British Council, Eritrea, Back-Up System

Project description

The system powers essential loads of the British Council in Asmara, Eritrea during power cuts for 10 hours. The batteries are charged from the grid.  Additionally a solar generator is included in the system to charge the batteries in case of longer power cuts. The system guarantees s a reliable power supply without interruption during the switch from grid power to battery power.


Why was PV selected?

The PV generator supports the battery back-up system in case of longer power cuts.


Special challenges

The power supply in Eritrea even in the capital Asmara is not reliable. Power cuts of some minutes up to several hours are common. A battery back-up system is a suitable solution to supply reliable power to essential loads.
