DIN rail meters

[BruceB]

I have been asked to put pv on a new build house. Rather than add another box on the wall it would be neater to put a din rail total generation meter in the consumer unit. Anyone done that and/or used one of these?

Bruce - there are a few DIN-rail mount generation meters available as far as I am aware although they are not commonly fitted. The PRO75 is one, the PRO1 is another. They are both available with either an analogue or digital display. Both these meters are manufactured by Inepro and are available through a number of resellers. We can offer the PRO75D ourselves but can source whatever you decide you require if you need assistance. Inepro also make a 3-phase version called PRO1250.

Did you end up fitting a DIN rail mounted meter? I have a similar request and wanted to know whether it is acceptable for the generation meter to be only MID certified, or does it also need to be OFGEM approved.

Not yet but I have 3 installs where I am lined up to use them. I did speak with the manufacturer (Rayleigh) and confirmed that they were now certified and suitable for billing applications. I also suggested they get them into the larger wholesalers as an option.

We are looking at using the Enerdis MEM03-M, this is MID certified as well. The UK supplier have a minimum order of 6 units so I would be interested to hear of any wholesalers selling individual units. Having said that, it would make for a neater installation with the meter integrated into the CU so I may be tempted to install these where room exists in the CU or when installing a new CU. My main concern is around cost as these are probably more expensive than the usual meters we use.

Whatever type of DIN Rail Meter you choose, be wary of the digital type, my company now fits Landis and Gyr E110 (non- DIN Type)instead of the previously used ABB OD1365. It's not really a DIN issue but the ABB meter also showed polarity by means of clockwise rotation arrows on the display (which meant correct polarity). At night time when the panels stopped producing, this meter would show an error code and the arrows would rotate backwards, probably due to the invertor taking a small amount of supply from the AC supply, even when it is waiting for DC supply. This then led to customers complaining when there wasn't actually an 'error', just a meter that gave too much information. After all, most people who have microgeneration systems newly fitted will often stand and stare at their meter as this is the only proof of a healthy install they have that their knowledge allows them to understand. This is another factor worth considering because if you're run off your feet doing these jobs, you may not have time to then go on 2nd visits to exchange meters for simplified versions.
