Continuation Description

Solar cells have been known for many years and are used for all kinds of purposes, such as buffering boat batteries or similar. They are also used to operate solar motors, but not in any direct structure that makes such use possible.

Since there is no direct construction of a circuit in the sense of utilization and thus the goal of great variety is not possible, such as a decrease via an accumulator, tap and night, dT allows the operation of low-voltage devices, which is done by stabilization and can be visually controlled.

This is made possible by the construction of a number of technical components, such as measuring instruments, LEDs, discharge protection modules and voltage converters, right up to the accumulator.

The drawing shows the object of the invention in its entirety.

Function:

The solar energy is converted into voltage via the solar cells. ((1 ) , (2) , (J5) It first leads via a control device (charge control) (D1), A1, V1 , to the discharge protection module (M), where the reverse current prevents the battery from discharging. From the discharge protection module (M) the voltage leads via a voltage converter (TR), which can be controlled with 0.9 to 11 V and delivers a constant voltage of 16 V/ 7 W. This voltage can be changed by a diode. The voltage converter (TF) charges an accumulator (AC) during the day, which passes 12 V/ 9 A to the output voltage control (OU), (V2"> , (A2), (D2). Before this control is located °an on/off switch and a° green LED (Dt*), which indicates that the battery is ready for use. This is followed by the general output voltage control via an ammeter (AE) and a voltmeter (V2), also with a red LED (D2). At the voltage output terminal (A1), an on-board power socket is installed, which allows the operation of three devices, T.ax.

This system allows you to operate your own constant power source for lighting, radio, television or similar devices that are operated with low voltage in situations that cannot be connected to the public power grid, e.g. garden sheds or log cabins. " It is ensured _that the charging process during the day is sufficient to provide the

Solar cell charging device, with continuous current consumption from the accumulator . Continuation of description:

After switching on the power supply, it is ensured that the battery cannot be overcharged even if there is no voltage, because the voltage converter contains an overcharge protection device that switches off the charging process when the battery is full.

It is also possible to switch off the charging process manually, as the solar cells can be switched separately. The on/off switch in front of the charge control allows this.

The solar cells deliver a voltage of 9 V/300 nA. This ³ consists of three ( ^z ) cinsrlnrn Zsllsn.

The voltage converter delivers an output of 7 watts, but the current remains adjustable.

DiPGf storage is maintenance-free except for the accumulator. The accumulator must be checked from time to time for the water level.

The complete system is very inexpensive to purchase, because everything can be put together from vinyl parts.

This system is also suitable for installation in a caravan or mobile home .

It is also possible to have this system as a mobile power supply, for example when camping, in a practical case. The installation options are unlimited.
