Abstract

The number of PLN power users below 2200 VA for households in Indonesia causes the use of high-powered electronic equipment (HPE) such as electric stoves, microwaves, and ovens, to be limited. In some cases, the HPE can't operate due to lack of power or being the cause of the miniature circuit breaker (MCB) down. In fact, the use of HPE can improve the quality of life of people. Power stations separated by PLN (off-grid) and high-powered are thought to be able to solve the problem due to the daily use of HPE mostly over 1-3 hours. Solar home system (SHS) can be the base power station off-grid for HPE. However, the SHS studies carried out are limited to low power below 1000 VA or high power above 3000 VA. Addressing this, the study will create high power stations between 1000 VA - 3000VA based on SHS and analyze its daily use for electrical HPE equipment such as electric stoves, microwaves, and ovens. The charging of a power station with four 100 Wp Polycrystalline solar panels can charge around 1 kWh on sunny days in Yogyakarta, Indonesia. Daily cooking activity shows the power station can support 2-3 menus daily with the usage of HPEs.

Abstract

The development of renewable energy, especially solar power, drives the need for efficient and safe energy storage systems. Lithium Iron Phosphate (LiFePO₄) battery are one of the main choices because they have stable characteristics, long service life, and are safe against high temperatures. This study aims to design a bateraiery container and a LiFePO₄ battery performance monitoring system as a power storage from solar panels. The container design considers thermal aspects, safety, and practicality of installation, while the monitoring system is built using an ESP32 microcontroller integrated with an ACS712 current sensor, a voltage sensor, and a DS18B20 temperature sensor to measure important bateraiery parameters. Tests were conducted to assess the performance of the monitoring system accuracy, bateraiery performance under charging and discharging conditions, a series-parallel plug-in connection system using an XT60 connector, and the effect of using a fan on the container at outdoor temperatures. The results show that the monitoring system has a current sensor error of 13.64%, a voltage sensor error of 1.01%, and a temperature sensor error of 4.92%. The reliability of the series-parallel plug-in connection system using XT60 connectors is considered good and works well. The cooling fan used has good usability for maintaining the battery temperature inside the container at outdoor temperatures.
