SolarMax SM-LFP-24100 25.6V 100Ah Lithium Battery Price in Pakistan

The SolarMax SM-LFP-24100 is a 24V wall battery: 25.6V nominal, 100Ah and 2.56 kWh. It takes the place of the pair of 12V tubular batteries in most 24V home systems, with one slim pack fixed to the wall. LiFePO4 cells mean no water top-ups, no acid fumes, a steady voltage under load and about 90% usable capacity.

Backup at common loads: two fans, lights and a fridge (about 300W) run for about 7 hours. Four fans, eight LED lights and a TV (about 450W) run for about 5 hours. A 1-ton inverter AC with a fan and lights (about 920W) runs for about 2 hours. That is a good fit for evening load shedding in a medium home, but not for all-night cooling.

It suits 24V UPS units and 24V solar inverters, including many 3kW 24V hybrid models, as long as the inverter has a lithium or custom LiFePO4 charge profile. Our UPS guide (Lithium Battery for UPS: What Works and What to Check) explains which settings to check. Fix it to a solid indoor wall near the inverter; no IP rating is listed.

In the SolarMax range, this sits between the 12V packs and the 48V wall battery. Compared with the 12V SM-LFP-12100 (1.28 kWh), it stores twice the energy and runs at twice the voltage, so it needs a 24V system. Compared with the SM-LFP-5.12K (51.2V, 5.12 kWh), it has half the energy and is for 24V rather than 48V hybrid inverters. SolarMax has not published a cycle figure or warranty period for the 24100, so ask us for the terms before you order.

When fitting it, the installer removes the old series link between the two tubular batteries and connects the SolarMax pack with two short, thick cables. The inverter menu is then set to a lithium or user battery mode. Check the low-voltage cut-off so the inverter stops before the battery is fully empty, which protects its life. Keep the wall area dry and away from the kitchen or a washing area.

• Best for: 24V UPS or 24V solar inverter homes, 4 to 7 hours of fan and light backup
• Look elsewhere if: you have a 48V hybrid inverter or want hours of AC (see the 48V batteries (48V Lithium Battery))
• Compare all 24V packs: (24V Lithium Battery)
