our green energy solutions

Grid-connected Photovoltaic Power System Solution

Quang Anh build a green energy system which a grid-connected PV system consists of solar panels, inverters, a power conditioning unit and grid connection equipment and substation.

It has effective utilization of power that is generated from solar energy as there are no energy storage losses.

When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load to the utility grid.

But, in stand-alone systems batteries are used to store energy or else energy has to be directly connected to load.

Optimaze Power Factor & Harmonic Filtering

Quang Anh CE offer a range of products and services to ensure assess, harmonic filtering and improve power factor.
Our power factor correction and harmonic filtering equipment includes checking that the system is operating at optimum performance levels. We check the following:
Electricity load reduction
Voltage levels
Harmonic content
Detailed equipment condition
Full functional operation
