Verifying Overproduction Balance on Landis + Gyr E550 Meter with GSM Module

synology1 61005 42
Best answers

How can I check whether my Landis+Gyr E550 meter with a GSM module is balancing PV overproduction across phases, or only recording import and export for later settlement?

Check the 1.8.0 and 2.8.0 registers and do a simple load test: on a sunny day, turn on a sizable receiver on a different phase than the inverter and watch which counters increase [#15420821][#15422200] If the meter’s 1.8 value increases while total power from the PV system is greater than the household load, then there is no real phase balancing; if 1.8 does not rise, the meter is balancing between phases [#16487173] For semi-annual net metering, the meter itself does not do the settlement — PGE does it later from the collected and returned energy values [#15422200] To be sure, run the test long enough to be visible in kWh, e.g. about an hour, and compare the readings before and after [#15428549] The thread also notes that the E550 can be configured for balancing, but whether it actually does so depends on the meter settings [#15949734][#15947816]

    Hello, I would like to ask people who would like to tell you how to check if the PGE meter balances the overproduction of photovoltaic panels? I have a Landis + Gyr E550 meter with a GSM module, after the net metering input, no one came to me and did not make any changes to the meter, maybe it was done remotely. Therefore, I have a question for people who are deeper than me in the subject, is it possible to easily check whether the counter is balancing the overproduction?
    Thank you in advance for your help.

    Hello,
    I have a similar situation, I think ...
    For me, item 1.8.0 is the energy that flows into the house, and 2.8.0 is the energy that flows into the grid. I have no other information.

    Although these preview items 1.8.0 and 2.8.0 I know, I was hoping that there is another way.

    What do you mean by balancing overproduction? Is the half-yearly energy balancing or temporary energy balancing on all phases? For semi-annual balancing, you do not need to change the meter settings, because you already have collected and returned energy in it, so the balancing will be done not by the meter, but by the PGE settlement center after the end of the half-year, subtracting these values from each other. If you are wondering if you have a momentary balancing on all phases so that you do not have to connect all receivers to the same phase as the inverter, then on a sunny day turn on a larger receiver on a phase other than the inverter and watch which abacuses will increase the indications. The production and the receiver must be quite large so that you can clearly see what the meter is counting.

    Thank you for the specific answer, you explained everything I wanted to know about balancing, so now we pay for the electricity consumed, and after 6 months we collect the surplus.

    Last question: are you sure you have balancing?
    We already have February and this type of settlement should already come, but many people I know (including me) have not received annexes yet and settle accounts on the principles of 2015.

    A very good question, I have a monthly billing period in January I downloaded 424 KWh from PGE (the invoice was issued for that), then I checked according to the meter 2.8.0 and 2.8.10 (end of the billing period of Energa delivered) I had 110 KWh put into the network and I paid for 424KWh yes as if the 110 were not deducted. On the 20th of every month, PGE was paying me to my account for the energy produced. I will have to wait and see if the payment will come in, in January I received a payment from PGE for energy, but in December, theoretically, in February, they should not pay me anymore if balancing will work As for the annex, in February I received and sent back a signed one, but so far they have not sent me back.

    As for balancing, I know from the experience of my clients that Energa and Enea have already adjusted the contracts and are sending annexes.

    As for Tauron and PGE, unfortunately, no one told me anything, so I don't know the details - maybe they have other regulations?

    Edit: I sent a question to the client about the contract with PGE and if I find out something, I will let them know.

    Hello, I followed my colleague's advice and it is not interesting in my case that there is no balancing among the phases, unless I think wrongly. In general, it looks like two inverters, one with a power of 5kW, the other with a power of 3KW. 3KW inverter connected to the phase on the first floor where it serves the receivers from the first floor. 5kW on the inverter Power of approximately 1800W, power per 3KW - 1200W ON PGE METER right arrow P-. I turn on the 2000W pump, the PGE meter shows P + flashing and P- as if I were taking the missing energy from the network. Turn off everything, plug in 3kW inverter to the phase where the pump was connected, similar power on the inverters, only the difference is that P- is lit. Is it possible that there was no balancing among the phases?
    Then, when they installed the meter for me, the installer said that it does not matter which phase it will be taken from, because the meter will balance it anyway, but I think that something is wrong, especially when I tried with the pump. repeats P - ON and P + blinks.

