GlennWest Posted July 8, 2022 Report Share Posted July 8, 2022 Trying to decide on inverter/s. Magnum using multiple inverters allow a percentage settings to turn on slave units. Reading over the manual on MultiPlus 2 don't see this option. My plans are 1 or 2 230 volt unit with a 100 amp autotransformer. Magnum should be a good power usage with this. Does Victron do this? I like the Bluetooth and lower cost of the Victron. But 2 inverters all the way in use is a larger power draw.

GlennWest Posted July 9, 2022 Author Report Share Posted July 9, 2022 I posted this question to the Victron Community. Maybe they know.

GlennWest Posted July 9, 2022 Author Report Share Posted July 9, 2022 Well. The answer was no. It cannot be programmed this way. So there are advantages to Magnum Quote 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1 Link to comment Share on other sites More sharing options...
franco-bolli Posted July 10, 2022 Report Share Posted July 10, 2022 I can't recall where I heard that Autotransformers were frowed upon in some CG, SO I went looking for information and found this link in a competing RV forum. It answered a few of my lingering questions and may have some information that you may find useful, once you get passed the discussion about RVIA and NEC codes in there. However, you may already know all of what is discussed in that forum.Autotransformer discussion in irv2 forum Quote +++++++++++_____________________________________+++++++++++ 2021 Ram 3500 2017 Arctic Fox 25W(to be traded??)

GlennWest Posted July 10, 2022 Author Report Share Posted July 10, 2022 (edited) They talking about different units. That discussion is about autoformers.

Chad Heiser Posted July 10, 2022 Report Share Posted July 10, 2022 (edited) Victron doesn’t make an American market 240 volt inverter. None of their American market units will produce 240 volt by themselves while inverting. The only way to get 240 volts out of an American market Victron inverter is to run two of them in split phase (180 degrees out of phase). When the inverters are programmed to produce 240 volt power, both inverters are always active. One is on L1 and one is on L2. They both have to be active to get 240 volt. Magnum makes single inverters that produce 240 volt. Those inverters can be run in parallel to add more power to the system as needed. In this circumstance, the second inverter doesn’t start producing power until the additional power is needed.

GlennWest Posted July 10, 2022 Author Report Share Posted July 10, 2022 Multipus2 48/5000 230v. Change to 60hz and then 240v. Use autotransformer to get split phase. No not American unit but is with software tweet.

GlennWest Posted July 10, 2022 Author Report Share Posted July 10, 2022 (edited) I may get the Magnum units. But 2 of them would be 8800 instead of 10k. But they likely enough. they are on back order now. They are complaints about MultiPlus 2 being noisy also. Read that on Victron Community today.

No not American unit but is with software tweet. Be careful with these setups. There can be some very dangerous grounding problems if the inverter has one leg bonded as a ground.

GlennWest Posted July 11, 2022 Author Report Share Posted July 11, 2022 Thanks. I am aware of grounding issues. Been studying a lot. Everyone is out of stock on Magnum units and talking October maybe.
