$3100 is better than $3200, and $580 FedEx air mail is a fantastic price for a 100 pound inverter. Shipping by sea is nearly the same but takes 3 months. I am glad you negotiated. I assume that's DDP, and that would include taxes, insurance, and all the fees.
No, the GSL (Megarevo) 8kw is a piece of junk. Not at all the same thing. GSL only resells inverters. They don't manufacture them.
I've been offgrid with the Megarevo for the last 4 months. I'm negatively biased toward it because I'm trying to run a whole house on it and I chose badly (my fault, not the inverter) and didn't understand exactly what I was needing. that and I was down for a week after they bricked it trying to do a remote firmware upgrade. I had to hook back up to the grid twice due to firmware issues.
Yeah, it's not a total piece of junk.

Im getting the update today… I’ll update

Megarevo is made by luxpowertek, the software is not good as their new 12k inverter…
Long time lurker, but chiming in here - I have had this GSL/Luxpower inverter for a few weeks now and may be able to answer a few questions. Currently working on developing a jkbms (RS485) => pylontech (CAN) protocol/interface converter to support my existing lithium battery.
Luxpowertek doesn't manufacture the 12klv inverter. It is manufactured by Shenzhen Sea Star Industry Co., Ltd See the UL Listing certificate.
Are you grid tied? If so, can I message you some questions?
Yes I am, and sure!

Let’s start with the obvious, any issue so far beyond BMS compatibility?
I’d also like maybe some better feedback on build quality and close up photos of the connection terminals if possible. I.e. Are those well built/can accept fairly large gauge wiring?
Thoughts on the management/monitoring app?
No major issues discovered so far, though I am still tuning the system for my use case.
Build quality seems to be very good. No "flexing" of terminals when tightening down connections. And yes, they definitely will support large gauge wiring - the main GRID/EPS terminals use a 17mm socket wrench. The battery terminals are a little smaller, but not by much.
The management app is "ok", and way more informative than what I had access to before. I can quickly view status, alerts, history, and even update some programming.
Terminal close-up pictures attached, as requested.

Thank you for the quick response and pictures, you’re awesome! Are the PV connectors good? I had heard of complaints with other AIO where they were a bit flimsy.
Can you explain a bit your system? I.e. sizing/grid tie/interactive, etc.
Did you have to update the firmware on it? I’m curious about what the process is for those. I work in IT so I’m familiar doing that kind of stuff on “regular” computer/equipment. Just wondering how that works with inverters.
Also, are you happy with how that went with GSL?
The PV connections are decent. Not as sturdy as the connections on the SunPower (ABB) inverter I replaced, but they still feel secure. At least I didn't have to fight with the terminals to get them open, so that's a plus
My system is quite small compared to many others on this forum - 4.2kW rated:
- Panels: 14x SunPower x21, 2 strings (Voc ~475V per string)
- Battery: ~3kW 16S LiFePo4 (temporary, modified 26S3P A123 module), 16x EVE 280k cells coming in soon!
- Configuration: Grid tied (CA rule 21), charge from PV during the day (low grid rate), discharge/offset usage during peak 4-9PM
Note - I do have some physical constraints with attaching the included CT clamps to my main bus bars, so I will be creating a workaround solution shortly. Possibly with modbus emulation via ESP32. I already have a similar converter made for limiting GTIL2, but that is a story for another post.
I mainly wanted to add battery storage to reduce on-peak usage as much as possible.
I did not have to update firmware yet, but I did see an option to update in the app. It shows a list of available filenames, but it is unclear on which is latest, or if it is even for this particular model. Also coming from the IT/EE world, this is probably something I would stay away from in current form, unless explicitly instructed on which file to use.
Overall, I think this has been a great value vs the current alternative options. GSL sales and support has been great. They do provide support over WhatsApp if needed.
Cheap 4-life
My body is 2.63 trillion volts, .07v per cell
What are the constraints?
I've had great experience with GSL sales and support too.
how many kwh total battery capacity in the final pack ?
so is the Luxpower actually feeding the grid once the battery is full ?
what's the CT clamps for if it's grid-feeding ? my impression for the CT clamps are to prevent grid-feed
Thanks
Physical. I only have about 13mm or so of access to the bus bars feeding my main breaker. I cannot get access to my main feed without breaking the tag/getting the power company involved. I found exactly one pair of CT clamps which just barely fit, but only after removing the enclosure and wrapping it in kapton tape. This currently feeds a custom ADC => ESP32 limiter solution, which controls (/controlled) my GTIL2 output.
