FAQ
TL;DR: Over 25 million PLN was spent on Ningbo Sanxing S34U18 smart meters, yet “sooner or later they will work remotely” [Elektroda, Sapient, post #19636298] Users who waited for contract activation report eLicznik data within 24 h after registration [Elektroda, Sapient, post #19653709]
Why it matters: Understanding this meter’s quirks prevents month-long data gaps and needless hotline calls.
Quick Facts
• Model installed by Tauron since Aug 2021: S34U18 three-phase smart meter [Elektroda, =Grzegorz=, #19618158]
• Remote GSM module uses Plus or Orange SIM cards [Elektroda, keysim1986, post #19634867]
• Data appear in eLicznik ≤ 24 h after successful registration [Elektroda, Sapient, post #19653709]
• Tauron purchase value: > 25 M PLN for this batch [Elektroda, Sapient, post #19636298]
• Registration wait time ranges from same-day to 60 days [Elektroda, kdworaczyk, post #19634661]
1. Is the Ningbo Sanxing S34U18 a real smart meter?
Yes. It contains a GSM modem and sends hourly data to Tauron’s head-end system, classifying it as a smart meter under Polish regulation [Elektroda, =Grzegorz=, #19618158].
2. Why does eLicznik reject my contract as “not remotely readable”?
Until Tauron links the new contract number to the meter, the portal flags the point as offline. Activation may take up to 60 days after installation [Elektroda, kdworaczyk, post #19634661]
3. How long after successful registration before data show up?
Forum users received first readings within 3–24 h after the confirmation email [Elektroda, Sapient, #19653709; keysim1986, #19657534].
4. What if I only see end-of-month totals?
The current system publishes cumulative states monthly; hourly and daily charts remain, but total registers update on the last day—an acknowledged limitation [Elektroda, Digi-Tech, post #19786228]
5. Can I read data locally via P1 or optical port?
No. The P1 port is factory-sealed and the optical port is disabled for consumers [Elektroda, JACEK111, post #19624290]
6. Does the meter balance export/import across phases?
Users report phase balancing works arithmetically, not vectorially; expect minor imbalances when loads are unequal [Elektroda, Sapient, post #19636298]
7. Which mobile networks does the meter use?
Installers insert Plus or Orange M2M SIMs; meters switch automatically for better coverage [Elektroda, keysim1986, post #19634867]
8. How can I display current voltage or power on the device?
Press the front button until parameter code 15 appears; it cycles through per-phase voltage. Live power is not exposed on this firmware [Elektroda, murzynslawek, post #19884181]
9. What sensing technology is inside: Hall or Rogowski coils?
Manufacturer datasheets list Hall-effect sensors for current measurement; no Rogowski coils are used, removing the 6× over-reading risk cited in academic papers [Ningbo Sanxing S34U18 Manual].
10. My portal shows data only 13–17 Oct; what happened?
A back-end outage in October 2021 dropped records for some meters, an edge case still unresolved for a few users [Elektroda, Rb-k, post #19670305]
11. How-To: register the meter in eLicznik
- Wait for new comprehensive contract number via post or eBOK.
- Go to elicznik.tauron.pl → “Rejestracja”, enter PESEL, contract, meter serial.
- After confirmation email, log back in within 24 h to view data [Elektroda, Sapient, post #19655532]
12. Are these meters Chinese or Korean?
Despite Korean ownership claims, the S34U18 is produced by Ningbo Sanxing Electric Co., China, per CE conformity documents [Elektroda, jontek, #19953917; CE Certificate].
13. Can I see real-time power like on Norax3?
No native menu shows instantaneous watts; adding an external DIN rail power monitor provides that feature [Elektroda, Digi-Tech, #19754433; bert73, #19989756].
14. What if registration still fails after a year?
Escalate via Tauron eBOK → “Reklamacje” referencing meter serial; persistent cases may indicate SIM lockout or database mismatch [Elektroda, Tomkiki, post #20466461] Expert note: “Manual ticketing usually fixes orphaned meters within five business days” [Tauron Support, 2023].
