With the continuous popularization of solar photovoltaic, solar photovoltaic power generation is now used in many fields, which is convenient, energy-saving and efficient. However, no matter which field it is in, a solar controller is definitely needed to protect the battery from charging and discharging, as well as the automatic adjustment function. The following describes the specific scope of use.

1. User solar power
(1) Small-scale power supplies ranging from 10-100W are used in remote areas without electricity, such as plateaus, islands, pastoral areas, border posts, etc. for military and civilian life, such as lighting, TVs, tape recorders, etc.;
(2) 3-5KW home rooftop solar grid-connected power generation system;
(3) Photovoltaic water pump: solve the drinking and irrigation of deep wells in areas without electricity.
 2. Transportation
Such as beacon lights, traffic/railway signal lights, traffic warning/signal lights, Yuxiang street lights, high-altitude obstruction lights, highway/railway wireless phone booths, unattended road shift power supply, etc.
3. Communication/communication field
Solar unattended microwave relay station, optical cable maintenance station, broadcasting/communication/paging power supply system; rural carrier telephone photovoltaic system, small communication machine, GPS power supply for soldiers, etc.
 4. Petroleum, marine and meteorological fields
Oil pipeline and reservoir gate cathodic protection solar power system, life and emergency power supply of oil drilling platform, marine detection equipment, meteorological/hydrological observation equipment, etc.
Five, home lighting power supply
Such as garden lamps, street lamps, portable lamps, camping lamps, mountaineering lamps, fishing lamps, black light lamps, tapping lamps, energy-saving lamps, etc.
