Voltage drop, low charge power

[Jose Miranda]

Thanks boB. I'll check the versions when I get home.

Oh, Just heard from Andrew...  There IS a siren sound in Chatty-Kathy audio mode that will come up some times.  He needed to fill one of those
sounds with something temporarily.

If it is this that is causing that sound and you don't want to hear it, go to the MISC menu.  Then AUDIO menu (or SOUND ?)
and change from Chatty-Kathy to VERBOSE maybe ?  You can also turn it OFF if you like which should be  RICK MODE.

I think that RICK MODE will only make noise when there is an error that you will want to know about.  No sirens or
alarms that I know of.  The siren you heard MAY have been a Star Trek type sound ?

boB -
I don't mind all the silly sounds and  voices talking - kind of funny. I just wish there was a one button solution like Enter - to mute them - like if I am on the phone and they start talking  --it is really hard to shut them off without a lot of button pushing.

It was in Rick Mode.

Jose, can you please look at the revision and date of the MNGP code ?

Just press STATUS several times until you get that information screen.

Maybe the Classic rev too but mainly the MNGP rev.

We have revised the MNGP code a time or two to help with this alarm noise issue but I thought that
it only happened when the ENTER button was pressed in the main STATUS menu.  Maybe there was
a version that had some randomness to this noise ?  I have alerted the engineer about this thread.

Thanks,
boB

MNGP: 2186
Classic: 2126

I think I have an outdated firmware... Should I upgrade it?

[Westbranch]

Yes, sorry but I cant locate the list of matching F W versions to  MNGP Version...

[boB]

No, I don't think there is a new version YET.   This must be a bug.

I really like the idea for a MUTE button !

Any news on the low power yet ?

The electrician is coming tomorrow during the afternoon. I will let you know.

What do you mean with a bug? That the Classic has a bug in the current firmware that shows the wrong version number?

No, just that you heard a noise when it was set to Rick Mode.   i.e.  It should have been quiet ?

Problem solved!

The negative and ground PV wires were inverted. The electrician noticed the error and swapped them, and it is working correctly now! Thanks for the help!

[boB]

WoW !  Interesting issue !  Have never heard of that one before !

Thank you Jose for letting us know.

Carry on....

jose miranda,
i want to know who was inverting those wires.

[FNG]

When the PV is in overcast conditions the classic will drag the voltage down more than normal to find the maximum current output in amps out of the array,

With 3 modules running around 120 volts open circuit when it is in ideal conditions and in bulk mppt I would expect about 96 volts.
