Tripp Lite's RV750ULHW Inverter/Charger is the quiet alternative to gas generators—with no fumes, fuel or noise to deal with! It provides equipment with utility- or generator-supplied AC electricity filtered through premium ISOBAR surge protection. This DC-to-AC inverter with automatic line-to-battery transfer and integrated charging system serves as an extended run UPS, a standalone power source or an automotive inverter suitable for rugged RV applications. Supplies up to 750 watts of continuous 120V AC power from any 12V DC battery or automotive DC source. OverPower inverter output feature temporarily provides up to 150% of the continuous output for 1-60 minutes and DoubleBoost TM inverter output feature delivers up to 200% of the continuous output for up to 10 seconds, providing the extra power needed to cold start heavy-duty tools and motorized equipment. When hardwire AC input is energized, commercial power passes through to connected equipment and the battery set is recharged via 3 stage, selectable 11/45 amp charging system. In UPS mode, the APS system responds to blackouts and voltage fluctuations with a near instantaneous automatic transfer to battery-derived AC output. Includes a set of high current DC input terminals for simple installation(user supplies batteries and cabling - see owner's manual for recommendations). Passes sine wave utility or generator power during battery charging and UPS line power operation, plus efficient PWM sine wave AC output in inverter and UPS backup modes. Reliable large transformer design, with frequency control powers resistive electronic loads or large inductive motors, compressors and other items with high current needs on startup. Optional APSRM4 wired remote power switch with full status LEDs provides remote power inverter on/off switching and continuous status information(APSRM4 sold separately). Supports an unlimited amount of runtime with any number of user-supplied batteries connected. Highly adaptable to a variety of applications and site conditions with adjustable charger settings for wet/gel battery types and selectable line to battery power transfer voltages.

NOTE: To protect against high current draw that may occur during inverter failure, a fuse link rated at 125a should be positioned no more than 18" from the RV750ULHW's battery in the positive line.

Comments about Tripp Lite 750W PowerVerter RV Inverter/Charger with Hardwire Input/Output:

I purchased this unit and installed it myself. It was an easy installation. I removed the old non functioning ten year old unit and just copied the wiring from the old to the new. Each wire was colour coded so that made it easy and the unit indicated where each wire should go for the hard wired plugs.

I would not recommend this product.

Comments about Tripp Lite 750W PowerVerter RV Inverter/Charger with Hardwire Input/Output:

I've had my 2006 Class B and used the inverter 2 times and now have no output. The repair tech noticed that the unit was not clamped down, and, therefore must have bounced around for 3,000 plus mile.

What is the new model equivalent you referenced in your review?

Failed in less than 1 year

Comments about Tripp Lite 750W PowerVerter RV Inverter/Charger with Hardwire Input/Output:

Our new (2014) coach has been plagued with issues all related to our Tripp Lite inverter. Issues including damaged house battery, not charging from shore power in auto mode, and shuts off the generator (requiring cat5 cable be disconnected). Apparently there is a new version model back ordered (90 days) so we're done for the summer. I would not recommend this product to anyone. Upgrade to another brand at first chance.

Frequently Asked Questions

The RV750ULHW has an operating temperature range of -4° to +104° F (-20° to +40° C ).
 Yes, we offer Pure Sine Wave Inverters. Visit our Inverters product category and filter for Pure Sine Wave Output.  A pure sine wave inverter produces a smooth, sinusoidal AC output with a low level of distortion for better performance. A PWM (Pulse Width Modulated) Wave inverter produces a multi-step AC output that approximates a sinusoidal AC output with a higher level of distortion.

Additional FAQs may be available on the RV750ULHW model support page.