    Hello

    The meters, eg Landis + Gyr E550, work as independent 3 single-phase meters. At the same time, we can send energy to the grid in one phase and download it in another. So at the same time we sell energy for PLN 0.13 (real selling price of 1 kWh) and we buy it in a different phase for PLN 0.01 (average gross price in the daily tariff of 1kWh).
    It will be similar in net metering. Only energy will be balanced on a semi-annual basis, and we will pay for transmission losses and VAT. So if we send the same amount of energy to the grid on one phase, and use the same amount of energy on another, we will pay the difference, i.e. about PLN 0.40 per 1kWh.
    It is known that the energy we produce will be consumed locally by our neighbor, who will also pay for transmission losses. The energy distributor will benefit from this, as thanks to photovoltaic installations it will reduce the variable component of transmission losses, at the same time selling the energy produced by them together with the loss component of "the entire transmission network".

    The best solution is to balance energy before the measurement system, i.e. a 1-phase system.

    Where does this information come from?

    So far, ZE in the vast majority of responses claim that there is phase balancing.

    Unfortunately, I cannot dig to the source, which includes the provision on phase balancing, despite the fact that in several articles on various portals their authors write that phase balancing separately is against the law. I just don't know where to look for such a record.

    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.

    It does not always have to be true - I have a Landis E550 and my meter is temporarily balancing all phases, so I cannot buy 71gr and sell 13gr at the same time. You just have to check it out for yourself. "A bit" is harder to count how it will be before the pv investment, because you do not know what meter you will get ;-)

    When installing the Landis + Gyr E550 meter with a GSM module in February, the installer said that the meter does the balancing every 15 minutes. A letter has arrived today to send the Q1 report.

    Added after 59 [minutes]:

    Do you use eCounter in Tauron? I cannot create an account, he writes:
    "We are sorry, registration to the TAURON eLicznik system is not possible. There is no remote reading energy meter installed in your home, business (or garage). "

    eCounter after the exchange of messages, has been started, I have a preview via eCounter in Tauron.
    You can see how it balances how solar 0 consumption is, and how much is sent in overproduction.

    I have started the remote counter from the beginning of June (I have readings from the beginning of the installation of the counter). Each photovoltaic meter will work remotely. Therefore, they mount a GSM module to the meter. But we had to ask about this counter so that they could configure it.

    what do you mean by "you had to ask about this counter so that they could configure it."

    Today, the same meter has been installed at my place, I would like to be able to read the data remotely. Unfortunately, on the website ebok.gkpge.pl there is no such possibility.

    Two months ago, I sent an official letter to PGE Dystrybucja in Rzeszów on this matter. VERY KINDLY, they replied that they made this data available only to PGE Obrót, and I could read the meter registers "with my eyes" and they sent me instructions on what registers mean and what to press to read them.

    Hello, the topic about balancing, so I will step on it. In July I had a gamma 300 meter installed and after a month of complaints from PGE, Rzeszów admitted that this meter does not have inter-phase balancing and they replaced it with Landis 550 today and from what I see it behaves like its predecessor, i.e. I take one phase for the other two - at least that's what the graphical indicator of the counter shows. As sunlight increases, it switches to sending. Does any of the users have such a counter and can confirm that this counter has balancing?

    Sends every 15 minutes, but the counter option is set to 15 minutes for balancing. These were the installer's assurances. The meter was still checking connected to the computer, even though he did the configurations in the company.

    Are you sure balancing is every 15 minutes. If this were the case, the counter would have to show and save the status every 15 minutes, otherwise it would differ between what the counter counts and what it sends. If, for the sake of simplicity, the installation produces 3 kw within 15 minutes (i.e. 1 kw per phase) and I use 3 kw (on one phase) and if the meter actually reads only every 15 minutes, it is correct, but if it counts on the current one, and so it should be this will show in 15 minutes that I took 2 kw and produced 2 kw and then after 15 minutes it will reset the counter.

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$, post #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$, post #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, post #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?

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

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]
