Inverex Nitrox 30kW Hybrid Inverter 3 Phase HV IP65 (5Y)

The Inverex Nitrox 30kW uses a high voltage battery system (160-800V) versus the 48V low-voltage system used in the 3kW-20kW Nitrox models. The physics advantage is fundamental: for the same power transfer, higher voltage means lower current, which means less energy lost as heat in cables and connections. At 30kW output, a 48V LV system would require 625A of current — requiring extremely thick, expensive cables and causing significant energy losses. The 30kW HV system operates at 160-800V, reducing current to 37-188A for the same power, cutting cable costs and energy losses significantly. This is why high voltage batteries are standard in large commercial and industrial solar installations globally. The efficiency gain at 30kW scale means the HV system pays for its higher battery cost within 12-18 months of operation through lower energy losses alone.

The Inverex Nitrox 30kW Three Phase HV Hybrid Inverter is designed for large factories, industrial facilities, commercial complexes, hospitals and large hotels in Pakistan with peak loads of 22-28kW. Specific applications include medium textile mills, pharmaceutical manufacturing facilities, large cold storage plants, multi-floor shopping centres, hospitals with full medical equipment loads and hotel properties with 100+ rooms. With 48kWp solar input across 3 MPPTs and support for up to 10 parallel units scaling to 300kW, the Nitrox 30kW HV can power the largest Pakistani commercial operations while generating significant savings on WAPDA electricity costs. For a factory currently paying Rs 2-3 million monthly in electricity bills, a properly sized Nitrox 30kW system can reduce costs by 50-70%.

The Inverex Nitrox 30kW Three Phase HV supports up to 48000W of solar panel input with 3 MPPT trackers in a 3/2+2+2 configuration. On a large commercial or industrial rooftop in Pakistan, you can install 96-120 panels of 400-500W each. With 500W panels, 96 panels gives 48000W — the maximum input. A 96-panel system on a Karachi industrial rooftop with 5.5 peak sun hours generates approximately 264kWh daily — enough to power a large factory through an entire working day on solar alone. Roof space requirement is approximately 1600-1800 square feet for 96 panels. For factories with large flat rooftops, the Nitrox 30kW is an ideal fit, as the roof area is typically the limiting factor rather than the inverter capacity.

Yes, the Inverex Nitrox 30kW Three Phase HV supports AC coupling, allowing it to be integrated with an existing on-grid solar installation without replacing existing solar panels. This is particularly valuable for Pakistani commercial premises that installed on-grid solar systems in 2019-2022 when feed-in tariffs were attractive, and now want to add battery backup as load shedding has worsened. AC coupling connects the Nitrox 30kW in parallel with the existing solar system at the AC level, managing battery charging from both the existing solar system and the grid. This retrofit approach avoids the cost of replacing existing panels and inverters, typically saving Rs 1-2 million in equipment costs versus a complete system replacement for a 30kW scale installation.

A complete Inverex Nitrox 30kW HV system for a Pakistani commercial premises typically includes: Inverter Rs 3,550,000, HV lithium battery bank (2 units GoodWe BAT-S 51kWh = 102kWh) approximately Rs 6,000,000, 48kWp solar panels (96 x 500W) approximately Rs 4,800,000, installation and mounting approximately Rs 800,000 — total investment Rs 15,150,000. For a factory consuming 30000 kWh monthly at Rs 55 per unit (Rs 1,650,000/month), this system generates 8600 kWh monthly from solar, saving Rs 473,000 monthly. Simple payback period is 32 months. After payback, annual savings of Rs 5.7 million continue for the remaining 22+ years of panel life, delivering strong lifetime savings on the total investment.
