GSL 8k non DEYE installation help! (Megarevo??)

I'm not upset with the price. I've been on the waiting list for the LVX6048WP for a while, and figured this was a good value. Now that the WP price has gone up to $2200, I'm happy I at least got the ball rolling with this GSL. Maybe I'll get lucky and it will show up with the new screen?
 
I was in the exact same boat. I was on that waiting list and couldn't wait any longer. I thought I was getting a Deye for the same price but that turned out to be incorrect. I like the specs of the Megarevo a little more than the LVX6048WP since I was at the max for the PV input on that unit. Now I have expansion room. The Megarevo seems to be a little simpler on the features though.
 
I just wanted to add another PDF I got from GSL. It doesn't say too much, but it could provide some insight if others are looking into this inverter. (Notice even their sticker shows megarevo part number (R8kLNA)

Hi. I just received the same "Megarevo" when I ordered a GSL inverter. Not happy with GSL, they are not honest about their product. If it is not their product just say so and I would not purchase it. Firmware and LCD are so outdated. I bought a Sacolor/Growatt which is much cheaper and it has a better interface. I hope it is reliable because I am off grid.

Hi Reecie 15, Not sure your going to like it's off grid function. The Megarevo is a grid tied inverter and when it operated in off grid mode, it shuts down for about a minute trying to do a PV isolation test at exactly 5:30 am. There is no option to disable it as of yet. When grid is present, it instantly switches over to grid to do the test which takes exactly 5 minutes, when complete, it instantly switches back to battery use. You would not notice it's doing the test, unless you have a energy monitor on the grid side. This is what i have observe, pretty sure it happening to all.
 
ARM: V1.03.06
DSP: C1.04.06

latest, nope it did not fix it. They are under the impression that this is normal. I have been hounding them about a fix. Explaining to them that no one wants an inverter that shuts down, because it is off grid. Let's hope they listen.

Can you provide who you are contacting? Maybe enough people email it would be fixed

It is with a Sales person at Megarevo via Wechat who then relays it to i guest the support group. But it is very difficult with time and language barriers. But something is something.

Hi MNRosado, I have not connected it yet. just powered it up with a battery to look at the user interface. this is not user friendly. Apart from the PV isolation test is there any other issues or problems?

I haven’t had a single issue with mine being grid connected

One more annoying issue, is it's slow switching when in grid-tired mode. When the grid has a hiccup, the inverter switches to ESP (UPS) mode and its not fast enough, so i lose internet and other electronics in the home, such as the DVR. Slvrsky07, most of the issues occur when the grid fails. When in Grid tied mode a there is no power failure it's a charm take the grid away and it forgets it has a brain.

That would not be an issue for me, but I am not sure I understand the 5:30am PV Isolation test. Since I am off grid what should I expect to happen at 5:30am? A full black out for 5 minutes everyday?

What i have observed is that when it does the PV isolation test, it switches to grid for exactly 5 minutes and it switches very fast so you would not notice the testing. I have a energy monitor on the grid so this is what i observe. Now when you are off grid, The inverter searches for grid, turns off the load, does not find the grid and comes back up. It does all this in less then a minute. You can clock it to see exactly how long it takes.
 
Hi MNRosado, I would like you to do me a favor. I reached out to a supplier in China about the pv isolation test issue, and she sent me a video. Could you please look at it and tell me if it works? I still don't have the time to install my inverter.

I have toggled that setting in the past, but wasn't sure what it did. I will see if I have it disabled, and report back tomorrow morning.

I wish there was actual documentation to the rest of those settings too.

Would you please also ask them when they will be adding generator 2 wire start support?

And the smart load settings for Load 2 connection. Or to put different way the ability to program the output to turn on and off based on different parameters or SOC of battery.

Thanks for the video. I disabled the leak detector and also will report if it makes changes.
