TXL-5.12 LOW VOLTAGE BATTERY
Categories: LITHIUM ION BATTERIES
The Triex TXL-5.12 is a 5.12kWh wall-mounted LiFePO4 lithium battery designed for residential hybrid solar systems across Pakistan. Built on LFP 3.2V 100Ah cells in a 16S1P configuration, it delivers 4.86kWh of usable energy at 90% depth of discharge, giving Pakistani homes reliable backup power through daily K-Electric and WAPDA outages without the maintenance and replacement burden of lead-acid batteries.
With a cycle life of 6000 or more at 70% end of life and 80% depth of discharge, the TXL-5.12 outlasts lead-acid batteries by 4 to 6 times under Pakistan’s real-world daily cycling conditions. A family using one charge and discharge cycle per day can expect over 16 years of consistent performance, making it one of the most practical entry-level lithium storage options available for Pakistani solar systems.
The built-in advanced Battery Management System monitors cell voltage, temperature, current, and state of charge continuously. It communicates with compatible hybrid inverters through CAN and RS485, enabling fully automatic charge and discharge management. Up to 16 units can be connected in parallel, scaling the total storage capacity to 81.92kWh for larger homes or small commercial setups that need more backup time.
The compact wall-mounted or floor-mounted design fits easily in a utility room, meter cabinet, or covered area, keeping the installation clean and organized without requiring dedicated floor space in most cases.
Product Description
Key Features

Who Should Buy This
The TXL-5.12 is the right starting point for Pakistani homeowners who want to move from lead-acid to lithium storage without a large upfront investment. It is ideal for homes in Karachi, Lahore, and other cities with 4 to 8 hours of daily load shedding that need enough stored energy to run fans, lights, refrigerator, and router through a standard outage window.
If you are installing a new hybrid solar system or upgrading an existing one, the TXL-5.12 delivers the reliability and lifespan that lead-acid batteries cannot match, at a capacity that suits most medium-sized Pakistani homes. Multiple units can be added later as your power needs grow, making it a flexible long-term storage solution.
