March 31, 20224 yr Our install has been operational for about a month now but im not understanding why the generation meter is reading a total of .9kwh and the invertor is saying we have generated a total of 280 kw. Should the 2 not be the same?
March 31, 20224 yr Assume you're consuming 279.1kWh within your home thus it will not be shown as "generated" as you consumed it. Edited March 31, 20224 yr by Carrerahill
March 31, 20224 yr Is it a generation meter or a grid tie export meter ..?? Would explain the difference that you have only exported 0.9kWh of the 280kWh you have generated

March 31, 20224 yr Post a picture of the meter and how it is connected. It would not be the first time the installer has connected a generation meter backwards.
March 31, 20224 yr We had the same, the generation meter was connected the wrong way round. Swopped over the input and output leads to other side of the meter and all was fine after that.
March 31, 20224 yr Author This is the meter and its wired the input from the solar and output is into meter. So if its reading low on the meter it just means we are using most of what we are producing? Thought that as power needed to 'pass through the meter' to get to the consumer unit so it could be used it would all register on the meter
March 31, 20224 yr When using that as a GENERATION meter, the "input" from the inverter goes to the left hand 2 terminals and the right 2 terminals connect to your consumer unit. We really need that photo is is not clear from your description how it is wired.

That is how it is wired up. two left terminals are marked input and they are from solar invertor and the two on the right are marked output and they go into the consumer unit.
March 31, 20224 yr It seems counter intuitive but try swapping the meter input and output and see if that reads properly.

Exactly what I had to do, when I found some instructions online, that is what it also said to do. Normal meter reads how much energy is pulled from the grid, PV meter reads how much is pushed from the inverter, so they are working in the opposite direction to each other, using the same type/ model of meter
March 31, 20224 yr The picture you posted seems to show a meter that logs import and export. Are you sure the .9kwh youre reading isnt the inverters import showing the total nightime consumption when the grid powers the inverter??

I think that might of been what was happening, I’ve swapped the input and output wires as suggested by a few people and the meter is going up much quicker so thinking it was just wired back to front.

It wasnt wired back to front, it was just the display was only showing import figure. That may have been because it only shows the current flow direction and you only looked at it when system wasnt generating and importing to power the inverter?? I think you can change what the display shows but a read of the manual would be needed!!
