resting, and requirements to wake ?

[mike90045]

1) I now have an easily documented issue with resting and wake up.   I have 2 arrays of Evergreen panels: 
3Kw South,  on a MorningStar mppt60  (110VDC string), and
2kw SouthEast  on a Classic 200  (160VDC string)   ...

   ...   But it's looking like if I had dropped a panel, and went to 3 strings of 3, instead of 2strings of 5, I'd be ahead of the game, I never thought the MPPT losses would be so high   ...

Alright mike,

I do not mean this as a challenge in any form.
Have been trying to understand the string configuration of your system (I DO have plenty of "corner paint"  of my own,  but this has been nagging at me).

So your 3 KW array is 15 ea  Evergreen 205 PVs (?)  "string voltage 110 V"

The 2 KW array is 10 Evergreen      PVs          "string V  160 V"  --two strings of five.

What is the model number of the PVs in each of these strings?

The only 205-ish STC watt Evergreen PVs that I can find,  have Vmp and Vocs that do not seem to make sense vs what you appear to be running.    Thanks again,   Good Luck,    Vic   

Thanks - no offense.  Had a busy week, long trip, and got a new (2011) Subaru AWD for the ranch. Just now getting back to ya.

Morningstar MPPT-60 panels. 15 panels, 3 strings of 5 panels ("18V")  logs in at about 80V under load, 110V voc 
es-a-205-fa3_18v

The new array is 10 panels "es-e-205-fc3" 35Voc which gives me 162Voc as logged by the Classic 200.

When installed, both strings "agreed" at the same voltage and amps (but I did not write it down.)

Hi Mike,

Thanks for the added info on your system.

Am in transit today ...  more later.   Have Fun.  Thanks,       Vic
