Nice work. Still waiting for the load shedding though.

THIS was a pain to get sorted. Most of the original Fuchs breakers had to be replaced to make room to get lights and plugs onto a single phase.  Fitting the new breakers on brackets intended for Fuchs breakers from the 60s is an exercise in patience & determination.

Quick question to those in the know re inverter operation.  Does it always regenerate AC thus offering a nice clean supply even in pass through or only when drawing on batteries to produce AC?

nope, only passes ac through while charging.
double conversion UPS systems always gives you a nice clean supply.
someone told me that i can make ice cubes with left over wine.
i am confused, what is left over wine?

If you instruct the inverter to always draw from solar, it will not pass through any "utility" power as my one puts it.  You have to make sure that you can replenish whatever you draw from the batteries during the day when the sun shines on the panels.  Right now for instance it is overcast, but not yet raining and the voltage from panels dropped from a maximum of 69 volts to 18 volts.  So 18 x 22 amps = 792 watts and you have to factor in inefficiencies in the charging circuit and batteries

But I expect you know all that, but there might be others who do not

Now winter in the Cape is upon us, the saving from the PV panels is not that great.  In summer (well, from October to March) I was using 8 units a day.  This has crept up to 12.  Many times now during the day the input wattage from the PV panels only just exceeds the useage.  The device goes into Bypass mode at about 6.15pm.  In summer it would be nearer 8.00pm

thin Film panels are much more efficient .

Are they much more expensive than regular panels?

Chris more or less the same price of R8.60 a watt. The problem is they only 165w panels ao you need more. Also string voltages is higher so you need more combiner boxes.

Given the new  :cr@p: that's happening, I think I need to invest in a backup solution (and perhaps save a couple of bucks month-to-month). Our region is planned for 5 March. I'm interested in going grid-tied, as I don't actually have the budget for any of this. I'd like to run only my 2 PCs and AV equipment (we use almost no household lights) of this.

I'm thinking of doing it in 2 stages:
Stage 1
1x 10x ah battery, adding exactly another one a month or 2 later
1x >=1200w inverter - what is recommended?
1x battery charger
What impact would this have on a electricity bill if the above is permanently connected to the grid?

Stage 2
Does anybody have experience in Ecco's products? I'm tinking about the 40A (or perhaps the 50A - future proofing...) http://www.valueforest.co.za/action.php?loc=South+Africa&sort=sortPriceAsc&key=ecco%20controllers
1x Solar panel, adding as needed (not sure what wattage)

Can someone anybody that has dabbled with is please assist? Any other solutions? I was looking at http://www.takealot.com/mecer-2000vu-line-interactive-ups/PLID34152441, but no long term benefits
