New inverter what brand

The old inverter in my camper does not work. I would like to buy a new one to replace it. Looking for a 2000 watt. What is a good brand to buy and where would be a good place to buy one. I do not need one with a charger built in. Thanks

Is there some reason for a 2000 watt one? In general it is hard to imagine what you would be running which would need such a large inverter. Microwave or Toaster are the only things which come to mind. You need a lot of battery to support that size.

Second question, do you want/need a sine wave inverter or would a "modified sine wave" one work for you? Sine wave inverters are much more expensive than MSW ones.

The camper has 4 50w solar panels on it, 2 6volt batteries in series. The inverter that was in there was a 2000watt trace. It was a MSW inverter. I would like to go back with sine wave but they are very expensive. My son has downs, we will have to try to make him happy to be camping. He likes tv and game players. Here is a diagram of how the inverter and charger was installed. The univolt was replaced with pd charger. I am having trouble figuring out all the electric and solar but learning more every day. I helped him install the solar panels and work on it but never used it or camped in it.

Go power makes a real good inverter and yes they do come in 2000W pure sine. It will be the last one you buy! I would only go with pure sine for many reasons. Better efficiency, reliability, and they power all types of electronics not just most. Plasma TV, cell phone chargers, and all high end electronics (without that annoying buzz) are just some examples. Do lots of homework, if i have learned anything its that you get what you pay for in inverters. here's a link Go Power! 2000 Watt 12 Volt Pure Sine Wave Inverter

Not to rain on anyone's parade, but in my rather extensive experience in the RV and marine inverter field, I have found that the Go Power and Xantrex units (all of which are MADE IN CHINA) fail at an increasingly rapid rate and when they do, they are throw aways as they are NOT FIELD REPAIRABLE!! Same goes for the WFCO units that Airstream uses in their trailers.

They made the sensible move to start including Magnum MMS-1012 pure sine wave inverter/chargers into the Interstate coaches after 2013 models, as they should across their entire line of RV models. You get fully adjustable 4 stage charging and pure sine wave 120VAC in a variety of wattages, from 600 up to 3000 from a 12 VDC battery bank.

Magnums are made in the USA and can easily be repaired (in the unlikely event of a failure), at many factory authorized shops around the country, of which I am also one.

Like the old saw goes: Ya pays yer money and ya makes yer choice!!!!

PS: Why do you need a 2000 watt inverter? Do you plan on running a microwave from your battery bank? Just simple things like TV, device charging and gaming can be easily done with a Morningstar 300 watt sine wave model, which is also made in the USA!

Ditto to Lew's comments. Magnum makes a solid proven product if you really need the power. Buy once and you won't be disappointed later.

Huh...

I stand corrected, I have never had any problems with the purchase I made, but I would probably take your experience over mine... Thanks for steering me right!

Magnum units are programmable so that as the owner upgrades their batteries to different types, it can have a change in the parameters easily done to be completely compatible with the new battery style. Where style currently (2015) could be wet cell lead acid, gsm or lithium ion.

It was less than a five minute job to re-program our Magnum MS-2812 from the Lifeline GSM parameters to the lithium ion battery parameters.

Are there any complete system options? Say the Magnum for inverter and charger, but also a smart converter that would cut out the batteries when connected to ac and then provide 12v for lights, etc. Why not save the batteries when not needed?

The Magnum powers our 12Vdc fuse panel using shore power when available. It will use battery power when necessary. When I turn on the converter, both the AC bus and 12Vdc bus are powered. Between our 800 watts of solar panels and shore power, the battery is always topped up.

When installing any Magnum inverter/charger, there is no need for the redundancy of a converter. And NO converter is as 'smart' or programmable as a Magnum.

Magnums work differently than a converter. Converters produce 12VDC to directly power the trailer's DC loads and charge the battery when on shore power. In fact, you don't even need a battery when on shore power as the converter produces 12 VDC directly into the fuse block.

When no shore power is available, he 12 VDC loads are powdered directly from the batteries.

An inverter/ charger system is wired and works in a different way. The fuse block is connected directly to the batteries and they provide the 12 VDC for all of the DC loads. When the charger section of the inverter sees the corresponding voltage drop in the batteries, it adds charge back into the batteries. A quality inverter/charger never let's the batteries deplete much below 10% before the recharge starts.

If no shore power is present, the DC loads are still powered the same way, but you have the added benefit of producing 120 VAC power by the inverter from the battery bank.

There really is no need for any type of converter in a closed loop system like this. If you look at the battery charge cycle charts on the Lifeline web site, the 'normal' number if charge cycles at regular 50% depth of discharge is 1000. If you reduce the depth of discharge to 10%, the estimated number of charge cycles jumps to 5000.

Big difference! The less you stress the batteries, the longer they will last. I have 2 clients in their 10th years with a large 8-D battery bank in huge Prevost coaches. They still show over 90% capacity.

I do not have a brand recommendation but suggest that you check Amazon for pricing after you decide the best brand and model for your needs. They may or may not have the one you want, but if they do, their pricing is almost better than any other retailer.

I bought a new inverter from them a couple of years ago and it fit nicely and continues to work perfectly. Good luck!

And be sure to call Amazon when it stops working and you need to have it serviced!!!

At this time, a morningstar or magnum is out of my price range. I think the refrigerator is bad. It wont work on 110volts. I have the pilot light lit to see if it will maybe work on gas. Got to have tires also. Thanks for all the helpful information.
