Solar Inverter Price in Pakistan 2026 — Inverex, Knox, Crown, Solis Hybrid Guide
Pakistan installed an estimated 8.2 GW of solar in 2025 — more than the previous 10 years combined. Behind every install sits an inverter, and the inverter choice determines whether the system delivers the 25-year payback the marketing brochure promised or fails at year 6 from heat-derating mid-summer. Get the brand, topology (string vs hybrid vs micro), and rating right and the inverter outlasts the panels. Get it wrong and you'll be re-buying within the warranty period.
This guide covers solar inverter prices in Pakistan for 2026, the hybrid vs off-grid vs on-grid distinction, sizing for 3–15 kW systems, and the matching DC + AC protection from CNC that NEPRA 2026 requires around the inverter.
1. Hybrid vs Off-Grid vs On-Grid — pick the right topology first
| Type | What it does | Battery? | Grid export? | Best for |
|---|---|---|---|---|
| On-Grid (grid-tied) | PV → inverter → house + grid export | No | Yes | Net-metering customers, no battery |
| Off-Grid | PV + battery → inverter → isolated house | Mandatory | No | Remote rural areas, no grid |
| Hybrid | PV + battery + grid → inverter → house, can export | Optional | Yes (when net-metered) | Pakistani residential — most popular today |
For 90% of Pakistani residential installs in 2026, hybrid is the right choice. It runs grid-tied for tariff-rate buyback when sun is good, switches to battery during outages, and falls back to grid when battery is depleted.

For Pakistani residential 5-8 kW hybrid, the price sweet spot is PKR 200,000-300,000. Brand premium (Solis, Fronius) buys longer warranty + better efficiency at the cost of 30-50% higher upfront.
3. How to size a solar inverter for your Pakistani home
- Calculate your peak load: sum your largest concurrent loads (e.g. 1.5-ton AC = 1.8 kW + lights/fans 0.5 kW + fridge 0.4 kW + geyser 1.5 kW = 4.2 kW).
- Add 20% safety margin: 4.2 × 1.2 = 5.0 kW.
- Pick the next standard inverter rating: 5 kW, 6 kW, 8 kW, 10 kW.
- Match the PV array kW to ~1.3× inverter rating to handle clipping and PV derating at high temperature.
- For 3-phase commercial: use 10 kW or 15 kW 3-phase hybrid inverter; for single-phase residential under 8 kW use single-phase.
Worked example: 5-bedroom Lahore home with 1× 1.5-ton AC + 1× 2.5-ton AC
Peak load: 1.8 + 3.0 (ACs running together) + 0.5 (lights/fans) + 0.4 (fridge) = 5.7 kW. Add 20%: 6.8 kW. Pick 8 kW inverter (Inverex Nitrox 8kW, PKR 295,000). PV array: 8 × 1.3 = 10.4 kW (~18 panels of 580W).
4. DC + AC protection per NEPRA 2026 requirements
The inverter sits between three high-energy sources: PV strings (DC), battery (DC), and grid (AC). Each requires its own protection.
DC string-side (PV array to inverter)
- DC breaker — CNC YCB8 PV per string
- DC fuse — CNC YCF8 PV
- DC SPD — CNC YCS6-DC-1000V
- DC isolator — CNC YIS-DC-32-2P-1000V
Battery side
- DC breaker / fuse sized for max battery discharge current (typically 100-200 A)
- DC isolator for maintenance
- DC SPD if battery cables run outdoors
AC side (inverter output to grid + house)
- AC breaker — CNC YCB7 sized at 1.25 × inverter output current
- RCBO Type B — required by NEPRA 2026 for solar prosumer feed (CNC YCB10 Type B 40A from PKR 11,500)
- AC SPD Type II — CNC YCS6-T2-1P or 3P
- AC isolator — manual disconnect for inspection
Total CNC protection budget for a typical 8 kW residential install: PKR 35,000-50,000 across all stages. NEPRA inspectors check for each of these during net-metering approval.
5. Inverex vs Knox vs Crown vs Solis — honest comparison
| Inverex (PK leader) | Knox | Crown | Solis | |
|---|---|---|---|---|
| 6kW hybrid price (PKR) | 235,000 | 225,000 | 215,000 | 245,000 |
| Warranty | 5 years | 5 years | 3 years | 5 years |
| Efficiency (peak) | 97.6% | 97.0% | 96.5% | 97.6% |
| BMS integration | Inverex INV battery (best) | Knox + universal CAN | Universal Modbus | Universal Modbus |
| Local service | Country-wide | Country-wide | Lahore + Karachi | Karachi + Lahore |
| Pakistani market share 2026 | ~40% | ~15% | ~10% | ~5% |
| Modbus to Home Assistant | Yes (Solax driver works) | Yes | Yes | Yes (best HA integration) |
6. Installation considerations
- Mount inverter on a vertical wall, indoors or in a covered outdoor enclosure. Avoid direct sun — 47°C ambient cuts efficiency 8-12%.
- Clearance 50 cm above, below, and on each side for airflow. Inverter heat is the #1 cause of premature capacitor failure in Pakistan.
- Wire AC output through CNC YCB7 AC breaker + YCB10 Type B RCBO + YCS6-T2 SPD to your existing DB box.
- Wire DC inputs from PV strings through CNC YCB8 DC breakers + YCF8 fuses + YCS6-DC SPD.
- Wire battery through dedicated DC breaker + isolator.
- Configure: set battery chemistry (LFP / Lithium-ion / Lead-acid), capacity, low-voltage cutoff, charge/discharge currents per battery spec sheet.
- Connect Modbus / CAN bus to battery BMS if integrated chemistry.
- Run grid-aware automations on your Home Assistant (see our HA guide).
7. FAQ
What's the cheapest hybrid solar inverter in Pakistan 2026?
Inverex Nitrox 3kW at PKR 125,000 for small-house single-AC systems. For typical 6 kW residential: Crown 6kW at PKR 215,000.
Inverex vs Knox vs Crown — which is best?
Inverex has the largest service network and battery ecosystem fit, Knox is comparable at slightly lower price, Crown is budget option with shorter warranty, Solis is premium with best Home Assistant integration.
Do I need a hybrid or on-grid inverter?
For Pakistan with frequent outages: hybrid. The battery backup during load-shedding pays back within 18 months from saved generator fuel. On-grid only makes sense in tier-1 cities with reliable supply (rare in 2026).
What size inverter for a 5 kW solar system?
5 kW inverter rated for 5 kW PV. If you might expand the PV array later, pick 6 kW inverter and oversize battery accordingly.
Will my CNC DC breakers work with an Inverex/Knox/Solis inverter?
Yes — CNC DC breakers are inverter-agnostic. They sit between PV string and inverter input, working with any modern hybrid inverter via its MPPT inputs.
