Isistimu yelanga engaphandle kwegridi (i-Off-grid solar system) iwuhlelo oluzimele lokuphehla ugesi welanga elingancikile kugridi yomphakathi ukuze kutholakale ugesi.Ikakhulukazi iqukethe ama-solar panel, isistimu yokugcina amandla ebhethri kanye ne-inverter.Ama-solar panel aguqula ukukhanya kwelanga kube ugesi, ogcinwa kumabhethri ukuze usetshenziswe kamuva.Iziguquli ziguqula amandla e-DC agcinwe kumabhethri abe amandla e-AC ukuze ahlangabezane nezidingo zikagesi zekhaya noma zebhilidi.
