Tripp Lite's RV750ULHW Inverter/Charger is the quiet alternative to gas generators—with no fumes, fuel or noise
to deal with! It provides equipment with utility- or generator-supplied AC electricity filtered through premium
ISOBAR surge protection. This DC-to-AC inverter with automatic line-to-battery transfer and integrated charging
system serves as an extended run UPS, a standalone power source or an automotive inverter suitable for

rugged RV applications. Supplies up to 750 watts of continuous 120V AC power from any 12V DC battery or
automotive DC source. OverPower inverter output feature temporarily provides up to 150% of the continuous output for 1-60 minutes and DoubleBoost TM
inverter output feature delivers up to 200% of the continuous output for up to 10 seconds, providing the extra power needed to cold start heavy-duty tools and
motorized equipment. When hardwire AC input is energized, commercial power passes through to connected equipment and the battery set is recharged via 3
stage, selectable 11/45 amp charging system. In UPS mode, the APS system responds to blackouts and voltage fluctuations with a near instantaneous
automatic transfer to battery-derived AC output. Includes a set of high current DC input terminals for simple installation(user supplies batteries and cabling see owner's manual for recommendations). Passes sine wave utility or generator power during battery charging and UPS line power operation, plus efficient
PWM sine wave AC output in inverter and UPS backup modes. Reliable large transformer design, with frequency control powers resistive electronic loads or
large inductive motors, compressors and other items with high current needs on startup. Optional APSRM4 wired remote power switch with full status LEDs
provides remote power inverter on/off switching and continuous status information( APSRM4 sold separately). Supports an unlimited amount of runtime with
any number of user-supplied batteries connected. Highly adaptable to a variety of applications and site conditions with adjustable charger settings for wet/gel
battery types and selectable line to battery power transfer voltages.
NOTE: To protect against high current draw that may occur during inverter failure, a fuse link rated at 125a should be positioned no more than 18" from the
RV750ULHW's battery in the positive line.
RV750ULHW serves as an automotive or stationary DC-to-AC inverter with automatic line-to-battery transfer and integrated battery charger
Supports 120V AC output from a 120V AC line power source or 12V DC battery source
16.6 millisecond automatic transfer between line and battery power supports UPS protection during blackouts and voltage fluctuations for equipment

Double Boost™ 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 1-60 minutes under ideal battery and temperature conditions.(For best
results, utilize OverPower usage for 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.)
3 stage, selectable 11/45 amp battery charger with adjustable settings for wet/gel battery types offers fast, reliable battery recharging
Protected hardwire bolt-down input lugs safely accept heavy gauge input wiring from attached battery bank
Protected hardwire output passes 120V line power or inverter output through to connected equipment
Reliability enhanced large-transformer design tested to UL(USA) and CSA(Canada) standards
Moisture-resistant construction enables vehicular or marine operation in high humidity environments
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
Set of six front panel LEDs display AC/DC operational modes, overload status, DC voltage level, shutdown status and system fault status
Set of 4 configuration dipswitches support wet/gel battery charging profiles, adjustable 135/145V high voltage auto transfer during overvoltages and
selectable 75/85/95/105V AC low voltage auto transfer during brownouts
Set of 4 additional configuration dipswitches support 4 levels of charger limiting relative to output load size, a battery equalization program and battery
charger low/high/off settings
Resettable 10A charger AC input breaker and automatic 2 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
Front panel remote control connector enables remote off/on switching(requires APSRM4 switch accessory). Optional APSRM4 accessory also includes
user configurable jacks to support inverter shutoff or startup as a vehicle ignition is engaged
Load sensing control dial enables adjustable load threshold required to automatically turn the inverter on and off in DC mode as load conditions change
