TruePower Plus Modified Sine Wave and Pure Sine Wave Inverters

I bought this to upgrade our RV from 1000W to 2000W so we can make coffee without starting the generator. The control panel is simple and no nonsense. Works well so far.

I installed this in my truck camper so that I can work remotely from wherever and not have to rely on a generator. The built in auto transfer switch is a nice feature that saves the headache of installing a separate one (which are all rather large). I can sometimes run the A/C with this, but sometimes the startup current is too much for it so I may do a soft start for the unit. It has a GFCI plug on the front of the unit as well as a USB, which is probably nice if you have it mounted somewhere accessible. I do plan to run a USB extension out for phone charging. The thing runs quietly and has a handy little remote panel to turn it on/off if you have it mounted somewhere out of reach (I do). Only complaint is that the LED light on the remote is ridiculously bright.The inverter came well packaged however the remote somehow got crushed. I contacted Pro Mariner, sent them the amazon invoice showing the date purchased, and they sent a new remote for free under warranty.Amazon has a lot of cheap Chinese inverters for sale. This is not one of them. Look up inverters used for commercial purposes, boating, etc, sold by actual box stores that live or die by the quality of the products they sell. None of the cheap Chinese stuff is sold by actual brick and mortar stores because it's all junk. Buy quality stuff the first time around...it's no fun replacing failed and expensive parts.

Beware - this is the second one we have purchased.After warranty expires they offer no repairs or technical assistance. Has to be replaced with new.We will not purchase another one.

I have one of these in an RV and it died approximately 2 months after the warranty. The features and what not are pretty common, but this one is about 20+% more than comparable ones. I think this is more of how it is mounted in my case, but the converter line in and the AC line out are huge pains because the wire gates end up pointing upward with little visibility into the slot (and they are small anyway).But in my case I made the choice to get this one because it is a complete drop in replacement.

Bought this in July 2018. Over 3 years later it still powers the 42 inch flat screen TV so we can watch football on our 28ft pontoon boat. Never had any trouble with it, have hooked to two 12v Marine deep cycle batteries from Bass Pro (in parallel) and the remote push button to turn on/off is really nice. Had an electrician test it for GFI to be sure no one would get electrocuted while swimming around the boat. The first 2 cheap Chinese inverters failed the test, this one passed and I kept it. Working strong after 3 years of occasional use.

I had this unit for five years and it seem to work pretty good but recently the Passthrough mode failed, and when I called customer support, their only answer was buy a new one. You can see in the photo that 133 V is coming in but the unit does not acknowledge that it’s there and stays on 12 V inverter mode. When I do buy a new one, it’ll be Xantrex or Victron.

Old unit went out and the way it was wired in my RV I had to replace it in kind. It was a bit pricey.

Easy to install and works great! Transition from shore power or generator to inverter is undetectable.
