AIMS 4,000 Wt Pure Sine Inverter Charger (48V DC → 120/240V AC Split-Phase) — Industrial Backup & Off-Grid Power

Aims Power 4000WT Pure Sine Inverter Charger 12 VDC TO 120/240VAC PICOGLF40W12V240VS

Product Description

Combine this solar inverter charger with a deep-cycle battery bank for off-grid, mobile and emergency backup power.

The most popular feature of this unit is the direct connect terminal block, which allows a 300 percent surge capacity for up to 20 seconds. When using the terminal block, this inverter peaks at 12000 watts with the power to run many tools and appliances with a startup surges, such as a refrigerators, freezers, microwaves and blow dryers.

If you’re looking for an inverter with similar capabilities but a lower wattage capacity, check out the 2000 watt low frequency AIMS Power inverter charger.

Use this product for renewable solar, off-grid home and business back up power, mobile and emergency backup power applications anywhere that uses 110/120 OR 220/230/240 volts of alternating current. The inverter accepts 12 volts DC, which makes it great for vehicle upfitting as well as boat and RV applications that use a 12 volt battery system.  The inverter outputs 120/240 volts AC.

The marine-coated or conformal-coated boards also make this inverter great for mobile applications, as it protects the product from dust or water vapor that may be present in the air.

A low frequency label has been given to this inverter because of the lowered level of total harmonic distortion (THD) produced during the DC to AC inversion process. This allows for a cleaner transfer of energy, which increases efficiency, and it also provides a quieter performance.

This inverter will also run powerful tools like most electric chainsaws, portable grinders, shop vacs, and more.

Tools with higher startup surges like air compressors may require an upgrade to the 6000 watt low frequency AIMS Power inverter charger.

This 4000 watt inverter charger produces a pure sine wave, which some appliances require for use. So it can run laser jet printers, computers, televisions, CPAP machines and other medical equipment.

During a big storm that knocks out electricity, a battery-bank and power inverter running a sump pump could be the difference that saves a home from flooding. The power to run a heater could save someone thousands of dollars by keeping plumbing pipes from freezing.

Also great for emergency backup power applications is the automatic transfer switch on this unit, which keeps the power supply uninterrupted in the event of an outage. With the inverter hooked up to shore power, it will detect the loss of electricity and start pulling energy from a connected battery bank instead to keep the power supply constant.
