    It is a long time since I posted on this newsgroup, as I often got flamed  
for what I felt were logical questions.  Anyway here we try again.  I have  
14 80W panels, 2,500Ah batteries, a 2000W and a 300W inverter (300W can  
supply most needs except water pumping).  Upstair lighting runs at 12V,  
all sockets and downstairs runs at 240V (AUS).  Plasmatronics charge  
controller.  My property is 7 years old and, we have no problems on being  
off grid, love it, but what about visitors...

    What is my solar problem ?  How should I design/simplify/make safe the  
battery/panel/inverter connection area?

    Ultimately, If I was on mains power, I could say to friends and house  
sitters, open the main switch box, when you arrive flick to "on", switch  
to "off" when you leave.
    This scenario, is achievable, remote inverter switch, 12V switch/relay  
but I was wondering/am intrigued as to how anyone else has done the  
1. Simplify the on/off scenario
2. Enclosed wires/inverters and against little enquiring fingers
3. Hidden the solar components/inverters/ chargers and batteries - so that  
they are unobtrusive, and cooling fan noise is supressed.

I am not after wiring diameters/qualified electrician stuff, as I can do  
that, mainly a solar switch box design and enclosure for solar system  
components, i.e. how have you done it?

    Any takers?  I can send photos of my present set-up.

    Many thanks

What voltage ?

If I'm understanding your question correctly, it's mainly how others have
enclosed/protected their installations.  My system is much smaller, but all
the "machinery" except the panels themselves is enclosed in a "power
shed".  A backup generator, inverter, and charge controller are all in the
shed, which is lockable.  The battery bank is at the back of the shed, and
not easy to open.  Except for two heavy cables, there is no communication
between it and the power shed, so no danger of battery fumes in the power
shed.  Within the power shed, the  inverter is in a Trace enclosure
about five feet up on a wall.  My family (the only ones who use the place if
not there) know how to open the Trace enclosure and touch the on-off
button on the inverter.  Aside from that button, there's nothing else to do.
