Cogeneration Inverter

The inverter is supplied complete with all systems necessary to connect between a photovoltaic array and a commercial or domestic 240 Vac, 60/5OHZ power system circuit breaker panel. The user can sell power to his utility whenever the net solar generated energy is greater than the user's electrical load. The local utility welcomes this extra power because during midday is the time that maximum utility load occurs. The user's advantage is that nighttime power cost is partly or completely recovered by the reverse power flow at midday. This oi-directional flow eliminates the cost and bother of batteries to store excess power.

Digital Display and Selector

Unique 7-position selector switch allows settings lot: INPUT VOLTAGE, INPUT AMPS, OUTPUT VOLTAGE. OUTPUT AMP. OUTPUT KILOWATTS CABINET TEMPERATURE, AND OUTPUT KILO-WATT-HOUnS

♦ SWITCHING ELEMENTS are field effect transistors for high efficiency over a wide power range.

♦ AC OUTPUT (Utility Inter-Tie): The inverter operates in a nominal distribution system and is capable of delivering rated power at or above the specified efficiency for utility voltages of 208 Vac to 254 Vac.

♦ DC INPUT (Loaded Array Output): 48 Vdc nominal; Power tracking from 42 Vdc to 58Vdc. Operational from 35Vdc to 72Vdc. Input of 0 to 80 Vdc is not damaging.

♦ RATED POWER: 3000 watts or as limited by available power from array.

♦ REACTIVE CURRENT: Limited during steady state operation from 1/8 toad to rated toad, to between 0.95 lag and 0.95 lead at the interconnection point to the utility

♦ HARMONIC current distortion is less than 5 percent RMS. The maximum single frequency current distortion does not exceed 5 percent RMS Total voltage harmonic distortion does not exceed 2 percent RMS.

♦ RIPPLE: The peak to peak array current does not exceed 10 percent of the nominal input current at rated power. Frequency of the utility power can vary from 59 to 81 Hz or 49 to 51 Hz.

♦ EFFICIENCY: From array input to utility connection point exceeds 93 percent at full load and 92 percent from

♦ AMBIENT operating temperature 0 to 45 degrees C; non-operating -40 to 70 degrees C.
