Core Advantages (Why Buy This Kit)

Complete "Turnkey" Cost-Saving Solution: Includes every single component—from panels and racking to cables, grounding kits, and tool bags. No need to source parts separately, reducing procurement hassle and hidden costs.

Next-Gen N-Type TOPCon Efficiency: Features 36 x Jinko 590W N-Type panels with 22.84% efficiency. Compared to traditional P-type panels, it delivers 3–5% more daily yield due to better low-light performance and significantly lower annual degradation (only 1% in the first year).

True 3-Phase Heavy-Duty Power: The 18kW pure sine wave three-phase output effortlessly starts and runs large inductive loads like central AC units, industrial water pumps, elevators, and light machinery—something single-phase systems struggle with.

High DC Oversizing & Wide MPPT Range: The inverter supports up to 36kW of DC input (safely covering your 21.24kW array). With an MPPT range of 160–650V, it captures power earlier in the morning and later in the afternoon.

2. Key Features (Technical Highlights)

Dual MPPT with 4 Input Strings: Supports independent tracking for arrays facing different orientations (e.g., East & South), minimizing power loss caused by partial shading throughout the day.

48V 15kWh Safe LiFePO₄ Battery Bank: Equipped with a smart BMS, supporting 150A continuous charge/discharge. Rated for >6,000 cycles at 25°C with 80% DOD, ensuring over 15 years of service life. Comes with a 5-year warranty.

Versatile Hybrid Operating Modes: Supports self-consumption, peak load shaving, off-grid UPS backup (with <10ms switchover), and grid feed-in (subject to local regulations).

Comprehensive Safety Protections: Includes dedicated DC high-voltage MCCB breakers (MOREDAY), AC surge protection device (SPD), waterproof junction boxes, and a full grounding kit—ensuring system safety and compliance.

3. Ideal Applications (Who Is This For?)

Large Luxury Homes & Villas: Power whole-house central air conditioning, underfloor heating, and EV chargers simultaneously without overloading.

Small-to-Medium Commercial Sites: Ideal for auto repair shops, small processing factories, refrigerated cold storage units, and boutique hotels with three-phase power requirements.

Off-Grid Islands & Remote Areas: Works perfectly as an independent micro-grid power station, especially when paired with a diesel generator for areas with unstable or no grid access.

Modern Smart Agriculture: Reliably powers large-scale irrigation pumps, ventilation systems for poultry/livestock farms, and greenhouse climate controls.

4. 🔥 4 SEO-Friendly Buyer-Oriented FAQs

Q1: How much electricity does this 18kW system generate daily, and is it enough for my needs?

A: Based on an average of 4 peak sun hours, this 21.24kWp array generates approximately 85–100 kWh per day. This is enough to fully power a 300–500 sqm luxury villa (including AC and kitchen appliances) or cover the daily daytime production needs of a small workshop consuming around 80 kWh per shift.

Q2: What roof area do I need to install these 36 panels?

A: Each panel measures 2278x1134mm. With a 10-30° tilt angle, you will need approximately 100–120 square meters of usable flat or pitched roof space (including clearance for maintenance). Our included aluminum racking is adaptable for both flat concrete roofs and standing-seam metal roofs.

Q3: Will the system keep my home powered during a grid blackout?

A: Absolutely. The hybrid inverter features a built-in off-grid UPS mode. When a power outage is detected, it automatically switches to battery backup in less than 10 milliseconds. Your refrigerators, computers, and lights stay on seamlessly, provided your batteries have sufficient remaining charge.

Q4: How long will the 15kWh LiFePO₄ battery last, and are replacements expensive?

A: Using automotive-grade prismatic LiFePO₄ cells, this battery is rated for ≥6,000 charge/discharge cycles at 80% depth of discharge (DOD). With one full cycle per day, the theoretical lifespan exceeds 15 years—far outlasting traditional lead-acid batteries. The modular design means you only need to replace the battery cells later on, not the entire hybrid system, significantly lowering long-term maintenance costs.
