TommaTech Hightech Power 3.0 Series HV LFP Battery System
The TommaTech Hightech Power 3.0 Series is a modular high-voltage lithium iron phosphate energy storage system based on a 30 Ah LFP battery module and a dedicated Storage Manager.
Unlike a conventional standalone battery, the architecture uses the Storage Manager as part of the complete battery system. One to four TT 3.0 kWh battery modules are then combined with the Storage Manager to produce 3.0, 6.0, 9.0 and 12.0 kWh marketed system configurations. The current technical datasheet specifies actual total energy values of 3.1, 6.1, 9.2 and 12.3 kWh respectively.
Because the battery modules are connected in series, system nominal voltage increases with storage capacity from 102.4 V for the single-module system up to 409.6 V for the four-module configuration. This makes correct inverter selection particularly important.
TommaTech specifies 90% depth of discharge, resulting in usable energy ratings from 2.8 to 11.0 kWh. The system provides CAN2.0 communication between battery/BMS components and RS485 / CAN2.0 communication toward the inverter. IP67 protection and operating temperatures down to −30°C are specified in the current technical sheet.
The manufacturer provides a defined compatibility matrix for Uno-Hybrid-K and Trio-Hybrid-K inverter families, meaning battery capacity should always be selected together with the proposed inverter architecture rather than independently.

The datasheet lists Uno-Hybrid-K 3.0T / 3.7T / 5.0T / 6.0T / 7.5T and Trio-Hybrid-K 5.0T / 6.0T / 8.0T / 10.0T / 12.0T / 15.0T within this compatibility matrix.
Technical Architecture
The system contains two technically different components:
Storage Manager Controls and coordinates the high-voltage battery system and inverter communication.
TT 3.0 kWh battery modules One to four modules are connected in series to establish the required energy and DC voltage.
Therefore, the existing CW product listing called “3 kWh Lithium Battery + Storage Management System” is not a separate product family. It is a component/configuration of the same Hightech Power 3.0 architecture.
How It Works
The Storage Manager supervises the battery stack and interfaces with the compatible inverter. Adding battery modules increases system energy while simultaneously increasing system DC voltage.
For example, a single module operates at 102.4 V nominal, while the four-module configuration reaches 409.6 V nominal. The compatible inverter therefore has to support both the battery's communication protocol and the corresponding high-voltage operating range.
