OFF-GRID SOLAR ENERGY SOLUTIONS
LESSO Solar off-grid solar energy solutions can be operated far from the area without grid electricity supply by generating,storing the energy by its own.Solar panels are used to keep the loads working and battery charging for night backup. Your of-grid solar system has to be sized properly to meet your daily power needs and make use of the stored energy pulled from the battery.
Main Advantage
It can be self-generated and self-consumed without relying on the public grid,and the excess power during the daytime can be stored for use at night to form an independent energy supply micro-grid,which can satisfy remote areas without a stable power supply, and realize a 24-hour uninterrupted supply of energy.
