209 Remote System Checkup Procedure

210 Note: Remote Pairing Document the status before/after the pairing procedure: Write down number of communicating optimizers ( last measured column in the table below the layout) To perform the pairing (best around peak-time) right-click on the inverter and select Choose Operation, Pair 13:00 30min after pairing, refresh your browser window Verify that no optimizers lost their communication 211

211 Site List Information Site was created, but did not send any data, yet: Site was communicating, but is currently not communicating: Site has one or more low alerts open: (single panel) Site has one or more medium alerts open: (single panel or string) Site has one or more high alerts open: (inverter/string not producing) 212

212 Finding Sites with Issues Not all issues will trigger an alert. In those cases you can look at kwh / kwp ratio compared to sites nearby / 9.71 = / 5.2 = / 5.2 = 1.79? 9.2 / 4.16 = 2.21 Note: Different orientations and shading scenarios will also affect this ratio 213

213 Step 1) Check Inverter Level 1a) Inverter Communicating? 1b) Inverter Producing? 1c) Inverter Underperforming?

214 Step 1a: Inverter Communicating? How to identify? not communicating OR not producing If the No data from Inverter alert rule is enabled: 215

215 Step 1a: Inverter Communicating? How to troubleshoot! Was the inverter previously replaced without updating the serial number in the monitoring? Go to Admin Logical Layout to correct the serial number of the swapped inverter Contact the customer to check: If the inverter is on (push LCD button) Inverter s AC is turned ON Internet connection is working Inverters system status screen is showing S_OK If S_OK is showing, but the monitoring is not showing data from this inverter contact SolarEdge If S_OK is not showing, check the inverters communication status screen for details on the communication state 216

216 Step 1b: Inverter Producing? How to identify? not communicating OR not producing communicating not producing! 217

217 Step 1b: Inverter Producing? How to troubleshoot! Check the inverters DC voltage in the table below the layout If Vdc = safety voltage, check: ON/OFF switch is in the ON position System is paired? -> re-pair! If Vdc is higher than Vdc nominal for long periods of time: check in the Layout for inverter errors check if the inverter displays an error inverter DC voltage 880V = stuck at startup voltage due to error 750V = nominal voltage 3-phase inverter 218

218 Step 1b: Inverter Producing? How to troubleshoot! Check if the design is according to SolarEdge design rules If less than the minimum number of optimizers are installed, it is possible, that the inverter does not start up due to not enough DC voltage. Fix the design and re-pair the system. Check the inverter for errors Right-click on the inverter in the layout, select Info and check System data and Errors for possible error messages. AC voltage & AC frequency errors can be due to a wrong country setting of the inverter 219

219 Step 1c: Inverter Underperforming? How to identify? compare between inverters:? compare between sites: / 9.71 = / 5.2 = / 5.2 = 1.79? 220 Note: Make sure to understand the shading & orientation of a system before judging its performance

220 Step 1c: Inverter Underperforming? How to identify? Select a sunny day, when checking a system! This makes finding issues much easier. 221

221 Step 1c: Inverter Underperforming? How to troubleshoot! Check for power clipping in the inverters AC power curve Check inverters DC voltage for verification (DC well above nominal voltage) inverter power inverter DC voltage 222 AC clipping can be due to: undersized inverter (unless intended, install larger inverter) smart energy management limiting the output (correct system behaviour) overheating (clean fan/heatsink, check clearances) a technical / configuration issue (contact SolarEdge)

222 Step 1c: Inverter Underperforming? How to troubleshoot! Power curve looks scattered despite perfectly sunny conditions The inverter might be shutting down due to an error. 223 In the layout, right-click on the inverter and select info. Check the Errors tab. Check inverters display for error code

223 Step 1c: Inverter Underperforming? How to troubleshoot! Inverter produces a lot less than other inverters on site Possibly a problem with one of the inverter s strings. (Verify later in step 2) inverter power 224

224 Inverter Examples

225 Inverter Example 1 Underperforming string? 226

226 Inverter Example 1 Switching the timeframe shows that all modulesmproduce roughly the same 227

227 Inverter Example 1 Layout view at 10:30am 228 By looking at the module power charts, we can see that the arrays are set up in an east/west configuration

