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
