Each inverter has a minimum input voltage value that cannot trigger the inverter to operate if the PV voltage is lower than what is listed in the specification sheet.
What is a solar inverter start-up voltage specification?
It is important to ensure that the current output of your panels does not surpass this limit to avoid overloading the inverter. The start-up voltage specification refers to the minimum voltage required for the solar inverter to begin functioning.
What is a solar inverter power rating?
The inverter power rating signifies the total wattage of loads it can support. The power generated from the string of solar panels which is given to the inverter is called Maximum PV input power. Maximum PV input power must never be exceeded by the power output from the combined panels. Else the inverter runs inefficiently.
What parameters should be considered when stringing an inverter and PV array?
Both the maximum voltage value and operating voltage range of an inverter are two main parameters that should be taken into account when stringing the inverter and PV array. PV designers should choose the PV array maximum voltage in order not to exceed the maximum input voltage of the inverter.
How do I choose a PV inverter?
Each inverter comes with a voltage range that allows it to track the maximum power of the PV array. It is recommended to match that range when selecting the inverter and the PV array parameters. Inverter MPPT is discussed in EME 812 (11.3 DC/DC Conversion).
