The AIMS Power 4000 Watt 24 Volt Pure Sine Inverter Charger With Split Phase 120/240VAC Output is a low frequency inverter charger that combines a split phase pure sine inverter, a 55 amp multi-stage battery charger and a 30 amp automatic transfer switch in one heavy-duty unit. It is listed to UL 458, 1741 and 1012 and CSA 22.2 No 107.1 and 107.2. AIMS Power built it for medium-sized industrial applications that depend on power being available even under heavy load, and it fits renewable solar, off-grid, business backup, mobile and emergency backup systems that use 100 to 240 volts AC. Because it delivers both 120 and 240 volt output, it can serve standard household circuits and 240 volt equipment from the same 24 volt battery bank.
The inverter produces pure sine wave power at 100, 110, 120, 220, 230 or 240 volts AC. Split phase output lets one unit feed both 120 volt circuits and 240 volt loads, which is a common requirement in homes, shops and cabins. In bypass mode, the output waveform matches the incoming AC source.
Low frequency construction gives this inverter 300% surge capability, delivering 12,000 watts for up to 20 seconds and 4000 watts continuously. That reserve helps start motors, pumps and compressors that draw a large burst of power at startup. A 30 amp output breaker protects the AC output.
Listing to UL 458, UL 1741, UL 1012 and CSA 22.2 No 107.1 and 107.2 makes this model a strong candidate for installations where inspectors or project specifications call for listed equipment.
The built-in charger accepts any 240 volt AC source, including a gas or diesel generator or shore power, and charges lithium LiFePO4, gel, AGM and lead batteries. Seven battery type settings and adjustable charge current from off to 15% to 100% let you match the charger to your bank. AIMS Power recommends checking battery charging specifications for all batteries.
AIMS Power notes this model allows startup and pass-through power with depleted batteries. That helps when AC power returns after an extended outage and your batteries are drawn down.
The automatic transfer switch moves loads between AC input and inverter power with a typical transfer time of 10 milliseconds. Battery priority mode lets you run directly from your battery backup system instead of a generator or other AC source, which is useful in solar systems where you want to use stored energy first.
The selectable power save mode pulses every 30 seconds, looking for a load of 25 watts or more before it turns on. Otherwise the inverter sleeps, cutting idle consumption from 52.5 watts to under 25 watts. Low voltage shutdown at 20 or 21 volts, depending on your selection, keeps the inverter from completely draining your batteries.
Marine coating protects the electronics, auto frequency detection supports 50 or 60 Hz operation, and an optional wired LED or LCD remote lets you operate the unit from a vehicle cab or another location in the home or campsite.
Home and cabin backup with 240 volt loads. Run 120 volt circuits along with 240 volt equipment from one inverter during outages.
Off-grid solar systems. Pair it with a 24 volt battery bank and solar charge controller, using battery priority to draw on stored solar energy first.
Business and industrial backup. Keep critical equipment running through outages with listed equipment and a 30 amp automatic transfer switch.
Mobile and emergency power. Use a generator or shore power to charge batteries and pass power through, with automatic changeover when AC power is lost.
Versus the single phase 120 volt UL version. AIMS Power also offers a 4000 watt 24 volt listed model with single phase 120 volt output, a 45 amp charger and a 50 amp transfer switch. This split phase version adds 240 volt output and a 55 amp charger, with a 30 amp transfer switch.
Versus high frequency inverters. Low frequency inverters are heavier, but they provide much stronger surge for inductive loads such as motors and compressors.
Versus separate components. Buying an inverter, charger and transfer switch separately means more wiring and more space. This unit combines all three.
This may be a good fit if
Yes. It provides split phase 120/240 volt AC output, with output voltage options from 100 to 240 volts.
The 55 amp charger accepts any 240 volt AC source, including a gas or diesel generator or shore power.
No. Low voltage shutdown at 20 or 21 volts, depending on your selection, protects your batteries from complete discharge.
AIMS Power notes it allows startup and pass-through power with depleted batteries.
