Ampy 5235a Electricity Meter

[JonCottPV]

Hi All
Just posted on another thread - https://www.diynot.com/diy/threads/landis-gyr-5235a-red-display.241990/page-2
Type:5235A is listed by OFGEM as 'Faulty' meter for detecting reverse current. Even though it alternates between 'rEd' and numeric display.
I've had a smart/check meter installed and it shows almost zero export.
So it seems it wont export any pv generation to grid.
Is your faulty too?

Happy Days!

just get one of these...

That does not measure energy or watts. It measures current and does take into account voltage or power factor neither of which are constant.
The suppliers are lying.

which specific one are we talking about?

the plug in ones do it the same way that you would with a meter, put the meter in line with the live conductor..

the "wireless" one has a clip on ammeter clamp that plugs into a wireless transmitter..

They don't measure energy or watts either for the same reason.

<various things>

Why are you commenting on 8+ year-old posts?

Kind Regards, John

 

[JonCottPV]

Commenting because:
1. Only just found the thread.
2. Because only just found that I have on eof these meters, installed in 2016.
The meter is blocking export of pv. Presumably it is set to block pv for everyone?

Cheers

As should be apparent from my quote, it was winston's quibbling about 8-year old posts I was talking about, not your recent contributions!

I doubt very much whether any sort of meter could 'block the export of PV' - although, if not functioning (or designed!) correctly it may not be metering the exported energy.

Thanks John. A check/smart meter has been installed which shows virtually zero 'export'. Where is the pv going if its not exported?

If a check meter (assuming it is one that can cope with exports) is indicating no export, then one can but assume that nothing is being exported. If you feel that some energy should be being exported, it sounds as if you may need to have your PV installation checked out.

Thanks John
It came about because I doubled up my pv to max 4kwp last October.
I expected my electric bill to reduce a lot.
But when the first 3mth meter reading showed we had used 70% more than same 3mths previous year I reported what I take to be a faulty meter.
Very strange to try to get to the bottom.
So when I found the meter was mentioned on the internet I followed the links.
Eventually I found that the meter is on OFGEM's list of faulty meters.

Cheers

It is quite possible that a faulty meter would fail to record your export (at all, or correctly).

However, if you now have had a check meter (presumably not faulty) confirm that there is no export, then presumably there is no export? If that's the case, then either you are not generating enough solar electricity to export any, or else something about your PV installation is failing to export electricity when it could/should? Have you had the PV installation checked?

Do you expect a lot of solar generation in the 3 months from October? Apart from anything else, that is a time of year when there aren't all that many hours of daylight, even if it is 'sunny' during those hours.

There is a separate meter for export. AFAIK that is the norm.

I don't know about that as a generalisation, nor about the OP's meter, but, for what it's worth, and although it is not configured for such use (since I don't have PV), my meter certainly has the ability to record both import and export ....

Many thanks.
I'm getting FiT for the original install. There is an 'export' meter attached to the system.
November generation was 52kWh, December 24kWh and Jan 35kWh.
The check/smart meter shows almost nothing on the export register. The import side of the check/smart meter seems to be about the same as the consumption meter.
Curious.

Cheers

As a matter of interest ... that's a total of 111kWh over those 3 months, which would have been enough to supply my electricity needs for about 3½ days. Is it really worth it?
