TECHNICAL SIZING ASSUMPTIONS & DESIGN NOTES

Solar Irradiance: Sized for Addis Ababa and regional Ethiopian sun hours averaging 5.2 peak sun hours daily, factoring seasonal overcast variations.
Battery Longevity: We recommend Lithium Iron Phosphate (LiFePO4) over lead-acid due to its 6,000+ deep cycles, 85% usable DOD, and 10+ year lifespan.
Inverter Surge Capacity: Continuous loads are multiplied by a 1.25× engineering safety margin to absorb motor starting inrush currents (water pumps, fridge compressors).
Custom Engineering: Need three-phase 380V power or industrial grid-tied solar? Contact Sara Power Solution engineering directly at +251 91 080 9090.
