Kodak App Alarm

[Tiaan Vermeulen]

So i wrote to China Shoto and they gave me some kodak settings to use in conjunction with the Shoto batteries. 
I changed it earlier this evening but now I get an alarm, even though the inverters are still working 100%. 
Does anyone know what the below means, and 2ndly how to remove, reset the alarm? Or does it reset by itself?

That doesn't look serious, it is just an alarm that the PV has been disconnected, but it is late in the afternoon so it will be because the sun is setting. My inverter beeps a couple of times in the evening too when PV gets too low. No need to reset the alarm, it will probably reset at sunrise, it shouldn't affect the inverter at all.

Thank you, I thought as much as the inverter was still operating 100% during this alarm notification.

New Alarm this morning? Is there any scripture I can read up about what the different alarm types mean? 

Is there a way to reset the alarm? (unit still functioning as normal)

My Kodak 7.2s constantly report lower battery voltage than true. So, I ignore all those warnings. The only thing you might be able to do is:
- Change setting 25 to disable recording faults, and maybe 18 as well
- Change 29 to a much lower value (assuming your battery BMS is decent, and will shut itself off)
    - I am not sure this will change when the inverter considers the battery "low"

 

The manual has the fault and warning reference:

What settings for the Kodak OG7.2 did Shoto suggest for their batteries?

I'm using 3 x SDC10 box 5 batteries.  Connected in parallel and the RS483 sockets connected.  

'Have not found out the purpose of connecting the RS483 terminals

The voltage measurement of each the batteries, measured with a digital meter, is within 0.1V of the reported reading on the inverter's display

What bothers me is that location 02 is set to Sbu (Solar first) and location 16 set to 16 (Solar first), yet the inverter will not switch to mains charging when there is no sun (ie at night).   

If you have an answer for me, it would help

I did send an email to Segen Solar a few months back, but received no reply

Good morning. 

I only requested a couple of settings from them, and these were the ones:

12- Back to the grid voltage set to 46V

13- Back to the battery voltage set to 53V

26- Optimal Charge voltage set to 56.4V

27- Float charge voltage set to 54.0V

29- Battery Shut off voltage, set to 45V

 

As far as charging goes, we dont use utility to charge. For the time being we have enough storage capacity to make it day to day. 
looking at your settings, Our setting for 01 (which seems to be your 02) is also set to SBU: According to the manual this setting switches over to utility when: "Utility provides power to the loads only when battery voltage drops to either low-level warning voltage or the setting point in program 12."

From the chart above you can see our setting for 12 is 46V. 

To answer your charging question, from my understanding your setting 16 has to be set to CSO-Solar first, which is what you are running at the moment. We use OSO so not the same settings. It's very weird that it doesnt switch to utility charging. In saying that, has your battery actually reached the back to utility cuts off voltage?
