So you can operate a drill and a grinder and a light - but not all at once!

I actually have 2 sheds, one has power tools, one has motorbikes.

 

The solar is for the the bike shed which is only fans & lights,

 

That's a 600w inverter & 85ah battery but realistically I'd need a few more batteries and a fatter inverter to run anything decent.

 

I have had an extension lead running from one shed to the other just for the latter, had been thinking of getting it professionally connected but I like solar/battey setups. Something about them gives me more of a buzz then plugging an appliance into mains AC.


Hail Satan.

He needs more solar panels to power lasers against the hoards.

:) but XOR implies that at least one is on at all times!

(because there is no difference between the FALSE that disallows them all being on, and the FALSE that disallows them all being off) 

 

so i think the last part of your sentence is more fitting "not an AND" — because 'not all at once' is most closely represented by a three input NAND

 

however, i think D NAND G is probably closest to reality  :P

On the subject (sort of)...

 

Not far from where I live there's a favourite place they'd often put a mobile speed camera van.  It was practically a weekly affair on the 2 km stretch of road and of the 3 or 4 usual places along the distance this was the most common.

For whatever reason there's now a solar powered affair with a dot matrix sign, one time I drove past and saw a bunch of shiny-arses doing the wax lyrical wankfest over this thing.

If you drive past it and are under the speed limit you get a green smily face.

If you drive past in over 60 you get "SLOW DOWN" in red text.

No camera.  And for whatever reason, probably to "save money" it's a standalone thing that's self powered.

 

Now the problem here - the solar panel (all 400x400 mm or so of it) is static, pointing roughly north.  But we get shitloads of cloudy winter days not to mention a static solar panel usually being pretty poor to catch the low winter sun anyway.

 

The wanky sign, probably installed at great cost, barely works, no doubt thanks to not enough jiggawatts.

And the other problem - when it does actually work, the smily/slow down message appears when you're about 5 metres away - so if you do concentrate on reading it, you're sufficiently distracted to cause a dangerous situation regardless of speeding or not.

Man, you really overthought that joke. ;p Let me try! ;)

No, it does not - it says "only one at a time may be on". 'All off' is a FALSE from the gate, but it's irrelevant because the tools are off anyway.

supposing a gate, yes.  but your truth is still a vacuous one! :P

Actually the inverter is on 24/7 and uses about 2amps on standby.

 

Also a 240v charger for a 12v lithium deep cycle (complexly different from lead acid charger, also have not found a solar-lithium charge controller that works properly, including Victron).

just a solar assisted shed

im afraid the power bill is still 4k a quarter so the 10kw system comes up a little short of making it a solar powered shed

Holy shitballs, Dasa! WTF are you doing in there - fusion research?

I thought LEDs were the go for hydro setups these days instead of those hungry 150 watter spotlights, which should mean 10 kW just about being sufficient.

just a dairy

we should get solar hot water since we are heating 1300L of dam water each night to 90c

 

just ordered two more Philips GreenPerform 120W 16,000 LM LED Highbay $154 which will make 3 out of 5 led with two old high bays left to replace that are ether 250w or 400w not sure which

 

10kw motor drives the compressor to chill the milk in the vat

 

two 4kw motors drive two vacuum pumps when milking

 

2kw motor on a air compressor to power all the rams in the dairy

 

to provide water to the dairy\farm a 3 phase 4.4kw variable speed motor drives a pressure pump then there is two 1.5kw pressure pumps that assist when needed

another 10kw motor runs a lift pump when irrigating but its not running often

 

then there is the feed system with a disk mill, mixer and a bunch of auger motors

 

dozens of other small motors and lights

 

a video put together by the people that installed the automation system

here is a thread about the nuc\filtered pc i slapped together to run the automation software

Grow lights?

 

Don't settle for less than a 600 watter metal halide or high pressure sodium lamp paired with a digital ballast :)
