1. The Brain: 20kW 3-Phase Intelligent Hybrid Inverter

• Advanced Power Management for Seamless Transition Our industrial-grade hybrid inverter is the command center of your energy system. It doesn't just convert DC to AC; it intelligently manages power flow between solar, battery, and grid.
• Pure Sine Wave Output: Delivers clean, stable power equivalent to the grid, protecting sensitive home electronics and industrial machinery.
• Dual MPPT Technology: Maximizes energy harvest from your roof, even with complex shading or different panel orientations.
• <10ms UPS-Level Switching: Ensure zero downtime. Your computers, servers, and medical devices stay on during sudden grid failures.
• Parallel Ready: Need more power later? This 20kW unit can be paralleled to expand your capacity as your energy needs grow.

 2. The Heart: 20kWh+ Ultra-Safe LiFePO4 Battery Bank

• Storage That Lasts a Decade, Not Just a Season We exclusively use Grade-A Lithium Iron Phosphate (LiFePO4) cells, engineered for safety and extreme longevity.
• 8,000+ Deep Cycles: Designed for daily use over 15 years. This is a one-time investment in a lifetime of power.
• Smart BMS (Battery Management System): Real-time monitoring of voltage, temperature, and current to prevent overcharging and ensure 100% safety.
• Modular "Plug & Play" Design: Easily increase your storage capacity by stacking additional battery modules without reconfiguring the entire system.
• Eco-Friendly & Maintenance-Free: No acid leaks, no gas emissions, and zero maintenance required—perfect for indoor residential installation.      

3. The Muscle: 580W+ N-Type TopCon Solar Panels

• Higher Efficiency, Smaller Footprint Our N-Type monocrystalline panels represent the pinnacle of 2026 solar technology, offering better performance than traditional P-type panels.
• Anti-PID & Low Light Performance: Generates electricity even during early mornings, late evenings, or cloudy days in SE Asia’s monsoon seasons.
• Exceptional Heat Tolerance: Lower temperature coefficient means these panels stay efficient even in the scorching heat of Africa and the Middle East.
• Bifacial Power Gain: (Optional) Capture sunlight from both sides, increasing total energy yield by up to 25% depending on the mounting surface.

4. The Nervous System: Real-Time Smart Monitoring

• Control Your Power from Anywhere in the World Stay connected to your energy production via our integrated WiFi/GPRS modules and the dedicated mobile app.
• Live Data Tracking: Monitor real-time solar production, battery state of charge (SoC), and household consumption.
• Remote Troubleshooting: Our technical team can assist with remote diagnostics, reducing the need for on-site maintenance.
• Historical Analytics: View daily, monthly, and yearly energy trends to optimize your usage and maximize your ROI.

 5. Safety & Durability

• Built for the Elements
• IP65 Rated Protection: Dust-proof and water-resistant casing, ideal for humid Southeast Asian climates or dusty African environments.
• Certified Compliance: Fully compliant with UL1741, CE (EN62109), and TUV standards, ensuring smooth local inspections and insurance approvals in the USA and Europe.

Professional Protection for Global Transit

Whether shipping to the ports of Lagos, the warehouses of California, or the islands of Indonesia, our multi-layered packaging ensures your 20kW system arrives in pristine condition.

1. What's in the Box? (Comprehensive Packing List)

Our 20kW 3-Phase Hybrid Solar Solution is organized into four main high-protection packages:

• Package A (Solar Modules): 36 units of 580W+ All Black N-Type Solar Panels (Reinforced Vertical Pallet).
• Package B (The Core): 1 unit 20kW SRNE 3-Phase Hybrid Inverter (Double-walled Corrugated Box with EPE Foam).

• Package D (Accessories): PV Cables, MC4 Connectors, Mounting Brackets, and Combiner Box (Organized Accessory Kit).

2. Industry-Leading Packaging Standards

• Solar Panels (Anti-Compression): We use heavy-duty reinforced pallets with corner protectors and transparent stretch film to prevent micro-cracks during forklift handling.
• Inverter & Electronics (Anti-Static & Shockproof): Encased in custom-molded EPE (Expanded Polyethylene) foam to neutralize vibrations and static during long-distance sea freight.
• Lithium Batteries (Dangerous Goods Compliance): Shipped in IPPC-certified fumigation-free wooden boxes. These meet international safety standards for Class 9 Dangerous Goods, ensuring smooth customs clearance.

3. Regional Logistics Optimization

• Africa & SE Asia (Durability First): All packaging includes anti-moisture desiccants and UV-resistant shrink wrap to protect against high humidity and tropical salt-spray environments during port storage.

FAQ

Q: Is the 20kW solar system shipped in one container?

A: A complete 20kW system typically occupies about 5-6 cubic meters (CBM). For international orders, it is usually shipped via LCL (Less than Container Load) for individual homes or bundled into 20ft containers for bulk commercial orders.

Q: How do you prevent solar panel breakage during shipping to Africa or the USA?

A: We use vertical insertion packaging which prevents the weight of the panels from pressing on each other. Combined with plywood outer-casing for long-haul routes, our breakage rate is kept below 0.1%.

Q: Are the batteries shipped separately from the panels?

A: Due to international maritime regulations, lithium batteries are classified as Class 9 Dangerous Goods. While they may arrive in the same shipment, they are packed in specialized UN-certified wooden crates distinct from the solar panels to ensure safety and regulatory compliance.

Q: How long does shipping take to my location?

A: Express shipping takes 3-7 business days to most countries; sea freight takes 15-30 days (varies by port).

Q: Can I track my order after shipping?

A: Yes. After shipping, we'll send a tracking number to your email. You can track your order on our website or the shipping carrier's official site.
