Fig. 2 is master controller block diagram in the utility model.
Embodiment
In order to technological means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with specific embodiment and diagram, set forth the utility model further.
As described in Fig. 1-2, a kind of domestic solar lighting device, it comprises solar panel, storage battery, master controller, DC/AC inversion control and lighting load, also comprise DC/DC conversion to control and voltage sample, described solar panel is connected with storage battery with relay switch by forward-biased diode, due to the discontinuity of sunlight, solar panel at night or overcast and rainy generating of having no idea, farthest can utilize sky sun energy by the design of forward-biased diode and relay switch.Described lighting load is connected by switch and civil power are for subsequent use, can tackle the defect of the electricity shortage that long-time continuous rainy weather causes, and ensures that illuminator is run safe and reliable.Described master controller comprises overcharge protection circuit, over-discharge protection circuit, load over-current protection circuit, anti-reverse charging protection circuit display circuit and temperature-compensation circuit; avoid damaging system unit etc. due to improper use; can guarantee that illuminator normally, reliably works, and effectively extend the useful life of whole system.
The input of described master controller is connected with voltage sample, and data are passed to master controller by the voltage be used in monitoring system.
The output of described master controller and DC/AC inversion control convert with DC/DC and control to be connected, because photovoltaic cell output voltage is unstable, can have an impact to back-end circuit like this, therefore first circuit is converted by DC/DC conversion control, carry out inversion by DC/AC inversion control again, obtain required stable alternating current.
Described overcharge protection circuit is connected with anti-reverse charging protection circuit with storage battery, display circuit, temperature-compensation circuit, and wherein anti-reverse charging protection circuit is directly connected with solar panel.
