Power peak dashboard, Max. instantaneous power1.6.5.3

[febpro]

Hi
my system is
System: raspberrypi
Software: 123Solar 1.6.5.3 and
Reader: SMAspot 2.0.6a
Device Type: SB4000TL-21

I upgraded from 1.6.0 to 1.6.5.3
because I was hoping to solve this problem

1) question
Power peak 0,0W, today 0,0W

Alarms/Warnings checked at 11:59
R.iso. 0,00Mohm - iLeak 0,0mA

2) question
yesterday and other days
in page index_mono.php

Max. instantaneous power
1546879 W @ 6:38
1546879 is example, but the value was not correct

thank you for help

ciao Fabio

Hi,

SMAspot don't return (or your inverter) Power peak of all time, Power peak of today, R.iso and I leak. Hence why they are set to zero

For the "Max. instantaneous power" there is obviously a problem, this value is catched by 123s. I'am not aware or people running 1.6.5.x with SMAspot 2.0.6a yet.
I'll take a look tomorrow on your logger if i find something. Is the live value correct ? Is it a triphased inverter ?

So far, i don't see a problem for now: Max. instantaneous power 595 W @ 09:08

Hi
thank you for info SMAspot
I work with 2.06a; you need to upgrade?

"Max. instantaneous power"
now is OK
I think bug occurs at power on or off inverter

so far, I have seen at power on, but
I've seen bugs last night
a) yesterday OK peak at 14 .. 15 is OK
b) when inverter is turned off -> 128760 (example)
c) next at 20 - 21 -> 0 !

Well, maybe it's SMAspot or the inverter who return wrong data.
AFAIK, the 123s output is not implemented in current release for SMAspot. It should be available later on as well as multi-inverters support.
Alain (aldesr) he's in touch with the guy of SMAspot, you better ask on their forum as I am not aware of the current development.

now 123solar is in error
Max. instantaneous power
350432 W @ 06:41

Yup, i see it. But, it don't mean the error is from 123s
My take: is that your inverter or SMAspot report wrongs values. It happen with aurora as well, but that's the inverter who report wrong datas. There is nothing much i can do for that..

If you want to test, run SMAspot alone for a day or two and check if the values of grid power are sometime inaccurates.. Or ask on their forum if it has been notified.

Fabio, the kind of values you report would make me think of the missing spot values calculation problem Luc (SBF) referred to in the SMAspot forum.

Luc forgot to scale inverter raw values before doing the maths => Pac are sometimes 100000x when inverters start to produce.

Try first to disable the option in SMAspot inverter cfg file, as he suggested.
