I've got an enquiry its for 4x4kw seperate systems on one building as there is 14 flats all with there own mpan numbers problem is DNO won't look at my enquiry form cause they have 12 other jobs to look at before mine, they said yours is the only one for generation but we can't pull yours out from the bottom of the pile. The same guy knows about the property as he sorted out all the seperate supplies for the flats and mpan numbers, I've mentioned the tariff being cut and I could lose this project if my client can't get the 21p tariff. He's not interested about that he said by all means call me to see how we are getting on getting through the jobs to find out when we get to yours, it's looking very tight for the end of the month though. So I'm thinking 4x3kw systems so I comply to G83 and add additional panels when the DNO say yes but installing an additional kw each would that get the 21p or fit 4x4kw and hope the DNO say it's ok (tin hat on)
Any of you guys had same problem back in February, any other suggestions are welcome

I would go for 4 x 3.68kw systems with a view to sending in 4No G83 notifications. If while you are installing the DNO give you permission for 4kw, just add the extra panels

I think you would still need permission because it's multiple installs in the same area.

Whats the main supply coming in to the block?
If it's one 3 phase then you would be limited to 3x3.68kW but wouldn't need prior.

if they are in the same location my understanding is yes, but you would be wise to check incoming voltage anywayas you may tip it over the transformer limits with that lot

Permission is granted for 12 kw to G83 but more than that is G59 hence the problem


Incoming main is 3phase
