Knox Powerwall 7.1 IP65 51.2V 100Ah Lithium Battery Price in Pakistan

The Knox Powerwall 7.1 IP65 holds the same 5.12 kWh as the Knox 6-series (51.2V, 100Ah, LiFePO4), but its case is rated IP65. That means it is dust-tight and protected against jets of water, which matters in dusty Pakistani cities and in homes where the only free wall is outside. Our data does not list a cycle count or warranty period for the 7.1.

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 numbers match the other Knox 5kW batteries because capacity is the same; the 7.1 adds protection, not hours.

Compatibility: it is a 48V-class battery for 48V hybrid and off-grid inverters from Knox, Inverex, Growatt, Fronus and Deye. Set lithium or user mode and confirm BMS communication. If the inverter is indoors and the battery outdoors, keep the DC cable run short and sized for the current.

Installation: IP65 allows mounting on a covered veranda, garage, rooftop room wall or outdoor wall. Even so, avoid direct afternoon sun, because heat above normal room temperature shortens any lithium battery's life. A shade cover or a north-facing wall is ideal. See more IP65 lithium batteries (IP65 Lithium Battery) and wall-mounted lithium batteries (Wall Mounted Battery).

Life and warranty: not published for this model in our data. Ask us before ordering what Knox offers on the 7.1, and check the datasheet.

A practical tip: before you mount any battery outside, check that the wall can carry the weight and that rain will not pool around the cable entry. Use a proper outdoor cable gland and keep the DC breaker in a covered box, because IP65 protects the battery case, not your wiring.

How it compares with the 6-series: the 6.0 LCD and 6.11 list 6,000+ cycles, and the 6.11 lists a 5-year warranty, but neither lists an IP rating, so they are indoor batteries. The 7.1 is the only one of the four with a published outdoor-grade rating. If your battery will sit indoors, the 6.11 gives you more published facts; if it has to go outside, the 7.1 is the right Knox choice. Compare in 5kW batteries (5kW Lithium Battery).
