[RE-wrenches] 1/2 wave loads

[William Miller]

Friends:



Half wave loads would be those that pass through a single diode or a device
acting like a diode.  A resistive load like a heater would not be
considered a half-wave load.



AC-DC power supplies have diodes but if operating correctly will provide
full wave rectification.  Switching power supplies should also use the
entire waveform although they can introduce noise onto the feeder.  These
power supplies are not typically large portions of a residential load.



Please forgive me if I misunderstand the question, but basic electrical
theory would confirm the above declaration.

As I understand it, Heater loads are the main issue.



Toasters, toaster ovens, hair dryers, aquarium/terraium heaters etc.



But I defer to others that know more.



And I’m double checking to see if the information that I received is
accurate.



And of course assuming it is correct, is there anything to be done about it?

Can you give an example of a device that is powered by a half wave power
supply that is large enough to create an issue for the Envy inverter?



That would help track down why some loads cause the over load error, etc.



Thank you,



Maverick

Hi all.

I’ve recently been made aware that the fortress inverter isn’t too happy
with 1/2 wave loads.

I’m wondering if this is an issue with the AIO or solark?

Thanks in advance

Jay
