Tonga is making tangible progress toward its renewable energy targets with the rollout of solar-powered mini-grid systems across its outer islands, in a bold move to reduce its dependence
The main objective for the implementation is to reduce the dependency on imported fuels to lessen the impacts of climate change and to produce sustainable and clean energy in Tonga.
In this study, a two-stage grid-connected inverter is proposed for photovoltaic (PV) systems. The proposed system consist of a single-ended primary-inductor converter (SEPIC) converter
