Fantastic video. Thanks. I'm planning on doing a system like this for my RV and have some questions. In this dual 48V/5000 inverter split phase setup, if you had a smaller generator, like a Honda EU2200i, which is limited to less than 15A, would the autotransformer be needed or even useful? Without the autotransformer, would the 15A generator load be shared by both inverters, or would one be in PowerAssist and the other inverter only? Also, if these two inverters were set in parallel mode, I understand that the input current limit is doubled, so this system (with PowerAssist on) would only be able to go down to somewhere in the 27A range, correct? Is this also true with them in split-phase? Otherwise, you wouldn't be able to use PowerAssist with small 15A-20A generators or house plugs without overloading them.
Great video. You did not describe how to setup the digital input so that the inverter knows when the generator is running. You did not describe how to setup the Auto generator start on the cerbo.
Thanks for the video. Would you ever set up a pair of 2x120 Multiplus in Split Phase? Or, when using Split Phase should you always use the non 2x120 version of the Multiplus?
Thanks for your question! And in response, not really, it would be cheaper to use the standard Multi-II. Also, it generally doesn't make sense to do a split phase system at 6kW, it's better to parallel the 2x120. This will allow them to function best. It's really only necessary to do split phase if the system power is going to be over 6kW or if you need 120/240.
No one inverter can advertise watt. Watt depends ever from PF of load. Inverter have tot VA. Watts depemds to load. With a resistive load 1000va are 1000w. With a inductive load with 0.7 PF 1000va are 700w. All inverter that say watts, lie. Transformer are dimensioned in VA. Never in watts. Victron say the real data. All say watts, say a lie in some case . If a inverter say 1000w, and is is true with a load ar 1.0 PF, cant be true with 0.8 PF

Rather than try to answer all of this here, please give us a call! It will be much easier to walk through your questions over the phone! :)

It's coming! We broke a very large video up into smaller ones. It's coming soon, still being edited!
Thanks for the video.

They are actually 3000 VA, not 3000 watts.
No one inverter can advertise watt. Watt depends ever from PF of load. Inverter have tot VA. Watts depemds to load. With a resistive load 1000va are 1000w.
With a inductive load with 0.7 PF 1000va are 700w.

Calm down. Victron specifies *BOTH* max kW and max kVA. There are no lies here.
