  1. If all you want is to run commands on the inverter, I also have something available you can use: curl 'https://raw.githubusercontent.com/voltronic-inverter/web/master/raspberry-pi/install.sh' | bash sudo reboot now More details in the README Thereafter you'll get the same result by just doing an HTTP call. Very easy to write in Python, Bash, etc. curl -X POST -d 'QPIGS' 'http://127.0.0.1:8080/voltronic/usb' ^ HTTP Post to localhost, the post content is the command and if the response is 200, then that is the data. If the response is 500, it'll contain the reason for the error. 400 error response will indicate some form of client error. If you are adamant about getting your script working, you would need to post some code snippets, but IMO the most likely issue you are running into is python is trying to do some kind of character encoding on the response. Your input I assume is a fixed string: QPIGS<CRC>\r So that should really be consistently correct.
  2. Can you post a code snippet? Did you change your USB cable? - I've had faulty USB cables lead to bad data Is a single command working sometimes but not other times? Or are only some commands working and others not? (this is actually important for a few reasons)
  3. That is a very common pattern. A lot of phone manufacturers do the same with Android updates. The same for cars, cars stop being updated when their manufacturing ends. Keeping software up to date is something the software industry does, the hardware and manufacturing industry does not subscribe to this model. And frankly the only reason the software industry is able to do this is because the margins. I work for a company that did retail only, our margins were low, 3-5%. We built a software devision and within less than 10 years it overtook the retail business which was a giant. The reason is simple, the margins on software are in the 100s of percentage points. When you build a hardware device, there is no money to be made post sales. Not to mention the margins are razor sharp. Some companies get past this by selling hardware that requires a "cloud" plan or similar. Also again, I don't think many people get just how much different the software industry is to other industries because of the chronic undersupply. There are a lot of factors at play that make it VERY expensive when you want to enter the software industry. It depends what you use it for. I use it as a double conversion UPS. In that role, it is better than anything provided by the competition at the price point. In fact I don't even know of other inverter manufacturers that offer double conversion on their inverters. The product is well priced and it sells well. You are being a bit disingenuous in saying that it is crap. There are a lot of crap inverters out there. Tons of them. None of them are making the sales the Voltronic devices are. The reasons aren't their marketing divisions. It is because they've built a relatively good quality product for very little money.
  4. I don't think they are malicious about it. Software developers cost a lot of money to hire. Especially engineers that are comfortable with coding for a platform like the inverter is running. It is probably being written as C code that runs directly on a CPU. It is a lot more tedious to write code for something like that than it is to write for example Java/Python/etc. As for them not fixing the bugs that @Coulomb, I suspect one of two reasons: 1) They don't consider it a bug 2) Their engineers aren't aware of what is being produced by people like @Coulomb. This is pretty common actually and even more so if you are speaking a completely different language (ie> Chinese). The way they operate is pretty close to how 99% of companies work, they put out a product and only make updates if they need to.
  5. If I recall correctly, you have one of the clone inverters. There are some settings that will permanently damage your clone: http://forums.aeva.asn.au/viewtopic.php?p=71752#p71752 Best be careful, because with a clone you probably don't get a warranty you are promised #JustSaying
  6. Well if you are 100% convinced it'll work with that particular software. But I'm not convinced it will fix it... You can install older versions, but given @RichieRich post above, it is more likely a bug that exists in all the versions. Only a hero like @Coulomb would be able to fix this because Voltronic don't seem to make much effort fixing these problems. @DeeJay Whatever you do, please report back when you solve it
  7. I've seen mention of this version, but I don't know of anyone who has uploaded the files anywhere yet... So to be honest, it is hard to be sure because most people here are not running that version. So you were running using PYL before or were you using "ICC" before?
