    50kw does not need 1000 square meters, and the system can be connected to the grid as much as possible.

    As far as the current use is concerned, off-grid power generation generally has to be used with weak current and low power consumption, both like navigation lights on the highway and some guiding lights, etc., mainly used in combination with light-emitting LEDs, and must add batteries as energy storage devices, and to do voltage stabilization and other control circuits, its power generation is self-produced and sold, and does not need to be powered by the power grid, but due to the low efficiency of solar power generation now, high-power off-grid projects can not be done.

    Grid-connected power generation refers to the direct transmission of solar power generation to the power grid for the use of users in the whole grid, mainly referring to the current photovoltaic power generation or solar thermal power generation projects. Theoretically, due to the characteristics of equal supply and demand of electric energy at all times, grid-connected this also requires energy storage, such as solar thermal through heat storage to solve this problem, but because the current photovoltaic or solar thermal is very small, MW and few are few, the impact on the power grid is very small, so it generally does not bear the load regulation, but also the state out of support for solar energy projects, so the current solar power generation grid is fully received.

    Whether the power generated is self-consumption or integrated into the public power grid, if it is self-generated and self-consumed, it can be off-grid or grid-connected, but the use of grid-connected is relatively large, the approval procedures are troublesome, and whether the local policy supports it. If it is not self-generated, it must be connected to the grid.

    Dude, you're asking too simply. Now that way is done, it depends on the specific conditions.

    Off-grid means that it does not intervene in the backbone network and is directly used by the common terminal.

    Grid connection is through the inverter, the electric energy is directly into the grid, transmitted to the distance, high-voltage conduction.

    As the name suggests:

    The off-grid system means that the electricity generated by the photovoltaic power generation system is stored in the battery, and is converted into AC power through the inverter for direct use, or directly supplied to DC power equipment without inverter, and is not connected to the power grid.

    Grid connection means that photovoltaic power generation becomes AC through the inverter, and is connected to the power grid through voltage boost or direct low-voltage side, and the power grid dispatches and uses the electric energy.

    Wind power generation, solar power generation to send electricity to the grid, must go through which link, this link to the power grid.

    Wind power generation, solar power generation will send electricity to the power grid, which link must go through, this link to the power grid to bring hello, wind power generation refers to the kinetic energy of the wind into electricity. Wind is a pollution-free energy source, the use of wind power generation is very environmentally friendly, and the amount of electricity that can be generated is very huge, so more and more countries pay more attention to wind power generation. The principle of wind power generation is to use the wind power to drive the blades of the windmill to rotate, and then increase the speed of the rotation of the limbs through the combustion of the velocity machine to promote the generator to generate electricity.

    According to current windmill technology, the speed of a breeze of about three meters per second (the degree of the breeze) can be used to generate electricity. After the power is generated, it can be used to boost the voltage of the transformer and input it to the power grid. Hope it helps.

    The maximum system of 12V of off-grid photovoltaic power generation system is A: Most of the 12V photovoltaic off-grid systems use 12V lead-acid batteries. The voltage range of the battery is: In order to fully charge the battery, the output voltage of the component must be greater than it.

    The maximum system of 12v for off-grid photovoltaic power generation system is:

    Hello dear, happy to solve the problem for you, <>

    The maximum system of 12V for off-grid photovoltaic power generation is A: Most of the 12V photovoltaic off-grid systems use 12V lead-acid batteries. The voltage range of the battery is: If you want to fully charge the battery, the output voltage of the component must be greater.

    What is the maximum size of the system that can be installed.

    Most of the 12V PV off-grid systems use 12V lead-acid batteries. The voltage range of the battery is: In order to fully charge the battery, the output voltage of the component must be greater than it.

    Take into account the temperature influence of PV modules. That is, at 25 degrees Celsius, the cell voltage drops by 2mV for every 1 degree increase in temperature. When PV modules are exposed to sunlight, the temperature of the modules can reach below 50 degrees.

    In this way, the voltage output of the PV module will drop by 2-3V at this temperature. Therefore, it is suitable to do photovoltaic blind modules with a working voltage of 17-18V.
