Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a marine solar charge and discharge controller. Background technique [0002] As a renewable and clean new energy source, solar energy is attracting more and more attention. With the rise of the marine industry, solar energy has become an important source of energy supply for marine equipment, especially long-term fixed-point operations and observation platforms. [0003] The photovoltaic power generation system of marine equipment is different from the system applied on land. On the one hand, marine equipment is limited by equipment shape, space, weight, etc., and there are various solar power supply systems, such as the composition of battery packs. On the other hand, limited by the harsh environment of the ocean, the application of solar power supply systems for marine equipment is also different from that on land. The importance of power supply for dif...
