The Atess Three-Phase All-In-One Hybrid Inverter (≈50 kW class, often referenced as HPS 50) is a commercial & industrial workhorse that merges PV inverter, battery inverter/charger, automatic transfer, and an energy management system into one cabinet. It’s built for factories, farms, office parks, clinics, retail centres and lodges that need seamless backup, solar self-consumption, and demand-charge reduction on a 400/230 V three-phase supply.
KEY CAPABILITIES
• True hybrid operation: prioritise solar, charge/discharge batteries, and blend with grid or generator as needed
• UPS-grade continuity: fast transfer for critical loads during grid outages (installer to set essential loads)
• Zero-export & export-limit: use CTs/meter to comply with municipal rules while maximising self-consumption
• Peak-shaving & time-of-use: cut demand spikes and shift energy to cheaper tariff windows
• Generator integration: auto start/stop, soft-loading and assist to reduce diesel burn
• Multi-MPPT PV architecture: flexible string design and higher harvest across orientations*
• High-voltage LFP battery compatibility: integrates with leading HV racks via CAN/Modbus*
• Parallel/scale-up ready: combine units and expand battery capacity as your site grows*
• Remote monitoring & control: on-board HMI plus cloud/Modbus for SCADA/BMS tie-in*
WHAT’S INCLUDED (SUPPLY ONLY)
• Atess 50 kW three-phase all-in-one hybrid inverter (cabinet form factor)
