Overview

Tripp Lite RV1250ULHW 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 1250 watts of continuous 120V AC power from any 12V DC battery or automotive DC source. OverPower TM 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 14/55 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 200a should be positioned no more than 18" from the RV1250ULHW's battery in the positive line.

Solid backup

By Finch

from Undisclosed

Comments about Tripp Lite 1250W PowerVerter RV Inverter/Charger with Hardwire Input/Output:

Last time a big storm went through here and threatened to flood my basement, the sump pump ran constantly just keeping up. I decided I needed power backup for the sump pump. A generator would be a pain because it would have to be outside with extension cord to the sump - nothing I could leave unattended.
So, I put together a system of TrippLite RV1250ULHW inverter/charger, 2 TrippLite batteries (98-121's) in a TrippLite battery case (BP-260), and mounted it on a cart I built for the purpose. I provided a GFCI outlet and grounded the set-up via my copper pipes. I have a TrippLite remote panel (APSRM4) installed at the top of the stairs, so I don't even have to go into the basement to check on the unit.
I'm not sure how long it will run the sump pump, but it should handle a day or two, hopefully longer than most storm downpours. It may even have sufficient capacity to pull some lights or the freezer.
I'm not wishing for a big storm, but I'll rest a little easier if it comes.

Good Unit , Little noisy

By Techman

from Undisclosed

Comments about Tripp Lite 1250W PowerVerter RV Inverter/Charger with Hardwire Input/Output:

I purchased this unit to provide backup power for woodstove cooling fan . We live in a area where the power is not reliable , and with us both working days needed a backup power source that could run a 500watt load for a couple of hours unintended . Unit works well , will run for 8 hours @ 500watt load on two 24ser/Deep cycle batterys . Inverter is a little noisy , and on slow recharge still has a humm . Good unit though , Power Ok , for not being a true sinewave .
