Trio Hybrid F Series Three-Phase LV 15.0–20.0 kW Inverters

TommaTech Trio Hybrid F Series brings low-voltage battery architecture to higher-power three-phase projects. Its 40–60 V battery window supports lithium-ion and lead-acid systems, while two battery inputs and maximum charge/discharge currents of 280 A or 350 A suit installations that require substantial storage throughput.

The family supports phase-imbalanced output, generator integration, remote control and parallel expansion. Two MPPTs with two strings per tracker, 800 V maximum PV input and an IP65 enclosure make the platform suitable for professionally designed residential, commercial and agricultural storage systems.

Model Selection Guidance

Choose TRIO HYBRID LV 15.0F for 15 kW-class loads and TRIO HYBRID LV 20.0F where 20 kW nominal power, 32 kW usable PV input or 350 A battery current is required. Cable, protection and battery-bank design must account for the high DC current of this low-voltage architecture.
