Component features and specifications outlined below.


Built with a 48 volt DC input, this inverter performs with very little power loss. Users receive a notable increase in efficiency in large systems when compared to using inverters that accept 12 or 24 volts. This can be an attractive feature for sustainability lovers looking to live as efficiently as possible.

The most common use for this inverter is emergency backup power for residences and business. You’ll always be prepared for the next power outage with access to 12,000 watts of continuous power and 36,000 watts of surge (for up to 20 seconds).

 One of the most sought-after features this inverter has is the direct-connect terminal block, which allows users to surpass the 12,000 watt capacity and harness its 300% surge power (up to 36,000 watts for 20 seconds as previously noted).

This inverter is also built to withstand reasonable heat and temperature fluctuations because of its over-temperature protection and dual thermally-controlled fans.  And it’s protected from humidity or airborne dust and dirt by virtue of its marine-coated (or “conformal-coated”) boards. This inverter provides the reliability needed in any business or residential emergency backup power applications.

This inverter is split-phase and will output 120 or 220/230/240Vac, and it can output 50 or 60Hz via the SW4 dipswitch on the DC side of the product. This means that this inverter works internationally and is operable with nearly any electrical system on the planet!

This  48 Volt 150 AMP lithium iron phosphate (LiFePO4) industrial deep cycle battery is packed with power. The battery delivers efficient power for battery systems requiring large amounts of power at 48 Volts. The AIMS Power 48V 150 amp has large amp capacity in one battery and eliminates the need for LITHIUM BATTERY 48V 150AMP LIFEPO4 INDUSTRIALmultiple batteries without losing amperage. Compared to other battery technologies, this battery delivers large amounts of power, at half the weight and provides up to 8 times more battery cycles and no memory problems. Loaded with automatic safety features, such as a Battery Management System (BMS), which maintains individual cell integrity, low and high voltage protections, reverse polarity and temperature management. The battery also uses automatic cell balancing, requires almost no maintenance and includes RS485 and CAN monitoring.
