Knox Powerwall 6.1 51.2V 100Ah Lithium Battery Price in Pakistan

The Knox Powerwall 6.1 is a 5kW-class wall battery. It is a 51.2V, 100Ah LiFePO4 pack holding 5.12 kWh. Unlike the 6.0 LCD and the 6.11, our data does not list a cycle rating or warranty period for the 6.1, and the name does not mention a display or an IP rating. So the 6.1 is the plain member of the family: same energy, fewer published extras.

Backup time from full: about 14 hours on 2 fans, lights and a fridge (about 300W), about 9 hours on 4 fans, 8 LED lights and a TV (about 450W), and about 5 hours on a 1-ton inverter AC with a fan and lights (about 920W). These are the same numbers as the 6.0, 6.11 and 7.1, because the capacity is the same. The backup time guide (Lithium Battery Backup Time: How Many Hours Will It Run?) explains how they are worked out.

Compatibility: it is a 48V-class battery for hybrid and off-grid inverters such as Knox, Inverex, Growatt, Fronus and Deye. Set lithium or user mode and confirm BMS communication for your inverter model. It is not for 12V or 24V UPS systems; for those see 24V batteries (24V Lithium Battery).

Installation: wall-mounted, indoor. With no IP rating listed, install it in a dry, shaded room near the inverter and fit a DC breaker between the two.

Life and warranty: not published for the 6.1 in our data. LiFePO4 in general handles thousands of cycles and about 90% usable depth of discharge, but ask us what Knox offers on this model before you order. Our guide on how to check an original lithium battery (How to Check an Original Lithium Battery Before You Buy) is worth reading when you receive it.

A practical tip: since the backup is the same across the Knox 5kW line, your choice comes down to where the battery goes and what paperwork you want. For an indoor wall where you just need dependable night backup, the 6.1 does the same job as its siblings.

Who should buy it? Buyers who want a Knox 5kW wall battery and are happy to confirm the warranty terms at the time of order. If you want a published cycle rating and a display, see the 6.0 LCD. If you want a written 5-year warranty with 6,000+ cycles, the 6.11 is the one. If the battery must go on an outdoor wall, the 7.1 IP65 is built for that. Compare all of them in 5kW batteries (5kW Lithium Battery).
