Eaton MRV2012UL 12 V to 120 V 2000 W Power Inverter/Charger
Overview :
The Eaton MRV2012UL is a heavy-duty DC-to-AC inverter/charger with automatic line-to-battery transfer, designed for extended-run UPS, standalone power, or vehicle-based power conversion. It is typically deployed by facilities, IT infrastructure engineers, and mobile system integrators in applications ranging from rugged recreational vehicles to off-grid systems and industrial backup setups. It solves the need for reliable AC power from significantly different DC sources while providing integrated charging from AC mains.
Electrically, the unit accepts 12 V DC input from a battery bank and supplies 120 V AC, 60 Hz output with up to 2000 W continuous power capability. In inverter mode it uses a PWM-based sine wave output; in UPS mode it automatically switches from line power to battery power in roughly 16.6 ms, supporting loads compatible with typical UPS transfer times. It also incorporates a 3-stage battery charger with selectable 25 A or 100 A settings, adjustable for wet or gel battery types, enabling rapid recharge of connected battery banks.
Mechanically rugged, the MRV2012UL is intended for semi-permanent installations as well as vehicular or mobile environments; it includes heavy-duty DC input terminal posts and is hardened for high-humidity conditions. Its hardwired AC output and input make it suitable for integration into customized power systems where receptacles aren't provided on the unit itself.
Integration with site power infrastructure includes built-in premium surge protection and adjustable transfer thresholds to manage brownout and over-voltage conditions. Visual status and configuration are provided via front-panel LEDs and DIP switches for charger/transfer settings; optional remote control modules are available to add remote inverter control.
A practical deployment is in off-grid or mobile installations × for example, powering workshop tools or IT equipment from a vehicle or battery bank, with automatic transition to batteries on mains failure. It is not suited for data center UPS roles requiring true sine wave output and automatic networked monitoring; in such cases, line-interactive or online UPS systems with network cards are appropriate.
