tkuehne (Thomas Kuehne) July 7, 2018, 7:54am #34 WN stands for WattNode, and your meter is a Wattnode Device. The only problem I have had is if I forget to disconnect my prometheus exporter from the server while I try to debug on on PC. The following tables detail the possible LED and switch combinations, and what they mean. (then 0.98 is rounded up to 1.0?). JavaScript is disabled. How about each string. Power On, Throw the AC lever or breaker back to the on position, turn the dial on the inverter back to the on position, and flip the red switch back to the 1 position. @mihailescu2m `LI8DL@(#VX Your inverter has a switch and three colored LEDs that indicate system information, such as errors or performance. To do this, unscrew the grey cover to access the breaker. It seems this is a setting in the inverter to limit the total output of the system, even if my panels are generating more energy at any given moment. Is there another reason the inverter would be intentionally underproducing? endstream endobj 699 0 obj <>stream Initially Modbus TCP was giving timeout errors as it has for others commenting here. SolarEdge is using cookies to improve your user experience. Improve Your Margins with More Modules The PowerLimit is used to curtail power injection upto a given limit or, in other words, to avoid that you push too much power into the AC grid. 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. ON/OFF: Indicates the position of the inverter ON/OFF switch. 5) Wait 30 seconds and then turn everything back on in reverse order. The sequence that seems to restart Modbus TCP is 1. https://www.solaredge.com/sites/default/files/sunspec-implementation-technical-note.pdf, https://sunspec.org/sunspec-certified-products/, https://github.com/dave92082/SolarEdge-Exporter, https://github.com/marpi82/sunspec_test/blob/master/modsunspec/result.txt, https://www.solaredge.com/sites/default/files/se_monitoring_api.pdf. 1196 0 obj <>stream Production Limitation on SolarEdge's SetApp Enabled Single Phase Inverters with HD-Wave Technology SolarEdge SetApp: Production Limitation - YouTube hTMO0+s\c;B*e,%v,;N\piwyAeQYPqOi)H'$ 48&0 J1an9U%0.V+QqHoCD}(J}p_4x2iWoz*]fs2d 8:EWUmWuzfOht=b[.&=] 5S&d8nhw}-j 32ikNbwIY38jH5A,GTNUkdDp8Q;)EQIB7;6/nS-w!HoEo^!1 I suggested the larger inverter so it is not run at the absolute limit.

My bet would be that Powerlimit is simply the % relative to rated AC power. Starting with the firmware from Feb 2022, modbus TCP is disabled on WiFi interface. Found out this the hard way. interval (minutes) in which aggregate data values are retrieved from Solaredge. 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. Finally - I can get optimizer data at 15-min intervals with a script that parses the monitoring website (from Layout/Playback), so this could be a good alternative for monitoring since it's not invasive and doesn't require any extra hardware, all software. 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. %PDF-1.5 % SolarEdge Energy Hub inverter and up to 3 Energy Hub Inverters per Backup Interface, for a maximum of nine batteries, delivering up to 30.9kW of continuous backup power. 4.Da^amemK4~mV TY)5vYElEt(}O F&1K2mY7 . Facing the growing possibility of a power outage, homeowners across the country, from Puerto Rico to Hawaii to California, are looking for more reliable ways to live uninterrupted and depend less on the grid. Is it possible your "remote" PC restarts/hangs i. e. and in this time there is no connection so ModbusTCP goes to sleep? Common error messages seen on SolarEdge inverters and how to fix them. Could you state, which Inverter Models you are using and maybe even firmware version? The inverter has a rated AC output of 6 kWh. From documentation: [the active power limit] is set as the percentage of the inverters maximum power. I see - I saw cosPhi always 1 or 0 in the data from the official API, whereas PF is ~ 0.98 in the modbus readings *2sv-~ w %%EOF 4396 0 obj <> endobj {"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)."]} I have a slightly different setup: RS-485-1 and RS-485-2 are both in use. This 120 seconds thing makes it unreliable (in my opinion) for unattended operations, so I just gave up the Modbus over Ethernet option and will try to use the RS485 connection. My network has also gone down (upgrades,etc) since then and I have never had a problem establishing a connection. Solaredge Inverter Status: Power Limitation : r/solar - Reddit 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. All numeric channels use the UoM feature . How many SolarEdge optimizers can be in a string? In our third post in this series, we explore the peace-of-mind benefits that come with installing ourSolarEdge Energy Hub inverter alongside our home battery,SolarEdge Energy Bank. There is a system error. to your account. Last question: Even though reconnect after connection loss works now. A w H4> 03,m^@!rF5N2f|||wI! @lesinigo According to #124 (comment) their might by a way to remotely "reset" the setting ? Now some Modbus TCP requests were responding. Found out this the hard way. Inverter Status and System Performance Indications Your inverter has a switch and three colored LEDs that indicate system information, such as errors or performance. because you have multiple inverters, your clipping will now show up as a flat line. 