TommaTech Hightech Power S Series HV Battery System
The TommaTech Hightech Power S Series HV Battery System is a modular high-voltage energy storage platform developed primarily for residential solar energy storage and hybrid power applications.
The architecture is based on a 4 kWh lithium battery module rated at 102.4 V and 40 Ah. Multiple modules are connected in series to create complete AIO-S system configurations ranging from 8 kWh to 24 kWh. Increasing the number of modules increases both the system energy and nominal DC voltage while retaining a common platform architecture.
Available configurations use two to six battery modules, resulting in nominal system voltages from 204.8 V to 614.4 V. Usable DC energy ranges from 7.2 kWh to 21.6 kWh under the manufacturer's specified test conditions. The system incorporates battery management functionality, LCD-based operating information and CAN2.0 / RS485 communication interfaces.
The platform is designed for floor-mounted installation and carries an IP65 enclosure rating. TommaTech states an operating temperature range of −20°C to +55°C for both charging and discharging and recommends a 90% depth of discharge. The manufacturer's current documentation specifies a lifecycle of at least 6,000 cycles under defined laboratory conditions and a 10-year warranty, subject to the manufacturer's lifecycle and warranty conditions.
TommaTech identifies the system as compatible with its Trio Hybrid S HV Series inverters. Exact inverter model selection, system voltage window and project configuration should therefore be verified before quotation rather than selecting the battery purely by energy capacity.

Technical Architecture
Each system uses the same 4 kWh / 102.4 V battery module platform. The required system energy is achieved by increasing the number of modules connected in series, rather than by changing the basic cell platform.
This means the capacity selection simultaneously changes the system DC voltage:
2 modules → AIO-S8 → 204.8 V
3 modules → AIO-S12 → 307.2 V
4 modules → AIO-S16 → 409.6 V
5 modules → AIO-S20 → 512 V
6 modules → AIO-S24 → 614.4 V
The BMS manages the battery system while CAN2.0 / RS485 interfaces provide communication functions.
How It Works
During solar generation or grid-supported charging, the compatible hybrid inverter transfers energy to the battery system. The BMS supervises operation and the connected series battery modules operate together as one high-voltage DC storage system.
When stored energy is required, the battery supplies DC energy back to the compatible hybrid inverter, which manages conversion and distribution to the electrical loads.
Increasing battery capacity therefore means adding series-connected 4 kWh modules within an approved system configuration rather than simply connecting independent batteries in parallel.
Intended Applications
- Residential photovoltaic energy storage
- Solar self-consumption systems

Compatibility
Officially stated: TommaTech Trio Hybrid S HV Series inverters.
Exact inverter model, firmware and battery configuration should be confirmed for the proposed project before quotation.
Engineering and Selection Notes
Before selecting AIO-S8 through AIO-S24, the project engineer should evaluate:
- Required usable storage capacity
