What is TommaTech Modular Series 25.6 V 204 Ah G2 Lithium Battery?
TommaTech Modular Series 25.6 V 204 Ah G2 Lithium Battery is a metal-cased, compact energy storage module from the supplier's modular lithium battery family. Multiplying 25.6 V by 204 Ah gives a nominal energy of about 5.22 kWh; the datasheet should be the reference for the real usable energy. This model is for 25.6 V systems and is the voltage class of the series that offers Bluetooth communication support.
Key technical specifications
- Nominal voltage / capacity: 25.6 V / 204 Ah
- Cycle life: up to 8000 cycles
- BMS: with active balancing
- Parallel connection: up to 16
- Communication: CAN / RS485 / Bluetooth (Bluetooth only on 25.6 V batteries)
- Protection class: IP20-IP65 compatible metal case and terminals
- Warranty: 5-year product warranty
Which projects is it suitable for?
Suitable applications: 24 V class systems, caravans, boats and small backup power applications, as well as storage packages. Capacity can be expanded over time by adding modules in parallel; because it can be charged from solar panels, it is also used in systems that increase self-consumption.
For correct sizing, the electricity bill and the appliance list are reviewed first; then the storage capacity, inverter power and number of parallel connections are determined. If this order is not followed, the battery either falls short or becomes a larger investment than needed.
Use in Antalya and Solar Nexo support
In Antalya, the air-conditioning load on summer evenings is when storage is most useful. Although the metal case is described as heat resistant, the battery should not be placed on a hot wall surface or in an area that gets direct sun.
For its customers in Antalya, Solar Nexo supplies the product, designs it to suit the system, installs and commissions it, and provides technical support afterwards. The relevant datasheet is ready to download on this page.
