If you're builing a solar controller save yourself some time and take a look at this.
I've been using a cutout type solar panel regulation circuit (to control the amount of current that flows from panel to battery). There are several troubles with the current design as it requires a P-Channel MOSFET and some extra parts and doesn't work that great.
The suggestion is to switch to a short type panel controller and use an N-Channel MOSFET, which are cheaper, run cooler, more efficient etc.
Here's the original panel regulation circuit
Here's the schematic for the short type method using an N-FET.
It seems as though it will work, however I can't get the simulator to play along, which is probably an issue for another forum.
Any input on the proposed circuit?
