*shrug* I'm happy with GSL so far. The inverter arrived quickly and is working well in my application now that I've corrected my installation errors. GSL has been responsive to questions and it seems like a nice piece of equipment. I haven't needed to do a firmware update yet because my simple scenario is working fine, but I'm sure I'll do that eventually. No complaints here presently.
 
Super happy with my LuxPowerTek inverter so far. I'm not AC Coupling. I have 40kwh GSL powerwall type batteries, 10.2kw of PV and I'm grid tied to receive grid power (not exporting power back). Everything working correctly. I love being able to use as much of the grid as I need rather than being limited to 38amp like with the Megarevo I had before. My batteries are all charged by 11am (since the time change) and I'm getting so much more power out of my PV with the 3mppt setup that the LuxPowerTek has rather than the 4 smaller mppts of the Megarevo. Setup was relatively easy, although the manual wasn't set up particularly well to figure out what setup to do for what instance (some lost in translation between Chinese and English).

Is GSL still the recommended vendor to purchase from?

Not sure what other choices you have except maybe Liniotech and I think they are marking these up. My experience with GSL support has been very positive.
 
Is the firmware the same across different vendors? I have one on order from another vendor. It's labeled as LuxPowerTek, not GSL.
 
Im still happy with my GSL12k Hybrid inverter for what i need it to do, to control my 3 tesla powerwall to discharged and charged only between 20%-90%, with my DIY 28.5 kw Lifepo4 battery as energy buffer And Trying to use Daly Bms and Daly interface board to communicate with the inverter, but GSL support is lacking at the moment.20B3E801-A6AE-4AC5-9EC2-A7BD6C70BF36.jpeg
 
Luxpower Tek has an informative website with product, news, support, download and contact us. This same link also have a step by step installation video for a Luxpower Tek hybrid inverter. Under product, there is a link about the new LXP 12K Hybrid Inverter.

What is Hybrid Inverter - Hybrid Solar Inverter

The hybrid inverter is a smart inverter that can store excess solar energy in a battery system. It combines solar energy and batteries.

Yes, and there has been many firmware releases. As fromport pointed out, they are without any firmware release notes, so no idea what was supposedly fixed, if anything. After weeks of firmware updates, to my knowledge, these inverters are still not performing all functions per their advertised specifications. I don't even know, what reported issues or problems were actually fixed.

One might ask GSL or Lux for the actual firmware. My experience is that the release notes are included in the firmware package. I'm betting that Lux has them and could hand them out.
 
I watched Will Prowse review on this Energetech Solar battery 10KWh 51.2V 200Ah LifePO4:

Afterwards, I decided to click on the link provided by the description for the video: https://www.electriccarpartscompany...-solar-energy-storage-system?ref=h-cvbzfahsek

I saw something in the battery description that would never had occurred to me as a potential problem:

1668184023273.png​

I had no idea that this is a possible factor in selecting batteries nor had I ever seen in another advertisement for batteries any information that the batteries can or can't use AC coupling.

I read one article from an inverter manufacturer that recommended sizing batteries equal to or more than the inverter capacity, which was my intention as a first buy to match the inverter capacity. Later, I would buy another set of batteries to double the inverter capacity.

Energetech Solar requires (not recommends) one 10KWh 51.2V 200Ah LifePO4 batteries as follows:
1. Requires one unit (10Kwh) to run a 3 kW Inverter.
2. Requires minimum of two units (20 Kwh) to run a 6 kW Inverter.
3. Requires minimum of three units (30 Kwh) to run a 12 or 15 kW Inverter.

Remember these batteries don't AC couple, so the numbers are for inverter only using PV only.

I read the "NOT compatible with AC coupled systems" as either:
  • Does not work on a basic grid-tie inverter (non-hybrid), as there simply is no way to connect batteries to them
  • Incompatible with many commercial non-48V grid-tie/hybrid systems in the market, as they require 300V battery banks.
In any case, a 48V battery is a 48V battery, and will work with any system in a compatible voltage range.

Here is the link to the actual ad for the batteries that was listed in the video description: https://www.electriccarpartscompany...-solar-energy-storage-system?ref=h-cvbzfahsek

I would never had thought that this was a problem either, but the language is very clear and hopefully wrong.

GSL did stress compatible batteries in their description. I had assumed that compatible batteries was only a BMS protocol thing. I didn't think that it meant listed for hybrid inverters and AC coupling. Energetech Solar states specifically that their battery is compatible with hybrid inverters, which I didn't know was a thing nor did I know that there are special batteries for AC coupling.

Don't think too much about this.
It's like saying you can not use a 12 volt car battery to power your AC home grid DIRECTLY
You know how Americans like to sue everyone/everybody. it is just a disclaimer for the stupid and the people willing to sue.
It basically tells you: this is not the functional equivalent of a T powerwall

Re: GSL compatible batteries - it's a BMS thing. While I was working out a converter for my JKBMS, I set the GSL to use lead acid. Not ideal, but works. Now I have a protocol converter setup, my JKBMS communicates over Pylon, which the GSL inverter does support. Without a doubt, this is 100% not a supported config. Standard disclaimers apply - YMMV, use at your own risk.

I believe you can use any type of battery as long you inverter/hybrid inverter can shift frequency when the battery is full…

Frequency shift only applies if you are AC coupled to PV, are off-grid/absolutely cannot backfeed, and have no dump load. In a grid-tie situation, excess generation simply gets sent back to the grid.

I believe everyone should know that if you are grid tie it will send back to the grid…

It say plug and play offgrid solar battery. Im saying that you need a inverter that can shift frequency…BF32C3FC-BAEB-481C-80AF-C56683A3FD11.jpeg

...is it correct to think that all GT inverters are required to shut-down when frequency is outside the margin per UL1741, but the one with UL1741-SA can throttle the current ?

correct.
UL1741 is just an on/off scenario
UL1741-SA is gradually regulating the output to the point where eventually it can be shut off.
