The AIMS Power 12,000 Watt 48 Volt Pure Sine Inverter Charger is a low frequency powerhouse for backup and off-grid systems. Built on a 48 volt DC input for high efficiency in large systems, it delivers 12,000 watts of continuous split phase 120/240 volt AC power, with a 36,000 watt surge for up to 20 seconds. A 120 amp multi-stage charger, a 63 amp automatic transfer switch, and a direct-connect terminal block make it capable of supplying reliable electricity to an entire house, hunting cabin, off-grid vacation home, or business. It is ETL listed to UL 1741 and CSA standards and backed by a 3 year warranty.
The inverter outputs 100/110/120 volts and 220/230/240 volts AC, so it can run both standard 120 volt circuits and 240 volt appliances.
Low frequency construction delivers a 300% surge capability for up to 20 seconds through the direct-connect terminal block, helping large motors and compressors start.
The four-stage charger delivers up to 120 amps and charges gel, lead, AGM, and lithium LiFePO4 batteries, with eight battery charger settings and a current adjust dial from 0% to 20% to 100%.
The automatic transfer switch and bypass are rated at 63 amps at 220/230/240 volts, with a typical transfer time of 10 milliseconds.
A 48 volt input means lower current and less power loss than 12 or 24 volt systems at this scale. Selectable 25 watt power save mode reduces idle consumption from 200 watts to 40 watts.
Marine (conformal) coated boards protect against humidity and dust, dual thermally controlled fans and over temperature protection manage heat, and a dip switch selects 50 or 60 Hz output for international use. Battery priority mode and an optional remote panel (REMOTELF) add flexibility.
Home and business backup. AIMS Power notes the most common use is emergency backup power for residences and businesses.
Off-grid homes and cabins. Supply reliable electricity to an entire hunting cabin or off-grid vacation home.
Solar energy systems. Pair with a 48 volt battery bank charged by solar panels for renewable, off-grid living.
International installations. Selectable 50/60 Hz output and multiple voltage options support use in many regions.
Versus standby generators. A generator requires fuel and maintenance. This inverter charger runs silently from batteries and recharges from solar, the grid, or a generator.
Versus 12 or 24 volt inverters. At 12,000 watts, a 48 volt system greatly reduces current and cable size, improving efficiency.
Versus the 8000 watt model. AIMS Power offers an 8000 watt version in the same family for smaller loads.
