The Rosie / Re: Maximum output using gener...

Last post by Brucey - March 10, 2026, 07:34:31 AM

I realize the inverter will only do 30 amps. I was referring to the rest of the device: wiring, relays, etc. I think the AC output breaker in the Rosie breaker box is also a 60. Are you saying the Risie can use It's 30 amps of inverter capacity with 30 from the generatorfor 60 amps total to the loads? That would mean the breaker is good for 60 amps continuous?

My apologies I made a mistake in previous post. Please ignore that.

The breaker box uses MNEAC60 fully rated hydraulic-magnetic breakers that allow for a full 60A.

This post from one of the Midnite guys on diysolarforum should clear things up. Basically you need to enable grid support mode:

The way I read what @Halfcrazy said was that the grid simultaneously powers the load when battery SOC is below the settable percentage not above.

Correct. For example if you set grid support to 70% the Rosie will ignore the grid when batteries re at 70% or higher. Unless the load exceeds Rosies ability then she will pull the excess from the grid:

1- Battery at 75% and load is 5kw Rosie powers it all
2- Battery at 75% and load is 12kw Rosie powers 6 kw and Grid powers 6kw
3- Battery is at 69% Rosie powers no load and the grid passes through to power loads"

The "Classic" charge controller / ClassicBridge - Classic to Sch...

Last post by RJD18 - March 10, 2026, 12:42:50 AM

I am a long time Classic owner and have finally decided to take a shot at trying to integrate my Classic to the Schneider ComBox (865-1058) . Not to be confused with the Midnight Solar internal project of the same name.

My target  is to collect specific Classic parameters over the Classic Serial RJ12 jack and re-present these to Schneider ComBox via its RS485 using Schneider registers and in format , scale , offsets etc that it is comfortable with. In essence Making the Classic look like a friendly Schneider MPPT60.
I am doing this to enhance the LOCAL monitoring and logging via the ComBox that will result if I can get it working .

As of now I have assembled the hardware for this interface and have successfully bench tested the Serial RS232 interface (to Classic) and the RS485 interface (to ComBox) . I am currently crafting the Code and have just completed what I am calling 'Module 1' which is the system Boot and stabilization sequence.
I am just starting to code Module 2 - The classic polling engine.

I am posting to share with this group. I am happy to share progress as I move forward  and welcome any questions and especially welcome feedback of any gotchas from other users.
I realize that the ComBox is somewhat old tech but the approach I expect to be scalable / adaptable to other platforms that use RS485 Modbus.

Does anyone know how much power can you get out of a Rosie inverter using generator support? Is it limited to the 60 amp output rating of the unit or something lower than that? I'm assuming the Rosie would make it's rated 7 kW and use generator power up to 7.4 kW to make the 60 amp output. Is this correct?

Thanks for your help.

When there's AC input it can take 30A of 240V (or 120V), to pass thru to loads and use any remaining current for its battery charger. The 60A inverter output rating is a 60 second surge value. Otherwise it would be 30A of 240V (30A on each 120V leg).

So I thought to myself, in the past I simply ran a Cat line to the computer and the app found it and reported the results. Right? Not so fast I found out. This needs to go through the router.

So I looked up on AI the specs on the Uverse router, and it does not support the following information which I also found on AI. I see this has been discussed before.

MidNite Classic devices can operate with a dynamic IP address, but this requires additional configuration for remote access.
Remote Monitoring: To access your MidNite Classic remotely over the internet using a dynamic IP, you must use Dynamic DNS (DDNS). This service maps a consistent hostname (e.g., yourname.dynu.com) to your changing public IP address.
Setup Steps:
Assign a static IP address to the Classic on your local network (e.g., 192.168.1.115) to ensure it doesn't change.
Configure port forwarding on your router to forward a specific port (e.g., 502) to the Classic's static IP.
Set up a free DDNS account (e.g., DynDNS, No-IP) and configure your router or the Classic's settings to update the DDNS hostname whenever your public IP changes.
Local App: The MidNite Solar Local Application can auto-detect Classics on the local network and connect to remote units via DDNS or static IP, supporting both Dynamic and Static IP setups.
Important Note: While a dynamic IP works, static IP or DDNS is strongly recommended for reliable remote access. Without it, your Classic's IP may change, breaking remote connections.

Thank you , I was confused by the ON/OFF under aux 2 on the local app.  Was not sure if it should say ON/ON.

I just looked at Local Status app on my Classic and on the Config / Advanced menu the Aux 2 is set Whizgang Jr  Auto
Scroll down the page and there is section Battery Status Meter  where you set Efficiency  Capacity AH and temp %/C ( look up your batteries and see what they say - it may be the default for that temp setting . And the temperature setting is different that the Temperature compensation setting for charging .

The Whizbang uses Aux 2 so you should have the purple wire from the Whizbang on Aux 2 connection in the Classic. Then yes select Whizbang for Aux 2 . You should see a whizbang junior screen on the MNGP and there is a setup section on there. I think you can do all the same setup in the Local Status app too. It might take a day to go through the cycle to get all your new settings calibrated so the SOC starts working okay .