  8. I did the inverter first, then the panel. Once my display panel was updated successfully, it started up but had 2 problems The bluetooth version command no longer worked. "VERFW:" it would return "(" and nothing more I could no longer connect using USB (didn't try serial) To rectify this, I had to turn off power to the inverter and disconnect the battery so it would fully shutdown. Then when I started it up, I still couldn't connect using USB. I held down the USB button and it complained about something, then went back to the main screen. At that point everything was back to normal. All firmware versions are now the latest. I was running 81.40 on the inverter and my panel was the same as other people running 81.50
  9. 35 amps per phase, so 8050 watts per phase. Also note that your incoming breaker doesn't trip immediately as soon as you hit 35 amps. For example: This is the data sheet for the common CBI breaker feature in 90% of homes. Notice that at 250% it takes 1 second to trip (87.5 amps for 1 second). At 100% it takes almost a full minute to trip. etc. Ah I always disabled that option. Also, I find it scary that it is using that kind of relay to switch such high currents. I take it the AC3 rating is laughable low which is why I'm scared of relying on that kind of feature.
  10. Still, consider using a 30 amp breaker for your inverter (and 6mm wire). Worst case it'll trip (Which I can almost guarantee you now it will not). Doesn't make sense to install a 50 amp breaker if your supply is less than 50 amps. Typical 30 amp breakers will allow 7kW to pass through continuously before tripping. That is an enormous amount of power.
  11. Our electrical regulations are pretty good because of the mining industry in South Africa. I definitely trust it over a budget inverter manual. IE> Earth Leakage, RCD, whatever you want to call it was invented in South Africa. Whether they are followed is another story.
  12. 6mm wire is not adequate for 50amps. And you can put whatever circuit breaker you want on there. It'll just trip if it goes over. I have 25amp breaker and I've never, ever had it trip. I would personally not go over 30 amps for Axpert inverter. SANS regulation, in South Africa, supersedes what the device specifies. Also notice that the current carrying regulation depends on the installation method.
  13. I don't think that makes sense, why would you want to pass 40A through a device that can't possible supply that load? In bypass it may be able to handle 40A (I'm assuming because I haven't verified this for a fact), but that is non-sensical to me as I would expect you to match your load to your supply. In South African regulations you would need at least 10mm wire for a 50A breaker. Possible more depending on the type of wire and the installation method (various kinds detailed in SANS regulations). Just so we are clear, the regulation require both the wire and regulations are matched. SANS approved wiring will never be rated for 50Amp+ for anything less than 10mm, but perhaps it isn't clear that both ratings and regulations apply here. As I've said, I've seen install pictures with people using 2.5mm wire with 25 amp or 32 amp breakers. 4mm with 50amp breakers, etc. Completely illegal. Regardless of the choices made, I would definitely size the breaker for the wire. As for uprating a council breaker, you need the council to approve that, your wiring needs to be adequate or uprated and your short circuit impedance needs to be tested again to ensure your breaking capacity is sufficient for the incoming supply. It is a very technical process, 100% would not recommend a DIYer do it.
  14. 50 amp circuit breaker for the supply to the inverter? Sounds like you are talking about the inverter breaker and then about your house/apartment incoming circuit breaker. Quite common in Cape Town & old areas in Jhb. It is very unlikely you have 50 amps per phase from council. 35 amps x3 = 105 amps btw. Short story: You should not in any way mess with incoming circuit breaker. My apartment building is very old and we have 35 amp 3 phase circuit breakers. When I went into the metering room, they didn't have circuit breakers down there. Just a single 90mm x3 wire coming in and being split among the apartments (with no insulation, just open wires). That means if anyone changes their circuit breakers or touches any of the incoming wire, it'll literally keep going until there is a fire. In fact a few months ago the wire caught fire and they replaced the wire (but still didn't add any circuit breakers or anything). In my case the incoming wire into the apartments is 6mm. 35amps for 6mm is actually a bit too high. And this is in Sea Point. So don't think because you live in a "nice" area you are safe. Dodgy wiring from council is how it goes. /Short story Council wiring is often very scary, just don't mess with the incoming wire unless you know for sure what is going on and how to size it. I'm not going to drone on about the insurance, it being a crime, etc. because that rarely keeps people from doing things. But the fact is to uprate the breaker there are a whole lot of things you need to check first. No, circuit breakers are rated for the wire, not the device. More importantly, that inverter on a good day can supply 22 amps. A 25 amp circuit breaker is sufficient. Most circuit breakers have a continuous and instantaneous rating. A typical circuit breaker has an instantaneous rating roughly 1.5-2x the continuous rating (called the curve of the breaker). Not sure if I need to say this, but 2.5mm is not sufficient for wire going to the inverter. I see a lot of people doing that
