Hi,
I have a 15kVA Quattro with all loads connected to its primary output.
When I turn on a few heavy loads (oven, stove, electric kettle), I can get to around 14kW of power draw, as measured by the Quattro. At that time, some of the energy will be coming from the DC side and around 2-3kW from the grid connection (which is limited to 8kW).
When that happens, I am getting an overload warning from the Quattro. Why is that? I thought that if it was passing through current from the grid, it can easily stay under its max output limit and the overload alarm should only sound if the grid failed? Or am I missing anything?
