The AIMS Power 4000 Watt 12 Volt Pure Sine Inverter Charger is a low frequency, split phase power center designed for 12 volt battery systems that need both 120 and 240 volt AC output. This version accepts 240 volt AC input for charging and pass-through, includes a 115 amp multi-stage charger and a 40 amp automatic transfer switch, and delivers a 12,000 watt surge for up to 20 seconds. Paired with a deep-cycle battery bank, it supports off-grid homes, business backup, cabins, mobile offices, vehicles, boats, and RVs.
The inverter outputs 120/240 volts split phase at either 50 or 60 Hz, with auto frequency detection, so it can serve both domestic and international installations.
A 300% surge for up to 20 seconds via the AC direct connect terminal block helps start refrigerators, freezers, microwaves, and power tools.
The charger supports lithium LiFePO4, gel, AGM, and lead batteries with seven battery type settings, adjustable current from off to 20% to 100%, and overcharge protection at 15.7 volts. AIMS Power recommends checking your battery charging specifications.
When AC input fails, the transfer switch moves your loads to battery power with a typical 10 millisecond transfer, keeping your power supply constant.
Battery priority mode supports solar-first systems, selectable 25 watt power save mode drops idle consumption from 50 watts to 21 watts, and an optional remote panel is available. Marine-coated boards protect against dust and moisture.
Home and business backup. Keep 120 and 240 volt circuits running during outages, with automatic transfer.
Off-grid cabins. Power lights and appliances in remote locations.
Mobile offices and businesses. Run equipment from a 12 volt vehicle system.
Storm preparedness. AIMS Power notes a battery bank and inverter can run a sump pump or heater when storms knock out power.
Versus the 120 volt input model. AIMS Power also offers this inverter charger with 120 volt AC input. Choose this version when your charging and pass-through source is 240 volt AC.
Versus the 6000 watt model. For tools with higher startup surges like air compressors, AIMS Power suggests its 6000 watt low frequency inverter charger.
Versus modified sine inverters. Pure sine output can run laser printers, computers, TVs, CPAP machines, and other medical equipment.
