So you are saying, two inverters run to separate legs, L1 & L2, will not give me 230v when using the proper breaker which engiages each leg? Don't see how 110 + 110 doesn't equal 220. Know this has been suggested on multiple times.  

He's saying that there's no guarantee. I'm sure both manufacturers offer inverters to do it, but I'd bet mucho dinero that not all the inverters in their inventory will do it. You really need to get on each manufacturer's help forums, or contact them directly, to get the truth.

if it is on the same phase it will not be 220, if it is two phases then it will be 220, on a single phase panel, 

I know it sounds stupid, I would have called it a two phase panel, and call it a three phase panel when dealing with three phase, but I didn't write the books

This one will give what you need, but bear in mind total output is 4400 watts for combined load. But up to 4 can be paralleled with a router. But still think separate 240 and 120 volt inverters would be easier.

Didn't show up what you were posting about. Think you were referring to the Hybrid Magnum

That's right Glenn, that's what I'm saying. If Inverter A is 120 Line to Neutral and Inverter B is 120 Line to Neutral and they are wired together and in phase

GET THIS                                 L1 to L2   EQUALS ZERO               NOTTTTTTTTTTTTTTTTTTT 240

I have seen parks miswired that indeed provided two legs of 120 Line to Neutral  BUTTTTTTTTT a volt meter read ZERO L1 to L2.

In true 120/240 Single Phase Three Wire service like the Utility or a Genset (or an Inverter for that matter) might be configured and provide its 120 L1 to Neutral,,,,,,,,,,,,,120 L2 to Neutral,,,,,,,,,,,,,,,,,,240 L1 to L2...…..That's because L1 and L2 are 180 out of phase. When L1 is + 120 L2 is - 120 therefore its 240 L1 to L2.

NOTE all I'm saying is you CAN NOT just buy any old 120 volt Inverter and another 120 volt Inverter and unless they are phased and synchronized together for that purpose YOURE NOT GONNA NECESSARILY GET 240 L1 TO L2 !!!!!!!!!!!!!!!!!

That's NOT to say you cant buy a true 120/240 Volt Single Phase Three Wire Inverter (same as a Genset or the Utility) to get BOTH 120 and 240 orrrrrrrrrrrr you cant buy two units that can be synced and phased properly to do what you want. Check with Victron and Magnum NOT what someone including myself may guess or think...……..  

FYI a typical residence (and many RV parks) uses what's correctly referred to in the trade and among electricians and us electrical engineers as 120/240 Volt Single Phase Three Wire where its 120 L1 or L2 to Neutral and 240 L1 to L2...……...Many industrial and commercial facilities use EITHER 208 Y 120 Volt Three Phase Four Wire,,,,,,,,,,,,,,or,,,,,,,,,,,,,,120/240 Volt Three Phase Four Wire Hot Leg Delta...………...

Hope this helps and doesn't confuse you Glennn LOL, what you need can be done just be sure you buy the correct equipment if you need BOTH 120 and 240...because 120 + 120 may equal ZERO and NOT 240. This is AC  NOTTTTTTTTTTTT DC

Happy Thanksgiving

Yes, very aware of that unit. That is what I am debating about. Likely need 3 of them. Victron is 5000 watts so might get by with two of them. Several on here wire two inverters to separate legs. You telling me that will not supply 220.
