Local App software / Local Status Panel will not po...

Last post by SDman - April 01, 2026, 03:55:16 PM

Hello all - new to the forum and looking for some guidance.

Have a Classic 150 and Lite 150 connected to the system since 2014 and had read consistently until the last yr or so.  That is, when pull up the app on computer, neither will pull up (device not available) with the IP address or, it will only pull up one of them, but.....it will not populate any data at all.

I've pinged them and they all come back with no packets lost. 

App is set to autodetect.

Any guidance on this besides potentially changing DHCP to a fixed static?

I think the email system that sends out alerts about responses isn't fully setup so the sender cannot be verified.  My guess is its missing SPF or DKIM security records for the MX configuration.  I would imagine most larger email systems stick these in the spam folder like gmail does.  That causes me to miss them for days.. I'm probably not alone.  This is not a new situation.  -Bill

The Rosie / Re: Parallel Rosies not sharin...

Last post by FNG - March 31, 2026, 11:27:06 AM

I have an off grid system installed with 2 Rosie inverters in parallel. The AC input is a 14 kW generator. When generator charging the Rosies don't share equally. Also, sometimes, not long after a generator auto start charge cycle is completed there is a fault code for AC overload on L1.
I've attached 3 pictures. One shows the FW in each component. Left and Right are two different MNGP2 displays. Master is the master Rosie. Rosie is the slave Rosie.
The others pictures are summary's of the inverters activity on the same day when a generator auto start occurred to charge the batteries. As you can see, one Rosie took in over 7,000 watts for long enough to take in over 49 kWh. The other Rosie shows all zeros for the same day.
I thought maybe the parallel threshold was set to high at 40% but I didn't think that affected charging, just inverting. I changed the parallel threshold down to 25%. At the time the generator wasn't running and total load on the inverters was about 1 kW. When I lowered it to 25% the slave inverter came on which seemed strange with such a low load.
Any ideas are appreciated. I don't know if this is multiple problems or if they are related.
Thanks for your help.

"Stacked" Rosie inverters do not share loads ( and apparently charging) equally when there is AC IN I'm told.  Things like AC IN wire lengths may cause voltage drops between inverters and the balance issues.  To properly balance AC IN operations (and SELL MODE, which is not yet available) will take "Closed Loop" communications between all inverters which does not happen with the present firmwares...

We can hope the engineers will find time to add this feature in the future but it does not seem to be effecting very many installations right now so it's low priority.

I think what Jim (Whizbandit) meant to say is, Stacked Rosies may not share equally IF in grid support mode. Even then if one is doing more than the other the lagger will throttle up as the leader gets towards its maximum so for example if your are in grid support and have a 10KW load one Rosie may run say 6KW and one may run 4KW but if you had a 3KW load one may run 2.5KW and one runs 500 Watts

When in normal mode or off grid they share within a few hundred watts. Also when charging they share within a few hundred watts.

If you have a stacked set of Rosies not sharing and they are NOT in grid support its likely a wire/breaker resistance issue

General info / Midnite Classic data to Home A...

Last post by qcda1 - March 30, 2026, 05:52:48 PM

If it can help, I just finished a Home Assistant custom component that can read pretty much all the Midnite Classic's registers and more and create corresponding sensors/entities in Home Assistant that can be used to control and chart stuff and feed the nice Sunsync power flow chart.
The custom  component is in GitHub at https://github.com/qcda1/ha_midnite_classic

At installation, the user can select the values he want to be created as entities in HA from a total of 54 from which 11 are selected by default. The sampling period can be specified from 30s to 1 hour. The Classic must be on the same LAN than HA and a host name should be configured as this will be the name of the equipment in HA.

Attached is a sample installation picture:

Regards,

Daniel.

The Rosie / Re: Pros and Cons of Closed/Op...

Last post by bigbillsd - March 29, 2026, 01:09:53 PM

Which simply doesnt happen when using open loop and a shunt, because the shunt can detect much smaller currents.

I will be using a repurposed BMV 712 shunt.  That is also something I will need to get into SA.. 

I did try connecting my ECO's to the Rosie just now.  The MGNP does now give me SOC so I am thinking it may be working.. sort-of  Nothing in SA anymore for the battery. 
I do not seem to have a way to terminate the bus now,  I plugged in the SA RJ45 into the MGNP second port and I plugged in the batteries into the Second Port on the Rosie.  Now I am wondering how I can terminate it as there are no more ports on the CAN bus.  I was googling a hub but not seeing much except stuff dedicated for certain printers.  I was thinking I needed termination on Both sides.  But it looks like it may be working without termination.  Not a lot of Canbus errors on the MGNP.  At least they do not seem to be incrementing up.  I am thinking I am only seeing the First ECO battery.  Each battery has a CAN port.  Maybe I need to daisy chain them.  But not sure how yet.  There are a lot of ports on the front of the batteries. 

I connected the Rosie CAN port to CAN on the front of the battery and it seems to see one battery.  Then I added 3 more Twisted Pair cables, from the RS485-1 to the battery below's CAN port, same for the next two hooking up all 4 batts.  I am pretty sure I am still only seeing one battery in the MGNP2 and SA.  I saw Ryan's example and he sees all 4 of his batts.
If you see the IN RS485 Out ports on the right, I am using that for the EcoWorthy Battery monitor screen.  But they are not RJ45 connecting, look like the 4 or 6 wire RJ's

The Rosie / Re: Pros and Cons of Closed/Op...

Last post by Brucey - March 29, 2026, 11:35:10 AM

Hi,  I have installed Solar Assistant (SA) after watching Ryan's webinar and its working great.  Now I am looking into getting the Batteries in there (4 ECO-LFP480002).  That led me to wonder if I should do closed Loop (CL) or not (assuming CL would give me a view into all the batteries in SA) add another CAN to USB for the SA raspberry. 

Those Eco's are PYLON so it might work..

Currently the comm's are not fully understood. 

What I have read is if I can do closed loop, that will take care of all the battery settings for the Rosie, which sounds pretty good to me.  And as a potential added bonus it might populate SA for me.

What are the Con's to using the Rosie in a Closed Loop?   

-Bill 

Depends on what your loads are. If below say 100W per 5kWh battery then the bms won't see that small current draw and soc will drift from reality. So if idling very lightly overnight you could be in for a nasty surprise when eventually system shuts down due to low voltage while soc happily says plenty of % left.

Which simply doesnt happen when using open loop and a shunt, because the shunt can detect much smaller currents.

Having identical length wiring for ac input to parallel inverters is best practice.

[I have experimented with closed loop for Hawkes Bay in the past but before all the latest firmware updates may have fixed some issues. I also experimented using closed loop for an EG4 and Victron . I always went back to open loop charging so far because that gives me the exact control that I want and understand. Closed loop always made charging decisions that I did not fully understand . And that is with my JK Bms that I had configured the setpoints how I wanted them to be. The bms setpoints should be making some of the charging decisions. I don't know anything about the Eco batteries you have or what the bms setpoints in those are. My only advice is when you get the closed loop running is to watch what it does closely and see if that it is doing the lithium charging concept that you believe is best. There are lots of different view points of best lithium charging strategies out there . They may all be correct or some may be better for different systems , etc. Regarding monitoring your batteries closely , if Solar Assistant doesn't do what you want, look into Home Assistant add on's to see if that will. I just took a quick look and seems like it is possible to get add on's that can get Ecoworthy battery cell information via bluetooth. My JK Bms has support so I get some very nice detailed info shown in the photo here. Larry]
