Detailed Product Description

The UNITED ENERGY SEI-H3P Series redefines commercial-scale solar storage with its robust three-phase architecture. Engineered for demanding applications from factories to agricultural operations, these 8KW-12KW inverters deliver unmatched performance in the most challenging environments.

Industrial-Grade Advantages:

  1. Heavy-Duty Power Delivery 🏗️
    With true three-phase 230V/400V output and 24,000VA peak capacity, effortlessly power industrial motors, HVAC systems, and manufacturing equipment. The <1% THD ensures clean power for sensitive CNC machines and medical imaging equipment.
  2. Lightning-Fast Charging ⚡
    The industry-leading 260A charging current (with generator input) means you can recharge massive battery banks in record time - perfect for operations with limited generator runtime windows or time-of-use arbitrage opportunities.
  3. Military-Grade Resilience 🛡️
    Featuring PKS protection degree and fan-cooled design, these inverters thrive in dusty workshops, humid greenhouses, or freezing cold storage facilities (-25°C to 60°C operating range).
  4. Smart Energy Orchestration 🧠
    Our proprietary dual calibration BMS communication ensures perfect synchronization with lithium battery systems, while the peak-valley scheduling automatically shifts loads to minimize demand charges - typically saving 25-40% on commercial electricity bills.

Ideal Applications:

  • Manufacturing facilities
  • Agricultural operations
  • Commercial buildings
  • Microgrid implementations
  • EV charging stations
  • Telecom towers
  • Cold storage warehouses

FAQS

Q :

Can this inverter handle heavy motor starts?

A :

Absolutely! With 24,000VA surge capacity (12KW model) and true three-phase output, the SEI-H3P series can handle motor starts up to 3HP without flinching. The pure sine wave output ensures smooth operation of induction motors. 🏭⚙️

Q :

What's the maximum solar array size I can connect?

A :

The 12KW model supports up to 18KW of PV input (9KW+9KW across two MPPT trackers) - this oversizing capability ensures maximum harvest during winter or cloudy conditions. The 200-650V operating range accommodates both residential and commercial string configurations.

Q :

How does this compare to single-phase inverters for commercial use?

A :

Three-phase power provides balanced loading, eliminates neutral wire issues, and delivers 3× the power capacity. Our commercial users typically see 15-20% lower installation costs (no need for load balancing devices) and 30% more uptime compared to single-phase solutions. 💼📈
