DIY install advice before I start wasting my Cash :-)

Not necessarily. Many of these inverters can pass more current than they can generate themselves, for example the 3KVA Multiplus I mentioned can deliver a whole 50 amps on the output as long as the grid is available on the input. As I recall, the Infini also has this feature.

Wow! Ok... This is interesting stuff, so I only need to use the relay to tell me to run to the DB and switch off the Heatpumps etc.

Anybody had any experience with Artsolar panels. Prices seem very good

No, but I cant see any reason why their panels would be any better/worse than any of the multitude of Chinese multi-crystalline panels available. I previously used Setsolar panels which are also RSA made and was very happy with the product. Setsolar/Artsolar sound very similar, I wonder if it is not some kind of breakaway?

They are well priced, I would be happy to use them.

I use the infinisolar 3KW plus which is capable of 6KW throughput in hybrid mode when the grid is available. My entire house including the geyser runs through the inverter as I wanted the excess solar power to heat the geyser at mid day as the geyser runs on a timer. I did replace the 3KW element with a 2KW element to keep the load within the inverters capabilities.

I had a relay installed that completes the circuit for the dishwasher, washing machine and geyser so that should the power trip when these are in use, the load on the inverter is reduced to my base load of around 500W. This prevents the inverter from tripping on overload if the power goes out.

Some people (see SolarNoob above) use a contactor that is powered by the grid to switch the high load items off when the grid goes out. So these items are connected to the inverter output (so they benefit from the PV), but don't draw it down when there is an outage.
