Description

The Haisic 4.2 kW, 8 kWh All-In-One Solar Generator is a hybrid solar power system that combines a 4.2 kVA pure sine wave inverter, an 8 kWh lithium iron phosphate (LiFePO₄) battery, and a built-in MPPT charge controller in one compact unit. It is designed to provide reliable backup power for homes, offices, and small businesses, especially in areas with unstable grid supply.

Key Features

Inverter Output: 4.2 kVA (approximately 3.3–3.5 kW continuous load)
Battery Capacity: 8 kWh lithium iron phosphate battery
Solar Input Support: Up to 5 kW solar panel input (MPPT controlled)
Waveform: Pure sine wave (safe for sensitive electronics)
System Type: Hybrid (Solar + Battery + Grid compatible)

Appliance Capacity

With a 4.2 kVA system, the Haisic unit can comfortably power the following appliances (within load limits):

Lighting

• 15–25 LED bulbs

• Energy-saving lamps

Electronics

• 2–4 televisions

• 1–3 laptops

• Wi-Fi router

• Decoder

• Desktop computer

Kitchen Appliances

• 1 medium-sized refrigerator

• 1 freezer

• Microwave (used intermittently)

• Electric kettle (short-time usage recommended)

Cooling & Ventilation

• 3–6 standing or ceiling fans

• 1 unit 1HP inverter air conditioner (moderate usage)

Office Equipment

• Printers (non-industrial)

• CCTV systems

• POS machines

Actual runtime depends on total load connected. For example:

• A 1 kW total load can run for approximately 6–8 hours on battery.

• A 2 kW load may run for 3–4 hours without solar input.

When connected to solar panels during the day, runtime significantly increases as the battery recharges while powering loads.

Performance

• Seamless switching between solar, battery, and grid power

• Efficient MPPT charging for faster solar energy harvesting

• Long battery lifespan (typically 3,000+ charge cycles)

• Stable power output suitable for sensitive electronics

Build & Installation

The all-in-one design simplifies installation compared to separate inverter and battery setups. It reduces wiring complexity and saves space. The lithium battery technology ensures better safety, deeper discharge capability, and longer life compared to traditional lead-acid batteries.

Pros

• Reliable backup power for homes and offices

• Long-lasting lithium battery technology

• Supports heavy household appliances within limits

• Hybrid functionality (solar and grid compatible)

• Reduced generator fuel costs and noise
