Highly engineered modules designed to optimize DC fast charging architecture for Trinidad and Tobago
As the leading industrial economy in the Caribbean, Trinidad and Tobago is undergoing a critical transition. Famously known for its abundant natural gas and petrochemical industries, the nation is actively diversifying its energy mix and embracing electric mobility. Driven by the Ministry of Energy and Energy Industries (MEEI) and alignment with the Paris Agreement targets, T&T has implemented aggressive fiscal policies, including the waiver of customs duty, motor vehicle tax, and value-added tax (VAT) on electric vehicles.
However, scaling public EV infrastructure and industrial charging depots across Trinidad (from the Port of Spain maritime hub to the industrial complexes of Point Lisas) and Tobago (supporting eco-tourism initiatives) requires highly robust, heat-resilient charging components. Our high-efficiency power modules are engineered precisely to address the unique power grid parameters and environmental challenges of the Caribbean.
T&TEC 60Hz local grid adaptation with wide input voltage ranges to protect charging infrastructure from surges and sag.
Conformal coating with high marine-grade anti-corrosion protection specifically built for coastal high-humidity areas.
Intelligent power allocation algorithm in our rectifiers to mitigate high peak-demand surcharges from utility companies.
Deploying public chargers and fleet-specific fast charging hubs in Port of Spain or San Fernando requires an understanding of technical compatibility. Below is the operational framework of our industrial DC fast charging modules.
| Module Model Type | Power Output | Input Voltage Range | Output Voltage Range | Peak Efficiency | Cooling Mechanism |
|---|---|---|---|---|---|
| Midwest-30KW-EV | 30 kW | 260VAC - 485VAC, 3-Phase | 200VDC - 1000VDC | ≥ 96.2% | Forced Air Cooling (Dual Fan) |
| Midwest-40KW-EV | 40 kW | 260VAC - 485VAC, 3-Phase | 150VDC - 1000VDC | ≥ 96.5% | Intelligent Air Cooling |
| Midwest-50KW-EV | 50 kW | 260VAC - 485VAC, 3-Phase | 200VDC - 1000VDC | ≥ 96.8% | Liquid Cooling Compatible Option / Fan |
| Midwest-GaN-140 | 140 W | 90VAC - 264VAC, Single Phase | 5VDC - 28VDC (USB-PD 3.1) | ≥ 93.0% | Passive Conduction Cooling |
In tropical climates, ambient temperatures regularly exceed 35°C with high relative humidity. Under these conditions, standard charging modules quickly undergo thermal derating, decreasing their power output to prevent overheating.
Our modules integrate Silicon Carbide (SiC) MOSFETs and advanced dual-event thermal path designs. Our 30kW, 40kW, and 50kw charging modules maintain stable output power up to 55°C ambient temperature. This high tolerance eliminates premature power derating, guaranteeing that fleet operators in Trinidad and Tobago receive the target charge rates throughout daytime peak operation.

For island regions, relying solely on centralized grid power to fuel large-scale EV fleets creates network strain. In Trinidad & Tobago, developing decentralised charging networks powered by solar energy is key to achieving true energy independence and resilience against hurricanes.
Our charging modules are engineered to interface directly with local DC microgrids. By utilizing our Bifacial Solar Panels (535W - 555W), high-performance battery storage systems, and DC-DC converter topologies, operators can build complete "Solar + Battery Storage + DC Fast Charger" systems. Because power does not need to convert from DC to AC and back to DC, transmission losses are reduced by up to 8%.
This combined approach is highly suited for:

To deploy hardware successfully in Trinidad and Tobago, manufacturers must address local environmental factors. In coastal Caribbean areas, salt mist combined with high relative humidity creates a corrosive environment that can degrade electronic circuits.
To address these conditions, our factory applies a double-sided polyurethane conformal coating to all printed circuit boards (PCBs) in our charging modules. This coating creates an air-tight seal that protects sensitive components from moisture and salt corrosion.
Key technical features built into our modules include:
Comprehensive high-power infrastructure and components for industrial installations in Trinidad and Tobago
Key information regarding EV fast charging imports, standards compliance, and electrical grid integration
