- 3-level inverter topology for increased efficiency and high power density
- Adjustable battery number up to 40pcs for high efficiency
- Parallel operation up to 3 units
- Built-in backfeed protection
The PowerWalker VFI CPG 3/3 series is a professional commercial solution built in double conversion technology with power factor 0.9. Equipped with three-level inverter topology, it results in high efficiency reaching 95% in Line Mode and even 98% in ECO Mode. The series ensures low harmonic distortions and precise voltage regulation (1%). All phases have Active Power Factor Correction.
Thanks to its modern design, the VFI CPG series reaches a very high power density (kVA output in relation to the size/volume of the unit). All models of this series offer generator support, communication ports for SNMP, USB and RS-232 and allow parallel operation up to three units.
For this model battery numbers can be adjusted (between 32 and 40pcs), allowing more flexibility and compatibility with existing battery banks. The three stage extendable charging design also enhances battery performance over its life time. For safety reasons this series has been equipped with backfeed protection (reverse feed) in order to avoid power transfer to the input terminal in case of mains failure.
