The AIMS Power 4000 Watt 12 Volt Pure Sine Inverter Charger pairs a heavy-duty low frequency inverter with a high-current multi-stage charger and a 40 amp automatic transfer switch. Combined with a deep-cycle battery bank, it delivers off-grid, mobile, and emergency backup power anywhere 110 or 120 volt AC is used. Its 12 volt input suits vehicle upfitting, boats, and RVs, and its direct connect terminal block unlocks a 12,000 watt surge for up to 20 seconds to start refrigerators, freezers, microwaves, and power tools. When grid power fails, it automatically switches to your batteries to keep the power supply constant.
The direct connect terminal block is the most popular feature of this unit, according to AIMS Power. It allows a 300% surge for up to 20 seconds, giving appliances and tools with startup surges the power they need.
Connected to shore power, the inverter detects a loss of electricity and starts drawing from your battery bank with a typical transfer time of 10 milliseconds, keeping your power supply uninterrupted.
The multi-stage charger supports lithium LiFePO4, gel, AGM, and lead batteries with seven battery type settings and adjustable current from off to 20% to 100%. Overcharge protection shuts down at 15.7 volts. AIMS Power recommends checking the charging specifications for your batteries.
Pure sine output can run laser printers, computers, TVs, CPAP machines, and other medical equipment, while low frequency construction lowers distortion for cleaner, quieter performance.
Conformal-coated boards protect against dust and water vapor, auto frequency detection supports 50 or 60 Hz, selectable 25 watt power save mode reduces idle draw, and an optional remote port lets you control the unit from a distance.
Storm and outage backup. AIMS Power points out that a battery bank and inverter running a sump pump can help prevent flooding, and power for a heater can help keep pipes from freezing.
Off-grid cabins. Power lights and appliances in a remote cabin.
Mobile business and offices. Run equipment from a 12 volt vehicle system.
RVs, boats, and camping. Power camping equipment and onboard appliances.
Work tools. AIMS Power says it will run most electric chainsaws, portable grinders, and shop vacs.
Versus the 2000 watt model. AIMS Power offers a 2000 watt low frequency inverter charger for lighter loads.
Versus the 6000 watt model. For tools with higher startup surges like air compressors, AIMS Power suggests stepping up to its 6000 watt low frequency inverter charger.
Versus modified sine inverters. Pure sine output is required by some appliances and is better for medical equipment and electronics.
