I’m fairly certain the single phase Deye inverters only support one Ct because they only need to use one CT because they are single phase and usually only wired to a single phase main panel for grid tie.
If using two CTs (one for each leg) with only one Ct connection to read splitphase power supply then the CTs should be in series. I explain why it’s series on one of the GTIL2 threads on here.
It wasn't listed as a product on Deye until 2020. Their is no picture of a Deye Hybrid Inverter that has the functionality or form factor of the current Sol-Ark, until the Deye clone in 2020. What you can find is inverters in the hands of Sunsynk in late 2018 that are the Sol-Ark 8K model released in early 2018. The Sunsynk guy has peeled off the Sol-Ark name on it and does not mention where it came from or who made it.Just because it wasn’t listed as a product on their site before 2019 doesn’t mean they didn’t make it and sell many of them as far back as 2017 when they say they launched them. Is there anything as far back as 2017 saying SolArk launched the hybrid inverter they had Deye make, or the supposed inverter they made?
Have a link? I couldn't find your posting with a quick search of some keywords.
Just analyzing it in my head, I think series CT would make it sum the current of each leg and multiply by 240V. Parallel would average the current of each leg and multiply by 240V. Either works to detect zero, but I think the second option is needed if setting a target export, e.g. 3kW max permitted.
(Or set a scaling factor as 8484 mentions. Presumably has one.)
Telling someone they are clueless is not helpful. If you truly wanted to help someone like me, the village idiot, please take up the time to tell us idiots what we should be doing, what hardware and software we should be using, as well as how to set it up and keep the bad guys from plundering our cheesecloth network. I'm completely aware of who owns Mikrotik. I'm also completely aware of how limited the typical residential router is here in the United States, (which is why I use a Mikrotik router instead) so in light of the revelation that you know better, please tell me whos hardware I should be acquiring and how is it better than what we have available to us now?More tin foil needed for you. firstly microtik are owned by a Latvian company with 60% Russian ownership. That’s your first mistake as that was on your initial not to trust list but you have it as the core of your network and they use Chinese made hardware based on open router board, which isn’t open at all. Only the software is open source, the hardware is already known to have back doors in hardware. Secondly your inverter that you think is made in the good old USA isn’t, as is most of the hardware for pv Is made in China Or has Chinese DSP, processor or an arm licensed mm, I have great respect for my cousins in the USA but you seriously need to take a look closer to home sometimes. You think you have a good understanding of networking and such because you are using a certain brand “based in the us” you honesty don’t have a clue.
I agree with you 100%. I see no reason why a hardware manufacturer cannot offer a simple locally administered solution to be able to monitor one's solar system on a home network and NOT NEED internet access, cloud storage, a third party or a complicated web interface to be able to make sure all of your panels are working properly, everything is "normal" and there is no need for any further interaction.I'm a retired, software development engineer. I will NOT connect to anything outside my home. Any data you 'give away' will be used to track you and be sold. The iComfort on my whole-house heat pump is an example - I refuse to allow it to connect and store my heat/cool stats outside of my home. You might think - who could ever connect my 'annoymous' heat/cool use or SolArk solar stats or X or Y or Z to me - but you'd be wrong. These bits of data can be leveraged thru analysis and often connected together and sold or used to market you or used for nefarious purposes down the road. The way AWES (Amazon Web Services) and Dell (EMC/Vmware services) works is that virtual servers can migrate and/or be replicated and/or backed up anywhere in the world. You can have a primary service here and replicate/backup there. Personally - I just won't buy a product that requires off-site interconnect to be used.
I don't think they (Sol-Ark) are doing anything that is nefarious, just a business decision. We may not like it but the product, going on 2 years now with my 12k, is rock solid and worth it and I don't regret it. Sure I may have some buyer's remorse since I didn't stumble upon the DEYE 1st given the potential savings but I am not going to lose sleep over it.You have a right to be concerned about this! If they are making a track record of doing this then what is keeping them from dumbing down future "updates" on their current hardware in the future.
I don’t need a picture to confirm that Deye was making single phase hybrids before SolArk wanted splitphase. Most inverter manufacturers makes a single phase version before splitphase, that just the way it happens. Both pv magazine and Deyes website confirms that Deye launched single phase 8k hybrids as early as 2017.It wasn't listed as a product on Deye until 2020. Their is no picture of a Deye Hybrid Inverter that has the functionality or form factor of the current Sol-Ark/Deye clone until 2020. What you can find is inverters in the hands of Sunsynk in late 2018 that is the Sol-Ark 8K model released in early 2018. The Sunsynk guy has peeled off the Sol-Ark name on it and does not mention where it came from or who made it.
You don't need Internet access to program and use the Sol-Ark. You can do everything from the front screen and never hook it up to the Internet. They even offer software update dongles for people who live out in the sticks and have no internet. The only issue is that you cannot remotely monitor or store production data without their internet servers unless you want to try one of the third party devices. I will buy one of those until I actually see it being demonstrated on a Sol-Ark.I agree with you 100%. I see no reason why a hardware manufacturer cannot offer a simple locally administered solution to be able to monitor one's solar system on a home network and NOT NEED internet access, cloud storage, a third party or a complicated web interface to be able to make sure all of your panels are working properly, everything is "normal" and there is no need for any further interaction.
My beef with Sol-Ark is they are a premium priced brand and they don't offer this simple solution. SolarEdge has the same problem, and for those of you (like me) who are choosing to get away from Google Services by opting for a "dumb phone" or a de-googled phone, many of these phone apps that are required to monitor your solar system also require the third party intervention services of Google. Add in Chinese servers and the constant datamining of Google and we have no privacy rights.
My 18 year old Trane 19i HVAC system needs to be replaced. Most of the comparable systems with similar efficiency ratings have interconnected and networked services that are required to be "online" for a warranty action (should one arise). So I've spent the last 6 months looking for a replacement system that is at least as efficient, will use my existing thermostats (there are 5) as well as the existing infrastructure and not need to be "monitored" externally. Right now I can log into my Aprilaire 8826 controller and program any or all of the thermostats from any computer on the LAN and it doesn't require internet access. So it's not just Sol-Ark who is adopting these idiotic business mandates. It seems as if our next toaster will require internet access to work properly.
I'm just raising a ruckus to inform all of you, so you won't make the same mistake I made by purchasing a system that requires access to the Internet which might involve Chinese servers to fully function with monitoring.
My mistake it was at second life storage not here.
Although the GTIL2s CTs are only for limiting. The GTIL2 has options in its settings to limit the amount it produces but not to limit its export. It just won’t export at all when using limiting, so you might be right about the Deye needing the CTs to be in parallel due to the other things the Deye uses the CTs forI'll measure my Voc at noon today. I'm pretty sure it is right up there at 65V. I'm taking it that these inverters are meant to work with modern panels that run at some 32V (64V for two). On the limiter side, that is working perfectly! I have mine set at a 30 watt buffer. And that is just what...secondlifestorage.com
you dont have to connect the sol-ark/deye/sunsynk to the internet if you choose not to do so.Well I am now leaning towards a more simple inverter (non cloud-connected) setup utilizing some of the equipment I already have: 4 x 230W, 24V panels and a 40amp AIMS Power charge controller (model: SCC40MPPT)
I need to at minimum enough power to run the well pump drawing 6 running amps (not startup) @ 240V plus the chest freezer and fridge.
