HYbrid Energy HES Mini 20kW 48Vdc Generator
The HES Mini is a hybrid generator designed for providing primary power to off-grid telecom sites that have 48Vdc equipment. This unit can save from 30-50% on fuel and O&M costs on a typical telecom site, and these savings can be increased by adding solar panels (plug and play). This unit includes
- DC generator powered by a Perkins 404D-22 engine coupled to a Permanent Magnet DC alternator
- Battery rack capable of holding up to 52kWh of LG Chem Li-ion batteries allowing the system to be optimally sized based on the site load.
- 1000L Base fuel tank tank to long autonomy
- Advanced hybrid controller with remote monitoring and control
- Optional solar panels with frame for mounting above the hybrid generator.
