Features

Inverter
  • MRV2012UL serves as an automotive or stationary DC-to-AC inverter with automatic line-to-battery transfer and integrated battery charger
  • Supplies a 120V AC output from a 120V AC line power source or 12V DC battery source
  • 2000 watts continuous AC output in inverter mode, 3600 watts continuous AC output in AC line power mode

Automatic Transfer
  • 16.6 millisecond automatic transfer between line and battery power supports UPS protection during blackouts and voltage fluctuations for equipment compatible with a one cycle transfer time

Battery Charger
  • 3-stage battery charger with user-selectable 25/100 amp operation and adjustable settings for wet/gel battery types with charger on/off capability; offers fast, reliable battery recharging
  • Protected hardwire DC terminal posts safely accept heavy-gauge input wiring from attached battery bank
  • Protected hardwire output passes 120V line power or inverter output through to connected equipment
  • Extremely reliable large-transformer design tested to UL (USA & Canada) standards

Overload / Overtemperature Protection
  • DoubleBoost inverter output supports momentary startup loads up to 200% of the continuous rating for up to 10 seconds
  • OverPower inverter output supports longer duration overloads to 150% for up to 60 minutes under ideal battery and temperature conditions. (For best results, utilize OverPower usage as short of a duration as possible, ensure battery bank and cabling is able to provide full nominal DC voltage under load and allow inverter/charger to fully cool before and after OverPower usage.)
  • Resettable 25A charger AC input breaker and variable-speed cooling fan protect the inverter from load- and temperature-related failures
  • Grounding lug properly connects the inverter/charger system to earth ground or vehicle grounding system
  • Automatic overload and thermal shutoff safely turns off inverter as excessive loads or overheating conditions develop

Operating Modes / Display LEDs
  • 3-position operating mode switch supports "AUTO" mode to enable automatic transfer between DC and AC modes, CHARGE-ONLY to maintain a full battery charge when AC is present without auto transfer and SYSTEM OFF settings
  • Six front panel LEDs display AC/DC operational modes, overload status, DC voltage level, shutdown status and system fault status
  • 4 configuration dip-switches support wet/gel battery charging profiles, charger enable/disable capability, selectable 75/85/95/105V AC low voltage auto transfer points during brownout conditions
  • 4 additional configuration dip-switches support 4 levels of charger limiting relative to output load size, a battery equalization program and battery charger low/high settings

Optional Features
  • Front panel connector enables remote off/on switching (requires optional APSRM4 remote control module, sold separately)
  • Load-sensing control dial enables adjustable load threshold required to automatically turn the inverter on and off in DC mode as load conditions change
  • Battery temperature sensor with 20-ft. (6.09 m) cable to prolong battery life by adjusting the charge level based on battery temperature
  • Ignition Switch Control Jack can be used to connect the Inverter to your vehicle's ignition switch in order to automatically
    control the Inverter.
  • Automatic Generator Starter jack enables user configuration of automatic generator startup as inverter batteries drop to 11.5V DC and generator shutoff as inverter batteries are recharged to 14.1V DC

Construction
  • Moisture-resistant construction enables vehicular operation in high-humidity environments

Package Includes

  • MRV2012UL Inverter/Charger
  • Instruction manual with warranty information
  • Battery Temperature Sensor cable
  • Conduit hanger
RoHS compliant

Questions & Answers

Yes, we offer Pure Sine Wave Inverters. Visit our Inverters product category and filter for Pure Sine Wave Output. A pure sine wave inverter produces a smooth, sinusoidal AC output with a low level of distortion for better performance. A PWM (Pulse Width Modulated) Wave inverter produces a multi-step AC output that approximates a sinusoidal AC output with a higher level of distortion.
