CoreTECH CT-5120 Pro 5.12kWh LiFePO4 Battery
CoreTECH is a Karachi based solar brand, and the CT-5120 Pro is its 5.12kWh lithium battery for the everyday 48V home system. It uses LiFePO4 chemistry at a nominal 51.2V DC and 100Ah, and it can discharge at up to 100A, which gives a 48V hybrid inverter plenty of current to run lights, fans, a fridge and a few heavy loads together. A round-trip efficiency of more than 95% means very little of the energy you store is lost when you take it back out. A smart battery management system guards the cells, and connectivity options let you monitor the battery. The compact pack can be rack mounted or wall mounted, so it fits a utility room or cabinet without taking much space. It is listed with a 6000 cycle rating and an IP21 indoor rating.

- Anyone building a UPS backup or an off-grid system
Why Round-Trip Efficiency Matters
Round-trip efficiency compares the energy you take out of a battery with the energy you put in. If a battery is 95% efficient, then storing 5kWh gives you about 4.75kWh back, while a less efficient battery gives you less. Over years of daily use the difference adds up to a lot of solar energy that you either use or waste. LiFePO4 batteries are generally more efficient than lead acid, and a figure above 95% means this one does its job with little loss.
CoreTECH LiFePO4 Battery - Compatibility and Installation Guide
- Match it with a 48V class hybrid inverter that supports lithium batteries and check its compatibility list
- Install indoors in a dry, ventilated place because the rating is IP21
- Use correctly sized cables and check polarity on every connection
- Plan the rack or wall bracket for the weight of the unit
- Follow the manual for monitoring connection and commissioning
- Installation should be done by a qualified solar installer
