120kw 3 Phase Inverter

Basic electrical specifications on solar pv inverters:

Before facing the design of a solar pv installation, we must take into account that in the market we can find, fundamentally, two types of solar inverters. We are talking about photovoltaic inverters for off-grid installations (ie with batteries) and inverters for on-grid or self consumption.

This last type of inverters, the one for self consumption and on-grid systems, is to which we make reference in this section of our web. The fundamental electrical specifications of any of the photovoltaic solar inverters on the market are:

Nominal Voltage .- It is the voltage that must be applied to the input terminals of the inverter.

Nominal Power .- It is the power that can be supplied by the inverter continuously.

Overload capacity .- This refers to the capacity of the inverter to supply a power considerably higher than the nominal power, as well as the time that can maintain this situation

Waveform .- At the output terminals of the inverter there is an alternating signal characterized mainly by its waveform and the values of the effective voltage and frequency thereof.

Efficiency (or yield) .- It is the ratio, expressed as a percentage, between the powers present at the output and at the input of the inverter.
