An off-grid solar system operates independently from the electrical grid, making it a self-sustaining power source. Off Grid Solar Power Systems are composed of solar panels array, controller and battery storage. This setup is particularly popular in remote areas where access to the electrical grid is limited or non-existent, but it also appeals to those who prioritize energy self-sufficiency and resilience. In such areas, it is best to produce your own energy via installing a solar power system. However, it is commonly used in industries and homes as well.

Off grid solar power systems are also known as standalone Solar Power Systems; these systems are totally independent of any electric utility grid.

Off grid solar power systems, or in other words off grid solar kits, are not connected to utility company. They cannot take or feed power back into the grid. They keep the energy produced by the solar system into the battery bank. The system comprises of solar photovoltaic panels which are connected to the inverter. A photovoltaic panel generates energy by its system, which can be used in supply of electrical use to any appliance that are connected to the battery storage. Off Grid Solar Power Systems are used to collect and store solar energy. These systems typically generate from 100 Watts (very small systems) to 5 kilowatts (larger systems).
