We just upgraded out two heart inverters with Magnum MS4024 Inverters, the remote is very user friendly with regard to changing settings and fit perfectly into the power panel inside. These are pure sine wave inverters that replicate grid power and the charger settings allow flexibility. We did the installation ourselves, a friend in Oregon is a dealer and our cost for both units c/w remotes was just under 4k.

If it ain’t broke, don’t fix it. Your inverters are 2500 watts so if you upgrade to the now common 3500 to 4000 watt inverters your loads can be greater and your existing wiring may be too small. The change to newer inverters of greater capacity should involve heavier gauge wires to eliminate the chance for an electrical fire so the price quoted is not likely to reflect what it will really cost to pull new wires. Any installation that does not include heavier wiring either needs the same capacity inverters or some form of circuit protection to avoid potential overloads to the existing wires.

Bonz,

Think about upgrading the remotes only and keep the inverters, unless you just want to go new. Those Hearts are old and an upgrade to new would give you piece of mind.

Sawbonz,

I don’t like not being in control of my power after having a Vantare with two 4000 watt inverters with two easy to use remotes.. I can’t believe you have to remove the remote to change the settings !!

So far that is the only thing I am not happy with in the Liberty, I could manage my power anyway that suited me which made it possible to run all A/Cs at once at certain times. I really miss that.

I would love to have remotes that could control the charging especially, but like Jon pointed out the wiring could be an issue.

You can also manage your charge load by turning one of the invertor charge circuits off and you then only have one invertor charging your house batteries. If you do this during the day while maybe running more air conditioning or other loads. Then in the evening when you dont have lights on, microwave running and whatever else on then turn that second invertor charger back on for the evening….I would update the remotes, or if you want the piece of mind you could change to newer model invertors and save some money…..

Thanks Jeff… I wondered about that… then remembered that Liberty said to never turn them off… Vantare also said the same thing but I would just turn the Vantare down on both inverters to 5amps then at bed time put them back up to the default 15amp charging rate if they weren’t in float mode already otherwise I’d leave them on 5 amps… it was so simple to change the draw and made a huge difference in managing the A/Cs in the summer.

Being new to Heart inverters I didn’t dare do that.

Again thanks so much… these tips help out so much !

If you’re not increasing the output/charging capacity of your inverters, upgrading wiring should not be an issue. I switched Heart’s out of mine for pure sine-wave and, more importantly to me, the very issue you’re having…my coach is stored on a 20 amp circuit with the fridge on and requires charge rate to be low. I don’t believe that an upgraded remote panel allowing charge setting changes from the front of the panel was available for my Heart’s at the time I replaced them, maybe it is now. I currently have twin Outback 3524’s controlled by one remote panel. Another nice thing about the Outbacks is they are serviceable in the field.

And your old Heart’s are probably worth something. Post them here or on ebay.

Thank you, brain trust!

I just learned that it does consolidate the remotes into one, which is a big plus, and the lack of pure sine wave power now may be the cause of some erratic SubZero fridge issues. I don’t like load management at all, but if I have to do it I want to make it easy enough to do it correctly.

Field serviceable….also nice! I never would have thought of that.

Oh, and Liberty is doing the install. I don’t think that Frank would ever put it in if the wiring couldn’t handle it.

Liberty may even give you some credit for the Hearts.

The problem with the Sub Zero has nothing to do with your inverters. Sub Zero has a problem and they know it. My third condenser fan plus the labor to install it was free because this problem has nothing to do with the coach. Sub Zero is eating the cost, and while I can easily install the fan motor nothing makes me happier than having a Sub Zero dealer tell them on the phone they have to pay for the repair because this is and has been an ongoing problem.

I do receommend carrying the motor as a spare because if it quits when you are on the road it can be a problem.

perhaps it’s only your model year. Mine in the bus has had one fan and one compressor go out in three years and I have two at home with no problems.

[William]

Nope, I am not the only PC member who has experienced the same issue with the Sub Zero.

I don’t have Sub Zero in the bus, but have a couple at home. The big one in the kitchen has been worked on about 5 times in 11 years. Evaporater replaced twice, one compressor, one logic board, one display board and I think one fan too.

I have a small refer in the home theater that has been ok, but the 632 in the kitchen has been a real problem. In Sub Zero’s defense, they have eventually paid for everything but $1000, it is still a hassle you should not have. We bought top of the line when we built our new house and have had more trouble with that stuff than the cheapo stuff I had before…go figure.
