Hello everyone! I'm new here and really enjoy the extensive knowledge Victron puts out to its customer base!
So, here is my situation. I have the need for 240v split phase (SP) on my RV due to the installation of a 240v inverted mini split HVAC system. I've heard that there was a method to get one Multi (L1) to passthrough/charge and another Multi (L2) to invert from batteries to make 120/240 SP when incoming power is only 120v single (Obviously not as efficient but with solar and many kWh on hand it could work). I've also seen Victron's recommendation to use a 240v inverter coupled with an autotransformer to make 120/240 SP but that would be problematic when the incoming power is only 120v because I would need an autotransformer to make 240v. That's two autotransformers! Not to mention, I already installed two 120/3000/70 Multis configured in SP.
Now to the question, using the method above where you have one Multiplus passthrough/charge L1 and the other invert for L2, how do you program it?
Or another option would be to utilize a skylla-ip65 120/240 charger for when incoming power is not ideal?
Hope this makes sense. Thanks!
