SolarMax SM-LFP-5.12K 51.2V 100Ah Lithium Battery Price in Pakistan

The SolarMax SM-LFP-5.12K is a 48V wall-mounted lithium battery: 51.2V nominal, 100Ah and 5.12 kWh, the size most Pakistanis search for as a 5kw lithium battery or 48v 100ah. It is the largest model in the SolarMax group listed here. Its LiFePO4 cells need no water, are safer than NMC lithium and give about 90% usable capacity.

Backup at common loads: two fans, lights and a fridge (about 300W) run for about 14 hours. Four fans, eight LED lights and a TV (about 450W) run for about 9 hours. A 1-ton inverter AC with a fan and lights (about 920W) runs for about 5 hours. With solar charging during the day, it can carry a typical home through the evening and most of the night.

It suits 48V hybrid and off-grid inverters such as Growatt, Inverex, Knox, Fronus and Deye. Set a lithium or LiFePO4 profile, and check the datasheet for BMS communication with your inverter. The compatibility guide (Which Lithium Battery Works With My Inverter?) explains what to match. Mount it indoors on a solid wall near the inverter, away from direct sun; no IP rating is listed.

How it compares inside SolarMax: the SM-LFP-24100 is the 24V wall model with half the energy (2.56 kWh), and the 12100 packs are 12V for single-battery UPS units. The 5.12K is the one to choose if you have, or plan to buy, a 48V hybrid solar inverter. SolarMax has not published a cycle figure or warranty period for the 5.12K, so ask us for the terms before ordering. If a published cycle rating matters to you, compare it with other 5kW packs that list one.

Who should buy it? A family moving from tubular batteries to a new 48V hybrid inverter who wants one 5kW lithium battery on the wall. It also suits a small office that needs fans, lights, computers and Wi-Fi during load shedding. Who should look elsewhere? Homes with a 24V inverter, which need the SM-LFP-24100 instead, and homes that want all-night AC, which need a 10kW or larger battery. Before you order, note your inverter brand and model so we can check the battery settings. Keep the invoice safe for any warranty claim.
