<p>The present invention relates to a battery-based hybrid power generator for emergency to store commercial power in a battery through a charger to be used for charging the battery using the charger to provide the commercial power when the hourly power rates exceed a predetermined threshold. The battery-based hybrid power generator for emergency comprises; an on-grid inverter to automatically cut off power transmission when detecting the storage capacity of the battery to be at or lower than a predetermined threshold; an off-grid inverter to discontinue the operation when the supply of power stored in the battery to a main load is unnecessary or the battery is being charged; and a switch (UPS) to separate power supplied from commercial power supply from power supplied from the off-grid inverter when the storage capacity of the battery to be at or lower than the predetermined threshold.</p> |
