Your All-in-One Power Conversion Hub

This compact unit combines multiple critical functions into one efficient package, eliminating the need for separate components and simplifying your system.

  • High-Efficiency Solar Charger: Built-in MPPT (Maximum Power Point Tracking) technology maximizes energy harvest from your solar panels, charging batteries faster and more efficiently than conventional controllers.
  • Pure Sine Wave Inverter: Produces high-quality AC power identical to—or even better than—utility grid electricity. This ensures compatibility with sensitive electronics like laptops, TVs, and medical equipment without risk of damage.
  • Smart Battery Management: Features intelligent charging profiles for various battery types, including lithium and lead-acid, to extend battery life and performance. Some models support direct communication with lithium battery BMS.
  • Automatic Transfer Switch: Offers optional UPS functionality with a super-fast transfer time (as low as 10ms), providing uninterrupted power to critical loads during grid failures.

Key Features for a Robust Home Energy System

1. Versatile and User-Friendly Design

Built to adapt to your specific needs with clear monitoring and control.

  • Clear LCD Display: Provides real-time information on operating mode, load levels, input/output voltage, and battery status, putting you in full control of your energy.
  • Wide Compatibility: Works with a broad range of battery voltages (24V or 48V DC systems) and accepts AC input from generators or the grid for flexible charging options.
  • Multiple Configuration Ports: Equipped with expansion ports for adding optional Wi-Fi modules for remote monitoring, dry contact cards for generator start/stop, and more.
  • Lightweight & Compact: Its high-frequency design makes it lighter and more compact than traditional models, easing installation and saving space.

2. Reliable Performance You Can Count On

Engineered for durability and stable operation in various conditions.

  • Strong Overload Capacity: Handles surge power from appliances like refrigerators, water pumps, or power tools (up to 200% of rated power for milliseconds), ensuring they start without issue.
  • Broad Operating Range: Functions reliably in ambient temperatures from -10°C to 60°C and high humidity environments, making it suitable for garages, sheds, or other non-climate-controlled spaces.
  • Quiet Operation: Engineered for low-noise performance (≤50dB), allowing for peaceful installation near living areas.
