AIMS Power 4000 Watt 48 Volt Pure Sine Inverter Charger

The AIMS Power 4000 Watt 48 Volt Pure Sine Inverter Charger Brings Efficient Split Phase Backup to Homes and Shops With a 240 Volt Panel

The AIMS Power 4000 Watt 48 Volt Pure Sine Inverter Charger is a low frequency inverter charger with a built-in transfer switch and battery charger, designed as a solution for backup or off-grid power. It converts 48 volts DC into 120/240 volt split phase pure sine power, producing two legs of 110 volts, which makes it a good match for home and shop applications with a 220 volt panel in place. With 4000 watts continuous, a 12,000 watt surge for 20 seconds and 48 volt input for greater efficiency, it provides reliable power for RV, boat, camping, business and residential emergency backup applications.

AIMS Power 4000 Watt 48 Volt Pure Sine Inverter Charger Features

Split Phase 120/240 Volt Output

The inverter outputs 110/120 or 220/230/240 volts AC split phase. Its two 110 volt legs suit home and shop installations that already have a 220 volt panel.

12,000 Watt Surge for 20 Seconds

Low frequency construction gives this inverter 300% surge capability, delivering 12,000 watts for 20 seconds and 4000 watts continuously, with a terminal block for hardwired connections.

Works at 50 or 60 Hz

Output frequency is selectable using the SW4 dip switch on the DC side of the unit, and auto frequency is supported. AIMS Power notes this makes the inverter operable with nearly any electrical system worldwide.

Multi-Stage Smart Charger With Lithium Support

The four-stage smart charger charges lithium LiFePO4, gel, AGM and lead batteries, with 7 battery type settings and adjustable charge current from off to 20% to 100%. Overcharge protection shuts down at 62.8 volts. AIMS Power recommends checking battery charging specifications for all batteries.

Automatic Transfer Switch and Battery Priority

The automatic transfer switch is rated at 50 amps at 120 volts or 30 amps at 240 volts, with a typical transfer time of 10 milliseconds. A battery priority selector lets you draw on your battery bank first.

Built to Handle Heat, Humidity and Dust

Over-temperature protection and dual thermally controlled fans help the inverter withstand reasonable heat and temperature fluctuations. Marine-coated, or conformal-coated, boards protect against humidity and airborne dust and dirt.

Power Save Mode and Remote Panel

Optional 25 watt power save mode reduces idle consumption from 1.67 amps DC to under 0.83 amps DC. A remote panel is available for convenient control.

Real-World Applications

Home backup with a 220 volt panel. Feed both legs of a split phase panel during outages.

Shops and garages. Run 120 and 240 volt shop circuits from a 48 volt battery bank.

RVs, boats and camping. AIMS Power lists RV, boat and camping applications among its intended uses.

Off-grid solar systems. Pair with a 48 volt battery bank and solar array for efficient off-grid power.

How It Compares to Common Alternatives

Versus the 6000 watt 48 volt split phase model. The 6000 watt version adds output capacity at 74 pounds. This 4000 watt model weighs 64 pounds and suits smaller load profiles.

Versus 12 and 24 volt inverter chargers. The 48 volt input offers greater efficiency, which matters most in larger systems.

Versus high frequency inverters. Low frequency inverters are heavier, but they handle startup surge from motors and compressors far better.

Is This Inverter Charger the Right Fit

• System voltage. It requires a 48 volt battery bank, with a minimum start voltage of 44 volts DC.
• Charging source. The charger uses 240 volt AC input, so confirm your AC source.
• Charger rate. AIMS Power lists the charger rate as 40 amps in its specifications and 115 amps in its features list, so confirm the rating with us if charge rate is critical to your system.
• Pass-through limits. Transfer is rated at 50 amps at 120 volts or 30 amps at 240 volts.
• Weight and size. At 64 pounds and 27.88" x 8.74" x 7.10", plan for a solid mounting location.

This may be a good fit if

• You have a home or shop with a 220 volt panel
• You run or plan a 48 volt battery bank
• Your loads fit within 4000 watts continuous
• You want lithium-compatible charging and automatic transfer
