What is TommaTech 3 kWh Lithium Battery + Storage Management System?
This product is a 3.1 kWh battery module used with high-voltage hybrid inverters and includes the storage management system (BMS). It is designed to store surplus energy produced from solar power and use it in the evening hours or during a grid outage. The supplier states that up to 3.0 of the TT-4kWh cells can be equipped with a BMS.

Which projects is it suitable for?
It can be used in high-voltage hybrid systems for homes, villas and small commercial businesses. Thanks to its small capacity, it suits projects that want to start with storage at a low initial investment and add modules later.
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
Since the sun is abundant in Antalya for most of the year, shifting the daytime surplus to evening use is the most efficient way to use a battery. IP65 protection and the charge/discharge range between -30°C and 55°C give flexibility in a hot climate; even so, the battery should be placed away from surfaces that receive sun. Solar Nexo verifies inverter compatibility and cabling during installation.
From supply of the product through project design, installation, commissioning and subsequent technical support, Solar Nexo handles the whole process in Antalya from a single source. You can download the product datasheet from this page.
