Atess 3P Hybrid Inverter For Commercial Applications HPS30/50/100/120/150

Atess 3-Phase (3P) Hybrid Inverter — HPS30/50/100/120/150

The Atess HPS30–150 series are three-phase, all-in-one hybrid inverters offering rated power from 30 kW to 150 kW, designed for small to medium commercial and industrial (C&I) energy storage systems. These units integrate PV inverters, battery charge controllers, and bypass cabinets into a compact setup, enabling seamless transitions (within 10 ms) between on-grid and off-grid operation. They support programmable modes like peak shaving, back-up, or self-consumption, and can be paralleled (up to 2 units, expandable capacity to 300 kW) for scalability. Designed for indoor installation, they are highly efficient and flexible, making them ideal for energy resilience in Tanzanian businesses.

Features & Benefits
