Protect Against Power Disruptions

The S4K4U combines 6kVA of power capacity, flexible output voltage, internal batteries and an integrated maintenance bypass switch to provide protection for maximum system uptime. Consisting of two 3kVA, 120V inverters, its dual inverter engineering permits flexible output voltages to meet mixed load voltage requirements. The S4K4U automatically senses the input voltage and configures the output inverters to match the input supply to provide simultaneous output voltages, enabling users to power a variety of loads with different voltages without an additional transformer. Other features include self-diagnostic capabilities, multiple and simultaneous communication ports and a wide input voltage range that minimizes battery operations for increased battery life.
