Volnex Alpha 16 51.2V 314Ah Lithium Battery Price in Pakistan

The Volnex Alpha 16 is the biggest battery in the Volnex Alpha series: 51.2V nominal, 314Ah and 16.07 kWh, sold as a 16kW lithium battery. It pairs large-format 314Ah LiFePO4 cells with a single floor cabinet, and Volnex lists a 10-year brand warranty. LiFePO4 needs no water, is safer than NMC chemistry and gives about 90% usable capacity.

Backup at common loads: two fans, lights and a fridge (about 300W) run for about 44 hours. Four fans, eight LED lights and a TV (about 450W) run for about 30 hours. A 1-ton inverter AC with a fan and lights (about 920W) runs for about 14 hours, which is enough for a full summer night. Two ACs at once roughly halve that time; try your own loads in the backup calculator (Battery Backup Calculator).

It suits 48V hybrid inverters such as Growatt, Inverex, Knox, Fronus and Deye, usually in the 6kW to 12kW range. To refill 16 kWh every day you need a solar array to match, so read the sizing guide (What Size Lithium Battery for My Solar System?) before buying. Set the inverter to a lithium or LiFePO4 profile and check BMS communication on the datasheet. The cabinet is floor-standing and heavy, so plan a level indoor spot; no IP rating is listed.

Inside the Volnex line, the Alpha 16 is about three Alpha 5.12 batteries in one cabinet: same 51.2V voltage and the same 10-year warranty, but 314Ah instead of 100Ah. Choose the Alpha 16 for all-night AC and fewer cables. Choose two or three Alpha 5.12 packs if you want to start smaller and add later, or if you need wall mounting. The IP65 Armor 5.12 is the outdoor option, but at 5.12 kWh only. Volnex does not list a cycle figure for the Alpha 16, so check the datasheet for the warranty conditions.

A battery this size changes how a home uses solar. Instead of only covering load shedding, it can store most of a sunny day's surplus and run the house in the evening, which cuts the units drawn from the grid. To get that benefit, the inverter and panels must be large enough to refill it, and the battery should be placed where it stays cool.
