The AIMS Power 2400 Watt 12 Volt Low Frequency Pure Sine Power Inverter delivers 2400W of continuous 120VAC pure sine power with a true neutral from a 12V battery bank. Its low frequency transformer design gives it a 7200W surge for up to 20 seconds, and AIMS lists it as capable of running a 2.4HP electric motor. It is ETL listed to UL 458.
It is meant for mobile, off-grid and backup systems that run compressors, pumps and motors alongside appliances and sensitive electronics. Output comes through a hardwire terminal block for the inverter's full capacity or a GFCI duplex receptacle for plug-in loads. AIMS points to simple installation and flexible mounting, so it suits professional installers and first-time off-grid owners alike.
Up to 300% of rated power is available for 20 seconds, which gives compressors and other motor loads time to come up to speed. Lighter overloads last longer, with 110% to 125% allowed for 15 minutes and 125% to 150% for 1 minute. AIMS notes that surges make extra heat and lower efficiency.
A three-position AC terminal block (ground, L and N) accepts 8 to 20 AWG wire, with 10 to 8 AWG recommended, and is protected by a terminal output circuit breaker. A GFCI duplex receptacle on the side gives you two outlets with their own GFCI output circuit breaker.
DSP (Digital Signal Processing) control keeps output within ±10% RMS as battery voltage drops under heavy load. THD is typically under 3%, with a 10% maximum under full linear load. The inverter starts at 10.0Vdc and raises an alarm and fault at 16.0Vdc or higher.
DIP switches set the low battery alarm and trip pair to 10.5/10.0Vdc, 11.0/10.5Vdc, 11.5/11.0Vdc or 12.5/12.0Vdc. Once the battery recovers to 13.0Vdc, the inverter restarts on its own if the switch is still on.
A 3-step fan adjusts speed to heat sink temperature and load and stays under 60 dB at 1 meter. If the heat sink reaches 221°F (105°C), the inverter shuts down its output after 30 seconds. Conformal coated circuit boards resist water, rust, dust and corrosion.
AIMS lists two optional monitoring add-ons for this model, the REMOTELF wired LCD remote and the BT-AIMS-PRO Bluetooth dongle. The LCD remote connects to the LCD RMT port on up to 60 feet of cable and shows battery voltage, output voltage, frequency, load, battery capacity and fault codes.
Service trucks with air compressors. Start and run a compressor and power tools from the truck's 12V battery bank.
Off-grid workshops. Run circular saws, grinders and other shop tools from a battery bank wired to a small panel.
Pumps and motors. Handle pump and motor loads that pull hard for a moment at startup.
Off-grid homes and backup. Power appliances and electronics from a 12V battery system during outages or full time.
Use the hardwire terminal when you want to feed a sub-panel or built-in circuits and reach the inverter's full output capacity. The GFCI outlets are quicker for cord-connected tools. AIMS notes the hardwire output is not ground fault protected, so plan any required GFCI protection on those circuits.
This inverter's transformer-based design is built for high surge loads, and AIMS says it suits power equipment and inductive loads. That design weighs 52.4 lbs here. A high frequency inverter is usually lighter and may suit loads with little startup surge.
A modified sine inverter makes a stepped waveform that some motors, chargers and electronics don't run well on. This inverter makes a pure sine wave close to utility power, so compressors and sensitive electronics can share it.
AIMS's manual says not to run the output at 100% continuously. For loads that run longer than an hour, keep them at 50% or less, which is 1200W here, to prolong the inverter's life. If efficiency is a priority, AIMS suggests a larger inverter rather than leaning on surge.
AIMS rates the DC input at 12Vdc and 240Adc. 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, and torque the DC terminals within 12.5 to 20.5 Nm, with 17 Nm (12.6 lb-ft) suggested, since over-torquing can break the bolt.
Mount it flat with the top side up, or on a wall with the DC terminals facing left or facing down. Never mount it upside down. AIMS calls for four 1/4-20 steel bolts with flat and lock washers and nuts, on a surface that can hold at least twice the inverter's weight.
AIMS recommends 12 inches of clearance around the inverter and at least 145 CFM of airflow, and says not to install it in a zero-clearance compartment. The case can reach 176°F (80°C), so keep it away from passersby.
If the LED is green with no buzzer and no AC output, the GFCI may be tripped, so reset it. If the output circuit breaker has tripped, reset the breaker.
No. AIMS says the LCD remote cable can be up to 60 feet long and shouldn't be extended. Never cut the cable while it's attached to a connected inverter, since a short can damage the remote circuit board inside.
The AIMS Power 2400 Watt 12 Volt Low Frequency Pure Sine Power Inverter brings a 7200W surge, hardwire and GFCI outputs and adjustable low battery protection to your 12V system. If you'd like a hand sizing cables, fuses or your battery bank, the Outbound Power team is happy to help.
