Background technology
Solar energy is the treasure that the Nature gives the mankind, can a kind of regenerative resource of cleaning, if it is possible to very well
Utilization, will effectively solve the problems such as current energy shortage, air pollution, solar power generation is divided to grid-connected and two kinds of off-network, grid-connected
When need civil power stabilization could run, otherwise it is solar grid-connected generate electricity in open circuit stopped status, solar panels generate electricity energy in vain
Whitecap takes, and off-network generates electricity and then needs many batteries to carry out reserve power, when continuous many days it is overcast and rainy just occur be available for without electricity,
So it is accomplished by off-network and uses civil power, and existing electricity generation system is grid-connected and off-network is separate, it is necessary to two systems equipment is thrown
Enter, equipment investment is big, operate with very inconvenient, and solar power generation utilization rate is not high, it is impossible to maximally utilize, equipment
Can be because manual switching occur shutting down or failure not in time, many use costs of civil power electricity consumption are high.
The technical problems to be solved in the utility model is to provide that a kind of two systems merge, equipment investment is small, operates with
Solar grid-connected off-network convenient, that solar power generation utilization rate is high, equipment can normally be run, the few use cost of civil power electricity consumption is low is closed
One TRT.
Utility model content
To solve the problems such as above-mentioned prior art detection efficiency is low, fault rate is high, the utility model uses following technical side
Case：
The utility model provides a kind of solar grid-connected off-network unification TRT, including solar panels, utility grid, after
Electrical equipment, charging-discharging controller, batteries, combining inverter and off-network inverter, the solar panels and the 1 and 4 of relay
Two access terminal connection, and the utility grid is connected and be provided with break-make between the two and opens with 7 and 8 liang of access terminals of relay
K1 is closed, the input port of the charging-discharging controller is connected with the 2 and 5 of relay liang of lead-out terminals, the charging-discharging controller
Charging port connected with batteries and be provided with on-off switch K2, the output port of the charging-discharging controller between the two
Connected with off-network inverter circuit, 3 and 6 liang of lead-out terminals and the combining inverter circuit communication of the relay are described grid-connected
Inverter output end is connected after accessing utility grid with off-network inverter circuit, and the off-network inverter sets with external load electricity consumption
Standby connection.
As to improvement of the present utility model, charging indicator light is provided with the charging-discharging controller.
The beneficial effects of the utility model are：Grid-connected off-network is effectively merged, equipment investment cost, behaviour is reduced
Make using more convenient and simple, solar power generation utilization rate is also higher, it is ensured that electrical equipment has electricity available, and equipment operation is more suitable
Freely.
Brief description of the drawings
Fig. 1 is a kind of frame structure schematic diagram of embodiment of the utility model.
Specific embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with the accompanying drawings.
Refer to Fig. 1, a kind of solar grid-connected off-network unification TRT, including solar panels 1, utility grid 2, relay
Device 3, charging-discharging controller 4, batteries 5, combining inverter 6 and off-network inverter 7, the solar panels 1 and relay 3
14 liang are accessed terminal connection, and the utility grid 2 accesses terminal and connects and be provided between the two logical with 78 liang of relay 3
Disconnect and close K1, the input port of the charging-discharging controller 4 is connected with the 25 of relay liang of lead-out terminals, and the charge and discharge is automatically controlled
The charging port of device processed 4 is connected with batteries 5 and is provided with on-off switch K2 between the two, the charging-discharging controller 4
Output port and the circuit communication of off-network inverter 7,36 liang of lead-out terminals and the circuit of combining inverter 6 of the relay 3 connect
It is logical, the output end of the combining inverter 6 access after utility grid with the circuit communication of off-network inverter 7, the off-network inverter 7 with
External load electrical equipment connection, solar panels produce direct current energy to be changed through Control, work as civil power under sunlight irradiation
It is automatic that solar panels electricity preferentially can be switched to combining inverter work when power network is normal, after combining inverter work certainly
It is dynamic that electric energy is connected to the grid, when civil power is abnormal or does not have civil power, solar panels electricity can be switched to discharge and recharge automatically
Controller is worked, and batteries are charged, and charging indicator light 41 can be bright during charging, and the electric power storage of batteries is automatically controlled through charge and discharge
Device processed is exported gives off-network inverter, and external electrical equipment is connected to off-network inverter output end all the time, when utility grid restores electricity
When, automatic preferential can change solar panel electricity gives combining inverter work to relay again, automatic after combining inverter work
Electric energy is connected to the grid, it is ensured that solar panel have civil power or without civil power in the case of be all can normal power generation supply electricity to load
Use,
K1 selecting switch is devised on the control circuitry
1st, when K1 is connected, when utility grid is normal, electricity generation system is automatically selected and is incorporated into the power networks, when utility grid is abnormal,
Electricity generation system automatically selects off-grid operation.
2nd, when K1 disconnects, when utility grid is normal, force to battery charging, when there is no a civil power electricity generation system it is automatic from
Network operation.
Solar panels generating 100% is utilized, and has electricity available all the time with electric loading（Preferentially used when having civil power, when there is no civil power
Inverter power supply is supplied by off-network）.
Above-described embodiment and schema and non-limiting product form of the present utility model and style, any art
Appropriate change or modification that those of ordinary skill is done to it, all should be regarded as not departing from patent category of the present utility model.
