Finally returning RS-485-2 to SolarEdge leader (as it must be for my two inverters to aggregate and share reporting out to the SolarEdge monitoring site. In order to provide a home with both PV and battery, another 20A string would need to be added, and in this case, an MPU would be required. I not installed correctly then who knows. All rights reserved. powerlimit * rated AC power is always slighly bigger than AC power (especially mornings, when AC power is still 0 and status is THROTTLED, powerlimit is > 0). You could the same with a RPi but the airport express is cheaper and doesn't need any configuration. The solar edge meter installation guide example seems to suggest that this should be Dev=MTR Prot=WN but I don't really know what impact that has. With our DC-coupled solution, modules per 20A string is not a limiting factor. The OP apparently has two 11.4kW inverters and if they were undersized by a factor of 1.35 that means he has 30.8kW of array power. Once the severe weather ends, your customers system will automatically return to its previous Backup Reserve settings. Four more panels can be installed along with our standard, 11.4kW inverter, giving your customer 11.25kw, or roughly 15% more power, from the same breaker. . Nie modbus responds and Home Assistant gets values. Main Indications System Performance Information AC Output Power Production Percentage Or read more about SolarEdge Energy Bank featured our blogs main page. Yeah nah I am connected directly to the ethernet port (I only got my inverter 2 weeks ago so have always had to use ethernet) - @mihailescu2m does your ethernet stays up for more than 24 hours? (then 0.98 is rounded up to 1.0?). One method used for this purpose is limiting the export power: The inverter dynamically adjusts the PV power production in order to ensure that export power to the grid does not exceed a preconfigured limit. This integration connects to your SolarEdge Webinterface via API - and collect relevant information in certain intervals. There are additional integrations which you can setup with HACS - such as the SolarEdge Modbus by binsentsu I have a slightly different setup: RS-485-1 and RS-485-2 are both in use. Sometimes I was disconnected couple days and made connection without problems, Same here every time I tried to connect, I was able to grab a socket. If you have a SolarEdge HD Wave or A-US Inverter displaying error codes or a SetApp inverter displaying a red fault light, then power cycling is a good next step. Changed the rs485-1 to solaredge Meter,sunspec protocol and ID Device 1. I would expect to see my system occasionally produce 6 kWh , but it seems to max out at about 5.3 kWh. The sequence that seems to restart Modbus TCP is 1. From documentation: [the active power limit] is set as the percentage of the inverters maximum power. Look for a grey box labeled AC Disconnect with a lever that youll pull down into the off position. I'm not having any luck with Modbus TCP on my SE10000H-AU000BWU4 (screen less) with firmware 4.7.26. and the better question, why did they do it in the first place? My rep sent me the full list of equipment being installed and I also see SolarEdge 7600H as the inverter. I have what I believe is the first install of the SolarEdge whole home backup unit, delivered just a few months ago. Control your consumption with SolarEdge US Export Limitation option, and learn about the many benefits of this option to your energy management. I personally wouldn't add anything unless you have cash spilling out of your pocket, maybe you do, but I'll bet the reason why that inverter shut down was because of just one extra panel in the string causing the overload. Maybe powerLimit is DC_Power*100/AC_Power? {"preview_thumbnail":"/sites/default/files/styles/video_embed_wysiwyg_preview/public/video_thumbnails/ebVWlL-ff7s.jpg?itok=G9pSHOU0","video_url":"https://youtu.be/ebVWlL-ff7s","settings":{"responsive":1,"width":"854","height":"480","autoplay":0},"settings_summary":["Embedded Video (Responsive)."]