Statement of Problem
Haris system is currently operating on 12 VDC. According to Aramco standards SAES-J-902 and SAES-J-505, all DC instruments should be operating at 24VDC
Objective
To make Haris system operate at 24VDC. This includes the power delivery devices such as the Solar panel, Solar regulator, battery and voltage regulator and all instrumentation. The total cost of the system should not increase significantly.
