Paper work stage not installed yet.
We've had 30kw turned down in devon as it's not far from a multi-acre solar farm. Have been told by WPD that Devon and Cornwall is 'full'. Unlikely to be any private upgrades that will fix it, they reckon it will take billions in infrastructure upgrades.
we use power one with the PMU unit to control it, and elios 3 phase unit for the actual export limitation... it works, but waiting for a firmware upgrade to actually lock the setting.What make and type did you use to limit current capacity
if it is limited to 100amp.Spoke to Andy about the elios upgrade for 100 amp plus they have no intention yet to do so.
I need to limit 200 kw plus
bagsyFYI, 4-Noks are going to port across a similar system to the Elios PRO that they use in mainland Europe that allows export management for up to 200kW (maybe 250kW) systems, with security/lockout of parameters. It's an available solution but just not yet configured for the UK market. Would be handy to have an idea of potential demand though, although I know personally of multiple situations where this is required, and will probably be more frequently required as the grid gets more and more saturated.
we'd only be able to install 16 amps per phase, and even then there's a risk of inverters tripping out due to the grid voltage being pushed out of range. It's going to become much more of an issue very rapidly in the next few years as we start maxing out the existing grid capacity with very dumb controls.So if I wanted solar as every one in my street had it, you might not be able to do it as there is already enough going into the grid ?
My area has not a lot of capacity left. Solar farms are popping up all over. The cereal farmers can make more money from renting land then actually farming it.FYI, 4-Noks are going to port across a similar system to the Elios PRO that they use in mainland Europe that allows export management for up to 200kW (maybe 250kW) systems, with security/lockout of parameters.

The electromechanical solution that Worcester refers to is a valid option that is almost 100% fail safe but it's primitive in that it switches off inverter(s) completely. Most modern European manufactured inverters have a facility to throttle their output to a preset % of peak power, in several steps - something that the German/Italian/Spanish grid operators do remotely if required (or managed by 3rd parties according to grid demand etc). We have somewhat different challenges over here to facilitate this kind of control but a closed loop feedback system using something like the P1 (ABB) PMU that Gavin is using, along with an export energy monitor like the Elios can provide a decent granularity of control compared to actually switching inverters off.
The only time I was refused connection was when I came home late stinking of another bird's perfume.
now that does nark me, solar shouldn't be being installed on prime agricultural land.My area has not a lot of capacity left. Solar farms are popping up all over. The cereal farmers can make more money from renting land then actually farming it.

no problem with pasture land (particularly as much of that has been left fallow anyway with reduction in cattle herds), but prime arable land should be used for growing crops, not solar, not grazing.the clever ones are having the panels raised above ground and animals below.
they get more income from the same land then
