Abstract
The utility model relates to a multifunctional auto-protective solar household power supply which is composed of a photovoltaic silicon array, a solar power host and a rechargeable torch matched with the host. The solar household power can provide indoor lighting and supply electricity for appliances, and over charge or over discharge of a battery can be prevented. The utility model is also provided with the rechargeable torch which is suitable for going out at night.
Description
The utility model relates to a kind of power supply, particularly a kind of solar domestic power supply.
Since present solar domestic power supply aspect anti-overcharge electricity and the anti-overdischarge all the very important person be control, so just make things convenient for inadequately.Cause overcharging or overdischarge and cause the fatigue of storage battery and reduce the life-span of storage battery easily, even storage battery is scrapped in the situation of improper use and down.
The purpose of this utility model provides a kind of multi-functional automatic protection solar domestic power supply at above-mentioned defective exactly.It is by automatic control circuit of power supply, i.e. in the convenient useful life of having protected storage battery again reliably, having increased the solar recharging torch simultaneously on main frame can use with oneself.
The purpose of this utility model is achieved in that
