Description

The MUST 3 kW, 7.2 kWh Solar Generator is a compact hybrid solar power system that integrates a 3 kW pure sine wave inverter, a 7–7.2 kWh lithium iron phosphate (LiFePO₄) battery, and an MPPT charge controller into a single unit. It is designed for residential and small business use, offering reliable backup power and efficient solar energy utilisation.

Key Features

Inverter Output: 3 kW (3000 W continuous, up to ~6000 W surge)
Battery Capacity: ~7.2 kWh LiFePO₄ battery (280 Ah)
Battery Life: 4000+ charge cycles
Solar Input: Up to ~1.5–1.8 kW solar panel input via MPPT
System Type: Hybrid (Solar + Battery + Grid support)
Output Type: Pure sine wave (safe for electronics)

Appliance Capacity

With a 3 kW inverter, this system is best suited for moderate household loads:

Lighting

• 10–20 LED bulbs

• Energy-saving lamps

Electronics

• 1–3 televisions

• 1–2 laptops

• Wi-Fi router

• Decoder

Kitchen Appliances

• 1 refrigerator

• 1 small freezer

• Microwave (short usage)

• Blender

Cooling & Ventilation

• 2–4 fans

• 1 unit 1HP inverter air conditioner (careful load management required)

Office Use

• Desktop computer

• Printer (non-heavy duty)

• CCTV system

Typical usage examples:

• ~800 W load → 7–9 hours runtime

• ~1.5 kW load → 3–5 hours runtime

Solar panels connected during the day will extend usage time by recharging the battery while powering appliances.

Performance

• Stable and clean power output for sensitive devices

• Efficient MPPT charging improves solar energy harvest

• Seamless switching between solar, battery, and grid

• Long battery lifespan due to LiFePO₄ chemistry

Build & Design

The system features an all-in-one structure, reducing installation complexity and saving space. It includes multiple output ports (AC, DC, USB) and built-in protections such as overcharge, short circuit, and voltage regulation.

Pros

• Compact and space-saving design

• Long-lasting lithium battery (4000+ cycles)

• Suitable for essential household appliances

• Hybrid functionality for flexibility

• Lower fuel and generator dependency
