3.2 MPPT J-energize

The 3000 watt Solar Converter is designed to convert energy from solar panels into regulated -48VDC for telecom applications. The converter operates in MPPT (Maximum Power Point Tracking) mode, enabling maximum power extraction from the solar panels throughout the day.
The J-ENERGIZE converter is used as an integral part of hybrid power systems for telecom applications.
The Solar Converter provides energy from solar panels to telecom sites in the access and transmission network. Together with other energy sources (such as battery, diesel generator and wind turbine), the J-ENERGIZE converter contributes to a reliable supply of energy. The high conversion efficiency and ability to accurately track the MPP (Maximum Power Point) will contribute to optimal utilization of the installed solar panel array.
For main technical parameters of J-ENERGIZE converter, see Table 3-2.
