Objetivo To electrify a farm and dairy farm for autonomous operation. This center serves as a pilot agricultural and cattle farm (international training centre Spain/African countries).Satisfactory operation continues for water pumping, household electricity, street lighting.The milking machine and the milk cooler have not (yet) been installed.The load is lower than designed and hence the battery is always fully charged. As the charge regulator allows gassing of the battery, the distilled water for the battery has to be replenished monthly.Good date for the analytical monitoring for the period from January 1993 to December 1994 have been analysed.One system with charge regulator and battery, supplying through five inverters the power to the ac-loads :1.) milk cooler, (0.93 kW), Alfa Laval2.) household loads, (0.67 kW)3.) illumination, (0.71 kW)4.) Water pumping (1 kW)5.) Road lighting (0.35 kW)and directly in dc, 48 V: milking machine (2.2 kW), Alfa Laval.
