Title: 24 HR FARS Wiring
Post by: vegaman55 on February 06, 2020, 03:24:34 PM

Does anyone on here have pictures, or could get pictures of the full wiring setup of the 24hr FARS?

See Page 13 onwards in this document.

I took a different approach with my DFARs conversion.

A 12V 7ah SLA battery, 10 Watt Solar Panel (240x340mm) & charge Regulator.
Then an LM2596 Buck Regulator on the output from the battery.

The Reg has it's output adjusted down to 2.2 Volts & the fan runs pretty well at that.

Bit primitive in taking 12V down to 2.2V, but was basically knocked up with stuff I had on hand.
