Inverter install question

My fifth wheel has 50 amp service and the converter went out. I would like to replace it with an Inverter/Charger, I was looking at a "Tripp Lite RV750ULHW Inverter/Charger" and was wondering if anyone has any experience with this. I only need the inverter for television and satellite so 750 watts is plenty. I was just wondering if this particular unit would work with my trailer.
  • The Tripp Lite RV750ULHW has a very poor charging algorithm. Once the voltage hits 14.4, it drops back to float instantly. No way to program around the lack of timing.
    I have a customer with the RV750ULHW in her RoadTrek and we shut off the converter function and installed a PD9145. Now her batteries serve her well.

  • I looked at the Tripp-Lite(TL) very hard before choosing my two PSW inverters. A while back, you could search 'microwave' on the TL site. Today, 'microwave' is not found.

    Today, only the Pure Sine Wave(PSW) model's descriptions include "The DC-to-AC pure sine-wave inverter delivers network-grade power to sensitive electronics.".

    Personally, I would seek out reviews from actual users on what sensitive electronics they actually use.

  • Tripp Lite should work very well for you.

    Transfer switch may not be rated 50 amps so you may not be able to direct wire in the main feed. Wired on the single branch circuit should be fine.
  • It is hard wired....

    That's a fine unit, plenty of charger if you only have one small battery.

    More details will get better answers.
  • Triplite products are practically bullet proof
    At least the PV1250 inverter I have , has been bullet proof
    6 yrs of full-time use ,
  • Remove the AC cable from your power center going to the TV/ SAT and attach it to the AC output of the Inverter / Charger. Run a new AC cable from the old breaker to AC input on the I/C. Run DC power cables from the I/C to your existing batteries.
    When you have generator or shore power the I/C sill charge the batteries in parallel with your current charger / converter, and pass power to the TV/SAT. When there is no AC power, the I/C will generate AC for the TV/SAT, pulling power off the batteries. Figure 1 amp hour of batteries consumed for every 10 watt hours used. There is also power wasted when the loads are off by the inverter's load sense. Add at least 1 battery to your current bank, and go for it. 100 watts or more of solar on the roof would be nice as well.
  • The 12 volt output and charging rate would be a little concern. If I read it right it is 11-45 amps.
    I think I would get a good quality converter replacement and then a stand alone inverter for your needs.
  • A tv with an external power supply can be made work by plugging it into the cigarette lighter. I had to get a lighter plug that upped the voltage, 16 iIRC, but it is easy to do and won't have the parasitic draw of an inverter.

    A better use for an inverter is the microwave. On my TT I installed a Tripp Lite 2,000 watt inverter/charger. I think it was an APS 2012. The only problem was that the microwave did not like the MSW power and did not work correctly. I would spring for a PSW model. I made mine whole house and fed the panel by use of a 2 way automatic switch for the inverter and the plug. I mounted it in the front storage compartment and ran AC th the rear underneath the panel, I used exterior wire. I had to drill 2 holes in the floor. One in the front to deliver heavy cable to the inverter charger, and one beside the panel for the AC. Be sure and fuse the DC cable before it goes into the inverter/charger.
