A PHOTOVOLTAIC SOURCES POWER STATION WITH INTEGRATED BATTERYCHARGE/DISCHARGE CYCLE

摘要

An integrated power control system for transferring electric power from a photovoltaic source through a power module to a transfer switch and/or a storage battery. A monitoring system includes external current sensors that control connection of the transfer switch to the utility distribution network. Electrical energy that is generated by the photovoltaic source is directed to a load and a lithium-iron storage battery according to the level of photovoltaic power generated and according to the load demand. At times when the photovoltaic energy is greater than the load demand and the charge level of the battery is at full capacity, excess energy is directed to the electrical distribution grid. In case of grid outage, energy is drawn from the battery to maintain electric supply for designated loads.
