Can anyone give me an estimate of round trip efficiency of the Multiplus II when used in AC and DC coupled on-grid ESS configurations? I am considering the 48/5000/70-50. Referring to the whitepaper on the 3000 VA unit it appears one way would be ~92-94% at peak output.
It would be helpful to have some data in order to consider the implications of using the existing AC grid tied inverter vs. DC Smart Chargers.
Cheers
Richard
