Inverex Nitrox 12kW Hybrid Inverter 3 Phase LV IP65 (5Y)

Yes, the Inverex Nitrox 12kW Three Phase Hybrid Inverter is one of the most capable commercial inverters available from a Pakistani brand, suited for offices, schools, clinics, small hotels and commercial plazas in Pakistan with three-phase connections. With 240A battery charging current and a 4ms transfer time — significantly faster than most commercial UPS systems which switch in 10-20ms — it provides near-seamless backup switching during grid failures. For a 5000 square foot office in Karachi or Lahore with 4-5 split ACs, computers, lighting and server room loads totalling 8-10kW, the Nitrox 12kW provides comfortable headroom and reliable backup. The built-in AC breaker eliminates a separate installation component, simplifying the electrical setup.

The 4ms transfer time on the Inverex Nitrox 12kW means it switches from grid power to battery backup in just 4 milliseconds when the grid fails. To put this in context, the human eye blinks in 150-400ms — the Nitrox 12kW switches 37 times faster than a blink. This speed matters enormously for sensitive commercial equipment: computers and servers experience no data loss or restart, industrial machinery maintains operational continuity, and medical equipment in clinics continues without interruption. Standard commercial UPS systems typically switch in 10-20ms. The Nitrox 12kW 4ms transfer is on par with the GoodWe GW12K-ET-L (under 4ms), making it competitive with the best international commercial hybrid inverters available in Pakistan.

The Inverex Nitrox 12kW Three Phase supports up to 15600W of solar panel input with dual MPPT trackers in a 2/2+1 configuration. For a typical commercial rooftop in Pakistan, you can connect approximately 31-39 panels of 400-500W each. With 500W Tier-1 panels (the most cost-effective choice for commercial rooftops in Pakistan as of 2026), 31 panels gives 15500W — very close to the maximum input. On a commercial rooftop in Lahore with 5.5 peak sun hours, this system generates approximately 85kWh daily — enough to power a medium commercial building entirely on solar during daylight hours and charge a 16-32kWh battery bank for evening and night backup during load shedding.

Yes, the Inverex Nitrox 12kW Three Phase includes a zero export function and is compatible with NEPRA net metering requirements for commercial electricity consumers in Pakistan. Commercial net metering allows businesses to export surplus solar energy to the grid during low-consumption periods (weekends, holidays, off-hours) and receive credit against their electricity bills. For a commercial office consuming 3000-4000 kWh per month, a properly sized solar system with the Nitrox 12kW can reduce the monthly electricity bill by 60-80% through a combination of direct solar consumption and net metering credits. Always work with a NEPRA-certified solar company and apply for commercial net metering approval from your local DISCO before connecting.

The Inverex Nitrox 12kW Three Phase, GoodWe GW12K-ET-L and SAJ H3 12kW are the three main commercial three-phase LV hybrid inverters available in Pakistan. Transfer time: Nitrox 12kW at 4ms matches GoodWe GW12K-ET-L and beats SAJ H3 12kW at under 20ms. Battery charging: Nitrox 12kW at 240A matches SAJ H3 12kW and slightly exceeds GoodWe at 228A. Parallel units: Nitrox 12kW supports 10 units versus GoodWe 8 units. Price: Nitrox 12kW at Rs 750,000 is competitive with GoodWe GW12K at approximately Rs 750,000-850,000. The decisive factor for most Pakistani commercial buyers is after-sales support — Inverex domestic service network provides faster resolution than GoodWe or SAJ whose Pakistan warranty support depends on local distributor capacity.
