The scenario
A hybrid solar-wind charging system feeds a 12V battery that powers both an outdoor LED security light and a separate switched high-voltage insect zapper.
What is in this drawing
Read the decisions behind it.
01
Blocking diodes prevent reverse current between the solar panel and wind turbine.
02
A two-transistor astable multivibrator drives a step-up transformer to produce HV for the zapper grid.
03
Separate switches allow independent control of the security light and zapper.
Use for off-grid outdoor lighting and insect-control circuits where multiple renewable sources charge a common battery.
