Grid Tied Inverter Installation.

Zoomup

I have been forced to forgo my international fashion modelling career and judging the Pekinise gate jumping trials in Scunthorpe, to install a grid tied inverter. I suddenly realised that I don't know anything about them beyond the theoretical. Apparently the system is a 5kW one.

 

Private solar panels are to be installed on a barn roof in the open flat countryside. Horses live in the barns/stables. The barns have a sub-main fed from a farm house TT earthed. Two residential caravans are located next to the barns. The barn owners are going to install the solar panels. I am required to just wire up the grid tied inverter.

 

Do I just bung in a B16 into the submain board, and a couple of isolators and hope for the best?

 

Do I need to consider lightning protection, S.P.D.s etc?

 

P.S. We get lots of flying insects in our homes in the sticks. Tip: If  using a hanging sticky flypaper, do not hang it below head height above your desk chair. I should know.

    The modern SMETS meters have separate registers for measuring export and import.  SMETS2 meters should be calibrated for both. SMETS1 meters were often not calibrated for export, because suppliers had no interest in measuring it.

    Older electronic meters normally stopped on export, though there was one model that added the import and export together, much to the consternation of anyone who had installed solar panels and found their bills going up instead of down.

    Not all spinning disc meters ran backwards.  The later ones had a ratchet mechanism to stop that.  I still have one, and it stops and makes strange grinding noises while I am exporting (but it hasn't broken yet).
