The AIMS Power 3000 Watt 12 Volt Split Phase 120/240VAC Low Frequency Pure Sine Power Inverter Delivers Both 120V and 240V From One 12V Battery Bank
The AIMS Power 3000 Watt 12 Volt Split Phase 120/240VAC Low Frequency Pure Sine Power Inverter turns 12V battery power into 120/240VAC split phase pure sine power with a true neutral. It is rated 3000W continuous with a 9000W surge for up to 20 seconds, and it is ETL listed. Each hot leg gives 120Vac to neutral, and the two hot legs together give 240Vac.
AIMS built it for homes, shops and backup power, including off-grid homes, mobile work vehicles and construction sites that need 240V for motors and pumps alongside everyday 120V loads. Wiring runs through a four-position hardwire terminal block, and a GFCI duplex receptacle covers plug-in loads. It is an inverter only, with no AC input, charger or transfer switch.
AIMS Power 3000 Watt 12 Volt Split Phase 120/240VAC Low Frequency Pure Sine Power Inverter Features
True Split Phase Output
The AC terminal block is marked ground, HOT1, HOT2 and N. HOT1 to N and HOT2 to N each measure 120Vac, and HOT1 to HOT2 measures 240Vac. AIMS's installation diagram shows the inverter feeding a sub-panel that serves both 120VAC and 240VAC outlets.
9000W Surge for High Inrush Loads
AIMS rates the surge at 3x continuous power for up to 20 seconds, for equipment with high inrush current such as motors, compressors and refrigeration systems. AIMS lists the unit as capable of running a 3.0HP electric motor. Lighter overloads of 110% to 125% run for 15 minutes and 125% to 150% for 1 minute before shutdown.
Hardwire Terminal With Its Own Breaker
A HOT1~HOT2 output circuit breaker protects the hardwire terminal, and the GFCI receptacle has its own GFCI output circuit breaker. The terminal accepts 8 to 20 AWG wire, and AIMS recommends 10 to 8 AWG. AIMS describes the hardwire connection as the way to use the inverter's full output capacity.
DSP Control Keeps Voltage Steady
Digital Signal Processing holds output within ±10% RMS as battery voltage changes. THD is typically under 3% and at most 10% under full linear load, so sensitive electronics, tools and appliances all get clean power. Output frequency is 50 or 60Hz by DIP switch.
Power Saver and Low Battery Settings
In Power Saver Auto, idle draw falls below 2.5W until a resistive load over 50W appears. DIP switches set the low battery alarm and trip pair from 10.5/10.0Vdc up to 12.5/12.0Vdc, and the inverter restarts when the battery recovers to 13.0Vdc.
Coated Electronics and Smart Cooling
Conformal coated circuit boards resist water, rust, dust and corrosion, and a 3-step fan adjusts to temperature and load at under 60 dB at 1 meter. The unit isn't splash proof, so install it in a dry, ventilated spot.
Real-World Applications
Off-grid homes. Feed a split phase sub-panel so 240V pumps and 120V lights and outlets share one battery bank.
Shops. Run motors and pumps that require 240V, plus 120V tools on the same inverter.
Construction sites and work vehicles. Bring split phase power to equipment where there's no grid connection.
Backup power. Supply a dedicated set of 120V and 240V circuits from batteries, wired separately from utility power.
Practical Comparison
Split Phase Versus a 120V Single Phase Inverter
A single phase inverter gives you 120V only. This model gives you two 120V legs plus 240V between them, so one inverter can serve 240V motors and pumps along with standard 120V circuits.
Low Frequency Versus High Frequency Inverter
The PILF's transformer-based design is what lets it hold 300% surge for 20 seconds, which AIMS says suits power equipment and inductive loads. It also weighs 57.3 lbs. A high frequency inverter is usually lighter and can suit loads with little startup surge.
Hardwire Terminal Versus GFCI Outlets
The GFCI duplex receptacle gives you 120V plug-in power. For 240V loads and for the inverter's full output, wire them to the hardwire terminal.
Buyer Guidance
Plan the Load on Each Leg
AIMS rates the inverter at 3000W continuous as a whole and doesn't publish a separate rating for each 120V leg. If you plan to put most of your load on one leg, check with the Outbound Power team first. AIMS's manual also says to keep loads that run longer than an hour at 50% or less, which is 1500W, to prolong the inverter's life.
DC Cabling for a 300A Input
AIMS rates the DC input at 12Vdc and 300Adc. Its chart suggests at least 1/0 AWG cable with a 300A fuse for runs up to 5 feet and from 5 to 10 feet. Keep the battery within 10 feet, ground the chassis with 8 AWG or larger copper wire and have a qualified installer such as a licensed electrician do the wiring.
This May Be A Good Fit If
- You need 240V and 120V from a 12V battery bank
- You run 240V motors or pumps
- You'll wire it into a split phase sub-panel
- Your steady load stays near 1500W
Common Questions
How Do I Get 240V From the Terminal?
Connect 240V loads between HOT1 and HOT2. Connect 120V circuits between either hot leg and N, and connect the ground to the ground position. AIMS warns not to loosen or touch the rear set screws on the terminal block.
Is the Terminal Output Ground Fault Protected?
No. AIMS notes the AC terminal output is not ground fault protected, so plan any GFCI protection your circuits require and follow all applicable codes. The GFCI duplex receptacle has its own ground fault protection.
Can It Feed a Panel That's Also on the Grid?
No. AIMS says the AC output must never be connected to utility power or a generator, because power fed back into the inverter will damage it instantly and may create a fire hazard.
Which Remote Can I Use?
AIMS's manual says to use only the REMOTELF wired LCD remote in the LCD RMT port, on up to 60 feet of cable, and warns that other remotes will damage the inverter. AIMS also lists an optional BT-AIMS-PRO Bluetooth dongle.
