In November 2020, our partner WestfalenWIND travelled to Ghana to install a PV-hybrid power system at Kologo, Ghana. In March 2021, Mohammed Abass returned to the health facility to finish the set-up. In this article, he illustrates the necessity, application, and management of the system.<\/em><\/p><\/blockquote>\n\n\n\n

In Twi, one of the local languages in Ghana, dumsors<\/em> are power cuts due to low voltage or high-energy demand. They happen frequently and can last for days or weeks. Dumsors<\/em> impede the work progress of many companies and workplaces, especially health facilities, where electric power is needed the most. Sometimes, communities even must take turns to not overstrain the electricity grid. This is a huge problem for health centres, as they need cooling systems for their vaccines and other drugs that need to be stored at certain temperatures.<\/p>\n\n\n

<\/p>\n\n\n

A way to solve the problem are Photovoltaic (PV)-Hybrid power systems. One of these systems has been set up by the EnerSHelF project at the Upper East region of Ghana at the Kologo Health Centre. This aids the health facility to run 24\/7 free from any power outages that may occur.<\/p>\n\n\n\n

The PV-Hybrid power system is made up of 24 solar panels (7.2 kW peak), 12 kW of lithium batteries to withstand the charging and discharging stresses, 3 kW single-phase inverter to bring power from the single-phase grid to charge the lithium batteries when needed, as well as a 10 kW 3-phase inverter to take DC electric power from the solar\/lithium batteries and convert it into 3-phase AC current. The power system functions in such a way that there is constant electric power supply, which helps to keep the vaccines and other drugs at the right temperature and electric current to other equipment.<\/p>\n\n\n\n
