Purpose-built power conversion

The Tripp Lite APS1250 is a 1250W power inverter and charger that converts 12V DC battery power into 120V AC electricity. It includes automatic line-to-battery transfer switching for uninterrupted operation. A 6-foot cord connects the unit to the DC source. The rugged polycarbonate housing resists moisture and impact.

Ideal for backup and mobile AC needs

This unit suits installers building UPS-style backup for critical loads or mobile systems needing 120V AC from a 12V bank. The integrated charger replenishes batteries at up to 6.3A when AC line power is present. Buyers who need higher continuous wattage or a different DC input voltage should look at other models.

1250W continuous / 2500W peak rating

The inverter delivers 1250W of continuous output power with a 2500W peak capacity for motor starts. At full load it draws 127A from the 12V DC source. This rating determines whether your battery bank and cabling can support the connected equipment.

Questions about this item

Will the 127 A draw at 12 V DC work with my existing deep-cycle battery bank?

The unit pulls up to 127 A from a 12 V battery at full 1250 W load; ensure your bank and cables are rated for that current.

How can I verify the auto-transfer switch is functioning after installation?

With utility power present, the inverter passes AC through; pull the AC plug and the 120 V output should stay live from the battery without interruption.

Does the 6-foot DC cable included reach my battery, or must I buy longer leads?

A 6-foot DC input cable is supplied; longer runs require properly sized cable you source separately.
