The "Classic" charge controller / Re: more solar panels that I thought possible. Time to expand

« Last post by Vic on September 20, 2019, 07:27:29 PM »

Hi Mike,

Follow Me coordinates the transition to Float,  the transition to EQ,  for the following Classic,   but IIRC,   the transition TO Absorb  is still done individually,   but that should not be a problem.   The following,   describes a Master/Slave configuration for  Classics FollowMe:

Because the WvJr Shunt is in the negative lead of the battery,   the Classic with the WB  measures the total current into and out of the battery,   and is visible on that CLassics MNGP,   and on the Local App.   No wagon upset.

Sorry to hear of your GT system issues.

Good Luck,  Vic

Vic,

Kinda what I figured.

Now I take it the first classic decides when the battery is fully charge and, tells the other classic that it needs to change from absorb to float at the same time, too.
THAT being said, if the first classic has a WBjr installed, then adding a second classic won't that upset the wagon?

This might be a project for next spring 'cause the problems with my grid tie are continually mounting.

Barcelona / How Does Barcelona Sense Vbat?

« Last post by Vic on September 20, 2019, 01:57:37 PM »

The Barcelona is looking great,   thanks onanparts for all the pics.

But,  how does Barcelona sense battery voltage,   have not yet seen the terminals for battery voltage sense (Kelvin terminals) ??

Will Barcelona need an added widget to do this (a communication accessory) ??

Sure do hope to see a close-in ship date,   soon.   She is looking quite finished,   very nice work,  MidNite !

Thanks for any info,   Vic

Robin showing Baxter, a MS Engineer, how fast he can remove the cover of a Barcelona!

The "Classic" charge controller / Re: more solar panels that I thought possible. Time to expand

   ...   "So as I understand it, I can't parallel another Classic 150, but it has to be by itself. Does That means I have to run another cable from the array, (more panels not connected to the ones up there now)  OR... can I parallel all the strings of the panels into one cable to feed two Classics?
OR... must the array be split into two different arrays to feed each classic?

Then do I use the follow me feature to charge the same battery bank with the two controllers?

thanks...

Mike,

YES   each Classic  MUST have its own separate array.  So you will need two additional cables.

You will need Combiners when you have three strings or more (or if you have three or more PVs in parallel).

The larger MN COombiners,   like the MNPV12 have dual Positive Buss bars,   that can be used separately.

And,   YES,  running multiple  Classics in Follow Me  is the best way to handle multiple  CCs on a single battery.

FWIW,   73,   GL.   Vic

The Rosie / Re: Is there any expected release date

« Last post by onanparts on September 20, 2019, 01:01:11 PM »

Caught boB getting a Rosie ready for the SPI show yesterday. The Rosie is going to be a very nice inverter! Good to see her in real metal castings and all the internal goodies! As boB stated, not ready for prime time but she is getting closer to being turned loose. More pics coming soon!

The "Classic" charge controller / more solar panels that I thought possible. Time to expand

« Last post by qrper on September 20, 2019, 12:41:21 PM »

I never thought that I'd have more solar panels than I needed. Long story short, I purchased 40-250 W panels for a grid tie system. Seems the panels I purchased did NOT come with the UL, CSA, or ETL labels. According to the electrical inspector, he won't pass the system with those panels...GRRRRRR!!!

I used some of them to replace the old Solar MSX64s. the new panels quickly maxed out the Classic 150.

So as I understand it, I can't parallel another Classic 150, but it has to be by itself. Does That means I have to run another cable from the array, (more panels not connected to the ones up there now)  OR... can I parallel all the strings of the panels into one cable to feed two Classics?
OR... must the array be split into two different arrays to feed each classic?

Then do I use the follow me feature to charge the same battery bank with the two controllers?

thanks...
