IOTA IIS 550 I NOBAT Stand-alone Emergency Inverter

The IOTA IIS 550 I NOBAT Stand-alone Emergency Inverter is a battery-free emergency power device designed to support essential loads during power outages. It accepts a 120–277 VAC input and ships without a battery (No Battery), meaning the unit is intended to operate as part of a larger backup configuration that stores or supplies energy separately. Identified by the IIS 550 I model line from IOTA, this stand-alone inverter provides emergency AC output in scenarios where a dedicated energy source is arranged outside the unit. The NOBAT designation confirms that no battery is included in the package. This configuration is suitable for installations that require a compact, ready-to-connect inverter for backup power without an integrated battery, with installation and wiring governed by applicable electrical codes and safety practices for emergency power equipment.
