Abstract
The invention provides an independent household solar photovoltaic system which comprises a solar cell panel, a controller, a storage battery and a direct current load. The system is characterized by also comprising an MPPT device, an input switch, a direct current/alternating current inverter, a reactor, an output switch and an alternating current load. The MPPT device tracks and monitors a maximal power of the solar cell panel to ensure a maximal output power of the solar cell panel. The controller regulates and controls charging and discharging of the storage battery, and monitors and protects the system. The direct current/alternating current inverter converts current outputted by the solar cell panel into electrical energy of 220V and 50Hz for being used by the alternating current load.
Description
Technical field:
The invention belongs to field of solar thermal power generation, be specifically related to a kind of household solar photovoltaic system, particularly a kind of self household solar photovoltaic system.
Background technology:
Serious day by day along with world energy sources shortage and problem of environmental pollution, the energy and environment become the human great basic problem that is faced of 21st century, clean, the development and the application of regenerative resource more and more receive the extensive concern of countries in the world.Solar energy as the source of life on earth is human most important regenerative resource.The sun shines tellurian energy and just be equivalent to 5,000,000 tons of coals each second, and the nuclear fusion reaction of solar interior can keep tens to hundreds of 100000000 years, and for the mankind's limited life span, solar energy can be described as inexhaustible.
For above-mentioned reasons, novel solar energy photovoltaic system is able to extensive use.In more remote area, because mains supply is not very reliable, solar power generation has become the main electricity consumption source of local people's life.General independent solar device comprises solar panel, controller, storage battery, DC load; Be used in the road lighting often; But electrical equipment generally needs alternating current in the family now, and power is bigger, and therefore general independent solar device can not satisfy application requirements.
Summary of the invention:
Can not connect AC load, deficiency that bearing power is low in order to solve existing independent solar device; The present invention proposes a kind of self household solar photovoltaic system; This system can follow the trail of and control the maximum power of solar panel; Bigger electrical power storage amount is arranged, can support direct current and AC load.
In order to realize above-mentioned technical purpose; The technical scheme that the present invention adopts is: a kind of self household solar photovoltaic system; Comprise solar panel, MPPT (Maximum Power Point Tracking, maximum power point tracking) device, input switch, controller, storage battery, DC load, DC/AC inverter, reactor, output switch, AC load.Wherein the MPPT device is followed the tracks of the maximum power of solar panel and is regulated and control, and guarantees that the power output of solar panel is maximum; Its middle controller is regulated and control charging and discharging of accumulator, system is played the effect of monitoring and protection; Wherein DC/AC inverter becomes the electric energy of 220V, 50Hz to supply AC load to use the current conversion of solar panel output.
Description of drawings:
Accompanying drawing is the composition frame chart of self household solar photovoltaic according to the invention system.
1. solar panels among the figure, 2.MPPT device, 3. input switch, 4. DC load, 5. controller, 6. storage battery, 7. DC/AC inverter, 8. reactor, 9. output switch, 10. AC load.
Embodiment:
Below in conjunction with accompanying drawing the present invention is done further explanation.
Shown in accompanying drawing, self household solar photovoltaic according to the invention system comprises solar panel (1), MPPT device (2), defeated people's switch (3); DC load (4), controller (5), storage battery (6), DC/AC inverter (7); Reactor (8), output switch (9), AC load (10).Wherein MPPT device (2) carries out the tracking and the control of power to solar panel (1), guarantees that solar panel (1) moves in maximum power state all the time.A selection preferably of storage battery (6) is a lithium iron phosphate storage battery, and this kind battery volume is little, in light weight, the life-span is long, efficient is high, more smooth charging voltage platform is arranged.Wherein the selection preferably of DC/AC inverter (7) is a high-frequency inverter; Such inverter is earlier through high frequency DC/DC technology; Convert direct current into the low pressure high-frequency alternating current; After boosting through high frequency transformer then, be rectified into usually all high voltage direct currents about 300v through rectifier filter circuit again, convert the alternating current AC load use altogether of 220v, 50Hz then through the power frequency inverter circuit to.
More than be to explanation of the present invention and non-limiting, based on other execution modes of inventive concept, all within protection scope of the present invention.
