Must PH11-15KL3-EU 15KW On/Off-Grid Hybrid Solar Inverter

Must PH11-15KL3-EU 15KW Three-Phase On/Off-Grid Hybrid Solar Inverter | 48V, IP66, WiFi, 2 MPPT | For Home, Office, Factory & Business in Nigeria

Stop paying for fuel and unreliable power. Run your business on the sun.

The Must PH11-15KL3-EU 15KW Hybrid Solar Inverter is a three-phase on/off-grid inverter for Nigerian homes, offices, schools, clinics, farms, hotels and factories that need serious, dependable power. It combines solar, battery, grid and generator inputs in one system. When NEPA/DisCo supply drops, your lights, ACs and machines keep running. When the sun is out, you cut your diesel and petrol spend.

Its 100% unbalanced output keeps uneven loads across all three phases stable, which matters in real commercial settings. The high-current battery charge/discharge capability handles heavy start-up loads, and the IP66 enclosure shrugs off dust and moisture. Built-in WiFi lets you check your system from your phone, and CT-based anti-backflow protection keeps your setup safe and grid-compliant.

Start with one unit and expand later. Up to 16 units can run in parallel, so your inverter grows with your business.

Ideal for: large homes and duplexes, offices and banks, shops and malls, schools, hospitals and clinics, hotels, cold rooms, borehole pumping, agro-processing, telecom sites and light industrial workshops.

Key Features

• 15,000W three-phase power: runs ACs, freezers, pumps, workshop machinery and whole-building loads from one unit.

• 100% unbalanced load output: each phase can carry a different load without tripping or derating.

• High-current charge/discharge (up to 320A for the series): handles sudden surge loads and fast battery charging.

• Four energy inputs: solar, 48V low-voltage lithium battery, diesel generator and grid, so you are never without power.

• Dual MPPT trackers (200-650V, 800V max DC input): more flexibility in solar panel string design, with up to 97.6% efficiency.

• IP66 waterproof enclosure with battery transformer isolation: built for dust, humidity and rain, with added electrical safety.

• Built-in WiFi and CT connection: monitor energy use in real time and prevent back-feeding to the grid.

• Scalable: parallel up to 16 units on-grid or off-grid as your power demand grows.
