Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi,
Interesting on-line auction of panels and inverters at www.auctions.com.au in Perth. Copied this description from the web:
SMA SMC6000A Grid tied inverter 6000W
SMA Sunny Mini Central 6000A, Grid tied inverter, Includes Low Frequency Transformer, 6kW, 213V - 600V, 50/60Hz, 5 year warranty, SMC 6000A. The SMA Sunny Mini Central PV inverter is installed in locations where galvanic isolation is required. This means they can be used around the world for many different types of connections. In this way, the Sunny Mini Centrals can be used with crystalline cells as well as thin-film modules. Thanks to their graduated performance classes, they offer the highest degree of flexibility in plant design. The Sunny Mini Centrals can be used for single phase or three-phase PV arrays. END OF COPY
New price of this discontinued item is $3000 (US?) and the bids range from $300 to $420 at the moment. The bids for 75W panels are in the range of $12. Look at the catalogue. What is a three-phase PV array? Surely they mean three-phase mains?Taxation as a means of achieving prosperity is like a man standing inside a bucket trying to lift himself up.
