Engineering Recommendation G83 Update

Engineering Recommendation G83/2 effective from 1/3/14

Changes to Engineering Recommendation G83 will take effect in mainland UK on 1st March 2014. It is a key document for the solar PV industry, setting out the requirements for the connection of solar PV systems to the distribution network.

G83/2 contains some significant changes from the initial document. Amongst these are changes affecting inverters installed in sub-16A systems. Some inverters are already compliant with the G83/2 recommendation, some may need a firmware update and other discontinued products should be installed in mainland UK before the engineering recommendation takes effect on 1st March.

In Northern Ireland, G83/1 will still be effective.

You can see the firmware settings of each individual product at www.alternergy.co.uk/store/inverters.html
