This powerful bundle pairs the EG4 FlexBOSS21 Hybrid Inverter with the WallMount Indoor 14.3kWh Battery, delivering a complete and dependable energy solution. Engineered for seamless integration, the FlexBOSS21’s advanced MPPT control works in harmony with the WallMount Indoor Battery’s lithium iron phosphate cells, ensuring top-tier safety and performance. Its intelligent Battery Management System (BMS) continuously monitors real-time metrics like cell voltage, module temperature, and current, while utilizing passive balancing and advanced control methods to optimize efficiency. Ideal for low-voltage indoor energy storage, this bundle provides reliable power and greater energy independence.
