Hi Adam,
I will consider your advice however really not too much to go wrong in a tracker other than the electronics which is my profession so I can upgrade as necessary.
KL, Many days there is is next to zero wind while summer temp can rise to high 30's and with also high humidity so really not sure about the wind tower idea. you surely cannot generate wind from nothing.
WB, That's just it a purely DC (48V) A/C system is not power hungry. Efficiency is right up there as you cut out any conversion from the PV's DC up to AC. The compressor is a modern 48V DC unit as is the indoor fan unit.
The other advantage is one can reduce the humidity AND stay cool. The SunPower 360W panels are also breaking new ground in efficiency numbers so see this as really not power hungry and the sun comes free. If any of you have visited Cyprus then you know being much nearer the equator than good old blighty the sun here really is very powerful.
101, As you're the second in this thread to point out possible tracker issues I will think hard on this. It would be nice if I had the time and funds to do a A/B comparison re DC power generation between fixed and tracked PV systems but I agree you're probably right and investing in another couple of panels may be the best way to go.
OK on the Victrons. There is a master distributor here for this brand so I'll get some pricing and compare with DODGY TAX AVOIDERS!
Thank you all.
David
