Peralihan penggunaan minyak dan gas alam ke energi terbarukan khususnya energi matahari sangat diperlukan saat ini. Pada sistem Pembangkit Listrik Tenaga Surya (PLTS), penyimpanan energi menjadi kunci. Penelitian ini menggunakan sistem hybrid PLTS yang mana fungsi SCC mengatur listrik dari PV, kontrol arus baterai mengelola aliran masuk dan keluar dari baterai, sedangkan genset menyediakan listrik saat PV dan baterai tidak mencukupi untuk memenuhi kebutuhan beban. Hasil penelitian menunjukkan Pengendalian arus dengan penyimpanan baterai cmenggunakan kontrol Proportional Integral dari pengaruh suhu dan radiasi pada saat kondisi charging, kondisi discharging, kondisi PLTS dan baterai menyuplai bersama dan kondisi generator AC menyuplai telah berhasil dilakukan. Pada pengujian kondisi charging, diperoleh tegangan sebesar 30 V, arus PV sebesar 15 A, total daya 430 Watt, tegangan beban 100 V, arus beban 8 A, tegangan pada baterai 48 V dan arus baterai dengan nilai -17 A. Pada pengujian kondisi discharging, diperoleh tegangan beban sebesar 0 Watt, arus beban sebesar 8 A, tegangan PV 48 V, tegangan pada baterai 25,6 V dan arus sebesar +18 A. Pada pengujian kondisi PLTS dan baterai menyuplai bersama, didapatkan hasil tegangan PV sebesar 29 V, arus sebesar 7,5 A, total daya 212 Watt, tegangan beban 48 V, arus beban 8 A, tegangan pada baterai 25,7 V dan arus +10 A. Pada pengujian kondisi Generator AC menyuplai, diperoleh arus beban sebesar 17 A, tegangan pada beban sebesar 100 V dan arus pada baterai sebesar -15 A. Hasil pengujian pada semua variasi radiasi dan suhu menunjukan bahwa kontrol Proportional-Integral dapat bekerja dengan baik untuk digunakan sebagai pengendali arah aliran daya pada baterai.

Switching the use of oil and natural gas to renewable energy, especially solar energy, is very necessary at this time. In Solar Power Generation (PLTS) systems, energy storage is key. This research uses a hybrid PLTS system where the SCC function regulates electricity from the PV, battery current control manages the flow in and out of the battery, while the generator provides electricity when the PV and battery are insufficient to meet load needs. The research results show that current control with battery storage using Proportional Integral control of the influence of temperature and radiation during charging conditions, discharging conditions, PLTS and battery supply conditions together and AC generator supply conditions has been successfully carried out. In the charging condition test, the voltage obtained was 30 V, the PV current was 15 A, the total power was 430 Watt, the load voltage was 100 V, the load current was 8 A, the voltage on the battery was 48 V and the battery current was -17 A. In the discharging condition test, obtained a load voltage of 0 Watt, a load current of 8 A, a PV voltage of 48 V, a voltage on the battery of 25.6 V and a current of +18 A. In testing the conditions of the PLTS and the battery supply together, the results obtained were a PV voltage of 29 V, current of 7.5 A, total power of 212 Watts, load voltage of 48 V, load current of 8 A, battery voltage of 25.7 V and current of +10 A. In testing the condition of the AC Generator supply, a load current of 17 A, voltage was obtained. at a load of 100 V and a current in the battery of -15 A. Test results for all variations in radiation and temperature show that the Proportional-Integral control can work well to be used as a controller for the direction of power flow in the battery.
