4kwp system and 3 phase supply??

[BillyH]

How can i fit a 4kw system to a domestic property with a 3 phase supply? All 3 phases are being used.If i install onto 1 phase only ,then potentially the owner will only recieve a third of the electric supplied by the pv.Is it permissable to install onto 1 phase only ?
Is there a 3 phase inverter small enough for a system of this size? How much extra will it cost?

Any info would be appreciated

It would be underpowered but try matching to Sunny Tripower 8000TL. Not sure whether other maufacturers have smaller offerings.

How about using 3 smaller inverters? 3*Sunny Boy 1200/1700?

WHy are they only going for 4kWp? We've installed 50kWp domestic systems.. (Big consumers) All FIT tax free as they are not generating more that they are consuming.

They seem keen to have 4kw of solar pv and have plenty of room(and money) for 48 250w panels.Its hard to convince some folk how good an idea a large install would be.They don't have to have it on their house either
