Inverex Nitrox 8kW Hybrid Inverter 3 Phase LV IP65 (5Y)

The Inverex Nitrox 8kW Three Phase and Single Phase both deliver 8000W output but differ fundamentally in how power is distributed. The three-phase model distributes power across three phases (L1, L2, L3), making it essential for premises with three-phase electrical connections — typically commercial buildings, offices, factories and large homes with three-phase WAPDA meters. The three-phase model also supports 100% unbalanced output on each phase, meaning it handles different loads on each phase independently without performance loss. The single-phase model is designed for standard residential connections. In Pakistan, most homes use single-phase connections (230V), while commercial premises, factories and buildings above a certain load threshold are connected on three-phase (400V). Choose the three-phase if your WAPDA meter is a three-phase connection.

Yes, the Inverex Nitrox 8kW Three Phase Hybrid Inverter is well suited for small factories, offices, schools, clinics and commercial shops in Pakistan with three-phase connections. For a small garment workshop or a 2000-3000 square foot office, the 8kW three-phase provides sufficient backup for computers, lighting, HVAC and moderate machinery loads. It supports AC coupling to retrofit existing on-grid solar systems without replacing panels, and up to 10 units can be paralleled to scale the system to 80kW as the business grows. The diesel generator support is particularly valuable for Pakistani commercial operations where extended power cuts require a generator as a third power source alongside solar and battery.

Up to 10 units of the Inverex Nitrox 8kW Three Phase can be connected in parallel for on-grid and off-grid operation, scaling total output from 8kW to 80kW. For a medium-sized commercial premises in Karachi or Lahore with a 40-50kW peak load, 5-6 units in parallel with adequate battery storage provides complete independence from WAPDA load shedding. This is significantly more cost-effective than installing a single large commercial inverter, as parallel configuration allows incremental expansion and provides redundancy — if one unit requires maintenance, the others continue operating. Multiple battery strings can also be paralleled to increase total storage capacity proportionally.

The Inverex Nitrox 8kW Three Phase is compatible with both Lead-Acid and Lithium-ion batteries in the 40-60V low voltage range. For commercial applications in Pakistan where reliability and low maintenance are critical, LiFePO4 lithium batteries are strongly recommended. Compatible options available at MartOnline include Sunwoda Atrix Max 16kWh, Luminey Atrix 5kWh rack batteries and Mesol Infiniti 16kWh. For an 8kW three-phase system running a commercial premises for 8 hours backup, a minimum of 16kWh of lithium storage is recommended. The Nitrox 8kW three-phase uses self-adaption to BMS for automatic lithium battery communication, ensuring safe charging and discharging within the battery specified limits.

The Inverex Nitrox 8kW Three Phase comes with a 5-year manufacturer warranty from APT Inverex Solar Energy. For commercial buyers in Pakistan, Inverex local service network is a critical advantage — warranty repairs and spare parts are handled domestically without international shipping delays. Commercial customers at MartOnline receive dedicated WhatsApp support on +92 324 3493060 for system sizing, installation referrals and post-installation technical support. For businesses operating critical loads, we also recommend discussing an extended service agreement with your local Inverex authorised installer at the time of purchase to ensure maximum uptime and priority support response.
