TommaTech Trio Hybrid S HV AIO CMS CONTENT PACK
The TommaTech Trio Hybrid S HV AIO Series integrates a three-phase hybrid inverter and a modular high-voltage battery system into a unified residential energy storage platform.
Seven inverter ratings are available: 5, 6, 8, 10, 12, 15 and 20 kW. Unlike the LV AIO family, the HV platform uses a series-connected battery architecture based on TommaTech Hightech Power S 4 kWh HV modules. Two to six modules can be assembled into battery configurations ranging from 8 to 24 kWh nominal energy, with 7.2 to 21.6 kWh listed as usable energy under the manufacturer's stated test conditions.
The high-voltage battery architecture allows the system to operate at substantially higher DC battery voltage, reducing current for a given power level compared with a low-voltage architecture. The inverter accepts PV input, manages battery charging and discharging and interfaces with grid, backup loads and generator systems. The official documentation also provides AC coupling, Smart Load, time-of-use management, Wi-Fi monitoring and parallel-system functionality.
The current datasheet states that up to ten HV AIO inverter units may be connected in parallel and highlights three-phase unbalanced output capability.
Because 5–20 kW versions use the same underlying platform, they should be presented as one configurable HV AIO family rather than seven separate website products.

Technical Architecture
The HV AIO platform consists of a three-phase hybrid inverter mounted above or integrated with a vertically stacked battery system.
Each battery module contributes 102.4 V and 4 kWh. The modules are connected in series, so adding modules increases both system voltage and stored energy. This produces nominal system voltages from 204.8 V with two modules up to 614.4 V with six modules.
The inverter connects separately to:
- PV strings
- High-voltage battery stack
- Utility grid
- Backup load
- Generator input
- Meter/CT
- BMS
- Parallel communication
- Wi-Fi / monitoring services
This series-connected battery topology is the major engineering distinction between the HV and LV AIO families.
How It Works
PV power is first managed by the inverter's MPPT stage. Depending on instantaneous load, battery state of charge and programmed operating strategy, energy can be supplied to the loads, stored in the HV battery or exported according to the applicable grid configuration.
When solar generation is insufficient, the battery can supply the loads through the hybrid inverter. Grid or generator power can also be incorporated according to system settings and charging priority.
The official system architecture supports grid, PV, generator, backup load and smart-load configurations, together with cloud-connected monitoring.
Intended Applications
- Residential solar energy storage
- Large residential properties
- Three-phase residential systems
- Residential backup systems
- Solar self-consumption
- Grid-interactive hybrid PV systems
- Generator-supported energy storage
- Applications requiring higher inverter power with lower battery-side current than a comparable LV architecture
The final statement is an engineering consequence of the higher-voltage architecture, rather than a manufacturer marketing specification.
Compatibility
Official documentation supports integration with:
- Hightech Power S 4 kWh HV battery system
- PV arrays
- Utility grid
- Backup loads
- Generator supply
- AC coupling
- Smart Load
- Meter / CT
- CAN / RS485 battery communication
- Wi-Fi monitoring
Do not publish a general statement that the system works with arbitrary third-party high-voltage batteries.
Engineering and Selection Notes
HV system selection must consider both inverter power and battery voltage configuration.
Before selecting the system, verify:
- Maximum continuous AC load
- Peak/starting load
- Phase imbalance
- Backup-load requirement
- Required battery autonomy
- Daily energy demand
- Required charge/discharge power
- Selected number of HV battery modules
- Resulting battery nominal voltage
- Inverter battery operating voltage
- PV module Voc
- Minimum site temperature
- PV string voltage under operating conditions
- Full-load DC voltage requirement for the selected inverter
- PV Isc and operating current
- Grid voltage/frequency
- Applicable grid code
- Generator capacity
- Installation temperature
- Outdoor/indoor installation requirements
- Expansion requirements
- Parallel inverter requirement
Particularly important
The increasing full-load PV voltage requirement as inverter power rises should not be ignored. For example, the 20 kW model requires a much higher full-load DC string voltage than the 5 kW model.
Therefore PV string design must be carried out using the actual module Voc/Vmp and minimum ambient temperature.