228 Inverter Example 2 Inv 13 underperforming from 14:00 until 17:00 229

229 Inverter Example 2 produces less power V DC significantly higher than nominal voltage 230 A clear indication of power derating (dynamic) (temperature de-rating, smart energy management)

230 Inverter Example 3 P AC curve flat between 9:30 and 13: First indication of power derating

231 Inverter Example 3 V DC significantly higher than nominal voltage 232 Confirmation of power derating (static) (Inverters AC limit, configured power/current limit)

232 Inverter Example inverters start 1h later than the other inverter

233 Inverter Example If an inverter is not producing power, but the DC voltage remains higher than the nominal DC voltage an inverter erroris likely here: Isolation fault

234 Inverter Example 5 All inverters dropping in power = very likely clouds Inverter dropping to zero = inverter restarting 235 In this example: Inverter tripping due to wrong country setting. Frequency or voltage error.

235 Step 2) Check Optimizer Level 2a) Optimizer Communicating? 2b) Optimizer Producing? 2c) Optimizer Underperforming?

236 Step 2a: Optimizer Communicating? How to identify? not communicating OR not producing If the Power optimizer shutdown alert rule is enabled: 237

237 Step 2a: Optimizer Communicating? How to troubleshoot! Was the optimizer previously replaced without updating the serial number in the monitoring? Check the logical layout to see all operating optimizers Go to Admin Logical Layout to correct the serial number of the swapped optimizer Contact the customer to check: the panels for snow coverage, damage or extreme shading the P-OK number on the inverter s display during daytime If the P-OK number is too low, there is a technical issue on site. Send technician If the P-OK number is correct, there is an issue in the monitoring. Call SolarEdge 238

238 Step 2a: Optimizer Communicating? How to troubleshoot! Problem not solved? Measure safety voltage of the string 8.07 V Measure safety voltage of the not communicating optimizer 1.00 V Measure voltage of the panel that is connected to this optimizer 37 V 239 Perform pairing

239 Step 2b: Optimizer Producing? How to identify? not communicating OR not producing 240 communicating not producing!

240 Step 2b: Optimizer Producing? How to troubleshoot! Only a single/few optimizers not working? perform pairing to reassure that the optimizer is listening on the correct frequency for the wake-up signal from the inverter. Whole string of optimizers not working? Minimum number of optimizers not reached? Check if the string was designed according to the SolarEdge design rules Re-design Re-pair 241 Check on-site all series connections of the string: Cable, connectors, combiner boxes, DC-disconnects,... A loose connection might allow the communication signal to pass, but not allow a significant current to flow for power production. Contact SolarEdge for support

241 Step 2c: Optimizer Underperforming? How to identify? compare between modules:? Note: Make sure to understand the shading & orientation of a system before judging its performance 242

242 Step 2c: Optimizer Underperforming? How to identify? 4 ways to identify shading: 1) Check panel s Power chart Shading is often only occuring a certain times of the day Panel power reduced panel power until 11:00 243

243 Step 2c: Optimizer Underperforming? How to identify? 4 ways to identify shading: 2) Check Optimizer Voltage chart (output voltage of optimizer) One optimizer shaded: unshaded optimizers will increase output voltage shading gone after 11:00 shaded optimizer will reduce output voltage Optimizer Voltage 244

244 Step 2c: Optimizer Underperforming? How to identify? 4 ways to identify shading: 2) Check Optimizer Voltage chart (output voltage of optimizer) Multiple optimizers shaded: panels unshaded between 9:00 and 11:00 shade moves across panels Optimizer Voltage 245

245 Step 2c: Optimizer Underperforming? How to identify? 4 ways to identify shading: 3) Check panel s Voltage chart (output voltage of panel) Shading causes the optimizer to pick a different MPP shaded panel with different MPP Panel voltage 246

246 Step 2c: Optimizer Underperforming? How to identify? 4 ways to identify shading: 4) Use the Layout s playback feature 247

