Trio Hybrid S Series Three-Phase HV 5.0–25.0 kW Inverters

TommaTech Trio Hybrid S Series provides a broad three-phase high-voltage platform for residential, commercial and light-industrial energy storage. Eight exact models cover 5 kW to 25 kW, allowing designers to maintain one consistent family as project load and PV capacity increase.

The series supports three-phase unbalanced output, AC coupling, generator integration and parallel expansion up to ten units. Its 160–700 V lithium-ion battery window, two MPPT architecture and IP65 enclosure suit both new-build storage systems and professionally engineered retrofit or backup applications.

Key Features

• Eight exact models from 5 kW to 25 kW
• Three-phase unbalanced output

• IP65 enclosure and up to 97.6% maximum efficiency

Recommended Applications

• Three-phase homes and premium villas
• Apartment common services and mixed-use buildings
• Retail, hospitality and small commercial sites
• Agricultural facilities and workshops
• Light-industrial self-consumption and backup systems

Model Selection Guidance

Use 5–12 kW models for lower three-phase loads and 15–25 kW models where sustained load, PV capacity or backup demand is higher. Confirm the exact MPPT/string arrangement and battery current at the selected power. The official sheet prints an unusual 8/4.8 A maximum AC input/output value for the 5 kW model; it is retained verbatim and should be confirmed during final project engineering.

Editorial Source Notes

• The battery range is written as 160/700 in the official sheet and is presented as a 160–700 V range here.
• The 5 kW maximum AC input/output current is reproduced exactly as 8/4.8 A from the current official sheet; obtain written technical confirmation before using this value in final protection or cable calculations.
