Magnum vs Victron Hybrid Inverter?

I'm about to replace the Inverter/charge controller and add solar to a 2018 FC 25FBT. I'm choosing between a Victron and Magnum 3000w Hybrid inverter and related accessories. I've had a Magnum before but not a Victron. I'd be interested in the thoughts of the community.

The choice is between the Magnum:
MSH3012M 3000W, 12v 125A Inverter
ME-BMK Battery Monitor
ME-ARC50 Remote control
PT-100 MPPT Solar Charge Controller
Total $2,990 (from iMarine)

Or the Victron:
Multiplus 12/3000/120-50 Inverter Charger
BMV-702 Battery Monitor with dongle
Digital Multi Control 200/200A
MPPT 100/50 Charge Controller with dongle
MK3-USB Computer Interface
Total $2,233 (from Amazon)

Note the Victron system as spec'ed doesn't have the spiffy color Control panel GX for $516. That's cool to watch, not sure if I actually need it given the battery monitor.

I know the Magnum solar charge controller is overkill. It's the only one they make and it integrates with the single control panel. The Magnum is nice in that everything works through the easy-to-mount panel.

These will be powered with 200W of Lithium and around 400-600W of solar (depends on what fits)

Thoughts on which is best? Things I'm missing (besides the usual master switches, fuses, etc.)

I installed a system with most of the Victron components you are considering and 400 w of solar and 320AH Lithium battery, you can see my post here:

I am very happy with my system so far. I have not yet purchased a Digital Multi Control or Control panel GX, still trying to decide which way to go or if I need either. Some authorized Victron dealers offer more product support than others (like programming your inverter/charger or solar controller), so you might factor that into your decision on where to buy from if you need that kind of help. --Frank.

Magnum vs Victron Hybrid Inverter?

To me this is like trying to choose between Mercedes and BMW. Both good setups and strong performers. You canít go wrong with either.

I looked at both and went with the Victron setup almost identical to what you have, pulse 320 Amphr of Victron lithium. My long install post is linked below.

For me, I like the vertical integration of the equipment as well as the ability to connect with an app on a smartphone to monitor. In addition, the Victron equipment cost a little less and seemed to have a long history of success in high end yachts and such.

I bought through AMsolar.com, and their support was awesome, prices were about the same. Very responsive and helped me with wiring diagrams and install tips as I was installing. note the Victron is a 2400W Unit, so a little smaller than the magnum. I also think that the Victron solar chargers are better built and perform better than the magnum. If you go magnum inverter, I would go with the solar charger from Victron, and also I think the Victron battery monitor is a better system. Just my opinion.

Iíve been very happy with my system and performance. Itís been great, no issues.
Good luck!

Itís a relief to hear the Victrons are working so well. Besides the slightly higher wattage what is the case for Magnums?

Second, Iíve toyed with going to 24v instead of 12 to keep the wire sizes smaller and currents lower. I know Iíd need a 24 to 12 converter then and would need to be more careful with shade on the roof since it would be a series/parallel arrangement with the solar panels. Any thoughts on that?

Howdy!

I would stay with the Victron components and use their 12VDC system. I use this on ALL of my installations and there is no reason to go to 24VDC other than the smaller wire. They work very well and offer a far greater range of products than Magnum does.

I still use the Magnum inverters and ME-RC control units sometimes, but you can't go wrong with either inverter!

Just my take on things!

Thanks Lew. That means a lot coming from you. It looks like Victron it is. I especially like their range of solar controllers that I can match more closely with my panel size.

What are your thoughts on the necessity of the Color GX panel?

Magnum vs Victron Hybrid Inverter?

I like the concept of a fully integrated system, with central monitoring. I plan to go with Victron lithiums, BMS, inverter/charger, MPPT solar charge controller, battery monitor, DC-DC converter, etc. etc.. when the install happens in the spring.

Lew is gonna hook me up at his shop in OR - right Lew?!

I am pretty sure Iím also going to install a CX panel, I like the idea of centralized monitoring of all system components, unless Victron release a newer version this spring... I remember hearing something about that somewhere...

For those looking to save $500ish you can install the Victron MPPT Control instead of the the Color GX. That little meter matches the battery monitor and letís you interact with the solar charge controller seeing things like live status and history. Between it and the battery monitor you can get a pretty clear idea of whatís going on. These things are only $78. They just run off the VE.CAN bus so are easier to install than the Color GX meter which needs multiple wires going here and there. Itís clearly not as sexy, though. It also doesnít connect to the inverter.

Another alternative is to get a couple of Victron bluetooth dongles for about $50 each and then you can monitor the mppt charger and battery monitor from your smart phone. I think Troutboy went this route. Unfortunately last I checked they did not work with the inverter/charger and I don't think they let you change settings. I'm still trying to decide whether to invest in the dongles, the mppt control and digital multi control for the inverter, or the color control GX. While expensive I guess an advantage of the color control GX is having one device that displays everything and even allows you to do some programming. Another alternative at half the price of the to the color control GX panel is the Victron blue control panel GX, but I don't know how its capabilities compare and I heard somewhere it was being phased out. --Frank

I do know that the newer solar controllers that Victron makes (100/30, 100/50 etc.) already have an INTERNAL blue tooth dongle which totally eliminates the need for an external one.

I also believe (have to check it out) that their BMV-712 ALSO has this internal device.

You can't go wrong with EITHER device in your rig!

I've been building / using alternative energy systems for over 35 yrs. and have not noticed the Victron brand yet , looks interesting , would need to do some more research before I would recommend .
Magnum on the other hand has been around a long time , with a very good reputation , so could only recommend Magnum because I know and have compared to maybe about half dozen other " quality " brands with a long history , in fact it is no my list for future RV inverter / charger RV upgrade , the only issues is I do electronic component level repair , so it is much cheaper to buy [ the last time I needed an inverter ] less than a dollar in parts to get a dead 2500 watt inverter / 100 amp charger http://www.xantrex.com/power-product...eedom-458.aspx
My main reason to up grade is to have pure sine wave .
So looking for a dead Magnum - so I can afford to upgrade
!!! If your going to use lithium battery !!! you should be using a BMS - battery management system , lithium batteries need to have a very specific control system , I have not seen any of the inverter / chargers set for lithium batteries ?
And in general I would not get any charge controller that was not programable for the battery bank being used .
An example of a good system design is how long the batteries last , my last battery bank 4 Trojan L16's running everything including AC , lasted over 12 yrs.

My controller and BMV have the separate dongle, older tech. I also installed the cheap MPPT controller

I like the MPPT controller as it allows me to turn of the inverter and also limit the amps.

If you check out my install, you can see how I installed it in place of the existing old stock inverter and remote.

Oh, and Lew is correct. You donít need the Bluetooth dongle if you buy the BMV712, or a new charge controller. They are internal now.

Sucks thatís my system is less than a year old and already I have old dated equipment, lol.

Thatís interesting. Thatís the reason I figured I need the digital Multi Control. Iíll probably put one in anyway since itís not that expensive and itís optimized for doing what find myself always doing but it is surprising you can do it from the MPPT controller.

If the Color GX control had the ability to turn on and off the inverter and set shore current limits Iíd probably just do that and be done with it. My understanding, though, is that it does not. On my previous Magnum unit I was doing that all the time.
