Both systems were completely designed, engineered and executed by ASET to operate all
loads in both EL-Een EL-Sokna toll station, and Suez Piscol Balance.The system was designed to maintain the maximum possible reliability by a priority method,
which shut down some of the least important loads to keep main loads operating, when battery capacity reaches to a preset value.
In addition, when battery capacity falls to a preset value, the system would automatically operate a diesel generator that will charge batteries again through an AC battery Charger.
The system can be also switched to a manual mode to operate loads through the diesel generator directly, if the solar system fails to operate due to any reasons.
The system is completely controlled via telephone modem, and all parameters of the system are recorded for analysis.
