The Tritium type 3 solar engine motor control

The Tritium circuit was the first (to my knowledge) type 3 SE. As such, it is quite experimental, and should be regarded as a prototype rather than the ‘state of the art’! Nevertheless, it does function reasonably well, and in some circumstances outperforms other solar engines such as the Freds that I have lying around.

Solar Panel controller by 12F675

The purpose of this project is to realize a Solar panel controller. Initially developed for a sailing boat, the target to reach was to control the level of charge and discharge and to protect a 12 volts lead battery connected to a 32 watts solar panel.

The project is based on a 12F675 and uses HEXFETs to switch the load and the solar panel. The programs were developed with PROTON+ and around 10 of those small devices are today doing their job without any problems. The use of a PIC processor gives a large access to the way the load is used (with or without over voltage protection) or how the controller reacts when the full charge level is reached. This gives a lot of improvement possibilities.

This project has absolutely not the intention to show the best and most effective way to program. After all, I am a hobbyist too. It is a example of how to solve quickly a problem with a small and robust realization.

Solar Regulator by 2N3906

The SIMD1 was enhanced in the Solar Regulator version which supplies a constant 2V after triggering and permits driving LEDs without using current limiting resistors with constant brightness. Note that you can use this Low Drop Out (LDO) linear regulator for various applications but like all linear regulators it is “lossy”. This is not a problem for controlling LEDs since they would otherwise use “lossy” resistors but for motors it is a different story.
