Swansea University, in collaboration with MOPO Sheffield and LIDAR-R Liberia, conducted extensive research in Sierra Leone and Liberia to test the effectiveness of the MOPOMax micro inverter and 1000 Wh battery system in providing reliable and sustainable electricity to off-grid communities and those effected by intermittent electricity supply. The trials focused on small businesses and agricultural cooperatives in semi-urban and rural areas, aiming to replace low-productivity manual labour and fossil fuel generators. Trials were conducted using lead-acid batteries and inverters to simulate the MOPOMax system which is currently in its first stages of deployment in both countries.

The trials involved a diverse range of businesses, including barbershops, internet cafes, and general retailers, to gauge power consumption, system efficiency, practicality and user satisfaction. The findings indicated a significant demand for the MOPOMax system, driven by its potential to enhance productivity and reduce energy costs. However, challenges such as poor electrical installations and logistical issues were identified, necessitating further refinement of the deployment strategy.

Overall, the MOPOMax system showed promise in advancing rural electrification and supporting economic development in off- and intermittent grid areas. The study highlights the importance of addressing technical and logistical barriers to maximize the impact of the micro inverter-battery technology in these regions.
