Solar solutions cover on-grid, off-grid and hybrid configurations, alongside solar PV panels and related accessories for both commercial and residential projects. This combination positions Modac as a single-resource provider for organisations seeking resilient power architectures and sustainable energy controls.

In the data centre arena, Modac supplies and supports a full range of infrastructure components. Customer needs are addressed through server racks and network cabinets, raised access floors, power distribution units (PDUs) and automatic transfer switches, all of which contribute to robust, adaptable IT environments. The company also offers environmental management and monitoring services—continuous, real-time collection of metrics for power, energy use, temperature and humidity—paired with remote monitoring capabilities to detect issues early and trigger rapid responses. Fire detection and suppression systems are provided to protect equipment and personnel, complemented by regular service and maintenance programs designed to sustain long-term facility integrity.

Typical engagements reflect Modac’s comprehensive approach: initial assessments and planning for data centre design, followed by strategic design work to optimise layouts, cabling, cooling and power distribution. Construction and implementation are managed to align with deadlines, budgets and quality standards, with ongoing maintenance and monitoring ensuring uptime and operational efficiency.
