Tripp Lite RV Inverter/Charger

The Tripp Lite RV1250ULHW converts 12 V DC battery power or 120 V AC shore power into 120 V AC output for recreational vehicles and stationary installations. It delivers 1250 W continuous and 2500 W peak through a pulse-width modulated sine waveform. An automatic line-to-battery transfer switches sources without interruption, while an integrated charger replenishes the connected battery when AC is present.

Suitable for RV and fixed-site backup.

This unit suits RV owners and installers who need hardwired AC distribution with automatic transfer and charging built in. It is not for users who want a portable inverter with standard outlets, nor for anyone requiring a pure sine waveform for sensitive medical or audio equipment. Buyers needing higher continuous wattage or a different DC input voltage should consider other models.

1250 W continuous and 2500 W peak capacity

The continuous 1250 W rating determines which combination of appliances can run together, while the 2500 W peak handles brief motor-start surges. Both figures are fixed by the hardware and cannot be exceeded. Verify your total load against these numbers before installation.

Questions about this item

How is the RV1250ULHW hardwired into an RV electrical system, and what step do installers often miss?

Connect the 12 V DC battery cables and the 120 V AC input/output wiring to the hardwired terminals; the step often missed is torquing every DC lug to the manual's spec so voltage drop stays low under 1250 W continuous load.

What maintenance will the integrated battery charger require over its 30-month warranty period?

Inspect the hardwired DC connections for corrosion every six months, verify the charger's absorption and float voltages match the battery bank, and clean the ventilation openings so the PWM sine-wave circuitry stays cool.

Which limit appears first when running the inverter at full 1250 W continuous output for extended periods?

Thermal protection engages once internal temperature exceeds the design threshold, causing the unit to shut down until it cools; adequate airflow around the 7 × 8.8 × 9 in chassis delays this limit.
