InfiniSolar V4 Pro TWIN (Single-Phase)
User-friendly LCD and Dual output
InfiniSolar V4 Pro TWIN is a high-performance smart solar inverter and energy storage system with a maximum PV input power of 9000W and a PV input current of up to 30A. It features dual outputs for intelligent load management and a 4.3-inch color touchscreen for easy operation. The system allows programmable power supply priority (PV, battery, or grid) and user-adjustable charging current and voltage. It supports multiple operating modes, including grid-tie, off-grid, and grid-tie with backup. Built-in Wi-Fi enables remote monitoring via mobile apps (Android/iOS), and a reserved communication port allows integration with a Battery Management System (BMS). The system also supports parallel operation of up to 9 units, making it suitable for flexible energy management applications.
