Solar power plants (PLTS) with an Off-Grid system utilize batteries as a storage medium for energy produced from photovoltaic (PV) modules because the system is not connected to the PLN network. In this study, tests were carried out using VRLA (Valve Regulated Lead Acid) batteries and lithium batteries with linear and non-linear loads and using Polycrystalline and Monocrystalline modules. From the observation of 4 experimental data that we can analyze for a more optimal PLTS system circuit using Monocrystalin solar panels and using Lithium batteries, it is because from the measurement data from 4 experiments the optimal current and voltage for PV absorption and output is greater than that others with the same average irradiation and the same load used. For the load used from several types of linear and non-linear loads with the same capacity of 10 watts which is absorbed more from the battery output, LED lamps are compared to ballast lamps and incandescent lamps (AC). LED lamps because the current flowing is greater than ballast lamps and incandescent lamps. For a longer and optimal battery use Lithium batteries because the current coming out of the lithium is always stable and there is a battery management system on the cells of the lithium battery and input and output from the inverter is more optimal by using lithium batteries. In the Monocrystaline PV module with a peak voltage of 18.2V and a current of 2.54A, on a lithium battery the voltage is 13.8V and a current is 1.8A, the current for the ballast lamp is 0.26A and the incandescent lamp is 0.39 A with the same voltage of 219.2V, in an LED lamp with a voltage of 13.7V and a current of 0.7A.
