Off-grid solar means meeting all your energy needs from the power of the sun — with no help from the electrical grid.

For most DC-coupled off-grid systems ,Off-grid systems work independently of the grid but have batteries which can store the solar power generated by the system. The system usually consists of solar panels, battery, charge controller, grid box, inverter, mounting structureand balance of systems. 

Home solar battery units last anywhere between 5 and 15 years. If you decide to install a solar battery today, it's almost certain you'll need a replacement in the future to match the 20- to 30-year lifespan of your solar power system.

(1)Solar cell components

Solar cell module is the main part of the solar power supply system, is also the most valuable component of the solar power supply system, its function is to convert the solar radiation energy into direct current energy.

(2)Solar charge and discharge controller

Solar charge and discharge controller, also known as "photovoltaic controller", its role is to adjust and control the electric energy sent by the solar cell module, to charge the battery to the maximum, and play the role of over-charge protection and over-discharge protection of the battery. Where the temperature difference is large, the photovoltaic controller should have the function of temperature compensation.

(3)Battery pack

The main task of the battery group is to store energy, so that at night or rainy to ensure the load electricity.

(4)Off-grid inverter

Off-grid inverter is the core component of off-grid power generation system, which is responsible for converting direct current to alternating current for ac load. In order to improve the overall performance of photovoltaic power generation system and ensure the long-term stable operation of power station, the performance index of inverter is very important.

The panels store enough sunlight during the day and use the excess power generated in the night. Electricity supply in rural and remote areas - Off-grid solar systems can facilitate independent, long-term and sustainable electricity generation in rural and remote areas.

Power back up in areas with frequent electricity cuts - A number of places in India face frequent power cuts due to power transmission malfunctions, which can hamper operations of companies and public institutions. Off-grid solar systems can provide an economical and viable long-term backup solution to overcome the problems occurring during frequent power cuts.

·  These self-sustainable systems can work independently and do not rely on the grid.

·  They generate enough power that can be stored and used at night or when the power grid is down.

·  These are ideal for remote areas where there is no power access from the grid.

·  Grid failures and shutdowns will not affect your power supply.
