Starting with the firmware from Feb 2022, modbus TCP is disabled on WiFi interface. The power limit can be set to any value between 0-100 [% of nominal active power]. I do have an issue connecting (using the sunspec python module) - if I try to read the data immediately after making the connection, I get an error - so I have to wait for 1s after making the initial connection before actual reading data. Thanks for this. This can happen if there is snow covering the system or at night. Now some Modbus TCP requests were responding. ;"{ad+T2 sr4q\7`; nNNm>1OR}_>9{\=~.MzxA9EsbsBRhy6l++' 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. . hbbd```b`` kJ "@$X!X5,/d XELVk ;l S_OK: The connection to the SolarEdge monitoring portal is successful (appears only if the inverter is connected to the server). Power On, 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.. SunCommon has installed several SolarEdge inverter models. You could the same with a RPi but the airport express is cheaper and doesn't need any configuration. ON/OFF: Indicates the position of the red inverter ON/OFF switch. This is an easy error to reset! Depending on the sun and panel orientation. Are you ready to boost satisfaction, referrals and profits with an award-winning solar & battery solution that keeps homes on longer in a power outage?

After that, I am reading new values every 15 seconds without problems. P_OK: XXX/YYY: This signifies the number of optimizers in the array and shows if any of those optimizers are not working. Of course, my total purchase price is a measure of the total watts produced OK really important update. . 4474 0 obj <>stream There are a number of data logger products available that will read this data https://sunspec.org/sunspec-certified-products/. 1196 0 obj <>stream Changing the port on Modbus TCP (I just alternate between 502 and 1502) and 3. Go over that and the warranty is voided. 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. In those cases, contact, How to read your SolarEdge inverter screen. Modern inverters, such as those made by Fronius, SMA, Enphase and Solar Edge, now have an excellent new feature that allows you to throttle back your grid exports to a pre-set limit (i.e. But the port accepts connections anytime. I can post the other values from the inverter status screen if they would be helpful. Zero shade too. I simply negotiated my price per watt (by price matching a better deal from a local provider) after that, Tesla did everything. 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. Control your consumption with SolarEdge US Export Limitation option, and learn about the many benefits of this option to your energy management. SolarEdge has limits on the amount of DC power allowed on the inverters. To date I have never had a problem connecting to the inverter with a single socket. Edit: documentation at https://www.photovoltaikforum.com/core/attachment/88445-power-control-open-protocol-for-solaredge-inverters-pdf/. SolarEdge Inverters - SunCommon Maybe they reduce it to 1 decimal? Inverter Status and System Performance Indications | SolarEdge If XXX and YYY are not equal, there may be a problem in one or more power optimizers. I am trying to aggregate the data to look like the one in the official API call for inverter technical data (https://www.solaredge.com/sites/default/files/se_monitoring_api.pdf page 35). The inverters Max output is actually 7.6Kw, so it must be set to 100%. Homeowners can also manually adjust their backup reserve setting giving them complete control and confidence. Do you value your experience at TMC? It ties two inverters together and allows connection directly into the full load of the home. 4) Turn off your systems AC disconnect. 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. It's got 30 Panasonic 325w panels for a total system size of 9.75Kw. You have to reactivate it by restarting ModbusTCP(disable and enable it again) The port won't accept connections otherwise and appears closed on port scan. 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. Verifying Inverter Status - SolarEdge The Active Power menu includes the following options: Power Limit <100%> Current Lim<15.7A> Wakeup Grad <En> Grad Time <xxxxs> P(f) P(V ) Use the Active Power menu to control the inverter active power: Power Limit - limits the inverter maximum output power. ), @marpi82 did you run into the 120seconds issue by lesinigo ?

All of my panels are going to be facing south west. 0.7 would be 1 as well). The script example.py provides a minimal example of connecting to and displaying all registers from a SolarEdge power inverter over Modbus TCP . and the better question, why did they do it in the first place? Inverter Status and System Performance Indications Your inverter has a switch and three colored LEDs that indicate system information, such as errors or performance.

Across the nation, severe weather fueled by climate change is pushing aging electrical systems past their limits Last year, the average American home endured more than eight hours without power, according to the U.S. Energy Information Administration more than double the outage time five years ago. The Washington Post. That means you can add on battery or EV charging without the need for an MPU. My solution: I've bought a cheap second hand Airport Express (30$), placed it next to the inverter and set it to bridge mode. I didn't check if it is possible to reconfigure Modbus over Ethernet through a serial (RS232 / RS485) connection, but uf you have serial you shouldn't need ethernet anyway.

I am using ModbusTCP for about two years without problems and can confirm this behaviour. 3) Turn off the DC disconnect. 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. Power On, Boost satisfaction, referrals and profits by delivering homeowners the confidence to live uninterrupted in a storm-related power outage with our new app feature, Weather Guard. The inverter has a rated AC output of 6 kWh. edit: -> remote configuration via local API only available when SetApp (Android App) is supported by the inverter (common on the new ones). you might be able to tell more by looking at them individually on solaredge site. S_OK: Means that the connection to the SolarEdge monitoring portal is successful (appears only if your system is equipped with monitoring equipment and the inverter is connected to the server). Part 3: Uninterrupted ProfitSolarEdge Energy Bank. Copyright 2014 SolarReviews All rights reserved. This is the black dial right on the front of the inverter. 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 . By adding energy storage to your installation, in the form of a SolarEdge Energy Bank battery, for example, you will help homes harness power for more appliances, longer, in an outage, and access more free, clean solar anytime whether it is sunny or cloudy on any given day. The problem: Modbus TCP dies about every 24 hours and starts timing out again, requiring the whole sequence to be repeated. 2) If your inverter has a screen, wait until the DC voltage reading goes below 50 VDC. jIk"DB 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. No it is indeed closed. Will report my progress back here. My rep sent me the full list of equipment being installed and I also see SolarEdge 7600H as the inverter. The meter shows up in the inverters RS-485 status menu as RS485-1 Dev=MLT Prot=01 ##=01. If your panels are in different planes (east, west, south) then it probably wont matter since you arent producing over 7600 watts at the same time. There are some error codes (Ground Faults and Isolation Errors) where it does not make sense for safety reasons.
