This model is perfect for an RV with high watt components to power. I use it to power a 9200 btu rooftop air conditioner and it starts without issue. There is a place you can plug in a cable that starts a generator as well. I’m fairly sure everything on it works, but not certain enough to sell it as such, because I am not accepting returns.
Anyone who works on this type of equipment, or knows of a competent local repair shop could get a really good deal on what should wind up as a solid piece of gear.
I ship as soon as you pay, thank you for looking.

Features
RV3012OEM serves as an automotive or stationary DC-to-AC inverter with automatic line-to-battery
transfer and integrated battery charger
l
Supports 120V AC output from a 120V AC line power source or 12V DC battery sourcel
16.6 millisecond automatic transfer between line and battery power supports UPS protection during

up to 10 seconds
l
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.)
l

fast, reliable battery recharging
l
Protected hardwire bolt-down input lugs safely accept heavy gauge input wiring from attached battery
bank

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
l
Set of six front panel LEDs display AC/DC operational modes, overload status, DC voltage level,
shutdown status and system fault status
l
Set of 4 configuration dipswitches support wet/gel battery charging profiles, adjustable 135/145V high

Specifications
Resettable 30A charger AC input breaker and resettable dual 20A branch-rated AC output breakers and
automatic 2 speed cooling fan protect the inverter from load and temperature related failures
l
Grounding lug properly connects the inverter/charger system to earth ground or vehicle grounding
system
l
Automatic overload and thermal shutoff safely turns off inverter as excessive loads or overheating
conditions develop
l
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
l
Load sensing control dial enables adjustable load threshold required to automatically turn the inverter
on and off in DC mode as load conditions change
l
Includes battery temperature sensor with 20-ft. (6.09 m) cable to prolong battery life by adjusting the
charge level based on battery temperature
l
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
