How does a main board know when to draw power from the grid or an Solar PV inverter?

newbieuser 4 months ago

Hi,

It might be bit silly but how does a main board/busbar etc know when to draw power from the grid or an inverter? Lets say its sunny and your PV system is generating plenty, how does the main board decide to supply the loads via the inverter and not the incoming fuse cutouts? Similarly, how does the excess current flow back to the nearest substation ?

Thanks.

hello As non tech Trying to negotiate with a solar supplier I remain sceptical of industry claims. Oh for an independent arbitrator to explain /corroborate or deny the claims

Fusion tests results say more power out than in ? Pinch salt . Ms O
