TE – A2.56 LOW VOLTAGE BATTERY
Categories: LITHIUM ION BATTERIES
The Triex TE-A2.56 is a 2.56kWh wall-mounted LiFePO4 lithium battery designed specifically for 24V off-grid solar systems in Pakistani homes and apartments. Built on LEP LiFePO4 cells in an 8-cell configuration at 25.6V nominal voltage, it delivers 2.3kWh of usable energy at 90% recommended depth of discharge, providing reliable backup power for essential household loads through daily K-Electric and WAPDA outages.
With a cycle life of more than 6000 cycles at 25°C, the TE-A2.56 lasts over 16 years at one cycle per day, eliminating the repeated replacement cost of lead-acid batteries that typically need changing every 2 to 3 years in Pakistan’s daily load shedding conditions. The 5-year product warranty provides additional peace of mind for homeowners making a long-term investment in their solar storage system.
The built-in advanced Battery Management System communicates with compatible inverters through CAN protocol for seamless automatic charge and discharge management. The recommended charge and discharge current of 50A is specifically designed to maximize battery lifetime, while the maximum current of 100A provides flexibility for higher demand situations.
The IP65 ingress protection rating means the TE-A2.56 is protected against dust and low-pressure water jets, making it suitable for installation in covered utility rooms, meter cabinets, and sheltered areas without requiring a completely sealed environment. The compact wall-mounted design fits easily in most Pakistani apartment utility spaces without requiring dedicated floor area.

Who Should Buy This
The TE-A2.56 is the right battery for Pakistani homeowners running a 24V off-grid solar system in a smaller apartment or home. It is the correct match for the Triex Axpert VM II Premium 3kW and Axpert VM IV 4kW inverters, which both use 24V battery systems.
It is ideal for families who want to move from lead-acid batteries to a long-life lithium solution without the complexity or cost of a larger 48V system. For smaller homes where 2.56kWh of storage is sufficient for daily backup needs, the TE-A2.56 provides the most compact, wall-mounted lithium storage solution in the Triex battery lineup.
Compatibility
The TE-A2.56 operates at 25.6V nominal voltage and is designed for 24V battery systems. Compatible Triex inverters include:
- Triex Axpert VM II Premium 3kW PV3000 ✅
- Triex Axpert VM IV 4kW PV5000 ✅
Not compatible with 48V inverters including Triex IP66 6kW, IP66 8kW, Axpert Ultra-Max 8kW, Axpert Ultra-Max 11kW, InfiniSolar V IV 6kW, and Axpert VM IV 6kW. Using this battery with a 48V inverter will damage both the battery and the inverter.
