Abstract

This paper presents a monitoring system design for an off-grid solar power plant with a capacity of 4 kWp. This off-grid solar power plant system was built on campus 2 of Institut Teknologi Nasional Malang. The purpose of a monitoring system is for collecting and presenting information systematically about the state of the off-grid solar power plant system. This information can be accessed anywhere and anytime by users. Hardware used includes SPM91 to read energy meters digitally, PZEM-017 as a Modbus-based measuring instrument, and communication devices to send data to a database server. The dashboard of the monitoring system was built using Haiwell SCADA software. The results obtained are in the form of a monitoring system that can display parameter data, data loggers, and graphs of the condition of the off-grid solar power plant.
