Supplier's note

1. Technical Breakthroughs:

   • The Pro Model’s 200% overload protection triples the industry standard, enabling safe operation under extreme loads.
   • The Pro’s high-resolution display (640x480) provides granular data visualization for precision control.
   • The Advanced Model’s CAN bus compatibility streamlines integration with smart systems.

2. Version Selection Guide:

   • Base Model: Ideal for small-scale operations (e.g., residential backup power) requiring basic monitoring and control.
   • Advanced Model: Suited for commercial users needing enhanced performance (e.g., construction sites) with faster response and higher resolution.
   • Pro Model: Designed for heavy industrial applications (e.g., mining, power plants) where durability, overload tolerance, and precision are critical.

With the Pro Model’s triple overload protection, you can safely handle peak demands in extreme environments. Pair its high-resolution display with CAN bus connectivity to create a fully automated, real-time monitoring system for large-scale operations.
