The Atess PCS 100–1000 series are high-capacity, bi-directional battery inverters (100 kW to 1000 kW), ideal for Tanzania’s growing demand for reliable, scalable energy solutions. These units support both AC and DC coupling, offer quick seamless transfer (≤ 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 Tanzania’s 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 altitude—perfect for Tanzanian climates.
Market Positioning
- Ideal for Tanzania’s 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.
