Further, the exportable 220 volts of alternating currents of said inverter controller and 20 volts of direct currents.
A kind of sun-generated electric power that the utility model provides fully by solar powered, be to the replenishing of conventional electrical network, and it is simple in structure clear, and the index debugging easily.The little fault of reliable operation; Solar module through constant-current circuit, in the time of can preventing that solar irradiation is strong, provides the protection to storage battery to charge in batteries; In circuit, designed ballast and carried protective circuit, advantages such as maintenance is easy, with low cost, easy use that it also has.
Description of drawings
The structural principle sketch map of a kind of sun-generated electric power that the utility model provides.
Embodiment
Specify the utility model below in conjunction with accompanying drawing, it is as the part of this specification, through embodiment the principle of the utility model is described, other aspects of the utility model, and characteristic and advantage thereof will become very clear through this detailed description.
As shown in Figure 1; A kind of sun-generated electric power that the utility model provides; Comprise solar module 1, charge controller 2, storage battery 3 and inverter controller 4; Wherein said charge controller 2 includes constant current charge circuit 21, and said constant current charge circuit 21 is connected between the input of output and said storage battery 3 of said solar module 1, is provided with inverter circuit 41 in the said inverter controller 4; The input of said inverter circuit 41 is connected with the output of said storage battery 3, and is provided with overvoltage crowbar 5 between the input of the output of said storage battery 3 and said inverter circuit 41.
This charge controller 2 also is included in and is connected with additives for overcharge protection circuit 22 in the charge circuit.The output of this storage battery 3 is provided with under-voltage protecting circuit 6.These inverter controller 4 exportable 220 volts of alternating currents and 20 volts of direct currents.
Solar module 1 comprises solar panel S, and storage battery 3 is energy storage battery E.Between the input of the output of solar panel S and energy storage battery E, be connected with a constant current charge circuit 21; In charge circuit, be connected with an additives for overcharge protection circuit 22; Dc output end at energy storage battery E is connected with a under-voltage protecting circuit 6; Between the input of the output of energy storage battery E and inverter controller 4, be connected with an overvoltage crowbar 5.
This constant current charge circuit 21 is made up of triode, variable resistor, conventional, electric-resistance, voltage-stabiliser tube, relay; Solar panel S charges to energy storage battery E through charging current table and triode, variable resistor; Because the effect of voltage-stabiliser tube can reach the constant current charge purpose.
Additives for overcharge protection circuit 5 is made up of voltage-stabiliser tube, resistance, triode and relay.When energy storage battery E voltage just often, voltage-stabiliser tube shutoff → triode by → relay is motionless, keeps charging; When energy storage battery E voltage is increased to when overcharging, voltage-stabiliser tube is opened → triode conducting → relay energized, and the solar cell input is cut off.When energy storage battery E can not get charging and voltage drops to when overcharging recovery point, voltage-stabiliser tube shutoffs → triode ends, relay release, and solar panel S is reclosed to charge to storage battery E.
Under-voltage protecting circuit 6 is made up of voltage-stabiliser tube, triode, resistance, capacitor, relay, buzzer and under-voltage indicator light.When energy storage battery E voltage was lower than at under-voltage, voltage-stabiliser tube shutoff → triode ended → triode conducting → relay energized, and under-voltage indicator light is bright, and buzzer rings, and this moment, voltage-stabiliser tube was connect the ability power supply.When storage battery E voltage rose to under-voltage recovery value owing to charging, voltage-stabiliser tube conducting → triode conducting → triode ended, and relay discharges, and circuit returns to normal operating conditions.
Overvoltage crowbar 5 by triode, relay, voltage-stabiliser tube, resistance,, capacitor and diode form.Voltage rises so high owing to overcharge as energy storage battery E; And overvoltage crowbar has fault or can not in time provide the protection load heavier because of the differences such as discreteness, ambient temperature, temperature or height above sea level of element characteristic the time; Can cause the inverter circuit power tube to burn; For this reason, designed by triode, voltage-stabiliser tube, be the protective circuit of core.When cell voltage＞15V, inverter circuit quits work, protective circuit.
A kind of sun-generated electric power that the utility model provides fully by solar powered, be to the replenishing of conventional electrical network, and it is simple in structure clear, and the index debugging easily.The little fault of reliable operation; Solar module through constant-current circuit, in the time of can preventing that solar irradiation is strong, provides the protection to storage battery to charge in batteries; In circuit, designed ballast and carried protective circuit, advantages such as maintenance is easy, with low cost, easy use that it also has.
The above preferred embodiment that is merely the utility model that discloses can not limit the interest field of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
