However for different plants requires a hybrid system. This is a solution for remote areas that still use Genset / PLTD as a source of electrical energy to serve consumers / load This study aims to examine the charging current of a solar energy hybrid generator with a Genset / Diesel and the time used to fill the accumulator in conditions without load and load conditions. The results showed that the solar energy hybrid generator and Genset / Diesel prototypes were able to produce electrical power at 08.00 - 17.00 in the average sunny weather of 290.7 Wp without loading and at the time of load of 236.4 Wp. At night, the energy stored in the battery is converted into electrical energy to supply the load. Thus it can save electrical energy. Key words: System Hybrid; Solar Energy; Genset/Diesel Generators.

INTRODUCTION Today, the source of electrical energy that is of concern is solar energy and vegetable energy because it is easy to obtain and environmentally friendly. This situation helps the government in saving electric energy especially in offices, hospitals, housing and so on, because the electricity produced does not use fuel oil. Indonesia's large enough area separated by land and sea is one of the factors of inequality in PLN electricity services so that the archipelago uses electricity generation separate from the interconnection system. Thus, PLN must build a PLTD or GENSET in serving customers or people who live in rural areas, especially in the islands. This situation is very influential on the development of current technology and rural economic growth. Seeing this condition, the
