I bet you the configuration might be way easier to do using app/desktop.
But the parallel communication between the (up to 10) inverters in parallel would be way to uncertain if you would use WIFI.
I highlighted in purple the CANBUS cables for inter-inverter communication here:

Yea I understand that to parallel them you need the CANBus cable not WiFi. The inverters don't use WiFi to communicate for paralleling. But I believe from the manual that the inverters must be told they are in a group. You have to terminate them properly as well.
 
Will Prowse does it all the time.:)

I wouldn't tempt faith, so far none has been DOA or had a warranty issue. In fact, everyone seems very positive about their new hybrid inverters.
 
Nick told that they have about 100 inverters in stock ready to ship. I had asked Nick, if I would be getting two inverters from the new production run with the GSL logo, color, latest firmware, etc. The answer was no and he sent me some photos of the inverter in stock, which are white and black with the GSL logo, which is the brand name. He asked me if that was okay. I told him okay, that it was only a personal preference for the GSL inverter to match the GSL batteries. I will be getting the same inverter that the other DIY members have received.

Are you going to use these as pass through or to simply feed your home grid??? If you have two of them and need a battery anyway wouldn't it be easier and maybe more economical without needing a bunch of disconnects etc to simply use the battery to enable grid down back up vs using pass through option????

Can you open the top part of the inverter and take some pictures of the insides? I would like to see the motherboard and the inductors, etc.

I took one overview picture and it had focussed on the wrong thing and _everything_ was blurry.

The black plastic part on the left bottom is the PV DC disconnect switch on the left side of the unit.
The 2x parallel PV1 inputs (combined 25 amp) input on the top left, PV 2 & 3 on the middle.
Negative of PV2&3 are combined.

Output of all PV inputs after cleaning ?! go to the mid voltage section (at the top)

Mid DC level inputs from PV with switching gear under the capacitors

On the right side of the inverter, just above the grid entry & pass through points are 2 huge relays. Could not read specs but I am pretty sure they are rated for 200amps
Above that is this PCB which has some 90 amps relays, good to switch the max 50 amp output from this inverter
IMG_20221021_180856791_1k.jpg
This seems to be the brains behind this all.
IMG_20221021_181030975_1k.jpg
I assume on the left are the opto couplers to the rest of the switching boards.
I appears to be an ARM cpu

there is another chip that looks more like a DSP/programmable logic of some kind

That is it for today
Tired, cold & dark outside now ;-)

When enough people get these, I hope someone can do some load testing on them. I want to know how well they handle unbalanced loads, heavy start up loads and how hot they get under full load. Hopefully someone with an oscilloscope can show us the sine wave under full load.

I'd also like to know the idle consumption on these.

I appreciate the comment and the suggestion. I have read it over and over several times, but can't visualize your suggestion. What you are saying is probably something that I should consider, but I just don't understand the concept. The description below should give you an overview of what I'm trying to do. So maybe seeing my situation, you will know, if your suggestion is applicable for me or not.

My house is on-grid and I have a 15KW GT system to reduce my electric bill, which was installed a little over 3 years ago. The only option that my solar installer has ever offered me was a hybrid system with a critical load panel. If I had a 200A panel and could set a critical load panel beside it and simply move some critical load circuits, I would had installed a hybrid system originally. I have (6) electric panels scattered everywhere and I have critical loads all over the house. I have decorated gypsum ceilings without an attic and tile floors over slab, so rewiring the house is not an option.

I decided to wait for a whole house option. My intent is to install the whole house hybrid inverters between the house and the grid. The 200A pass-through should let my house operate as it does now on-grid, which is 99% of the time. The hybrid inverters should continue to operate with the existing solar panels to reduce my electric bill. This is what the GT inverters do now without nuisance tripping or any problems and I want these same features from the hybrid inverters.

We have frequent blackouts, but I would not spend another $20K to have electricity during blackout, even though it would be nice. For me this is insurance in case we have a major natural or man-made event. I want my family to have some power for necessities, if we should have an extended power outage from a major disaster. Like insurance, I really hope that I never need it.

Case is steel (magnetic)

Could you let me know which firmware yours came with? My case is completely unbranded. I’m wondering if there are any differences, firmware or otherwise.

I sent the photos that GSL provided me showing these hybrid inverters laying on tables as you described 'UNBRANDED.""

I had specifically requested the GSL logo, GSL colors and latest firmware. They have one hybrid inverter by itself with the logo showing GSL Energy, I suspected they added it at my request. The case was black and white, not GSL normal colors.

I need to follow up again about the firmware. GRV0423 told me that they are suppose to be updating the firmware for the generator connection to work. I really don't want to do a firmware update. It would be much better, if they did it.

I've had $35000 heart monitors fail on me when I needed a most in my main job when it comes to something complicated and mechanical I always want a backup... If this was true off grid I would just have 2 cheaper inverters But There are 2 things 1 it's a brand new productAnd if it breaks and replacement is 5 to 10 days away... But I also don't want to spend $2000 coming up with a disconnect system... Then it begins defeating the purpose

Just a note..............I got my LuxPower 12kw inverter from GSL in China in 2 days via air. Two days is still a big deal, but if something fails, they CAN and will get it to you quicker.

Some inverters don't support battery-less operation with inverters in parallel. I hope that is not the case with this inverter, but you may find that you are required to have a battery to parallel the inverters. Also I think you must have the wifi dongle in order to configure the inverters in parallel. Make sure you are getting the dongles and everything you need to parallel them. The manual also says that you will need a customer ID for the monitoring software, and that they must create one for you.

Settings for paralleling function in monitor system 1. Set up monitoring for the system, add all dongles into one station. Users can login to visit the monitor system, Configuration->Station->Plant Management->Add dongle to add dongles.

Users can use WiFi/ WLAN /4G /2G dongle to monitor their inverter, and view the monitoring data on computer or smart phone remotely. To view data on smartphone, please download the LuxPowerView APP from Google Play or Apple APP store, then login with their user account.

The "customer code" is a code we assigned to your distributor or installer. You can contact your supplier for their code.

You also need the inverter password to change several of the settings (not all, but some major ones). And, of course, none of this is documented in the manual, but I already had experiences with GSL, so I knew to ask before I attempted to do my install after China hours and on the Chinese weekend when there would be no support. PM me if you need this info.

Make sure they test the battery communication before they ship it to you, if it isn't too late. they will send you a video of them doing so. They put my inverter under a simulated load and tested it before it shipped.......and send me a video of them doing so. This way you know you won't receive anything DOA. GSL is very good to work with, but you do have to tell them exactly what you want. They don't do it voluntarily. They will also update your firmware remotely if you ask them. But, you must have a VERY stable internet connection to do so. My Starlink connection wasn't stable enough, so I ended up having to do the firmware upgrade on my 8kw GSL inverter myself.
