Knox vs Inverex Lithium Battery: Which One Should You Buy?
Knox vs Inverex is one of the most searched lithium battery comparisons in Pakistan, because both are large local brands that sell inverters and batteries together. Both use China-made LiFePO4 cells. This page compares their ranges size by size using the specs in our catalogue (cycles, warranty, protection rating and mounting), then explains which brand suits which buyer.

12V and 24V (UPS sizes)
- Inverex 12V 100Ah (1.28 kWh) and 12V 200Ah IP21 (2.56 kWh): box batteries for 12V UPS. Knox has no 12V model in our catalogue.
- Inverex INV 2.5 Power Wall 24V: 2.56 kWh, 4,000 cycles, IP21, wall-mounted.
- Knox Powerwall 3.0 LCD and 3.1 (24V): 2.56 kWh, 6,000 cycles listed, wall-mounted. The 4.15 is another 24V 100Ah option.
For a 12V UPS, Inverex is the only one of the two here. For 24V, Knox lists higher cycles. See 24V batteries (24V Lithium Battery).
5kW class (48V 100Ah)
- Knox Powerwall 6.11: 5.12 kWh, 6,000+ cycles, 5-year warranty.
- Knox Powerwall 6.0 LCD: 5.12 kWh, 6,000 cycles.
- Knox Powerwall 7.1: 5.12 kWh, IP65.
- Inverex LV IP21 5.1: 5.12 kWh, 6,000 cycles, IP21.
- Inverex LV5.3 IP65: 5.3 kWh (104Ah), 6,000 cycles, 10-year warranty, IP65.
- Inverex LV5.3 111Ah: 5.7 kWh, the largest in this class.
Inverex offers slightly more kWh in some 5kW models and the longest listed warranty; Knox offers the most models with published cycle and warranty figures. See 5kW batteries (5kW Lithium Battery).
10kW and 16kW classes
- Knox Rackwall 8.7: 7.68 kWh (150Ah), rack.
- Knox Rackwall 10.5: 10.24 kWh, 6,000 cycles, rack.
- Knox Powerbase 10.5: 10.5 kWh, 8,000+ cycles, 5 years, floor-standing.
- Inverex LV P21 11.8: 11.8 kWh (230Ah), 6,000 cycles, IP21, floor.
- Knox Rackwall 15: 14.3 kWh (280Ah).
- Knox Powerbase 16.0: 16.07 kWh (314Ah), 8,000+ cycles, 5 years.
- Inverex LV IP21 16: 16.07 kWh (314Ah), IP21.
- Knox Powerbase 32: 32.15 kWh, 8,000+ cycles, 5 years.
In the large sizes Knox has more choices and higher cycle ratings; Inverex's 11.8 kWh sits between the usual 10kW and 15kW steps.
Inverter pairing
Both brands sell hybrid inverters and their batteries pair most easily with their own inverters. Neither publishes a public compatibility list for other inverter brands. If you have a Deye, Growatt or another brand, ask the seller to confirm communication for your exact model, or run the battery in voltage mode with the maker's settings. See the settings guide (Lithium Battery Settings for Growatt, Deye, Inverex and Knox).
Both brands' 48V batteries are 51.2V, 16-cell packs, so in voltage mode the general safe values for 16-cell LiFePO4 apply: bulk or absorption 56.0 to 56.8V, float 54.0 to 54.4V and low cut-off 48 to 50V. Always check the battery maker's sheet first.
Wall, rack or floor: mounting options
- Knox Powerwall models (24V and 5kW) are wall-mounted, which saves floor space in small homes.
- Knox Rackwall models (7.68, 10.24 and 14.3 kWh) are rack units for cabinets or stacking.
- Knox Powerbase models (10.5, 16.07 and 32.15 kWh) are floor-standing.
- Inverex 12V batteries are box type; the 24V and 5kW models are wall-mounted; the 11.8 kWh and 16 kWh models are floor-standing.
If you want a rack system to grow over time, Knox has more choice. If you want one simple wall unit, both brands offer several. See wall-mounted batteries (Wall Mounted Battery).
Protection rating: IP21 vs IP65
Several Inverex models list IP21, which means basic protection against touch and dripping water: keep these indoors in a dry place. The Inverex LV5.3 IP65 and Knox Powerwall 7.1 IP65 are sealed against dust and water jets, so they suit garages, verandas and dusty areas, though they should still be kept out of direct sun. Many Knox models do not list an IP rating in our catalogue; treat them as indoor batteries unless the datasheet says otherwise. See IP65 batteries (IP65 Lithium Battery).
Which should you buy?
- You have an Inverex inverter, or need a 12V UPS battery: Inverex.
- You have a Knox inverter, or want 8,000-cycle large batteries or a 30kW class unit: Knox.
- You need an outdoor battery: Inverex LV5.3 IP65 or Knox Powerwall 7.1 IP65.
- You want the longest written warranty in the 5kW class: Inverex LV5.3 IP65 (10 years listed).
Prices change daily, so compare the live price on each product page before deciding.
If you already own one brand's inverter, buying the same brand's battery keeps communication simple and puts both under one service network.
