Kirk,
Unless I remember incorrectly, a single diode gives half wave
rectification, full wave rectification requires two diodes with a
center-tapped transformer or a bridge rectifier. Half wave rectification
injects a dc current on the inverter output; that is why some inverters
don't do well
Hi KirkI don’t have one who’s using the LUX between the grid and loads. Have you seen this issue?And from your comments, I guess the inverter doesn’t use a relay but some other device to pass through the grid power? Would it be the same for a generator?ThxJayOn Jan 30, 2025, at 6:59 PM, Kirk Hera
Fortress tells me they just released the latest firmware to deal with
half-wave loads. This version was put out for download a few days ago.
In my case, they say it "might" help (CFL to) LED retrofit lamps from
flickering when switching grid pass-thru to inverter AC. I am dubious. but
I've since r

I can’t
I can’t remember if I sent the update.
We identified the load as a Japanese bidet. Once unplugged everything is
working normally.
So whatever people want to call the 1/2 wave. It’s what multiple OEMS call it.
If I can find an oscilloscope I’ll send along what the wave form looks like.

I think about resistive loads as “in-phase”. Half-wave seem like they would a
load with a diode blocking one side of the waveform.

Ugh, let's stop using jargon to describe something we don't understand.Performing half wave rectification of a sine wave doesn't make a new type of load called 1/2 wave load...Half wave rectification has been used by some electronics for years, but is uncommon and inefficient. How an inverter manuf
Hello Wrenches,
I wanted to look into this to see why a diode might be used in something
like a heat load. William is right that a typical heat load wouldn't be
considered a 1/2 wave load. However, some power level switches (like the
little knob on the hair dryer) may engage a diode that will al
Hi HowieThat’s great info thanks. They never mentioned that to me. And I’ve not heard about an actualHardware issue/fix. The latest firmware 1E1E is supposed to “fix” it. It also requires a separate firmware update for the display which you have to do in person, stupid. JayOn Dec 18, 2024, at 9:05
I installed a couple of EG4 18k inverters off grid this past spring, made
by LuxPower as is the Envy. They look very similar both visually and
programmatically. Withone install, there has been a steady problem of the
inverter shutting off when the client uses a hair dryer. The other client
has not

Having worked in power electronics monitoring and measuring for over a decade, I can say I have never heard of anything being referred to as a half wave load.On Dec 18, 2024 15:52, Jay via RE-wrenches wrote:Here is what I understand 1/2 wave loads to be. As I understand it, Heater loads are the ma
I will add that I’ve heard privately off list that it’s actually smaller loads
that seem to be the issue.
And larger 1500 watt electric heaters seem to work ok.
I’m wondering if anyone else has come across this issue and I guess more
importantly is there a fix?

Here is what I understand 1/2 wave loads to be.
As I understand it, Heater loads are the main issue.
Toasters, toaster ovens, hair dryers, aquarium/terraium heaters etc.
But if there are other things pls let us know

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,

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
