ET340: How to reset the total kWh counter?

Hello,

I have an ET340 that was used as a grid meter. Then was moved to be the solar-meter now, while an EM24 replaced it on the grid side.

I would like to reset the ET340, so I know my solar yield.

I couldn't find information about this on the net. So I asked Gavazzi... they said, it is possible, but they are not allowed to tell my why, because of security reasons (if I would write what I think of them, it would violate our community policy ;-) )

So i'll try if someone here knows how to do it... maybe with the Gavazzi software?


Thanks

Daniel

Hi Daniel,

I noticed while using the Carlo Galvazzi UCS 7 software (free download from Carlo Galvazzi - search Universal Configuration Software) to trouble shoot a comms issue with my EM24, that there did seem to be the ability to reset some of the totaliser registers in the meter. I didn't actually try to do it because I didn't need them reset but it looked like you could do it.

I'd suggest giving this a try.


Cheers Tristan.

Hi Tristan.

What kind of cable is required to be able to connect to ET340 and use the UCS7 software? Can be used the same one, used to connect it to ColorGX? Thanks
