There are two different types of wind power generation, namely: off-grid type, which operates independently, and grid-connected type, which operates connected to the power system. Off-grid wind power generation is small-scale and can solve the problem of electricity supply in remote areas through energy storage devices such as batteries or in combination with other wind generation technologies. energy (such as complementary wind/hydroelectric power systems, wind-diesel units). combined power supply systems). Grid-connected wind power generation is a large-scale wind farm, with a capacity of approximately several megawatts to hundreds of megawatts, and composed of tens or even hundreds of wind turbines. Grid-connected wind farms can be offset and supported by the larger electricity grid and exploitmore fully iterate the available wind resources, which is the main development direction of wind power generation at home and abroad. In an increasingly open electricity market environment, the cost of wind power generation will continue to decline if the indirect benefits brought by environmental and other factors are taken into account, wind power is also very economically attractive.
Your battery settings are not complete and voltage is not given. Therefore, it is impossible to calculate the storage capacity of your battery. If calculated at 2V, the battery can only store 2V*100A*4=0.8 kilowatt hours of electricity, and your freezer consumes at least 3 kilowatt hours of electricity per year. day. Your battery is dead.
Even if your battery is sufficient, I strongly advise against your idea of consumingr electricity.
①Wind-solar hybrid refers to an ideal way to generate electricity when the wind is strong at night and light during the day in a specific area. Some places are very windy during the day, so the complementarity of settings and settings is out of the question.
② If you use wind and photovoltaic power at the same time, the supporting facilities are more complicated and the investment is large (you can also put wind power upstairs, how many wires are needed, and you are not afraid of theft), and there is no such perfect system yet.
③Wind power and photovoltaic power are not stable after all, but they still need to be supplemented with electricity. It is very reliable to rely solely on them. You still need to prepare a generator.
It is recommended ① to prepare a longer line, there must be an place with electricity on the construction site
② prepare two sets of cables sufficient batteries, one set If you are looking for a place to charge, one set is enough.
