1. A stored-energy power system comprising a photovoltaic arrangement for converting solar energy into electrical energy for output, a battery arrangement, and a power management arrangement;
wherein the battery arrangement comprises a plurality of battery cells, a first power interface, a second power interface, and a switching arrangement;
wherein the plurality of battery cells is arranged into a plurality of battery groups, each battery group comprising a single battery cell or a plurality of interconnected battery cells;
wherein the first power interface is coupled to the photovoltaic arrangement for receiving solar-electrical energy;
wherein the second power interface is configured for power input from an external power source or power output to an external load;
wherein the switching arrangement is operable in a first mode or a second mode;
wherein the battery arrangement is electrically connected to the first power interface and the first power interface has a first rated voltage when the switching arrangement is in the first mode; and
wherein the battery arrangement is electrically connected to the second power interface, and the second power interface has a second rated voltage when the switching arrangement is in the second mode, the second rated voltage being higher than the first rated voltage.
