Areal has applied inverter technology that makes us produce digital generators.  These digital generators are extremely portable, fuel-efficient, environmental-friendly, and stable. They have excellent performance with steady electricity output. They are patented in construction. Compared with other types of Areal,s generators, Areal,s inverter generators have more outstanding advantages, such as smarter appearance, new technology and better performance. The innovative technology is that we adopt inverter technology. The inverter will purify the current which is generated from the generators. So the current can be performed a transform from AC to DC, then to AC. Consequently, the voltage output is independent of engine speed and voltage aberration will be not more than 0.5% and sine wave is smooth. Therefore, it can be used for devices se sitive to electricity such as TV, power tools.
