Electrifying Off-grid Regions

Systems for providing energy to areas or regions with a low level of grid reliability and which are far away from a grid are not new. However, in most cases, diesel generators are used. The latest generation of renewable system technologies is now available as an alternative to diesel units: coordinated system solutions from a single source, universally scalable and with high efficiency levels and a high degree of reliability. With our project “Electrification of grid-remote regions”, we are developing a turnkey system solution of this type.

The heart of the system consists of an MPPT charge controller, a hybrid battery (lithium-lead) and a central inverter (approx. 100 kW DC output). Flexible integration of AC and DC-side generators is possible, as is connection to a public power grid. The energy management system is the intelligent system component. Via a uniform communication standard, it connects generator and consumer to form a functional unit. A newly developed hybrid storage device (lithium-lead) guarantees the optimum use of locally available energies, and at the same time secures the independence of an entire residential area.
