Could you elaborate on what type of information you are looking for? I personally use Solar Assistant, which does have the capability of using this, in addition to other inverter specific information.

I don't think anybody here was downplaying your contribution, or claiming your efforts were trivial. Though, I hate to be the one to point out that it seems this is exactly what your are claiming in regards to syssi's "simple serial reading" work, yet still valuable enough to start your repo on...

Could Ethernet work? https://esphome.io/components/ethernet.html

Now this is what open source is all about! Thank you for your contribution! Do you plan to fork the repo in github? Also, it's great you have an isolated DC-DC converter module explicitly listed, fused appropriately on the input. I mentioned this in another post, but as a reminder to those...

I'm sorry, but this is not at all how the open source model works. Open source developers are free to provide as much, or as little contribution to a project as they see fit. Send over a pull request to fix 1 typo? That's fine. Dedicate 8 hours of personal time per day to build entire new...

First, I'd like to echo the same gratitude in regards to uksa007's original contribution(/improvement) as an open source solution. Open source is NOT at all about money, patents, or copyright. It's about contributing to an idea, bringing it to the next level, and sharing how it was done with...

@edgecrusher - sorry been busy, but yes, I found it. Overall code is embarrassingly bad, but here are the main snippets (removed some custom offset code to help with clarity, some vars may be 'missing'). Main loop, keeping registers up to date: #include <ModbusRTU.h> //...

I'll see if I can write up something this weekend, the code is still sitting on my old laptop (and is embarrassingly bad!) Background: Originally needed a solution to control backfeed on a GTIL2 inverter without the use of the original CT clamps. If unfamiliar, the GTIL2 functions in a closed...

Would you happen to know how many amps the Jk-BMS V-BAT port is rated to support? I was considering using this at first, but since I did not have specs, decided to connect my DC-DC directly to the battery instead. I'm pretty sure it would have been fine to power from the port, but my main...

You should be fine with a common reference ground. The key reason for my selection of an isolated converter is mainly what happens in the rare event of oscillator failure. In 'cheap' non-isolated buck converters, an oscillator failure will cause input voltage to pass through the coil, causing...

Multiple routers can be quite limiting, but if it works for you, great! A better way to prevent the inverters, SA (or anything on the wireless network for that matter) from accessing the internet would be: Set up an additional SSID for SA and your inverters Configure new SSID to operate on a...

What URL are you using to access SA? If it is the 'public' one, obviously it will not have any data to relay if the internet is disconnected for whatever reason. Have you tried accessing it via internal IP?

One cycle is typically calculated as a full charge/discharge equaling your battery capacity, not necessarily all at once. For example - charging/discharging 10x between 80-90% == 1 cycle. In regards to degradation, this is a complex subject, as there are numerous variables to consider. Just...

You can, and even easier if you flash ESPHome to it, assuming you're already running the Home Assistant ecosystem. I do this with a similar device. Just be aware - some are able to read voltage state, some cannot. I have not yet done the research to see what this particular device is capable...

Many larger boats/sailboats intentionally *add* weight to the keel in the form of Iron or lead, specifically to improve stability. It would theoretically be possible to have a "lithium keel", which would consume no additional space onboard... Of course, this depends on the type of boat - ideal...

I've been using Solar Assistant with my GSL inverter for a few weeks now. By default, Solar Assistant will pass through battery stats as provided by the inverter. When using it in this way, the battery does not need to be directly supported by Solar Assistant. However, Solar Assistant...

Welp, so it finally happened. The other night, I discovered a few settings have mysteriously changed, causing energy to be drained from the battery at night and fed back to the grid, when I don't want it to. Specifically, 2 settings... Peak shaving went from enabled => disabled, and "charge...

In some cases, GEN ports are physically incapable of bridging itself to the grid, as there is absolutely zero reason to do so, and it brings in major safety concerns. Furthermore, it is unclear on how this port will interact with the inverter when it comes to UL1741 features - in a grid-down...

