Abstract
This paper reports the result of a field operation test of a utility load conditioner in a demonstration house equipped with photovoltaic cells. The photovoltaic cells have an area of 42 m{sup 2} and a capacity of 8.6 kW at 250V. The utility load conditioner is of single-phase, three-wire type, with a power converting capacity of 5 kW/6 kVA. The storage battery consists of two banks of sealed lead-acid batteries, each bank comprising 18 cells of 12 V - 65 Ah in series. As a result of the testing, the load conditioner was verified to cause only the excess power generated by the photovoltaic cells during daytime to flow into the storage battery banks under a reverse current flow operation mode. When the photovoltaic cell output is below power demand, the load conditioner draws as much power as is short from the storage battery banks. Under a storage battery absorbing operation mode, the conditioner makes the storage battery absorb the excess power while suppressing the reverse flow. Autonomous operation during a power failure, transfer to the storage battery absorbing operation mode, and return to the reverse current flow operation mode at power failure restoration have all operated smoothly without overcharging
