An inverter spec....
A typical for example, ASY24 from Fujitsu, shows nominal 7kw, "(.9-8KW) " Their brochure says "vram increases maximum output of the compressor"
I have asked manufacturers many times WHEN EXACTLY IS THIS INCREASED POWER over the "nominal" power available.
For example, is it.. all the time? for a set period at start up? Answers Ive had allready include, "all the time but not allowed to state as nominal power as doesnt fall into energy efficiency rating", and "all the time that its capable, but cant say when that is". and "thats how inverters work,"
If it IS all the time that the system is capable, how does one find out the conditions that allow this. Would be nice if your replies just say, high heatload on the evaporator, requiring full performance, but im doubting that otherwise why dont they state nominal" and maximum as the same.
