off-grid system :: diagrams

CURRENT DIAGRAMS:

********************************

4.12.2014

  • off-grid inventory 5: (ADDED 4/12/2014) – I’m 18 months behind on this but I finally updated the inventory to include our conversion from CFL to LED lighting in the cabin. The update cost $486.10 for just 22 LED emitters. Wow how the price has changed. Non-the-less, we remain happy with the upgrade. LEDs in my observation offer much better lighting characteristics than CFLs and a wider choice of spectrum choices than incandescent.

8.26.2011

  • Cabin DC wiring 2 (ADDED 8/26/2011) – updated; now includes battery monitor
  • Cabin Power System Schematic 2 (ADDED 8/26/2011) – Completely reworked and updated! This is a huge improvement over the old schematic. And that big blank spot on the LED diagram – that is reserved for the technical drawings of the 12V LED install planned for the cabin. The wire has been run from the garage and the bulbs have been ordered. We’re going to use standard E26 screw in bulbs specifically designed for 12V DC with a wide 180° coverage with 400 lumen output at 5.6W – in other words: we can use a standard light fixture and wire it for 12V DC instead of 120V AC.

3.7.2011

Throughout the research and design phases of the project I created and updated this schematic: Cabin Power System Schematic (UPDATED 1/27/2011). Please note that the DC switches used in the LED light diagram are standard 110V AC light switches and not the toggle switches in the diagram.

  • Each item purchased in the construction of the system was also briefly catalogued in order to keep track of expenses: off-grid inventory 3 (UPDATED 7/31/2011). In this new inventory I’ve added pie graphs and itemized expenses by project.
  • I also created a DC wiring diagram (ADDED 3/7/2011) to better show how the panels, inverter, fuses, and breakers are connected.

I will continually update this post to reflect the current set up of the off-grid system.

    How do you create those fantastic schematic diagrams?

    I’ve been wanting to document my own off-grid power system. It’s been evolving for almost 40 years now and my collection of hand-drawn diagrams is more of nostalgic interest than really useful.

    I make business diagrams with “SmartDraw”, maps with ArcGIS, and house plans with Sweet Home 3D, but none of those are suitable for the level of detail that I’d need here!

    I remember a discussion in Home Power magazine many years ago about how they create the wonderful system diagrams for their magazine, but I think it was a proprietary system, not software that might be available for purchase or licensing.
