Marco,

You can look at the nightime losses for every inverter on the CEC website
http://www.consumerenergycenter.org/erprebate/inverter_tests/index.html.
They have all been tested.

Bill.

I've got a 20 kVA 98% efficient 208/208 isolation transformer connected to
the grid.  With no nighttime disconnect/contactor for the transformer, what
can I expect the nighttime tare loss to be per hour?  Is there a simple
equation to determine this value for any transformer?  Will this number be
affected by the transformer efficiency and/or whether it's a
straight-through of step-up unit?

 

Tankie, tankie,

marco
