Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Off-Grid Power Generation: A complete solar system designed to convert sunlight into usable electricity via high-efficiency monocrystalline silicon solar panels, paired with SunwayTech inverters to deliver AC power for appliances.
  • Energy Storage & Management: Equipped with durable LiFePO4 lithium batteries, ensuring reliable energy storage and efficient power distribution through an MPPT controller for optimal performance.

Key features

  • 1. Advanced LiFePO4 Battery Technology

    • With Sunway’s LiFePO4 lithium battery, you can achieve 2x longer lifespan and 30% faster charging compared to traditional lead-acid batteries*. This corrosion-resistant, eco-friendly material ensures reliable energy storage and safer operation in harsh environments.

  • 2. MPPT Controller for Enhanced Efficiency

    • Equipped with a Maximum Power Point Tracking (MPPT) controller, you can extract up to 30% more energy from monocrystalline silicon solar panels than PWM-based systems*. This optimizes power conversion, maximizing output even under low-light conditions.

  • 3. Scalable 3.5kW to 10kW Power Flexibility

    • With adjustable load power settings (2,000W–10,000W), you can customize the system to meet diverse energy needs—from powering small households to supporting larger appliances*. The 3.5kW base configuration delivers sufficient energy for daily use while allowing future upgrades.

  • 4. Off-Grid Reliability for Continuous Home Use

    • Designed for off-grid scenarios, this system ensures uninterrupted power supply for homes, even during prolonged outages*. The combination of high-capacity lithium batteries and ground-mounted monocrystalline panels provides stable energy for lighting, appliances, and heating/cooling systems.

  • 5. Multi-National Compliance and Eco-Friendly Design

    • Certified with CE and EPR standards in Germany, France, and Spain, this system meets rigorous safety and environmental regulations*. The LiFePO4 battery and recyclable components reduce ecological impact compared to lead-acid alternatives.

Supplier's note

  1. Technical Breakthroughs:

    • LiFePO4 Batteries: Triple the lifespan of lead-acid alternatives, reducing long-term replacement costs.
    • MPPT Controllers: 15% higher energy capture than traditional PWM systems.
    • Off-Grid Scalability: Modular design allows easy expansion from 2kW to 10kW without full system replacement.

  2. Version Selection Guide:

    • Base Model: Ideal for small households (e.g., weekend cabins) needing 2-3kWh daily.
    • Advanced Model: Suitable for mid-sized homes or farms requiring 4-6kWh daily.
    • Pro Model: Best for commercial use (e.g., resorts, workshops) with high energy demands (8-12kWh).

The Pro version’s 15kWh LiFePO4 battery and 96% inverter efficiency enable uninterrupted power for heavy-duty equipment, even in extreme climates. Pair it with monocrystalline panels for maximum ROI in sunny regions.
