Hi Josh,

yes that is one of my rigs, with one of my PME's (not the one you had; which I am still yet to turn on).

Further development in the last week or so. We are working on the passive cooling of the containers. A whirly bird has been installed with ground vents and the containers have been spray painted in surf mist. So far the improvement has been significant on the internal temperatures. Next step is to create an insulative box within the container which holds the batteries and power systems. That should then hold day temperatures to 26 degrees C all year round.

Hi Paul, that sounds pretty good. Is the insulated box within the container going to be touching the inside walls, or will it be a box (much smaller) with the container? Just thinking about any heat that the batteries give off, needing to escape and a too small a insulated box for the batteries, holding that heat in.
Looks great so far, its going to be a lovely facility.

Yes the insulation will be touching the side walls. Problem being that batteries rack is bolted to the floor and the batteries are very heavy to move at 70kgs each. It is a bit of an oversight but there are solutions to the problem.

Regarding the heat the batteries give off I will construct the box to be about half the size of the container, allowing room for expansion with another power station later when we build another shed.

It occurred to me that you could significantly increase the insulating value of the container if you spaced the insulation off the container wall by 50 to 100mm.

Final testing tonight of one of the dome imaging systems. That being the AG12 and QSI683 on PME mount. Seeing looks pretty reasonable overall. Guiding looks good too. Now just to collect lots of data. It's been a rather dry spell.

Hi Trevor, some of this is already in play. We have CCTV and alarm systems in place. We have been reliably informed that we cannot place a minefield on the site, so I guess that is not going to happen . Not sure about the robotic dog either. I am pretty sure I don't have the capital for that outlay . A fence is on the agenda when we are approaching being online with customers. Although locals in the area have advised being inconspicuous. Large fences and signs apparently attract unwanted attention. For now it is pretty well secure with high security locks to all doors and the cameras informing of any intrusions to the site. None as yet fortunately.
