Hey Keith!

The Victron MultiPlus Pure Sine Wave Inverter Charger # VN68ZR is comparable, but not exactly the same as, or a direct replacement for, the Magnum MM1212-G. I found on Magnum Energy's website that the MM1212-G is rated for 1,200 watts of continuous output while the # VN68ZR is rated for 1,000 watts.

Going with the # VN68ZR would cost you about 200 watts of power, which can be a lot when you're camping. I know from our previous conversations that the Magnum MM1212-G is in your 2019 Renegade Vienna and you were considering upgrading to the 2,000 watt inverter/charger, and I think that's the way to go for your setup. The Victron MultiPlus Pure Sine Wave Inverter Charger # VN69ZR will definitely be an upgrade from the MM1212-G with its 1,600 watts of continuous output.

I know in the past we were looking at both the # VN69ZR and # VN68ZR. What's brought you back to the smaller one? I'm happy to answer any questions and make sure it's the right one for you!

The dimension of the VN69ZR at 19-15/16" tall is too long to fit into the necessary location and allow for connections to the wiring. Is there another inverter/charger that is shorter? The VN68ZR at 16 in. will give just enough room to connect the wiring.

The spec sheet for the Magnum 1212-G shows 1200VA. The spec sheet for the VN68ZR also shows 1200VA. Both show AC output at 120V. Since watts=VA/AC V, which for both inverter/chargers is 1000 watts please explain how the VN68ZR is 200 watts less continuous output than the Magnum 1212-G

@Keith Thanks for getting back to me! I can definitely see where the confusion is coming from, especially since both manufacturers list their inverters at 1,200 VA. The important distinction here is that VA (volt-amps) and watts aren't necessarily the same thing. VA measures apparent power, while watts measure the actual power being used. The relationship between the two depends on something called power factor. At a power factor of 1.0, 1,200 VA would equal 1,200 watts, but at a power factor of 0.8, that same 1,200 VA would equal 960 watts. Also, dividing VA by voltage gives you amps, not watts, so 1,200 VA divided by 120V would give you 10 amps. For the Magnum MM1212-G, the manufacturer rates it for 1,200 watts of continuous output at 77°F. Victron, on the other hand, rates the MultiPlus # VN68ZR for 1,000 watts of continuous output at that same temperature, even though it's also rated for 1,200 VA. That's where the 200-watt difference comes from. We're using the continuous wattage ratings provided by each manufacturer rather than converting their VA ratings directly into watts. One other difference worth mentioning is that your Magnum uses a modified sine wave, while the Victron produces a pure sine wave, which is generally better suited for sensitive electronics. I also saw your comment about the available mounting space in your 2019 Renegade Vienna. Since the larger # VN69ZR won't fit, I definitely don't want to recommend something that's too big for your compartment. What appliances or equipment are you typically running off the inverter when you're not connected to shore power? If we can get an idea of how much power you're actually using, we can figure out whether the 1,000-watt Victron will be enough or if we need to find something closer to your Magnum's original capacity.
