Terrible Signature Solar / EG4 18Kpv Experience - Returning and Replaced with Sol-Ark 15k

Quattrohead said:
Yes could some of you please try some surge loads off grid with the 18K. It's not so much about whether you can trip it from overload but how does it handle big load switching on and off for you? Look at your lights, monitor voltages and let me know

The result from the firm ware update on you tube with my surge improvement.
 
Is that dust collector 3 or 5 hp?

And will it handle a 3 hp table saw or a 3-5 hp planer starting up at the same time it’s going?

Once it's going I'm sure other loads will work but haven't run it to the test yet. It's a 3 hp but still, there is a lot of surge starting it with the cyclone prop inside. I'm trying to figure out how to wire my smooth start on my Quincy compressor. It how ever is a 5hp belt driven QT5 2 stage 80 gal compressor. Before the update it tried to turn it over but the KPV would shut off. Now it turns it over but I turn off comp after 6 seconds or so, it don't seen to turn it quite fast enough yet but it don't shut KPV down either. Not sure if I'm getting equal voltage on both lines. I don't have the CT's hooked up any where and don't know if that would help or not. In any case it is an improvement with the surge update. May be a sunny day might help, don't know.
I just wanted to show the off grid result.

Wow I did not realize this post was under this thread. I know it went off topic a few times so I've just kind of let it be.
 
It does show that the firmware update has made a big difference for surge capacity. I wonder what they changed in the software.

I'm wondering if the added surge = shorter life. Why was it set that way before? Safety margin for the unit?

Yeah okay you are able to start up that savage load easy enough but what are your lights doing at that point?
This is my question, how is your voltage regulation?

I did not notice any flicker. The shop lights are T-8 florescent,(4 lights 4 bulb each) The washing machine, a few lights, the wife was taking a shower so the tankless water heater was on and may be the well pump. Did not notice any issues like from the 6500ex or my Growatt split would show.

It was running an electric tankless water heater and it started that thing up? That's pretty impressive.

Good test, nice video, well done.

Next test should be sustained loads under battery power, no solar or grid input.

I'm going to do another, with more load soon but that is kinda what I just done. I did not mention the other loads that were running then in the house, I'm bad on that to not mention in the video. This video thing is kinda new to me.
