Program for drawing

HI

I wonder if there are any free and simple circuit-drawing programs to design PV installations. Something that you just need to put in the PV, inverter, regulator icons, wires and their sizes, fuses, etc. A bit like the one attached.

Any pointers much appreciated

Cheers
Larry

    Larry,

    When I went to design our system I was looking for something as well. A buddy of mine recommended TinyCAD. It is simple to use, has a great built in library of symbols, easy to add new ones and lots of documentation so you can learn what you don't know. This is now my go to program for circuits, floor layout and much more.

    download it here

    you can find the manual and such here

    In Niger, trying to keep a LG FMA 102NAMA fridge(This has the inverter compressor) backed up with solar using a Victron Multi-Plus Inverter/Charger Compact 12v 1600w with a 70a charger built in.I want to back it up for 4-8 hours. I am also running a few O2 cool fans and a few Thin Lite LED's of my batteries for when the grid is down so my kids can sleep.
