Abstract

The invention relates to a power system for supplying large current to solar photo-voltaic cell, wherein it comprises the energy part with solar battery and accumulator, the boost part with DC / DC boost circuit, reverse output part, and the control part with microprocessor. The invention is characterized in that: the energy part has super capacitor; the boost part has three parallel DC / DC boost circuits via independent switch connected to solar battery, accumulator or super capacitor. The invention can supply instant large start current safely to device.

Description

technical field [0001] The invention relates to a power supply system, in particular to a solar battery system which combines solar batteries and battery packs and can provide loads with alternating large starting current through inverter devices. Background technique: [0002] Solar energy is a kind of renewable green energy. In the current situation where fossil fuels such as oil, coal, and natural gas are increasingly exhausted due to massive exploitation, the development and utilization of solar energy has been widely valued by countries all over the world. Compared with renewable energy sources such as wind, water, and tidal forces, solar energy has the advantage of not being limited by the site, especially it can make full use of the roof and exterior walls of buildings, and does not need to occupy a large amount of land for solar energy collection. , and it is commendable that the use of roofs and exterior walls to collect solar energy will not only have no negative i...
