Abstract:
The solar powered direct current (DC) load system is a reliable, versatile and user friendly system; it uses solar energy and rechargeable battery powering at least one type of DC load which are: a type of motor operation such as water pump and a type of at least one LED; the system comprises a battery discharge control circuit and a battery output circuit for DC load (FIG. 1), at least one rechargeable battery source (42-F1) which is protected by a preset voltage that limits the lowest discharge level, the circuits in the FIG. 1 are able to combine the circuits in FIG. 2 and FIG. 3 which enable operations of the day time and night time DC load to synchronize the day and night cycles; FIG. 4 is a combination system which incorporates circuits in the FIG. 1 and FIG. 2 to create a water pumping system combined an illumination system which can turn on and off automatically; FIG. 4a with a switch and additional LEDs in addition to the FIG. 4; FIG. 5 is a combination system that incorporates circuits in the FIG. 1 and FIG. 3 to create a water pumping system that works during the day and shuts down at night automatically; FIG. 5a with a switch in addition to the FIG. 5; FIG. 6 is a combination system which incorporates FIG. 1 and FIG. 2 circuits to create an illumination system that has at least one LED which can turn off in the morning and turn on at the evening automatically.
