Inverters

Inverters are used to model conversion from Direct Current (DC) to Alternating Current (AC) in an electric load centre that contains photovoltaic modules. Such a load centre has an array of photovoltaic modules that feed an inverter with DC power and the inverter produces AC power.

Tip: Electric inverters can be included in the model by selecting them on the Generator List tab of the Electrical load centre dialog when one of the d.c. Electrical buss types has been selected.

Three types of inverter can be defined:

• Simple - fixed conversion efficiency.
• Function of Power - conversion efficiency depends on power and is defined using a performance curve.
• Lookup table - conversion efficiency depends on power and is defined using a look up table.

The type of inverter can be selected using the Category option on the Inverter dialog.
