RV1250ULHW 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
1250 watts continuous AC output in inverter mode, 2400 watts continuous AC output in AC mode
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 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
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
Includes battery temperature sensor with 20-ft. (6.09 m) 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
