The SMS 4.2kVA hybrid inverter is a 24V solar inverter that delivers 4200W of continuous pure sine wave power, ideal for running essential household appliances like refrigerators, TVs, and lights during grid outages. It features a built-in 120A MPPT solar charge controller with a wide voltage range (typically 60-450VDC) to efficiently harvest and maximize energy from solar panels, reducing reliance on the grid. This versatile hybrid model supports seamless switching between solar, battery, and grid power, with additional capabilities like grid charging and selectable output voltages (220/230/240Vac). It provides reliable backup power and clean energy integration for off-grid or hybrid solar systems.
