Off-grid & Remote Power
Without a stable electricity grid, predictable and sustainable energy systems can be established
Resource-based, load-driven and energy-reserve-core buffers, which integrate photovoltaic, wind, energy storage, back-up power and communication systems to create sustainable, remote-maintenance, scalable and autonomous Microgrid in a weak or wireless environment.
Local energy autonomy
Photovoltaic, wind, storage and back-up power mix operated.
Resource uncertainty management
Energy movement is implemented at forecasting, SOC and load priorities.
Load Priority Management
Critical power supply, critical time periods and secondary load layer control.
Remotely maintained
Low-bandwidth communication, remote diagnosis and offline autonomy.
01 / System Popup
A solid and self-sustaining Microgrid leap.
Power generation resources, PCS, the energy core and the graded load share a controlled energy path.
