Fig. 2 is the schematic diagram of the utility model controller for solar.
Embodiment
Contrast Fig. 1 the utility model is made up of solar panel, controller, storage battery and inverter, the input of solar panel connects controller, controller is connected with storage battery is two-way, and the input of inverter connects the output of controller, and inverter is output as the final output of supply unit.Solar panel is made up of monocrystalline silicon or polysilicon connection in series-parallel, the electric current that strengthens in parallel, and series connection strengthens voltage, and solar panel generates electricity according to the photovoltaic effect principle; Strengthen the power of solar panel, can be by on-off controller and the divide-shut brake coil power supply of solar panel direct output of DC current to permanent magnet mechanism circuit-breaker.Realize the reverse connection of accumulator defencive function by fuse,, protect storage battery, after corrigendum connects, change fuse and can continue to use when storage battery connects the inverse time blown fuse.
Fig. 2 is the schematic diagram that the output of solar panel connects controller; controller comprises a single-chip microcomputer; can the demonstration of realization state, overvoltage protection, overcurrent protection, cross and put protection; can realize being full of demonstration to storage battery; storage battery low-voltage alarm protection and recovery automatically, storage battery power supply and solar powered automatic switching function.Obtain the state of circuit by the indicator light LED of controller, each state can obtain voltage sample by the AD converter that single-chip microcomputer inside carries, the normal bright expression quick charge of LED is set, and LED flicker expression accumulators floating charge represents when not working that controller can not effectively charge.Overvoltage protection, overcurrent protection and crossing put voltage that protection obtains detection by single-chip microcomputer and set point relatively, as greater than overvoltage and overcurrent set point, then disconnects charging circuit, recovers behind the normal value to charge by+5V relay.Realize that by Single-chip Controlling resistance discharge recharges, reach float charging function, can prolong the life of storage battery.Realize through converter by solar energy when single-chip microcomputer and relay power charge normal, realize that by storage battery converter is voltage transitions chip LMC7805 and 5V voltage-stabiliser tube when night, cloudy day and charge fault.
When sunny, whether voltage comparator circuit can detect the input voltage of inverter greater than required value, and the 24V DC that is transformed to that establishes inverter becomes 220V DC, if greater than 24V, can directly power to the on-off controller of permanent magnet mechanism circuit-breaker, and to charge in batteries; Controller for solar can be judged by voltage ratio during faint or night when sunlight, be that solar voltage is when being lower than set point, sending signal by single-chip microcomputer makes optocoupler luminous, light coupling relay is selected automatically, if the input voltage of inverter is 24V, automatically switch when then voltage is lower than 24V, storage battery is the inverter circuit power supply, to electric, realize reliable power supply continuously by battery discharging.
