The two-phase battery installation at the refinery site.
Overview
Unilam Pressings is a leading steel-components manufacturer with a large factory in southern Johannesburg. Repeated vandalism of grid infrastructure forced the operation to rely on diesel generators at a cost of hundreds of thousands of US dollars per year. The solar-plus-storage system was designed to lower energy cost when the grid is available and reduce generator use during frequent outages.