That's fair... Not sure how many strings you have, but maybe switch one of them to GSL first to gain confidence in the system? That way if you do find the need to bypass, you're not totally out.

GSL is the OEM, LuxPower is the ODM. Similar to how Deye is the ODM for Sol-Ark (and others). If unfamiliar, here's a very simplified explanation: ODM: Original Design Manufacturer. This is the company that basically creates the reference design, often sold to other OEM's as a "white label"...

What are your string voltage(s)? If you are able to move over your PV to the hybrid inverters, that would be best. I find the LP inverter to be quite a bit more efficient than my original grid-tie inverter. It also removes the added complexity of AC coupling.

It's related to the MPPT trackers. Basically what is happening during these early morning scenarios is open circuit voltage will initially measure beyond 140V, which turns on the system. However, right when the panels experience load with very little sunlight available, there will be a voltage...

This morning, I noticed my inverter relays were clicking on and off every few seconds. I don't really spend much time in the garage, so I haven't really noticed it before. The fix was simple - increase Vpv so the inverter does not attempt to pull power from the panels when not enough sun is...

IMO it's not that difficult, but this is coming from the perspective of someone who designs hardware/software for a living. If this is not your area of expertise, there will be a steep learning curve. Definitely not beginner friendly, but it is doable if you spend enough time on it. Key areas...

Custom hardware/software, not something that can be bought off the shelf as a complete unit. It is ESP32 based with CT clamps connected via ADC over SPI, sending simulated meter info to the GSL inverter over RS485. I am emulating the Eastron SDM630 meter, as this appears to be the only one...

I am currently using an isolated 48V => 5V DC-DC converter. Search for VRB4805S-6WR3 - This part works perfectly for me. I avoid non-isolated converters for this amount of drop-down, as a component failure (transistor or oscillator) will send full pack voltage to the ESP32, and potentially to...

Transferring circuits to a new panel is no fun, so if you have the capability to connect your main service line (after meter) directly to the GSL GRID port, and EPS output back to the main panel, that would be ideal. I tried looking for something to basically replace my main 200A breaker with...

I am grid tied, but only have a few circuits on a 50A breaker'd CL panel passed through from the EPS port. For all intents and purposes, behavior of circuits on the CL panel will be identical to a full 200A passthrough, just at a smaller scale. Do you have any specific questions or concerns...

I haven't done this yet, but what about changing the network setting from TCP Client => TCP Server? I don't see any other way to 'disable' calling home, but this should be just as effective, and will still work with DHCP.

FUD == Fear, Uncertainty, Doubt. Comments do not need to be negative to be considered FUD. Wow, ALL hybrids? I guess we shouldn't use them at all then. Again, specifics. Echoing the sentiment from @fromport. Parallel inverters are possible, just read the thread without stopping at the...

Ok, so in just a few lines, here's a quick tally: - Company "might" be able to change settings / turn off power - How could this have possibly passed UL? Government was paid off! That must be it... - "people" are having problems, in more than one thread - Maybe the manufacturers don't understand...

Bad press? Please share. I'm curious to how a few negative experiences represent the product as a whole. As for myself and quite a few others, I have nothing but good things to say with all things considered - *especially the price*. Is a Sol-Ark 15k better? Probably. Does it justify 2-3x...

Of course! Use the search term "ABB SACE S3 shunt trip". Here is one example which happens to include proper photos, though pricing is not the best - https://www.ebay.com/itm/203597758677 (For example only, I have no affiliation to this seller!) A few tips when searching for a shunt trip...

I understand the intent, though behavior will likely not be as expected at best, and potential damage at worst. From what I understand about the inverter internals so far, the only difference between the generator and grid port is which way the internal relay is flipped. If you want the GSL...

This is why I said unlikely, but there is still that 0.01% chance in 1 specific scenario which likely does not apply to anyone here, or anywhere. So, nearly impossible. Scenario, all must be true: - Relay contacts welded stuck (extremely rare, but possible w/ high-current arcing, spring/metal...
