Need help. CLassic 200 do not waking up.

[trigrong]

Hello,

My Classic 200 was working fine for last several months and couple days ago it stopped charging batteries.  The green lamp flashing at sunny days and no charging at all. I tested the voltage from solar array - 170 volts going into Classic but no charging going on.  I turned off/on cables, reset firmware to factory - did not help.  Can anybody help me - what the problem could be?

Thank you!

As I pointed out in my Email, please use a volt meter and check the actual voltage on the blue terminal block in the classic from PV+ to negative and from Battery+ to negative. Try to watch the PV voltage for say 2-3 minutes and see how stable it is. Not the range it is fluctuating that may help.

Also what serial# is it (Roughly if you do not want to give the actual number)

Hello Ryan,

I'm out of my house but I asked my friend to measure voltage.  He says that PV voltage changes from 152 to 160 volts and he hears some sound like a rely  switches.  The gel batteries stays at 20 volts. I'll be there in couple of days and will be able to connect my computer to the device and look at app software. As well, I'll give serial number.

trigrong;

I have to ask what voltage are the batteries supposed to be?

20 volts sounds very low for a 24 volt bank and very high for 12 volt?

At that voltage the Classic may not fire up because it doesn't see a valid voltage on the batteries? I am not sure on that but is my first thought early in the day.

24 volts.  Nothing was changed in configuration.  It worked for several months and suddenly stopped - that is why batteries out of charge. I can try to charge batteries and try but I doubt it could be a reason.

If your 24 volt batteries are at 20 volts, they are dead.  They probably can't be recovered

no, it's GEL batteries.  Replaced two batteries in array and with 23.9 volts it still doesn't work.

So to confirm this is a Classic 200 LITE correct? It will be good to see if the Local App provides a reason for resting. There will be a number in front of the resting on the local app this may help us.

Ryan

[trigrong]

Yes, this is Classic 200 Lite.  Tomorrow will be at home and try to connect via Local App to see the reason.

Thank you!

I stuck in a deep snow and got to the home at sunset but still, it was 100 Volts. The local App said Status - 1 Resting (Low Light). I suppose same was at day when it got 160 Volts.  Any thoughts?

Is there any shading at all on the panels?

[Halfcrazy]

What we need to do is take a digital volt meter and place the probes on PV+ and Negative on the blue terminal block on the classic. Every 90 seconds it should try to turn on and that voltage should dip. If it is dipping say 10 volts or more it is assuming there is not enough power to run and this sort of indicates either hard shading or a loose wire connection somewhere. RFR1 will likely not be a fault in the classic as it has to try to turn on and see the PV voltage fall to much to throw a RFR1

Thank you for information!
Yes, two of the 10 panels has been covered by layer of snow.  Is that could be a problem?

[Westbranch]

YES, Snow on panels =no sun on panels = no power from panels. 

You need to get all of the snow off the panels.  Any small patches of snow will greatly diminish the output of the panels, the same effect as shade!  Use a broom with soft bristles.

If you can change the angle of the PV mount it is best to have the PV's as VERTICAL as possible to shed the snow without someone being there.

Please try changing the mode from "SOLAR" to "Legacy P&O" and see if that helps it get going.
