What is an off-grid photovoltaic power generation system? 

Solar panels can convert light energy into electricity, which can effectively deal with the difficult problems caused by power shortages and power outages. Off-grid photovoltaic power generation systems are widely used in remote mountainous areas, power-free areas, islands, communication base stations and street lamps. The photovoltaic array converts solar energy into electric energy under the condition of light, supplies power to the load through the solar charge and discharge controller, and charges the battery pack at the same time; When there is no light, the battery pack supplies power to the DC load through the solar charge and discharge controller. At the same time, the battery also supplies power directly to the independent inverter, and the current is generated through the independent inverter to supply power to the AC load.

About Off-Grid Solar Kit

A solar panel has to be connected to a charge controller to regulate current, and a battery to store the electrical power. You will need adapter kit cables to wire the solar panel(s) and charge controller, and tray cables connecting the charge controller to a deep-cycle battery.

On-grid simply means solar power equipment (array or solar panel) is connected to the electrical grid, while off-grid refers to systems that are not connected to the grid and therefore store the generated power for later use. Off-grid systems are not affected by grid blackouts.

In order to determine what size solar kit is appropriate, you must first define the total load to be expected of the solar power system. Most manufacturers will publish a specification sheet of the AC unit online and will include a nameplate sticker on the AC body. Both can be used to determine the actual power rating of the AC. BTU is a common measuring unit for energy in AC and water heater products, however we are intrested in the energy rate, or simply power. Power will be listed in units of Watts, and can be used to determine the total load resulting from running the intended AC unit. Multiply the power rating recorded in watts by the total number of hours of operation intended, to obtain the total watt-hours. Divide the total watt-hours by the peak sun hours in the location of installation, and multiply by a safety factor of 1.5-2, to obtain the total number of watts your panels should produce to power the air conditioner load. The total power load can be divided by the power output of one panel to obtain the number of panels needed.
