Atess 3P Hybrid Inverter For Small Commercial Applications- HPS15000TL/20000TL

The Atess HPS15000TL/20000TL is a 15–20 kW, three-phase, all-in-one hybrid inverter built for small commercial applications. It integrates solar PV, battery storage, grid, and load management into a compact, transformerless design. With programmable modes and seamless transition capabilities, it supports peak shaving, backup, and self-consumption strategies—ideal for businesses in Tanzania looking to improve energy resilience, reduce costs, and optimize renewable use.

Features & Benefits

• All-in-One Integration: Connects battery, load, grid, and solar PV in one device, reducing installation complexity and footprint.
• Programmable Working Modes: Flexible modes like peak shaving, backup, and self-consumption let businesses optimize energy usage, cut utility bills, and build resilience.
• Touchscreen LCD Interface: Makes on-site setup, monitoring, and maintenance intuitive and efficient.
• Seamless Transfer (<10 ms): Ensures nearly instantaneous transition during an outage, safeguarding sensitive equipment and operations.
• Dry Contact Output: Enables remote control of diesel generators (DG), allowing hybrid backup system automation.

Use Cases:

• Remote or Off-Grid Locations: Ideal for facilities like lodges, rural clinics, or small businesses in grid-scarce areas—functioning with DC coupling to combine solar and storage into a stable power source.
• Grid-Connected with Unstable Supply: In areas prone to blackouts or voltage fluctuations, the HPS can manage self-consumption and use battery or DG backup to smooth operations and reduce downtime.
• Peak Cost Management: Businesses can shift load or rely on battery during peak tariff periods to reduce energy costs.
• Backup Power Prioritization: Seamless changeovers ensure critical operations (e.g., refrigeration, lighting) continue without interruption.

Value Propositions:

• Lower Fuel & Operating Costs: By optimizing solar use and minimizing DG reliance, users can significantly decrease fossil fuel expenses.
• Enhanced Energy Independence: Resilient self-consumption and automated switching reduce dependence on unreliable grid and expensive diesel.
• Compact & Durable: Transformerless topology and IP54 protection equip it well for Tanzania’s climate—dusty, hot, and variety of installation environments.
• Ease of Use & Maintenance: Touchscreen LCD and integrated design simplify both deployment and ongoing management.

Local Market Positioning & Advantages:

• Suitable Scale for SMEs: At 15–20 kW, the HPS model directly aligns with small commercial needs—shops, schools, agro-processing units, and rural health centers.
• Cost-Effective Alternative: Compared to larger commercial or industrial systems, this unit balances performance and affordability for Tanzanian SMEs.
• Strong Technical Alignment: Features like DG remote control, durable IP protection, and programmable operation suit Tanzania’s rural energy profile perfectly.
• Scalable Implementation: While intended for small-scale, it forms a modular foundation—future expansion possible through parallel deployment.
