The Esdec FlatFix Fusion Ballast Container (Portrait) is a heavy-duty component designed to securely anchor solar PV arrays on flat roofs without roof penetration. Optimised for portrait-oriented module layouts, this container holds ballast blocks to provide the necessary counterweight against wind uplift forces. Made from durable, weather-resistant materials, it ensures long-term stability and protection of rooftop installations while simplifying the mounting process in non-penetrative systems.
