Solar Confusion

[wreck-it-steve]

A friend has just had 80 solar panels installed on his company roof to produce up to 20kw power that he plans to sell back to the grid...

I'm confused though because even though it does say it can produce that much it only outputs a Max of 30.3amp from the invertor and has a 32a 3 pole breaker on the main distribution board...

Am I missing something? I can't see where the 20kw figure comes from??

Yesterday it was really sunny and the invertor was reading 17.2kw output from the panels.

A 32A 3-pole breaker suggests 3-phase supply and 3-phase inverter, 32A per phase, 22kW at 230V

Of course this is, of course, all agreed with his supplier & DNO that the network can import this amount of power?

How would he get paid for it, if it were not?
