me too...Hope it was his generation meter
not in my world they don't.
A rock that weighs the same as a feather would be known as a pebble, not a rock, so a feather will always fall slower than a rock even in a vacuum.
Now, if we were discussing pebbles and feathers.......
Well I called the Dno at 4pm had a chat to a lovely lady about the high voltage with regard the pv setup and she amedietly said it sounds like you need it tapping... Anyway engineer turned up at 6:30 did some tests dispite his test was within range he took a look at my PVO logs and agreeded it needs to be looked at, so they are arranging a monitor to be put on my supply, watch this space

oh dear danesol, you completely missed the point!:banghead:
yes, they do in a vacuum, i.e. in the lab, but not in real life, thats why I said because of the presence of other factors. The same as in real life the voltage of your panels will not increase after may.
I know we have just had a long bank holiday but wakey wakey!!

One question to the OP where are you getting your voltage reading from?
Is it from the inverter or are you checking the incoming supply when the PV is not producing?

so, if she weighs the same as a duck, she must be a witch!

thats why I suggested he needs someone to look at the installation. It needs a proper evaluation on the ground.

long 2.5 maybe?
Im getting my readings from the inverter but the engineer tested the incoming supply with the house disconnected and was getting 246v when he put the supply back on and the inverter started generating again it was measuring grid at 246.5v

IMO, this needs to be repeated at say peak generation time to see what the actual grid voltage is then... before reconnection
At least now you know its a fairly accurate reading, what you need to know now is why is goes up so high at certain times/generation periods - is it your kit and/or surrounding environment ?

I think its environment sending it up to 250v and generation taking it to 253v im seeing a lot of voltage spikes with low generation

thats interesting, 246V is fine, but voltage spikes of 250 is going some. The previous advice of asking others in the area if they get problems with bulbs blowing a lot might be a good idea. I wouldn't make too much fuss to the DNO about your PV system as they may blame that and tell you to switch it off! are there a lot of other PV systems in the area (sorry if this has already been asked)
Actually i noticed i local housing association has covered a full row of houses with panels i would estimate 25-30 kWh
M
moggy1968
ok, if thats on the same transformer that could push the voltage up
