Knox Powerbase 32 51.2V 628Ah Lithium Battery Price in Pakistan

The Knox Powerbase 32 is a 30kW-class battery with a true capacity of 32.15 kWh. It is a 51.2V system with 628Ah of LiFePO4 capacity, which is double the Powerbase 16.0. It is floor-standing, rated for 8,000+ cycles and carries a 5-year brand warranty.

Backup time from full: about 89 hours on 2 fans, lights and a fridge (about 300W), about 59 hours on 4 fans, 8 LED lights and a TV (about 450W), and about 29 hours on a 1-ton inverter AC with a fan and lights (about 920W). Real users of a battery this size run several ACs, a fridge, a water pump and office loads, so think in total watts: for example, 3kW of load runs for roughly 9 hours (32.15 x 0.9 x 0.92 x 1000 / 3000). The backup calculator (Battery Backup Calculator) does this for you.

Compatibility: it is a 48V-class battery for 48V hybrid and off-grid inverters from Knox, Inverex, Growatt, Fronus and Deye. It is best with a 10kW or larger inverter, or two inverters in parallel, so that it can charge and discharge fast enough. Confirm BMS communication, charge current and the number of inverters it can serve with Knox or us before ordering.

Installation: this is a large, heavy floor unit. Plan a dedicated dry, shaded room with a strong, level floor, good air flow and space for service. No IP rating is listed, so it is an indoor battery. Use heavy DC cable, a correctly rated DC breaker and a qualified installer.

Life and warranty: 8,000+ cycles at one cycle a day is over 20 years on paper, and the 5-year brand warranty gives a clear support period.

A planning tip: to refill 32 kWh from solar in a day you need roughly 8kW of panels for the battery alone, since 1kW makes about 4 units a day in Pakistan, plus panels for your daytime load. Most buyers of this size pair it with a 15kW or larger array.

Who should buy it? Large homes with two or more ACs at night, offices, clinics and shops that need many hours of backup, and anyone with a 15kW or bigger solar array who wants to store most of the day's output. Smaller homes will get better value from a 16kW battery (16kW Lithium Battery). Compare other big batteries in 30kW batteries (30kW Lithium Battery) and see complete solar packages (All Solar Systems).
