Ok the issue with addressing the classics using the local app is it does not address the MNGP. You dont want to use the local app for addressing on classics only classic lites.


and this

Actually to address the classic is done from the home screen. On page 21 of this manual

http://www.midnitesolar.com/pdfs/Classic_ClassicSL_Manual_10-001-1_REV_L.pdf

To address a Classic simply use the MNGP that is plugged into that Classicor plug the MNGP into that Classic and hold the LEFT ARROW keydown and tap the UP or DOWN ARROW key. The normal default address is 10 so going up will take you to 11 and down to 9. When you get to the unused address you want for that Classic, hold the LEFT and RIGHT ARROW keys for a second until “Data Sent and Saved” shows up. Now this Classic has been re-addressed to the new address.

Take a look at this - was a bit different question about SMA but I think the same principle applies to your situation.

I think maybe there are two addresses to set . There was just a discussion about this recently - I will see if I can find it.

It was something I did when I changed the modus address from 10 to 9 and 8 respectively. I think the MNGP couldn't talk to the classic anymore.

Hmm, I did when I was here last weekend. I changed the mod buss address. They were all at the same address. Was that bad?

Got comm is just communication between controller and MNGP I believe. It shouldn't effect the Classics operation.
I have never seen any issues while using MQTT.
Did you change any of the Classic addresses ?

I think they contributed power today but does anyone know if they will charge the batteries in this state?

I just got up to my place today and 2/3 controllers are saying Got Comm. I think the MQQT script has something to do with this.

New Product Ideas and Discussion / Re: New Off Grid Inverter Charger

Nice to hear you are working hard on this! If you guys ever need an average joe, fumble fingered, do-it-yourselfer with poor eyesight, and hearing - I'm your guy. There are so many 'common knowledge,''rules of thumb' and such that your first time DIYer aren't going to have. Often a manual that reads perfectly well to the EE, or knowledgable sales people, may read like 5 dimensional chess to the novice - perhaps a 'for dummies' (but don't call it that) version of the manual that leaves out all the tasty goodies the techs love, but puts in all the stuff that you already know so deep down that you can't even imagine someone else not knowing. I'm in the middle of building a house of my own design, no experience or anything like that. I can buy a book (or watch a video) that shows me how to do most of what I've done, but they don't tell me the stuff that any half-decent carpenter's (electrician's, plumber's) helper knows - I've had to overcome some serious errors because of this. Now I know printing a 2nd version would cost twice as much, but in this digital age a 2nd version shouldn't cost much more than the cost of writing it. Just my thoughts. Keep up the good work.

E Panel's, Disconnect Boxes and Breakers / Re: How do you test a DC shunt?

« Last post by Trukinbear on October 18, 2020, 01:07:17 PM »

Yeah, way heavier than the Heart, and the Trace units it replaced. Since this heavy sucker went on the backplate before the E-panel I'm not sure it will even come off without uninstalling the E-panel. Does anyone have experience like that with the MNSMA-short backplate, and MNSMA-OG E-panel - will I have to take it all down to replace my inverter?