247 Step 2c: Optimizer Underperforming? How to troubleshoot! Optimizers at max Vout for long periods of time Optimizer voltage These optimizers operate at their voltage limit, and can not deliver the panels full power to the system They are blocked Blocked optimizers: Check the design (minimum number of optimizers per string). Increase the number of optimizers (according to the design rules) (e.g. by combining 2 strings in series) 248

248 Step 2c: Optimizer Underperforming? How to troubleshoot! Module mismatch The optimizers measurement tolerances will cause a slight mismatch in the charts Soiling can have a strong impact on the mismatch If the mismatch grows over time (measured with clean modules), it might be necessary to check the modules IV curves Panel power 249

249 Step 2c: Optimizer Underperforming? How to troubleshoot! PID effect (potential induced degradation) The module power decreases from + to - of the string Check modules Module connected to the + of the string Panel power Panel voltage 250 Module connected to the - of the string

250 Step 2c: Optimizer Underperforming? How to troubleshoot! Defective bypass diode One panel lost 1/3 (or 1/6)* of its power. Verify that the drop in power is caused by a drop in panel voltage. Check panel s bypass diodes Panel power 251 * Note: Standard panels with 3 bypass diodes will typically lose 1/3 of their voltage. With P600/P700 in 2:1 configuration, you will see a voltage drop of 1/6. Panel voltage

251 Step 2c: Optimizer Underperforming? How to troubleshoot! Whole string of optimizers not working at full power? Check on-site all series connections of the string: Cable, connectors, combiner boxes, DC-disconnects,... A loose connection might allow a small current to flow, but cause arcing at higher irradiances. This can cause erratic optimizer behavior (string shutdown and restart). Also AFCI errors might occur. 252

252 Optimizer Examples

253 Optimizer Example 1 All modules dirty clean modules = +12% dirty modules 254

254 Optimizer Example 2 Module underperforming 255

329 Isolation Test Procedure

330 Isolation Test This procedure describes how to locate and fix isolation problems along the DC path Isolation faults are detected by the inverters test mechanisms, which causes the inverter to stop power production and display Error 25 (1-ph) or Error 121 (3-ph) This procedure measures the resistance of the strings, optimizers and modules to GND, allowing the technician to locate and fix isolation faults Option 1: Using the inverter s built-in isolation test Option 2: Using an insulation resistance tester (Megger tester) 331

331 Built-In Isolation Test Option 1: Inverter built-in isolation test Procedure: Note: The following measurements must be done for each string individually. If more than one string is connected, switch OFF the inverter and disconnect all but one string Switch inverter ON Wait for the DC voltage to increase LCD button To measure the string resistance, Press and hold the LCD/OK button When the screen Keep holding button for pairing, release to enter menu appears, release the button Short-press to scroll down to Maintenance - Long-press to enter menu Navigate to Diagnostics -> Isolation Status 332

332 Built-In Isolation Test The asterisk (*) and the percentage indicate the approximate location of the fault within the string To locate the faulty component, multiply the number of optimizers in the string by the measured percentage e.g. 15 optimizers x 0.40 = 6 -> optimizer 6(±1) from DC+ Note: This will only work if no more than one isolation fault is in the system 333

333 Built-In Isolation Test Turn the inverter OFF Bypass the suspected optimizer+module combination and test again to check if the problem is solved Turn the inverter ON If the inverter produces power now, the fault is in the removed components To check if the fault is in the module or the optimizer, reconnect only the suspected optimizer, leave the module disconnected and run the test again If the inverter produces power, the fault is in the module If the inverter fails to start power production, the fault is in the optimizer 334

334 Isolation Resistance Tester Option 2: Insulation resistance tester (Megger tester) Required tools: Insulation resistance tester (500V 1000V) Adapters/branch cable to connect tester to strings/modules/optimizers 335

335 Isolation Resistance Tester Only qualified electricians should use this procedure There is high risk of electrocution Procedure: Turn the inverters ON/OFF switch to OFF Wait until the DC voltage drops below 50V Switch off the inverter AC voltage using the circuit breaker in the electrical cabinet Disconnect all DC string cables from the Inverter Adjust the Insulation tester to 500V When testing any part of the system that contains optimizers, use a branch cable to connect + and - together 336
