Knox Inverter Price in Pakistan 2026
Knox inverter price in Pakistan ranges from Rs. 79,000 for a basic Argon 3kW off-grid unit to Rs. 375,000 for the flagship Zynex 10kW IP66 hybrid, as of August 2026. Knox is manufactured by Voltronic Power (Taiwan) and locally assembled with a dealer network across Lahore, Karachi, Islamabad, and Multan. Prices vary by city, dealer margin, and whether you buy with or without a battery bundle.
Knox currently sells four inverter series Krypton, Krypton ECO, Xenon, and Zynex plus the Argon off-grid line and Xerox G4 Pro on-grid range. Each targets a different buyer and budget. The tables below cover every model with dealer-verified pricing.
Knox Hybrid Inverter Prices Krypton Series (August 2026)
The Krypton series is Knox’s core residential line. All models feature dual output for smart load management, built-in WiFi monitoring, MPPT solar charge controllers, and support for batteryless operation. The newer RGB models (8.5kW and above) include a 7-inch HMI touchscreen display and built-in BMS for lithium batteries.
| Model | Power / PV | Battery | Type | Price | ECO / RGB Option |

Price note: Prices are dealer-verified reference rates for August 2026, cross-checked against Volteck, w11stop (authorized distributor), and Kamal Solar listings. Final price depends on dealer margin, city, and whether the inverter is bundled with a Knox lithium battery. Verify with your local dealer before purchase.
The Krypton ECO sub-series (ECO-4000, ECO-5000, ECO-6600) is the budget entry point single MPPT, no touchscreen, but fully capable of grid feeding and batteryless operation. The standard Krypton 6000/6500 adds dual output at 24V. The RGB models (9000 and above) are the premium tier with touchscreen, dual MPPT, built-in BMS, and WiFi.
For a residential setup running a 1.5-ton inverter AC, 8–10 fans, LED lights, and a fridge, the Krypton 9000 RGB (6.2kW) is the most commonly installed model we track. It handles this load comfortably — but only if your solar panel array is correctly sized to match its 9,000W PV input capacity.
Knox Zynex Series Premium IP66 Hybrid (August 2026)
The Zynex is Knox’s flagship 2026 line. Three independent MPPTs, IP66 dust and water protection (suitable for outdoor installation), UPS-level switching under 10ms, and support for up to 200% PV oversizing. These are built for larger homes and commercial setups.
| Model | Rated Output | Max PV Input | MPPTs | IP Rating | Price (PKR) |
|---|---|---|---|---|---|
| Zynex ZX-3M-0816 | 8kW | 16,000W | 3 | 345,000 – 375,000 | |
| Zynex ZX-3M-1020 | 10kW | 20,000W | 3 | 375,000 – 420,000 |
Series note: Zynex pricing runs 30–40% higher than equivalent-capacity Krypton models, but you get three MPPTs (better shade handling and flexible panel placement), IP66 weatherproofing, ShadeSol shadow management technology, and expandability up to 30kW by paralleling units. Compatible with both lithium (LiFePO₄) and lead-acid batteries.
For a home running 2+ inverter ACs, a water pump, and a full kitchen load, the Zynex 8kW with a proper 16kW panel array is the right fit. The 10kW model is overkill for most residential setups — it targets light commercial (shops, offices, small factories).
Knox Xenon and Argon Series (August 2026)
| Model | Rated Output | Type | Max PV Input | IP Rating | Price (PKR) |
|---|---|---|---|---|---|
| Xenon 12066 | 6kW | Hybrid On/Off-Grid | 12,000W | 235,000 – 265,000 | |
| Argon VM II PV4000 | 3kW | Off-Grid | 4,000W | 79,000 – 95,000 | |
| Argon VM II PV6000 | 5kW | Off-Grid | 6,000W | 105,000 – 120,000 |
The Xenon 12066 sits between the Krypton and Zynex lines — it offers IP66 weatherproofing and dual MPPT at a lower price point than the Zynex. Good fit for buyers who want outdoor mounting capability without the Zynex premium.
The Argon VM II series is Knox’s budget off-grid option. No grid feeding, no net metering, no WiFi — but reliable pure sine wave output for basic solar backup. At Rs. 79,000 for the 3kW model, it’s the cheapest Knox solar inverter available.
Knox On-Grid Inverters Xerox G4 Pro Series (August 2026)
If net metering is your primary goal, Knox offers the Xerox G4 Pro line three-phase on-grid inverters designed for commercial-scale installations. These do not support batteries or off-grid backup.
| Model | Capacity | Phase | Efficiency | Price (PKR) |
|---|---|---|---|---|
| Xerox G4 Pro | 10kW | 3-Phase | 98.4% | PKR 169,000 10.2K: PKR 195,000 |
| Xerox G4 Pro | 30kW | 3-Phase | 98.6% | PKR 327,000 30K: PKR 360,000 |
| Xerox G4 Pro | 40.5kW | 3-Phase | 98.6% | PKR 405,000 40.5K: PKR 440,000 |
| Xerox G4 Pro | 50kW | 3-Phase | 98.6% | PKR 432,000 50K: PKR 470,000 |
G4 Pro note: These are pure on-grid inverters with IP66 protection, WiFi/GPRS monitoring, and up to 150% PV oversizing. Ideal for commercial rooftop net metering projects. Residential single-phase buyers should look at the Krypton or Zynex hybrid series instead.

