“…Several monitoring systems with different technical solutions were published in 2019 [5,23,[41][42][43]. The monitoring systems for a small-scale microgrid that combined four RE installations (including PV systems and wind generators) were presented in [5]. All the devices mounted in the installation (inverters, energy meters, etc.)…”

“…Renewable energies (REs) and energy storage systems (ESSs) can reduce greenhouse gas emissions as well as dependence on fossil and nuclear energy [2,3]. Wind and photovoltaic (PV) technologies are experiencing worldwide growth due to the low cost of the energy they generate, and they are currently leading the fight against climate change [4,5]. ESSs are expected to develop considerably in the coming years since both wind and PV are intermittent sources [6], and battery storage [7] and pumped hydro energy are emerging as the most implemented solutions for adjusting the profiles of energy generation and energy demand [8].…”

The development of photovoltaic (PV) technology is now a reality. The inclusion of lithium-ion batteries in grid-connected PV systems is growing, and the sharp drop in prices for these batteries will enable their use in applications such as PV water pumping schemes (PVWPS). A technical solution for the monitoring and tracking of PV systems is shown in this work, and a novel quasi-real-time monitoring system for a PVWPS with a Li-ion battery is proposed in which open-source Internet of Things (IoT) tools are used. The purpose of the monitoring system is to provide a useful tool for the operation, management, and development of these facilities. The experimental facility used to test the monitoring system includes a 2.4 kWpk photovoltaic field, a 3.6 kVA hybrid inverter, a 3.3 kWh/3 kW lithium-ion battery, a 2.2 kVA variable speed driver, and a 1.5 kW submersible pump. To address this study, data acquisition is performed using commercial hardware solutions that communicate using a Modbus-RTU protocol over an RS485 bus and open software. A Raspberry Pi is used in the data gateway stage, including a PM2 free open-source process manager to increase the robustness and reliability of the monitoring system. Data storage is performed in a server using InfluxDB for open-source database storage and Grafana as open-source data visualization software. Data processing is complemented with a configurable data exporter program that enables users to select and copy the data stored in InfluxDB. Excel or .csv files can be created that include the desired variables with a defined time interval and with the desired data granularity. Finally, the initial results of the monitoring system are presented, and the possible uses of the acquired data and potential users of the system are identified and described.