} Setting RS-485-2 to SunSpec, 2. I suggested the larger inverter so it is not run at the absolute limit. Q: Does SolarEdge Energy Bank automatically switch to backup during an outage? The first screen is the most important: For more detail, see this PDF from the manufacturer: What the lights on your SolarEdge inverter mean, Your inverter is communicating with the monitoring platform. I managed to set the Active Power Limit and the inverter behaves as expected. Shouldn't the optimizers and inverter work together to avoid overloading, including bypassing panels if necessary? This is located outside next to your utility meter. Will report my progress back here. This would be a reasonable concern if I was involved in the decision making for the inverter and the price was dependent on that choice. Production Limitation on SolarEdge's SetApp Enabled Single Phase Inverters with HD-Wave Technology And then within those, I picked the days with the highest peaks. 0.7 would be 1 as well). first year degradation will likely be close to 1%. Thanks. Thoughts? Its only a matter of time before your prospective customers join the search if they havent already. #upaWr#R!AQNHi`p +^R^4^W6C3?HS~2 L.A;' &Ww Copyright 2006-2022 Tesla Motors Club LLC. I just checked the stats on the inverter. The following tables detail the possible LED and switch combinations, and what they mean. As a result, you can simply add more modules, or more kWs, per string and reduce strings per sitethat means fewer MPUs and up to thousands more in your pocket for every Energy Hub+Energy Bank install. Check out our quick video on weathering a storm-related power outage with Weather Guard. Weeks of delays and costly, invasive construction associated with MPUs could easily lead to prospects jumping ship simply to avoid the headache. They did this when I called in with a storage profile issue and the tech noticed that I didn't have the latest inverter (or LG battery) firmware. The first step is to power cycle your inverter. There is an Import+Export meter attached to RS485-1 (Meter 1, Device ID 2) Usually this is due to night time, snow cover, and large obstructions. That means you can add on battery or EV charging without the need for an MPU. Initially Modbus TCP was giving timeout errors as it has for others commenting here. ON/OFF: Indicates the position of the inverter ON/OFF switch. SolarEdge API 3 . Also, the inverter efficiency reduces as the power drops so, if you have a higher rated inverter, it will spend more time at lower efficiencies. The solution is get a bigger inverter - 14*440 = 6160 and that is more than the manufacturer listed string power limit of 5700, you have hard proof your installer failed to properly design your system. I have another field, Power Limit %, set to 100, which I believe means I am not intentionally limiting the power on my end. edit: -> remote configuration via local API only available when SetApp (Android App) is supported by the inverter (common on the new ones). I am in touch with a SolarEdge engineer who is trying to help, and I have told him I suspect a firmware bug that I hope can be quickly fixed. hZko+1A q0u[qc7-BeIh)r%%2>fg.i&c>03esF,=f.0`Y.XLH gC5OrW$=x@zA"^gTI^c*%b hA6 It's got 30 Panasonic 325w panels for a total system size of 9.75Kw. Did anyone managed to control the inverter over modbus? (default = 60) Channels Available channels depend on the specific setup e.g. By using our website, mobile applications, or any of our online products and services (Services), you consent that we can access, collect, store and use cookies and your IP address in accordance with our Cookies Policy. Three Phase Inverters with Synergy Technology, Inverter is communicating with the monitoring platform. I am getting the 24hour issue - To fix I login via the inverter hotspot - turn off modbus tcp - wait a minute and turn it back on - it starts working again after a few minutes.. I didn't check if it is possible to reconfigure Modbus over Ethernet through a serial (RS232 / RS485) connection, but if you have serial you shouldn't need ethernet anyway. It may not display this or other websites correctly. Will report my progress back here. hbbd```b``"[Q,"lh2 they are well able to handle 79F air temps. hb```|B ce`ax ;&?00UA\+s?}r}om'csC%~\+{ue;oW}PV{nl h``R*@,[a,$l@w-0i 003jI~z ~5%}mgx#d/=w|tk9yUR@,dUw!2if`0V4(3\Qp p This is located either above the black dial/DC disconnect or on the left side in the back of your inverter. if a meter and/or a battery is present. PDF Last update: May 2016 - Kansas State University Some installers (seen some even mention it here) think that that is license and even recommendation from SolarEdge to install 135% over. As a thank you for your contribution, you'll get nearly no ads in the Community and Groups sections. Now some Modbus TCP requests were responding. @marpi82 did you run into the 120seconds issue by lesinigo ? My network has also gone down (upgrades,etc) since then and I have never had a problem establishing a connection. 