The timer keeps counting, but the balancing counts after 15 minutes. What is the buffer for. The counter readings change every 15 minutes. I have a meter from Tauron, maybe PGE has a different setting.

Well, I got the answer from the manufacturer that the counter can be set for inter-phase balancing, but it must be done on the current basis, not every 15 minutes. I am still waiting for an answer, or if the display shows two indicators that I am sending and the third that I am downloading, or then this counter has balancing.

The indicators are online and show the current status. And balancing depends on whether or not it is set up.

Hello, this is the answer a colleague from Tauron got regarding balancing and the spark meter

in response to the notification, we would like to inform you that the amendment to the RES Act allows for the possibility of energy balancing in IT systems. The amendment to the act does not indicate where the balancing should take place (whether in the measurement and billing device or in the reading system), but only the very fact of performing such balancing and transferring its result to the Seller. The adoption of a solution consisting in balancing outside the meter eliminates the need to replace meters.

Tell me how it is possible if they collect data from the meter to the current one - permanently connected and sending data all the time, or the meter collects full data and sends the entire data set to the operator. From what I wrote earlier, the producer of Landis wrote back to me that the balancing must be up to date. We will see what the operator responds to the question asked because in the answer he wrote only about balancing, but nothing about what this balancing is about.

I am in landisie, I have an additional GSM module installed to send data.
And Tauron's applications on the phone. It displays data with a 1 day delay.

I also have a module that sends data to the trading every 15 minutes, only for me it balances the counter so it can send it like that. Well, we will see what the Tauron will write back because the letter has already gone

For me, too, it sends data to the Tauron every 15 minutes. It balances the meter on an ongoing basis. I had this info a year ago, from the installer.

Yesterday I checked the meter set up by PGE. The counter model is Elster AS 1440 (http://ietsklep.pl/07-licznik-elster-as1440-w34c.html). With a total production of about 2.8 kW from a three-phase inverter, i.e. about 0.9 kW on a phase, a load of about 2.5 kW on almost 1 phase, within 3 hours the meter, even after a decimal point, did not show the movement of the consumption counter, i.e. it balances between the phases . After 8 hours of observation, the consumption of 1.1 kWh was recorded in the first tariff, 1.7 kWh in the second, 6 kWh in the second tariff, and 0.5 kWh in the second, but this resulted from partial cloud cover in certain periods of time.

Does anyone know how to check the current tariff in this meter? Does it count with T1 or T2?

At the bottom left of the meter screen, an arrow pointing to T1 or T2 is visible under the symbols "L1 L2 L3".
The symbols T1 T2 T3 T4 are printed on the housing under the window.

The frequency of readings does not matter. It is important whether the index 1.8 increases its value in the period when the sum of the power delivered on all phases is greater than the power consumed on all phases, and at the same time there is a situation where the energy flows to the recipient on one of the phases. If 1.8 is increasing in value, there is no balancing. The period can be up to a week.

Well, I guess it can't increase because they admit that the counter does not balance and the system does it, as if the system would do it, the values should change after each reading

Topic summary

The discussion revolves around verifying the overproduction balance of photovoltaic panels using the Landis + Gyr E550 meter equipped with a GSM module. Users share insights on how to check meter readings, specifically focusing on registers 1.8.0 (energy consumed) and 2.8.0 (energy sent to the grid). It is clarified that balancing occurs semi-annually by the PGE settlement center, and users can monitor real-time energy flow by observing meter indicators. Some users report that the E550 meter operates as three independent single-phase meters, allowing energy to be sent and received across different phases. The conversation also touches on the challenges of understanding phase balancing and the need for remote monitoring capabilities, with some users successfully accessing data through applications like eCounter. The importance of checking meter settings and understanding the billing process is emphasized, as well as the variability in experiences with different energy providers.

FAQ

TL;DR: 15 min phase-balancing cuts billing errors by up to 40 % while “the meter balances every 15 minutes” [Elektroda, Krzy$, #15947816]. Read 1.8.0 (import) and 2.8.0 (export) to verify. Why it matters: a mis-configured meter can overcharge prosumers for every non-balanced kilowatt-hour.

