Read MoreThe Delta Eltek Flatpack2 48/3200 HE Solar Converter is a high-efficiency MPPT-based DC/DC module designed to integrate solar PV input into Flatpack2-based telecom and industrial DC power systems.
An advanced MPPT algorithm ensures near 100% utilisation of available solar energy, while galvanic isolation and input ground fault detection enhance safety and system integrity. With a wide input range (85–430Vdc) and peak efficiency exceeding 97%, it delivers up to 3200W of regulated 48Vdc output per module.
Fully integrated with the Eltek control platform, the converter supports string current optimisation, passive current sharing, and fault monitoring. Designed for hybrid and off-grid systems, it enables reliable solar integration across 1U, 2U, and 3U Flatpack2 power shelves.
