Power Conditioner for Photovoltaic System

Power conditioners for photovoltaic systems (central inverters) convert DC electricity generated by solar panels (photovoltaic cells) into AC electricity with high efficiency. They are also equipped with various protection and control functions required for connection (interconnection) with the AC commercial power grid.

Features

Smart Power Conditioner

1. High functionality and high efficiency

The conversion efficiency of the power conditioners (outdoor specifications) is among the top in the industry. The power conditioner incorporates the DC current collection function and control power source.

2. Compact design

The height of the power conditioner’s main unit is 2 m or less. Because the shadow cast by the main unit is small, photovoltaic cells can be installed close to the main unit, achieving effective utilization of space.

3. Energy conservation achieved by eliminating the need for an air conditioner

The hybrid cooling method (using both a heat exchanger and forced air cooling) is used. It is highly energy-efficient because it does not require an air conditioner whose power consumption is high.

4. Long service life design

It is recommended to replace parts every 10 years.