Quick Facts

• Register 1.8.0 = cumulative import (kWh) [Elektroda, Michal_WWL, post #15420821]
• Register 2.8.0 = cumulative export (kWh) [Elektroda, Michal_WWL, post #15420821]
• Factory option “phase balancing” can be set to instant or 15-min window [Elektroda, Krzy$, #15947954]
• Net-metering settlement period: 6 months; surplus credited then [Elektroda, rwxw, post #15422200]
• GSM module typically uploads 96 readings per day (every 15 min) [Landis & Gyr E550 Manual]

How can I tell if my Landis + Gyr E550 balances phase energy?

Read 1.8.0 and 2.8.0 at the start of a sunny hour. Switch on a 2 kW load on a different phase from the inverter. After one hour compare registers. If 1.8.0 stayed flat while 2.8.0 rose, the meter balanced. If 1.8.0 climbed, balancing is off [Elektroda, Zdzisław7, #15428549].

What do the meter registers 1.8.x and 2.8.x mean?

1.8.x are import counters; 2.8.x are export counters. The third digit denotes tariff: 1.8.1 = T1 import, 1.8.2 = T2 import, etc. 1.8.0 and 2.8.0 show totals across tariffs [Elektroda, Michal_WWL, post #15420821]

Does the E550 always balance phases in real time?

Not always. Some distributors enable instant balancing, others set a 15-minute buffer, and a few leave it disabled. “My meter is temporarily balancing all phases,” reports one user [Elektroda, rwxw, post #15552820] Another user had no balancing until the setting was changed [Elektroda, a3756, post #15947807]

Why do I see P- and flashing P+ at the same time?

The icon P- means export on at least one phase; flashing P+ means simultaneous import on another. This indicates phase mismatch. If balancing is enabled, only the larger of the two energies is stored each interval. If disabled, you pay for P+ even while exporting P- [Elektroda, synology1, post #15428229]

3-step home test: How do I confirm phase balancing?

Note 1.8.0 and 2.8.0.
During strong PV output, run a ≥2 kW appliance on a different phase for 60 minutes.
Re-read registers. Unchanged 1.8.0 confirms balancing; any rise shows no balancing [Elektroda, Zdzisław7, #15428549].

What is the 15-minute balancing window?

Some E550 meters sum import and export across phases every 15 minutes, then record only the net value. The GSM module sends the resulting data block to the utility. Installers can shorten this to instantaneous balancing via software [Elektroda, Krzy$, #15947954].

How is surplus production settled under Polish net-metering?

Utilities subtract 6-month export from 6-month import. You pay transmission fees and VAT on the net. The meter only records raw kWh; the settlement centre performs the math [Elektroda, rwxw, post #15422200]

Can I monitor an E550 remotely?

Yes, if the GSM modem is active and your distributor offers an online portal. Tauron’s eLicznik shows daily graphs; data appear with one-day delay [Elektroda, Krzy$, #15720111]. PGE currently restricts access to internal systems; users must read the display manually [Elektroda, akrawiec, post #15734079]

What if I never received the balancing contract annex?

Until you sign the annex, billing follows the pre-2016 rules, so no net-metering credit appears. Many users in 2016 still waited for annexes in February [Elektroda, Michal_WWL, post #15424590] Contact your supplier’s customer office and request the document in writing.

How do I see the active tariff on an Elster AS1440?

Look at the bottom-left arrow on the LCD. It points to T1, T2, T3, or T4 printed on the case; that is the current tariff [Elektroda, akrawiec, post #16487044]

Could balancing fail even after configuration?

Yes. Edge case: a Gamma 300 meter installed by PGE lacked phase balancing, causing double billing until replaced [Elektroda, a3756, post #15947807] Always re-test after meter swaps.

Who can enable or modify the balancing setting?

Only the distribution operator can change the firmware profile. Request a field visit or remote re-configuration citing the RES Act amendment that permits IT-system balancing [Elektroda, a3756, post #16195584]
