needs a new section in firmware to allow it but wouldn't expect to see any firmware work this year or even early next year.My understanding of the issue is that the Rosie firmware assumes 120/240V operation, and therefore it halves the max breaker size value, even when set to 120/120V mode.
Now two little Rosies working independently would work fine, they can't be stacked so they don't care about phase.

The Rosie / Re: Rosie is dead.
Last post by HIT99 - October 16, 2026, 11:14:28 AMI have my Rosie up and running as before.
A backup inverter of some kind is a good idea if you live far away from everything as I do. It is hard to eliminate all the critical points of failure. Our propane dependency has decreased over the decades which has changed the solar from nice to have to critical.

Yeah, Ryan had me try that. It didn't make any change at all so after a few charges I moved it back to 120/240. -Bill

Last post by bigbillsd - October 15, 2026, 03:50:28 PMQuote from: Brucey on October 15, 2026, 02:31:22 PMHe's saying to feed both 120V outputs from the gen to the Rosie (keeping them seperate). Not to connect them together before the Rosie.
Not to combine the 120V outputs
That is how its been setup since Day 1. L1 & L2 into the Rosie are connected from the QD7500's two 120v outputs. (not 240v) -Bill

The Rosie / Re: Rosie is dead.
Last post by Brucey - October 15, 2026, 02:39:21 PMThanks for the update. I recently picked up a little rosie as a spare inverter in case anything happens to big rosie and it has to go back to Washington for warranty work.