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. Changed the rs485-1 to solaredge Meter,sunspec protocol and ID Device 1. SolarEdge recommends that you don't exceed the maximum panel wattage rating of your system, so the actual number of panels that are connected in the string . I will check it in Detail. SolarEdge has limits on the amount of DC power allowed on the inverters. The first step is to power cycle your inverter. Maybe they reduce it to 1 decimal? Customized SolarEdge Energy Dashboard - Home Assistant Community But the port accepts connections anytime. ;"{ad+T2 sr4q\7`; nNNm>1OR}_>9{\=~.MzxA9EsbsBRhy6l++' @marpi82 did you run into the 120seconds issue by lesinigo ? This means my power is being clipped. One Tesla support rep told me they intentionally set this limit below the total system output level to increase longevity of the system. SolarEdge monitoring server supports both HTTPS/1.0 and HTTPS/1.1 protocols. Some installers (seen some even mention it here) think that that is license and even recommendation from SolarEdge to install 135% over. It ties two inverters together and allows connection directly into the full load of the home. Battery backup is the most reliable form of backup power for the home, according to SolarEdge North Americas Sales Education Manager, Michelle Spina offering more peace of mind when it comes to outages AND the wallet. 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. I won't make here a full description of active, reactive and apparent power but wikipedia is your friend. Thanks for this. 0.7 would be 1 as well). Any combination of LEDs on condition that the blue LED is on. endstream endobj startxref Look at it differently: Having the higher capacity array means proportionally greater output when not in the peak situation. If your inverter does not have a screen, wait for 5 minutes. As a thank you for your contribution, you'll get nearly no ads in the Community and Groups sections. This page was generated at 01:04 AM. Yeah I got it working in the end by playing around in the settings via the following sequence: @atze09 rather than using SetApp, your screened version be via the screen controls. We try to avoid clipping. jIk"DB 1140 0 obj <> endobj edit: -> remote configuration via local API only available when SetApp (Android App) is supported by the inverter (common on the new ones). SolarEdge has limits on the amount of DC power allowed on the inverters. Bottom line? 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). 4dRY All rights reserved. Btw: for me ModbusTCP is found in Ethernet Config and you don't have to change anything on Standard Modbus. 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. Some installers (seen some even mention it here) think that that is license and even recommendation from SolarEdge to install 135% over. %%EOF hZko+1A q0u[qc7-BeIh)r%%2>fg.i&c>03esF,=f.0`Y.XLH gC5OrW$=x@zA"^gTI^c*%b hA6 &/ja I havent had much luck figuring out what that means. One method used for this purpose is export limitation, which allows installing a larger PV system or a larger inverter without violating grid export (feed-in) limitations. PDF Export Limitation Application Note - SolarEdge I simply negotiated my price per watt (by price matching a better deal from a local provider) after that, Tesla did everything. We have long line runs back to the transformer here, and the . and the better question, why did they do it in the first place? Depending on the sun and panel orientation. Thoughts? Just want to report that inverter control over modbus is actually possible. if a meter and/or a battery is present. 4) Turn off your systems AC disconnect. P_OK: XXX/YYY: This signifies the number of optimizers in the array and shows if any of those optimizers are not working. For what it's worth, I'm not sure if the new inverter firmware has addressed the issue that @lesinigo was seeing however I was able to connect (and re-connect) via ModBus TCP reliably since my SE5000 was installed last week. There are a number of data logger products available that will read this data https://sunspec.org/sunspec-certified-products/. Modbus over LAN/TCP port 502 Issue #80 jbuehl/solaredge @dave92082 @marpi82 thx for sharing. hbbd```b`` kJ "@$X!X5,/d XELVk ;l Thank you awulf for this awesome hint! If XXX and YYY are not equal, there may be a problem in one or more power optimizers. About PowerLimit: it could be DC power but it would be a stupid choice. My solution: I've bought a cheap second hand Airport Express (30$), placed it next to the inverter and set it to bridge mode. Pac [W]: The AC output power this is the amount of electricity your system is currently producing in watts. *Whats oversizing? I would check that they have three strings within spec on each inverter. You could the same with a RPi but the airport express is cheaper and doesn't need any configuration.

You signed in with another tab or window. Arc Fault. Feel free to check it out if you are looking for real-time inverter data (without modules): https://github.com/dave92082/SolarEdge-Exporter, There is also original Sunspec python library written by Sunspec team HTTPS://github.com/sunspec/pysunspec/ and it is working with SE inwerters as with the other Sunspec enabled inverters (meters, baterries etc. 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. The problem: Modbus TCP dies about every 24 hours and starts timing out again, requiring the whole sequence to be repeated. Not only are you potentially losing out on serious revenue, but you could lose some customers, as well. 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.
