• 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 compatible with a one cycle transfer time
• 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
• 3 stage, selectable 14 / 55 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 settings
• Resettable 12A charger AC input breaker and resettable 20A AC output 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
• Load sensing control dial enables adjustable load threshold required to automatically turn the inverter on and off in DC mode as load conditions change
• Includes battery temperature sensor with 20-foot cable to prolong battery life by adjusting the charge level based on battery temperature
• Automatic generator starter jack enables user configuration of automatic generator startup as inverter batteries drop to 11.5VDC and generator shutoff as inverter batteries are recharged to 14.1VDC

Tripp Lite RV1250ULHW 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. OverPower inverter output feature temporarily provides up to 150% of the continuous output for 1-60 minutes, and DoubleBoost 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 14 / 55 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. It includes a set of high current DC input terminals for simple installation. 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. It supports an unlimited amount of runtime with any number of user-supplied batteries connected. It 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.
