Reverse Run Symbol on my Aclara smart meter - related to my solar panel export?

Hi @mboursnell ,

Actually, that doesn’t look like the real Reverse Run symbol. I can see from your photo that your meter appears to be currently tracking legitimate exports. However, it might be the version of the user manual I’ve got could be outdated. I’ll ask a few people for help there, such as the legendary @Lukepeniket_OVO . Just to be sure!

OK, thanks. I’ve checked again and it appears to have vanished. I don’t know what that means. It difficult to find a really good manual for the meter…

Hehehe, that’s where my tricks come into play!

Here you go. https://www.smartme.co.uk/documents/Aclara-SMETS2-Single-Phase-Electric.pdf

That’s the entire user manual for the Aclara SGM1400 Series, which is the type you’ve got. It’s a bit technical, but should answer almost everything you need to know. If you get stuck, I can also try to help or summon Luke if I get stumped.

The fact the symbol has gone off and the fact you’re now Importing rather than exporting confirms my suspicions. That particular symbol only lights up during legitimate exports. If you had triggered Reverse Run, it would have stayed there until it was reset via SMETS Commands.

Yes I’ve seen that manual (thanks). It doesn’t seem to show my symbol, unless I’ve missed it.

Is there any way I can get the display to show more decimal places. Again it’s vaguely mentioned in the guide but doesn’t seem to tell you exactly how to do it.

The number of decimal places is set by the supplier config iirc. If you’re trying to submit a FiT/SEG Reading, what you’re seeing there should be fine.

That particular symbol isn’t in the manual either. I’ll see if Luke knows anything.

What I’m trying to do is this… maybe you can help?

We have 6 solar panels, and a Renault Zoe, and a home charger, and a 6A charging cable.

What we want to do is use the 6A cable and charge the car with it when the sun is shining, so most of the charge going into the car is from the solar panels.

I’ve done this but I need to check whether this is actually working… so….

I tried charging the car for an hour, and recording before and after readings, but they’re not precise enough (no decimal places) so it doesn’t really work.

Any ideas?

I think as long as the Total Active Import register isn’t moving much, you should be fine. You can also find the meter readings with decimal places on your IHD under Meter Info.

I’ll summon some extra help from @nealmurphy as one of our resident EV gurus. Hope this helps!

Any energy you generate from those solar panels will be consumed before it’s exported, and before energy is imported, @mboursnell. That’s the beauty of having an EV with solar panels. It’s like having your own battery on wheels!

Ooohhh… What EV are ya going for Luke?
