Hello,
I have a very simple question : what does mean exactly this information in the Manual of the Phoenix Inverter VE.Direct ?
Input voltage range 9,2 - 17 / 18,4 - 34,0 / 36,8 - 62,0 VDC
Does it mean that Input Voltage can be from 9,2 up to 17 V without any issue ? Or does it mean something else ?
These are the absolute minimum and maximum limits.
Keep your design within these limits for normal operation. it is never a good idea to design for running on the absolute limits.
To say it differently, does it mean that it is much more tolerant to voltage fluctuation than basic inverters ?
@GregTabuteau In my view, I don't think it is about fluctuations as that in itself is not generally a good thing. Also to come to such a general conclusion you will have to compare it with many different products first. I think there may be many different reasons. One may be being able to accommodate a wider range of batteries and types from different manufacturers. Not all batteries are necessarily designed equal and Lithium also has changed the landscape.
Ok many thanks. To say it differently, does it mean that it is much more tolerant to voltage fluctuation than basic inverters ?
Hi Greg, most inverters have a DC voltage window of operation, in this case your battery voltage should be inside this window for the inverter to function properly. Your battery voltage should never get close to those limits in normal operation.
