The Atess PCS 100โ1000 series are high-capacity, bi-directional battery inverters (100 kW to 1000 kW), ideal for Tanzaniaโs growing demand for reliable, scalable energy solutions. These units support both AC and DC coupling, offer quick seamless transfer (โค 10 ms) during grid fluctuations, include redundancy, and can be combined in parallel up to 8 units to form MW-scale systems. Featuring high efficiency (up to ~98.5%), touchscreen LCD, and advanced functionalities like programmable modes and remote Diesel Generator (DG) control, these inverters are built for commercial, industrial, and off-grid applications.
Features & Benefits
- High Power Capacity: Supports massive loads across agriculture, industry, telecom, and utility sectors.
- Scalability & Redundancy: Expandable via parallel configurations; system remains operational even if one unit fails.
- Fast Transition: Near-instantaneous transfer ensures uninterrupted power, vital during outages or grid instability.
- Flexible Coupling: AC and DC coupling adapt to both solar-plus-storage and grid-enabled configurations.
- Programmable Modes: Allows for peak shaving, microgrid, backup, and other dynamic use cases.
- Remote Control & Monitoring: Touchscreen and communications interfaces enable easy operate and integrate into energy management systems.
- Environmentally Durable: Built for high temperatures, altitudes, and harsh environmental conditions.
Use Cases (Especially for Tanzania)
- Commercial & Industrial Backup: Reliable power for manufacturing, mining operations, data centers, and large facilities.
- Off-Grid Systems: Integration into solar-plus-storage microgrids in rural or remote regions.
- Grid Instability Mitigation: Systems offering frequency regulation and peak shaving to complement Tanzaniaโs national grid.
- Telecom Infrastructure: Power backup for base stations and data hubs in areas with unreliable grid.
- Utility-Scale Microgrids: Aggregate units for MW-level renewable-backed energy systems serving communities or industrial parks.
Value Propositions
- Reliability: Seamless switching and redundancy ensure stable operations even under instability.
- Efficient Energy Use: High conversion rates minimize waste and cost.
- Modular Flexibility: Start small and scale easily to match growing energy demands.
- Operational Control: Centralized monitoring streamlines maintenance and performance tuning.
- Cost Savings: Peak shaving capabilities cut energy bills and avoid diesel costs.
- Local Suitability: Designed to withstand high heat, dust, humidity, and altitudeโperfect for Tanzanian climates.
Market Positioning
- Ideal for Tanzaniaโs Hybrid Energy Landscape: Combining solar and storage is increasingly common; these inverters fit well with such setups.
- Grid Resilience Enhancer: With prolonged outages and voltage issues in parts of Tanzania, these units offer uninterrupted, quality power.
- Competitive Advantage: Few rivals offer similar scalability, power levels, and durability in the local space.
- Implementation Partners: Companies like Gadgetronix in Tanzania already distribute ATESS solutions, easing market entry.
- Regulatory Readiness: Certifications (e.g., NRS) ensure compliance with local energy regulations.
