Off-grid system is not connected to the electricity grid and therefore requires battery storage. An off-grid solar system must be designed appropriately so that it will generate enough power throughout the year and have enough battery capacity to meet the domestic requirements, even during the rainy days  when there is less sunlight. 

The high cost of batteries and inverters means off-grid systems are much more expensive than on-grid systems and so are usually only needed in more You can add any service you want or edit the ones that are already listed. remote areas that are far from the electricity grid. However battery costs are reducing rapidly, so there is now a growing market for off-grid solar battery systems even in cities and towns. But with the introduction of Hybrid inverters the demand for old style off grid inverters diminishes...
