Solar off-grid power generation system uses the principle of photoelectric conversion of solar energy to provide power supply for equipment in household, remote or non-electric areas.
Applications:
I. Family Use
(1) In remote areas without electricity, such as plateau, islands, pastoral areas, border guard posts and other military and civilian household electricity, such as lighting, television, etc.
(2) 3-5KW household roof grid-connected power generation system;
(3) Photovoltaic pumps: to solve the problem of drinking and irrigation in deep water wells in areas without electricity.
II. Transportation
Such as beacon lights, signal lights, sign lights, obstacle lights, highway/railway, etc.
III. Communications/Communications Areas
Solar unmanned microwave relay station, optical cable maintenance station, broadcasting/communication/paging power supply system;
IV. Oil, Marine and Meteorological Areas
Emergency power supply for oil pipelines and reservoir gates, oil drilling platforms, marine detection equipment, meteorological/hydrological observation facilities
V. Power Supply for Home Lamps
Such as courtyard lamp, street lamp, portable lamp, camping lamp, fishing lamp, energy-saving lamp, etc.
