Abstract

Solar power plants require other supporting equipment besides solar panels, including SCC (Solar ChargerController) for solar panel charger media to batteries. While the battery itself as a store of electrical energy generatedby solar panels. Therefore, other supporting equipment is very important in the application of solar power generationsystems.In the charger system or battery charging on solar panels, an SCC solar charger controller is needed as the chargermedia. In the solar charger controller there are two types between MPPT (Maximum Power Point Tracker) and PWM(Pulse Width Modulation). This study aims to analyze the performance comparison between SCC which is good forsolar panels in battery charging. Apart from the comparison tool, the simulation tool used in this study is which oneis superior between MPPT and PWM. The way of comparison is to compare the current and voltage results obtainedfrom the SCC input and output between MPPT and PWM to find out which one is superior.The results of the comparison with simulation produce current input from MPPT between 10, 15, 20, 25 A while PWMinput current is between 10, 15, 20, 15A. The results of the MPPT current output are between 12, 18, 21, 25A, whilethe PWM output current is between 8, 18, 21, 25A. For the MPPT input voltage results are between 29, 25, 36, 41V,while the PWM is between 26, 29, 36, 41V, while the output MPPT voltage is between 14, 14, 15, 15V, while the PWMis in the range of 14, 14, 15, 15V.

Abstract

Batteries have an important role in the development of energy needs. Good battery performance will support the devices it supports. The energy that can be stored in a battery is limited, so the battery will experience a cycle of charging and discharging. Improper charge and discharge processes can cause battery performance to decrease. Therefore, it is necessary to monitor battery performance in order to determine maximum battery performance. One of the aspects needed to monitor the state of charge and Depth of Discharge is to monitor the voltage, current and temperature on the types of lithium ion and lithium polymer batteries as energy storage for solar panels by using Arduino Atmega as a controller to determine the percentage of lithium ion and lithium polymer batteries and displayed on the LCD as HMI. From the results of comparing the performance of lithium ion and lithium polymer batteries, the results of SoC and DoD are measured and displayed on the LCD accurately, it can be seen which one is faster in charging time and lasts longer in use so that performance can be known of the two types of batteries.

Abstract

The constraints of gas distribution pipe leak monitoring robots in outdoor environments are the limited battery capacity and the method used as a monitoring system to assist the work of gas pipe leak inspection officers, which takes a long time. Therefore, the robot requires independent battery charging and real-time monitoring systems. This study resulted in a solar-powered gas distribution pipe leak monitoring robot that can provide real-time information on the robot's battery capacity and gas odor concentration data along the inspected gas distribution pipe. This robot can directly channel electrical power to the robot's battery using solar energy. This Mobile Robot uses a Photovoltaic (PV) module, Light Detection and Ranging (LiDAR), a Compass, a gas sensor, a voltage sensor, a current sensor, an ATMEGA 2560 Microcontroller, and Node MCU V3 ESP8266. The Internet of Things (IoT) application uses the Blynk application to monitor battery capacity and the concentration value of gas odor detected by the robot. The test results show that by using the PV + battery module, this mobile robot can work for more than 60 minutes compared to using only the battery for around 55 minutes. This work was successfully implemented based on IoT performance using the Blynk Application to monitor battery capacity conditions of voltage and current data and gas concentration data. It is also shown that the average delay time for sending data from voltage, current, and gas sensors to the Blynk application was around 0.226 seconds.
