DC/AC Inverters
The standard DC/AC inverters start at 125VA and rise to redundant modular systems capable of a 48kVA output. All our inverters give a true sinewave output and have proven themselves to be
Some or all of the specifications usually appear on the inverter data sheet. Maximum AC output power This is the maximum power the inverter can supply to a load on a steady basis at a specified output voltage. The value is expressed in watts or kilowatts. Peak output power
Output specifications cover nominal AC output power, maximum AC output power, AC output voltage range, grid connection requirements, and power factor range. The input specifications of a solar inverter relate to the DC power generated by the solar panels and their compatibility with the inverter.
Because POUT (efficiency) (PIN) PIN = POUT/efficiency Using peak efficiency, the input power to the inverter must be PIN=POUT/Peak Efficiency=3,300 W/0.953=3,463 W Using the CEC efficiency, the input power to the inverter must be PIN=POUT/CEC Efficiency=3,300 W/0.945=3,492 W Inverters can be classed according to their power output.
Large commercial inverters are in the 60 kW to 100 kW range. Inverters can be combined to provide up to or above 1 MW (1,000 kW) of three-phase power. Review Questions What determines the required input power to an inverter so that it achieves a specified output power?
