What is the TommaTech Modular High-Voltage Energy Storage System?
This product is a high-voltage lithium battery system in which the desired capacity is reached by stacking modules on top of one another in a rack. Capacity starts at 25.6 kWh and grows up to 81.92 kWh; modules can be added as needs increase. The supplier states that the system is optimized to work in full compatibility with the TommaTech Maxi Series M50K and M80K hybrid inverter models.
Key technical features
- Capacity range: 25.6 kWh – 81.92 kWh
- Cycle life: ≥6000 (0.5C, 70% EOL)
- Operating temperature: -20°C to 55°C
- Parallel expansion: up to 16 modules
- Communication: CAN2.0 and RS485
- Software update: USB or remote
- Protection class: IP20, indoor
- Protection: overcharge, over-discharge, over-temperature, overcurrent
- Low self-discharge: can be stored for up to 6 months without charging
Which projects is it suited for?
It is suited for medium and large-scale businesses, hotel and facility rooftop solar plants, agricultural processing facilities and commercial buildings that want to increase their self-consumption. Because the rack-type structure saves floor space, it is a practical solution for projects where a separate panel or machine room can be allocated.
For correct sizing, the electricity bill and the list of appliances 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 turns into a larger investment than necessary.
Use in Antalya and Solar Nexo support
In Antalya, production and consumption hours may not match: solar plants peak in the middle of the day while hotel and business consumption rises in the evening. Because of the IP20 protection class, the system must be installed in an enclosed, dry and ventilated room; taking summer heat and coastal humidity into account, the room conditions are assessed by Solar Nexo during the site survey.
The Solar Nexo team is with you from selection to on-site installation, from commissioning to after-sales technical support; it carries out site surveys and prepares quotes for projects in Antalya and the surrounding area. You can download the datasheet on the page for technical details.
