Operation
-
The controller activates the motor at preset times.
-
Feed drops onto the rotating disc and is scattered evenly over the water surface.
-
Solar energy continuously recharges the battery.
Advantages
-
Energy autonomy (no grid connection needed).
-
Regular feeding, improving fish growth and health.
-
Reduced waste and eutrophication from uneaten feed.
-
Labor savings (less manual feeding).
-
Durable and low operating cost.
Maintenance Tips
-
Position the solar panel in full sunlight, facing south.
-
Protect from extreme weather.
-
Clean the hopper and mechanism regularly to prevent clogging.
-
Check the battery every 6–12 months.
