Can I see as setup some parameters (e.g. Limit for Over/under voltage AC output, limits for over/under frequency, adress for modul for RS485 etc.)? As I can check it? Can I see it from PC or only on local display?
Thanks for answer.

Low production on new 3k omnik

Hopefully someone can help me with my problem. I just had a 14 panel 240 Wp system iinstalled (3,36kWp) with the Omnik 3k inverter. I'm quite new to solar energy etc but I think there is something not wright with the system because yesterday in the full sun with no clouds it only generated 1,5 kW. On average if a I compare my system (same kWP and city ofcourse) I only produce half of what other comparable systems are producing. I understand that probably there will be sleight deviations between systems but only half the production seems al lot to me actually. Does anyone have a idea of what could be wrong if anything? Also on the Omnik portal Ican see that on the input side PV1 gives a voltage but PV2 does not. I asked my installer but they told me ther was no voltage on the PV2 because we have a one phase group installed in our home and not a three phase group. But I think PV1 and PV2 are the input from the panels to the inverter if I'm right and should both read out a voltage? Many thanks for your reactions.

What purpose left meter?

Hi!

Can anyone tell me the purpose of the left meter? It displays the current power but the meter always only shows one marker green? Would make sense when it showed markers which indicated power opposed to installed capacity?

Thanks!

Hello,

When i woke up tomorrow en checked my omnikportal it told me there was already generated 7.5kwh.
But thats not right and now my stats are not OK.

The monthly stats en yearly stats are now almost 10kwh higher than the total energy. I hope you can fix this?

add encryption to open access point on Omnik wifikit (security mode)

June 4, 2013, 6:43 am

hello,

I have an (internal) wifikit in my Omnik 3.0 inverter, but there is a security problem with it. Hacking the access point and then my own home network is very easy:
1. hackers can log in on the unencrypted access point and then login with the default passwords (admin/admin)
2. hackers can then click on "show key" to see the WPA2 encryption password of my own WPA2 protected home network.
3. after that hackers can gain access to my own homenetwork with my PC's, NAS's and other devices.
4. This is very unsecure Confused

Changing the default passwords of the internal webserver is not sufficient, as the access point is unencrypted and the passwords can be "sniffed" very easily (due to the case that there is no encryption).

I have tried this with the access point of my own inverter and I could hack it within 30 seconds and hack my own wifi home network within 60 seconds.

The wifi access point ("AP_6023xxx") is unencrypted and the current firmware does not support encryption. I have tried to add encryption, as decribed in this document: http://www.omnik-solar.com/faq/attachment.php?aid=15

However "http://10.10.100.254/m2m/ap_config.asp" does not exist. It says "404 file not found". So i can not add encryption to the open access point of the inverter.

I have internal wifi card with version 6023xxxxxx and firmware version is 4.01.9d1.

Is it supported to add WPA2 encryption to the internal wifikit? Or do I have to exchange the internal wifikit for an external kit with ethernet connector (and disable wifi)?

Hope that someone has an answer to this.

Hi,

on the monitoring website, the AC output of my PV2 port is 0, while the DC input is 165 volt.

Is this normal?

DC1 = PV1 from 360 to Zero

Why why, just like that......Angry

Reliability? that's the question
Are the Omniksol's reliable?

Mine PV1 gave up, out of the blue, and it is not the first time.....
To bad, but somehow it effects the other string as well??

because you expect: at least i have half the power when one string out of 2 is giving up......no way, a quarter is the best omniksol 4.0 TL can do.

See time and date of death.....RIP PV1Angel
Is there a fuse inside? that might be triggered or malfunction???

Any idea'sHuh

Max. power installed versus peak power

I have recently installed 3.75 kWp (15 *250 kWp) at omnik 4.0k-TL.
Tracks 8 and 7 pieces.
My recorded peak power recorded (Pac) = 4.26 kW and Iac= 17.7 Amp.
Can anyone explain?
Is the power Pac the net delivery into my home grit?

Ps:The noted efficiency is 4.12 kWh/kW/day over the last 40 days

Is it possible to automatically download the data from the portal site using i.e. the wget utility.

for instance wget http://portal/xxx.cgi?userid=?password=?site=?reporttype=

and get a csv file same as the export function gives.

Temperature inverter and string voltage versus efficiency

June 6, 2013, 10:06 pm
$

Is there data available on the efficiency of the inverter (esp. the 3k version) as a function of:
1. temperature of inverter (does it become less efficient if it becomes warmer, eg would it make sense to cool it with an extra fan or shift it to a cooler place)

2. string voltage: in the leaflet it shows 400, 360 and 330 volt (with max eff. at 360 volt), but what is the efficiency on 250, 200, 150 volt? Solar degisn doesn't seem to take the efficiencies in consideration (based on some trails)

Thanks

Strange spikes on completely sunny day?

Hi all,

Today it was a clear blue sky all day, but somehow there are multiple power spikes showing in the monitoring report (see picture below).

Is this normal? I can imagine that on cloudy days, the output differs.... But today was completely sunny, without any clouds!

I have 12 PV's on the south and without any shadow.

Hope someone has an answer.

WiFi Cause Inverter failure?

June 9, 2013, 7:09 pm

So far I've got my 4th inverter. The previous three all broke down. For all of them, one of both DC channels failed. There was no error logged.
The system has been checked by the installer, but they couldn't find anything wrong.
The system has 2 strings of 11 panels totaling 4290 Wp (2145 per string)
My Neighbours have exactly the same installation. They have had no problem with their system.

The only difference that I could find is that my DC wires come from the right side of the inverter, cross the WiFi antenna and are then connected to the inverter (see photo). At my neighbours site, the DC wires come from the left side of the inverter and are not crossing the WiFi antenna.

It seems far fetched but is it possible that the WiFi antenna interferes with the DC leads and could cause the inverter to break down?
