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.

    It is worth noting that G99 conditions apply if more that one 3.6kW grid tied inverter is connected at a single premises and must get prior approval for the connection. 



    I think the 3.6kW limit is only for single phase - 3-phase would be allowed up to 11kW.




    As noted by others earlier, strictly the actual limit for G98 is 16A per phase at 230/400V. This is, in effect, 3.68kW single phase or 11.04kW three phase, but the definition in terms of current, not power, is sometimes relevant.
