Be Energy Independent with a Hybrid Inverter

How Does a Hybrid Inverter Work in Off-Grid Mode?

A photovoltaic system's efficiency largely depends on selecting the right inverter. The hybrid solar inverter plays a crucial role by converting DC power from photovoltaic panels into AC power for household appliances. In off-grid mode, it connects the solar system, energy storage, and the grid, ensuring seamless power management.

Key Functions:

• Utilizes excess solar energy to power appliances and charge batteries.

• Stores surplus energy in LiFePO4, AGM, GEL, or other energy storage batteries.

• Automatically switches to off-grid mode when needed, supplying energy from stored reserves.

Why Choose a Hybrid Inverter?

Advanced Energy Management:

• Pure sine wave output for stable performance.

• Automatic restart during AC power restoration.

• Multifunctional touchscreen LCD for easy monitoring.

• 100A MPPT charge controller for maximum solar efficiency.

• Mains or generator power supply options.

• Configurable AC/Solar charging priority via LCD.

• Intelligent charger design for optimized battery performance.

• Adjustable input voltage for different appliances and PCs.

• Cold start function.

• Reserved communication port (RS485, RS232) for BMS support.

Maximize Solar Efficiency with MPPT Technology

The built-in 100A MPPT charge controller optimizes power extraction from solar panels, ensuring high performance even in low sunlight conditions. It also safeguards battery life by regulating charging processes.

Battery Management System (BMS)

The integrated BMS ensures optimal battery management by monitoring and adjusting charging and discharging parameters. This prevents overcharging and deep discharge, extending battery lifespan.

Multifunctional LCD Touchscreen Display

Stay informed with real-time monitoring of battery performance and system status. The intuitive LCD display allows users to:

• Adjust voltage ranges for home appliances and PCs.

• Set charging priority between AC and solar.

• Detect and respond to system faults with automatic safety shutdown.
