The high cost of batteries and and off Grid inverter means off grid systems are much more expensive than on-grid systems and so are usually only needed in more remote areas that are far from the electricity grid.
Components of a Off grid connected Solar System:
1. PV Cells with PV Racking System.
2. AC and DC Combiner Boxes.
3. AC and DC cables.
4. Off Grid Inverter.
5. Charge Controller (mostly built-in in inverter).
6. Battery Bank With Stand
7. Safety switches and cabling.
8. Lighting Arrester (Optional).
9. Grounding /Earthing (Optional).
