Inverex Nitrox 20kW Hybrid Inverter 3 Phase LV IP65 (5Y)

The Inverex Nitrox 20kW Three Phase LV Hybrid Inverter is the largest low-voltage model in the Nitrox range, designed for large commercial premises including factories, warehouses, hospitals, large hotels and commercial complexes in Pakistan with peak loads of 15-19kW. Specific applications include medium textile mills, cold chain facilities, multi-floor shopping centres, large hospitals with ICU and operation theatre loads, and hotel properties with industrial kitchens and HVAC systems. With 350A battery charging current — the highest of any LV Nitrox model — and 30kWp solar input capacity, it can dramatically reduce electricity costs for high-consumption Pakistani commercial operations while providing reliable backup during load shedding.

The Inverex Nitrox 20kW LV and 30kW HV differ in three fundamental ways. First, battery voltage: the 20kW LV uses 48V low-voltage batteries (40-60V) while the 30kW HV uses high-voltage batteries (160-800V). HV battery systems are more efficient at higher power levels due to lower current for the same power. Second, output: the 30kW HV delivers 30000W versus 20000W on the 20kW LV — 50% more power. Third, solar input: the 30kW HV supports 48kWp versus 30kWp on the 20kW LV — 60% more solar capacity. Price difference is significant: the 30kW HV at Rs 3,550,000 is 3.7x more expensive than the 20kW LV at Rs 970,000, partly due to HV battery cost. For loads between 15kW and 19kW, the 20kW LV is the practical and cost-effective choice.

Up to 10 units of the Inverex Nitrox 20kW Three Phase LV can be connected in parallel, scaling total output from 20kW to 200kW. This makes the Nitrox 20kW one of the most scalable commercial hybrid inverters available from a Pakistani brand. A 5-unit parallel system (100kW) with 160kWh of lithium battery storage can power a large Pakistani factory or industrial facility through 8 hours of complete WAPDA outage without production interruption. The modular parallel approach also allows phased investment — a business can start with 2 units (40kW) and add more as energy consumption grows, rather than making a single large capital commitment upfront.

Yes, the Inverex Nitrox 20kW Three Phase supports energy storage from a diesel generator, which is critical for large commercial operations in Pakistan where grid power may be unavailable for 8-14 hours daily in some regions. The inverter intelligently manages three power sources simultaneously — solar panels, grid and diesel generator — automatically switching between them based on availability and programmed priority settings. During extended outages when batteries are depleted and solar generation is insufficient (cloudy days, night time), the generator charges batteries and powers loads directly. This three-source management reduces generator runtime by 40-60% compared to running a generator without a hybrid inverter, significantly reducing fuel costs and maintenance requirements for commercial operators.

For a large Pakistani business consuming 25000 kWh per month at commercial tariff of Rs 55 per unit (2026 average), the monthly electricity bill is Rs 1,375,000. A properly sized Inverex Nitrox 20kW system with 30kWp of solar panels and 64kWh of battery storage generating 9000-10000 kWh per month reduces the monthly bill by Rs 495,000-550,000. Total system investment is approximately Rs 12-15 million. Simple payback period is 22-30 months. After payback, annual savings of Rs 5.9-6.6 million continue for the remaining 23+ years of panel life. For Pakistani businesses currently spending Rs 1-2 million monthly on electricity, the Nitrox 20kW solar system is the highest-priority capital investment available today.
