The APSX2012SW 2000W APS X Series 12V DC 230V AC Inverter/Charger is a reliable power source for a wide variety of power tools, computers, audio/video components and other sensitive electronics at mobile, emergency and remote sites. With no fumes, fuel or excess noise, it’s an excellent alternative to generator power.

The DC-to-AC pure sine-wave inverter delivers network-grade power to sensitive electronics. Its automatic line-to-battery transfer switch and integrated charging system allow the unit to work as a vehicle inverter, standalone AC power source or extended-run UPS. It delivers 2000W of continuous power or 4000W of peak power during equipment startup or cycling. An automatic overload detector, cooling fan and resettable AC circuit breakers protect the unit from damage.

Designed for easy installation in RVs, commercial and fleet vehicles and emergency vehicles, the APSX2012SW converts stored power from any 12V battery or automotive DC source to safe, stable, computer-grade AC power for unlimited runtime. When hardwired to an external 230V AC source, the unit keeps the user-supplied battery charged via a three-stage 6-60A selectable charging system while simultaneously delivering AC power to connected equipment.

When used as a UPS, the APSX2012SW responds to blackouts and brownouts with an automatic, instantaneous transfer to battery-derived AC output. LEDs on the unit indicate battery voltage, charger and inverter status.

UPC Code037332161345
Nominal Input Voltage(s) Supported230V AC
Maximum Input Amps / WattsDC INPUT: Full continuous load - 240A at 12VDC. AC INPUT: 17 amps at 230VAC with full inverter and charger load (8.7A max charger-only / combined input load to support charger and AC output is automatically controllable to 66%-33%-0% based on AC output loading using the charger limiting set points - see manual for setting instructions)
Recommended Electrical ServiceDC INPUT: Requires 12VDC input source capable of delivering 240A for the required duration (when used at full continuous capacity - DC requirements increase during OverPower and DoubleBoost operation).

Questions & Answers

The batteries used with the inverter should be the same voltage and amp hour rating. If you're purchasing 6 of the 98-121 (12volt, 75 amp hour) batteries you will definitely have matching batteries and shouldn't have any battery backup issues.
