3 Trubleshting Meter Cnnectin Trubleshting Meter Cnnectin SlarEdge revenue grade inverters have a built in Revenue Grade Meter (RGM). This sectin describes hw t trublesht meter-related installatin and perfrmance errrs. Cmmunicatin Status Screen Trubleshting The meter cnfiguratin is set autmatically when activating the inverter using the activatin card. The cmmunicatin status screen shuld display the fllwing: w w w w w w w w D e v P r t # # R S < M T R > < W N > < 1 > R S < > < - - > < - - > Z i g B e e < > < - - > < - - > Device Type and Prtcl are cnfigured incrrectly If MTR (meter) is nt displayed as the device type (DEV), and WN (WattNde) is nt displayed as the Prt (prtcl), the inverter precnfiguratin has been verriden. This may be a result f inverter activatin r cmmunicatin bard replacement withut backing-up and relading the parameters. Cnfigure the meter as fllws: 1. Select Cmmunicatin è RS485-1 Cnf è Device Type è Revenue Meter. 2. Select Cmmunicatin è RS485-1 Cnf è Prtcl è WattNde. 3. Select Revenue Meter è Meter Func. è Prductin. 4. Check that the Device ID under Cmmunicatin è RS485-1 Cnf è Device ID is set t 1. Number f devices is nt displayed If <--> is displayed under the ## clumn in the Cmmunicatin status screen shwn abve, the meter is nt cmmunicating with the inverter. Check the fllwing: The meter cnfiguratin is as described abve. There are n lse cnnectins at the inverter cnnectrs and at the meter, specifically the RS485 wiring. Figure 1: Example f a lse meter cnnectr The wiring between the black 4-pin terminal blck n the meter and the RS485 terminal blck n the cmmunicatin bard is crrect, as shwn belw.

Ensure that prper utdr rated cmpnents are used. In case f damaged equipment, replace either the meter r the Safety Switch, as described in the next sectins. Use a Vltmeter t measure the vltage n the meter 10-pin terminal blck. The L1 L2 line t line vltage shuld be 240 Vac ± 10%. Meter Status Screen Trubleshting R e v e n u e G r a d e M e t e r S t a t u s : < O K > < E r r r M e s s a g e > T t a l [ W h ] : X X X X X X X <OK> is nt displayed If <OK> is nt displayed in the Status line f the status screen shwn abve, the meter is nt cmmunicating with the inverter cmmunicatin bard. Check the fllwing: There are n lse cnnectins at the inverter cmmunicatin bard and at the meter. The wiring between the black 4-pin terminal blck n the meter and the RS485 terminal blck n the cmmunicatin bard is crrect (See Figure 2). Check fr water damage r sealing prblems: Inspect the entire cnduit run fr pssible pints f water penetratin, and fix leaks. Ensure that prper utdr rated cmpnents are used. In case f damaged equipment, replace either the meter r the Safety Switch, as described in the next sectins. An errr message is displayed If Cmm. Errr is displayed, verify prper cnnectin f: The RS485 cables and cnnectrs The AC cnnectin f the meter If a different errr message is displayed in the RGM status screen, cntact SlarEdge supprt (supprt@slaredge.cm). Ttal [Wh] value is nt advancing If the Ttal [Wh] value displays a steady value althugh the inverter is prducing pwer, check the fllwing: There are n lse cnnectins at the inverter cnnectrs and at the meter, specifically the AC wiring n the meter 10-pin cnnectr. The CT black and white cables are crrectly cnnected t the 6-pin cnnectr n the meter: White CT wire is cnnected t L1 CT Black CT wire is cnnected t L1 CT The L1 cable passes thrugh the CT in the crrect directin (right t left), accrding t the arrw n the inside f the CT.

6 Replacing the Built-in Meter Replacing the Built-in Meter This sectin describes hw t replace the meter in the Safety Switch, and hw t cnfigure the cnnectin. Replacing the Meter 1. Turn OFF the inverter ON/OFF switch, and wait until the LCD indicates that the DC vltage is safe (<50V), r wait five minutes befre cntinuing t the next step. WARNING! If yu cannt see the inverter panel, r if a malfunctin is indicated n the LCD panel, wait five minutes fr the input capacitrs f the inverter t discharge. Si vus ne puvez pas vir l'écran de l'nduleur u si un dysfnctinnement est indiqué sur l'écran LCD, attendez cinq minutes pur que les cndensateurs d'entrée de l'nduleur sient déchargés. 2. Turn OFF the Safety Switch and the AC switch f the distributin panel. 3. Open the Safety Switch cver. 4. Carefully discnnect the three terminal blcks frm the meter: Green AC 10-pin cnnectr frm the right side Black RS485 4-pin cnnectr and black CT 6-pin cnnectr frm the left side 5. Release the tw screws cnnecting the meter t the pivting plate, and put them aside. 6. Install a new meter n the pivting plate and fasten the screws that were set aside. 7. Cnnect the terminal blcks t the new meter. Push firmly and verify they cannt be easily discnnected. Wiring the Meter If required (fr example, if yu discnnected the meter wiring) use the fllwing prcedure t rewire the meter cnnectins. Refer t Figure 5.

Turn OFF the inverter ON/OFF switch, and wait until the LCD indicates that the DC vltage is safe (<50V), r wait five minutes befre cntinuing t the next step. WARNING! If yu cannt see the inverter panel, r if a malfunctin is indicated n the LCD panel, wait five minutes fr the input capacitrs f the inverter t discharge. Si vus ne puvez pas vir l'écran de l'nduleur u si un dysfnctinnement est indiqué sur l'écran LCD, attendez cinq minutes pur que les cndensateurs d'entrée de l'nduleur sient déchargés. 2. Turn OFF the Safety Switch and the AC switch f the distributin panel. 3. Open the inverter cver. 4. Discnnect the DC and AC wires frm the inverter. If there are ferrite beads n the DC and AC wires in the inverter, pen them and set aside. 5. Discnnect the RS485 cnnectr frm the inverter cmmunicatin bard. 6. Unscrew the tw cnduit nuts in the inverter securing the Safety Switch t the inverter. 7. Open the Safety Switch cver and discnnect the DC and AC wires. Unscrew the tw cnduit nuts securing the Safety Switch t the external cnduits. 8. If the Safety Switch bracket is screwed t the wall, release it. 9. Carefully remve the Safety Switch with its munting bracket and RGM cmmunicatin cable frm the wall. Installing a New Safety Switch 1. Open the cnduit knckuts f the new Safety Switch (refer t Opening Cnduit Knckuts n page 1). 2. Psitin the new Safety Switch belw the inverter and frm the inside f the inverter grab the AC and DC wires extending frm the switch cnduits, as shwn belw: Figure 10: Inserting the AC and DC cnduits 3. Attach the Safety Switch with its bracket t the wall and slightly clse the screws. D nt ver tighten. 4. Insert the RGM RS485 cable thrugh the DC side cnduit f the Safety Switch and cnnect t the inverter cmmunicatin bard. 5. Securely screw the tw cnduit nuts nt the cnduit ends in the inverter. Verify prper cnduit sealing. Cnnecting the Safety Switch t the Inverter 1. If ferrite beads were remved frm the DC and AC wires, place them n the wires and clse them. Make sure the DC labeled ferrite bead is placed n the DC wires and the AC labeled ferrite bead is placed n the AC wires. 2.
