Detailed Product Description

The SPI H3P Series represents the pinnacle of three-phase off-grid power conversion technology, delivering industrial-grade performance for mission-critical applications. These 8KW to 12KW inverters are engineered to power commercial facilities, agricultural operations, and remote industrial sites where reliable three-phase power is essential.

Industrial Power Features:

  1. Balanced Three-Phase Output ⚡
    Delivering true 230/400V three-phase power, the H3P series can run heavy machinery, commercial HVAC systems, and manufacturing equipment with perfect voltage balance across all phases. The <3% THD ensures clean power for sensitive CNC equipment and medical devices.
  2. Military-Grade Charging System 🔋
    The industry-leading 260A charging current (with generator input) means you can recharge massive battery banks up to 40% faster than competing models - crucial for operations with limited generator fuel or runtime windows.
  3. Extreme Environment Ready ❄️🔥
    Operating from -25°C to +60°C with intelligent thermal management, these inverters perform reliably in freezing cold storage facilities, scorching industrial plants, or dusty agricultural environments.
  4. Smart Energy Management 🧠
    The exclusive time-slot function automatically optimizes energy usage based on your schedule, while the dual BMS activation ensures perfect communication with lithium battery systems for maximum performance and lifespan.

Ideal Applications:

  • Manufacturing facilities
  • Agricultural operations (pumping, cooling)
  • Remote mining/oilfield sites
  • Telecommunications hubs
  • Cold storage warehouses
  • Water treatment plants
  • Microgrid implementations
  • EV charging stations

FAQS

Q :

Can this system power an entire commercial facility?

A :

Absolutely! The 12KW model can power small commercial buildings, and multiple units can be paralleled for larger facilities. A typical setup might include 24KW of inverters (2×12KW) with 50-100kWh battery storage for overnight operation.

Q :

What solar array size is recommended?

A :

We recommend 1.5× inverter rating for optimal performance - so 18KW PV for a 12KW inverter. The dual MPPT trackers allow separate array orientations to maximize daily production. The 200-650V input range accommodates commercial string configurations.

Q :

How does three-phase off-grid compare to single-phase?

A :

Three-phase provides balanced power delivery, eliminates neutral wire overload issues, and can deliver 3× the power capacity. Our commercial users report 25% lower installation costs (no load balancing needed) and 40% fewer maintenance issues compared to single-phase solutions.
