Victron autotransformers .
I have no experience with these autotransformers . Does anyone have an idea of the idle consumption of these ? We are finalizing the design of an off grid residential solar system on a very remote island . Customers needs to have 110 and 240 v output . Local grid (not yet available) is 240v single phase 50 Hz . Customer generator is same 240v/50Hz / Single phase / 12 Kva. Planning to install a Multiplus 48/8000 240v and a 100A Autotransformer . Customer's house is wired with 2 circuits : 100 and 220 V . In order to fine tune the daily Kwh consumption, I am trying to get an idea of the consumption of these transformers . any idea will be highly appreciated . Thanks .
