Power-One Solar Inverters

Power-One, a world leader in solar inverter production, offers a full range of inverters for solar installations ranging from small residential to large solar farms.  Solar inverters are an integral part to any solar power installation and convert the solar panel power output to usable voltages which can be consumed or supplied back to the utility electric grid.  Solar inverters play a key role in a solar power installation’s effectiveness and special attention should be paid to solar inverter selection. 

The power available from a solar installation is affected by the inverter’s ability to harvest the power and efficiently convert it to alternating current (AC) power.   Solar panel power generation is proportional to the amount of sunlight or photons that they receive and are affected by the intensity of the sunlight, the angle of the sunlight and any shading from clouds or shadows.  Power-One has a low input voltage that supports power production at lower solar intensity such as at dawn and dusk, extending the daily usable power production time. 

Solar inverters affect the total energy harvested by operating at the maximum power point of the solar panels power curve.  Solar panel power output is affected by the sunlight intensity, shading, temperature and total resistance.  Power-One’s Maximum Power Point Tracking (MPPT) algorithm adjusts the electrical load as seen by the solar panels to operate at the maximum power point of the solar cells.  The solar inverters continuously scan the solar panel output and adjust to operate at the maximum power point.

The third major component to maximizing the power output of a solar installation is to utilize high efficiency solar inverters.  Efficiency is the measure of power out of the inverter as a percentage of the power into the inverter.  Thus, high efficiency solar inverters use less of power in the conversion process and supply more of the power for use. 

For residential installations, the single phase Aurora™ Uno solar inverters range from 300W micro-inverters to 6kW string inverters.

For commercial installations, the larger triple phase Aurora Trio solar inverters, the three phase Aurora Trio solar inverters ranging from 10kW to 27.6kW, and the central inverters can be provide optimized solutions.

For utility solar farms, Power-One’s central inverters provide power for up to 1.3MW in a prefabricated weatherproof cabin to enable simple and speedy installation.