3) Turn off the DC disconnect. And then within those, I deleted some that had sporadic cloud cover. endstream endobj startxref Example Scenario endstream endobj startxref For more detail, see this PDF from the manufacturer: SolarEdge Inverter status screens, If the blue light is on: Your inverter is communicating with the monitoring platform. Site Power Flow . Only problem I have is wrong LL voltage level read from meter - I have created RMA on SE Support and waiting becouse when I connect directly to meter by USB->RS485 converter all values are ok. I am in touch with a SolarEdge engineer who is trying to help, and I have told him I suspect a firmware bug that I hope can be quickly fixed. jIk"DB @mulles, no, after my solar company installed the inverter it was at least 12 hours before I attempted to connect tot it from code. In july 2016 SolarEdge published a document https://www.solaredge.com/sites/default/files/sunspec-implementation-technical-note.pdf on sunspec protocol. powerlimit: after observations from today (10s modbus data aggregated to 5m vs 5m solaredge api data) it seems that indeed what they call powerlimit is DC power % relative to rated power. My inverter still has the LCD screen. 1140 0 obj <> endobj like a timeout error if you don't ask for data after opening a connection). The text was updated successfully, but these errors were encountered: The Sunspec protocol does not include any of the module (optimizer) level data because that is proprietary to SolarEdge. About PowerLimit: it could be DC power but it would be a stupid choice. Can you explain how you did this? @mulles In our second post in this series, we further explain why installing our award-winning SolarEdge Energy Hub inverter along with our new residential battery, SolarEdge Energy Bank, can be less costly for your business. I simply negotiated my price per watt (by price matching a better deal from a local provider) after that, Tesla did everything. %PDF-1.6 % Main Inverter Status V a c [ V ] V d c [ V ] P a c [ W ] Daily Limitation Use of the monitoring server API is subject to a query limit of 300 requests for a specific account token and a parallel query limit of 300 requests for each specific site ID from the same source IP. Well, cosPhi can't be 0. The inverter will start to turn back on and may take a few minutes to reboot. If XXX and YYY are not equal, there may be a problem in one or more power optimizers. I would need to make more observations in low light conditions however, that's when i noticed the powerlimit is noticeably higher than ac power. I have a slightly different setup: RS-485-1 and RS-485-2 are both in use. hX[O[9+~ls|_ endstream endobj 701 0 obj <>stream the values from modbus tcp shows it's mostly ~0.98 - seems dumb from them to convert it to an int (then e.g. Have contacted SolarEdge support, but haven't got a response yet and judging by what others have said, it's unlikely I'll ever will. Beyond the SunSpec data, I did find additional holding registers with data in the 60000 range however I have not been able to make a correlation if its module data or not. By adding our new home battery, SolarEdge Energy Bank, to the SolarEdge Energy Hub platform, your residential customers will be able to access Weather Guard through the mySolarEdge app. It does not seem to handle multiple connections however single connections (regardless of the disconnected time) are no problem. endstream endobj 699 0 obj <>stream system reboot), it will have just 120 seconds to reconnect. If there is a violation of a specific API validation, the HTTP 403 - forbidden status code is returned. tGGcEd` ;`L All SolarEdge inverters have a red ON/OFF toggle switch and a black DC disconnect dial. When installing 375W modules in conjunction with a 40A main panel breaker, legacy AC-coupled technology will usually only allow 13 modules per 20A string, for a total of 9.75kW (or two strings). If youre currently installing legacy AC-coupled solutions, this trend may be especially working against you, as that technology can limit the number and size of modules, or kWs, per 20A string. Setting RS-485-2 to SunSpec, 2. Choose Protocol SunSpec (Non-SE Logger), also under that set Device ID to 1 (mine was set to 5). Once I've seen 'inverter status:power limitation', but normally it's 'production'.