Comparison note: Prices verified across Lahore Hall Road and Islamabad College Road dealers, August 2026. Knox sits mid-range on price but carries a shorter warranty than Chinese brands like Growatt (5 years) and Solis (5 years). For a 3kW solar system buyer on a tight budget, the Knox Argon or Krypton ECO is a workable entry point but verify your dealer has a physical service centre, not just a mobile number.

City price note: Lahore remains the cheapest market for Knox inverters. If you’re in Multan, Faisalabad, or Karachi, call a Lahore-based authorized dealer for shipped pricing plus transport the savings often cover the shipping cost.
Knox Lithium Battery Prices Powerwall Series
Knox now sells its own LiFePO₄ batteries under the Powerwall brand. These pair directly with all Krypton (built-in BMS on RGB models), Xenon, and Zynex inverters.
| Model | Voltage | Capacity | Price (PKR) |
|---|---|---|---|
| Powerwall 3.0 | 25.6V / 100Ah | 2.56 kWh | 126,000 – 140,000 |
| Powerwall 3.1 | 25.6V / 100Ah | 2.56 kWh | 133,000 – 145,000 |
| Powerwall 4.15 | 51.2V | 4.15 kWh | 142,000 – 160,000 |
| Powerwall 6.0 | 51.2V / 100Ah | 5.12 kWh | 225,000 – 250,000 |
| Powerbase 16.0 | 51.2V | 16 kWh | 540,000 – 600,000 |
The Powerwall 3.0 pairs with the Krypton ECO-4000 (24V system). The Powerwall 6.0 pairs with any 48V Knox inverter Krypton 9000 and above, Xenon, or Zynex. Up to 8 Powerwall units can be paralleled for larger storage banks. For buyers comparing lead-acid alternatives, check our Osaka battery price and Phoenix battery price pages.
Knox Warranty, After-Sales
Knox warranty terms vary by series not a flat number across all products:
| Series | Warranty | Service Centre Availability |
|---|---|---|
| Krypton ECO Dealer-dependent | 1–2 years | Lahore, Karachi, Islamabad |
| Krypton 6000/6500 | 2 years | Lahore, Karachi, Islamabad |
| Krypton RGB 9000+ | 3 years | Lahore, Karachi, Islamabad |
| Xenon | 2 years | Lahore, Karachi |
| Zynex | 2–3 years | Lahore, Karachi, Islamabad |
| Argon | 1 year | Limited |
| Xerox G4 Pro | 5 years | Dealer-dependent |
Knox has authorized service centres in Lahore, Karachi, and Islamabad but dealer level service quality varies outside these cities. We’ve tracked parts sourcing delays of 35 weeks for PCB replacements in Peshawar and Faisalabad.
The Honest Verdict: Knox inverters are a solid mid-budget choice for hybrid solar setups where flexibility matters batteryless operation, dual output, and WiFi monitoring give real practical value. The Zynex series competes credibly with premium Chinese brands on features. The weakness is warranty: even with 3 years on Krypton RGB models, Growatt and Solis still offer 5 years standard. For a pure net-metering investment focused on long-term ROI, the warranty gap matters. If Knox is your pick, buy only from an authorized dealer who provides a printed invoice with serial number and a registered warranty card.
Does a Knox System Make Financial Sense?
A 6kW Knox Krypton 9000 RGB system paired with a quality solar panel array costs roughly Rs. 620,000–850,000 all-in (inverter + panels + mounting + wiring + labour), excluding batteries. Add a Knox Powerwall 6.0 for battery backup and the total reaches Rs. 850,000–1,100,000. See our 8kW solar system page for a full component cost breakdown.
With a monthly electricity bill above Rs. 12,000–15,000, self-consumption savings make this viable over 4-5 years. Export credits under the current NEPRA net billing framework (approximately PKR 11 13/unit as of mid-2026) are significantly lower than the retail rate meaning systems designed primarily around self-consumption pay back faster than export-heavy designs.
Knox Inverter Maintenance and Troubleshooting
Three issues come up repeatedly with Knox inverters, tracked across dealer feedback:
Overtemperature Shutdowns
Keep 15–20cm clearance around the inverter and avoid direct sunlight on the casing.
Krypton models are IP21 indoor-only. If installed outside, overheating is expected.
Battery Not Charging Fully
For Knox 48V models with tubular batteries, set 58.4V bulk and 54.0V float.
For Knox Powerwall LiFePO4, use the preset lithium profile.
Grid Transfer Failures
On hybrid models, check the AC output wiring polarity. Reversed live and neutral can damage the transfer relay.
This is usually an installer mistake, not a product defect.
Where to Buy Knox Inverters in Pakistan
Final Thoughts
Knox is not the cheapest brand and not the most reliable long-term pick but it offers the widest product flexibility in its price range. Batteryless operation, dual output, lithium and lead-acid support, and a lineup from Rs. 79,000 to Rs. 420,000 make it the most versatile mid-budget option in Pakistan. For a 6kW home setup between Rs. 150,000 and Rs. 200,000, the Krypton 9000 RGB remains hard to beat on value.
The weakness is warranty and after-sales outside major cities. Growatt and Solis still offer 5 years standard where Knox gives 1–3 years on most models. Knox has recently extended warranty to 5 years on IP65/IP66 units through authorized dealers confirm this in writing before purchase. Buy only from authorized dealers with a serial-number invoice and registered warranty card.
